JQuery has got plug-ins from simple task like form validation to a lot of complex behavior. In this article I am going to discuss some of the very useful plug-ins of jQuery to do in place editing.   Jeditable   Jeditable is a very handy and small jQuery in place editor plug in . This plug in helps you make a lot of HTML elements directly in place editable with just a few lines of code This plug in can be downloaded from   http://www.appelsiini.net/projects/jeditable   You can also get more information about it on   http://plugins.jquery.com/project/jeditable     Once you have downloaded jQuery and jeditable using this plug in is very simple. I will start with a very simple e.g:-   Jeditable Demo click to Update Text Here This example creates a div element and clicking on it will make it editable. Once the user clicks on it and makes changes and clicks the data is posted to the script 'updatedata.php' (below the code for updatedata.php is shown).   In this example first I have created a <dev> element using <div class="div_txt" id="div_text">click to Update Text Here</div>       To make this element in place editable you just have to add     $(document).ready(function() { $('.div_txt').editable('updatedata.php'); });       The only mandatory parameter is the complete URL where the data will be posted when the user changes the content.( in our case its 'updatedata.php' or it could be http://abc.com/updatedata.php ) . My updatedata.php just echoes the value back so that it is displayed to the user back   <?php //Add Code here to $_POST['id'] and $_POST['value'] and update //in a database or file echo $_POST['value']; // Return the changed value so that is displayed to the user ?>     Adding buttons and tool tips   We can even add Ok and cancel buttons when the user tries to edit the content in place. So when the user clicks Ok the data is posted to updatedata.php . We can also add a tool tip which can give instructions to the user like âClick to editâ   So if I add a new div element to my page as follows <div class="div_txt_area" id="div_txt_area">Click on text here</div>   Then the following code   $('.div_txt_area').editable('updatedata.php', { type : 'textarea', cancel : 'Cancel', submit : 'OK', tooltip : 'Click to edit...' });   will add two buttons when the user is editing the text as Ok and Cancel . Also when the user hovers the mouse over the div the tool tip will be shown as 'Click to edit...'       Other Features   This plug-in has a lot of other features like To use selects in , in-place edition To specify a load url from which data is loaded in a Text area To post data to a function instead of an URL   You can read a complete list of features with code examples at http://www.appelsiini.net/projects/jeditable     Another In-Place Editor   An another good jQuery in place editor plug in is the âAnother In-Place Editor â   This is also a very good plug-in which makes HTML elements in place editable . This plug in can be downloaded from http://code.google.com/p/jquery-in-place-editor/   Once you have downloaded this plug in and jQuery using this plug-in is also very simple . An example to demo its usage is as follows   <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en"> <head> <title>Another In-Place Editor</title> <script src="jquery-1.4.2.min.js" type="text/javascript" charset="utf-8"></script> <script type="text/javascript" src="jquery.editinplace.js"></script>   <script type="text/javascript" charset="utf-8">   $(document).ready(function() { $("#div_text").editInPlace({ url: "updatedata2.php" });   });       </script> </head>   <body>   <p id="div_text"> Click to Update Text Here </p>   </body> </html>   Like the above example for Jeditable I have created one div element using <p id="div_text"> Click to Update Text Here </p>       To make this element in place editable with âAnother In-Place Editor â You have to just add   $("#div_text").editInPlace({ url: "updatedata2.php" });     This will make the element div_text in place editable and when the value is changed by the user and presses enter the data is posted to url parameter specified. (In our example it is updatedata2.php )   The parameters which are posted to the URL are   original_html; The original value in the element prior to the post update_value; The value which the user changed element_id; The ID of the current element <?php //Add Code here to add or update $_POST['update_value'] //in a database or file echo $_POST['update_value']; // Return the changed value so that is displayed to the user ?> The updatedata2.php just echoes the value back so that it is displayed to the user back   Adding a select for in place edit   We can even add a select in the in place edit so that the user can choose from options while editing. Once the user will select the value the data will be posted to url specified.   To do this I will have to create a div element   <p id="div_select">Click Here to Choose country</p> The following code will add a select to the in place edit $("#div_select").editInPlace({ url: "updatedata2.php", field_type: "select", select_options: "USA, UK , Australia" });   To add the select you will have to add the parameter field_type as"select" and specify the options in select_options parameter. Other Features Some of the other features of this plug in are Adding a saving image or saving text while the save happens on the server. This plugin allows to submit to a callback function rather than to the server URL This plug in allows validation of blank field For a list of more features you can visit http://code.google.com/p/jquery-in-place-editor/ Some other good jQuery in place editor plug-ins Following are some other jQuery plug-in which can be used for in place editor functionality contentEditable - http://valums.com/edit-in-place/ jQuery Edit In Place - http://josephscott.org/code/javascript/jquery-edit-in-place/ Editable - http://arashkarimzadeh.com/index.php/jquery/7-editable-jquery-plugin.html Conclusion jQuery and its plug-ins have really changed the way UI is developed for websites now. The plug in described in this article make is very easy to make a UI in websites where there is need In place editable elements. Adding in place elements just take a few lines of code with the use of these plug-ins.     http://www.codegravity.com/index.php?option=com_content&id=855 ORM frameworks in PHP - Introduction   ORM (Object ... http://www.codegravity.com/index.php?option=com_content&id=854 Introduction   ORM (Object Relational mapping) is a technique in which Objects oriented languages i.e Objects are mapped directly to relational databases. This is a generic concept which can be applied to any object oriented language like C++, Java, PHP etc and any relational database like Oracle, Mysql etc.   Object Relational Mapping Frameworks   Generally if you are working in a big web application you will have the data stored in some relational database. For e.g. If you are using PHP to build web applications there is a good chance that you would be using MySql as your relational database. As the application gets large dealing in with SQL in your PHP code gets very messy.   ORM frameworks are generally written in an object oriented programming language like PHP and map (or even generate) objects which directly map to relational databases.   So if you have an ORM object of customer and want to save it in your database the code required to do that would be some what like the following if you use an ORM frame work   $objCustomer = new Customer(); $objCustomer->name=âJohnâ $objCustomer->emaail=âjohn124@example.comâ; $objCustomer->save();   Some of the good Object Relational Mapping Frameworks in PHP   CakePHP       CakePHP is a rapid application development framework in PHP. You can download it from http://cakephp.org/ .   CakePHP has a support for developing application with ORM and MVC architecture. The licensing of CakePHP is flexible as it is distributed under MIT license. CakePHP is a complete Object oriented framework.   As CakePHP is a complete MVC architecture supporting framework it is an excellent framework to use specifically if a new application is to be started. CakePHP also has a good mechanism to define relationships between different objects and tables.   CakePHP has a feature called as CRUD scaffolding which with one line helps you create views for performing CRUD (Create Read Update Delete) operations once your modeler is defined.   Doctrine Doctrine is another good ORM framework in PHP. It can be downloaded from http://www.doctrine-project.org/ . Doctrine allows one to write database query in Doctrine Query Language (DQL) which is a dialect of SQL which is inspired by Hibernates HQL. This provided one with the flexibility to easily change backend database without much rework. Doctrine also has support for hooks. Hooks can be used to validate data which is stored in the database or which is retrieved from the database. Doctrine also has other features like a caching framework and also the ability to combine multiple PHP files in one which reduces the performance which is due to inclusion of many PHP file at runtime. Propel Propel is an ORM toolkit written in PHP. It can be downloaded from http://www.propelorm.org/ Propel is an open source framework which is under which is released under the MIT license. Propel has a component for source code generation which generated PHP classes on basis of datamodel definition language which is in XML. Propel also has a component which manages connections and transactions with RDBMS you are using. Propel has a features of easily describing relationship between different objects .It also has features to define database transaction in your code which will help you ensure database integrity and also improves the performance of database queries. CoughPHP CoughPHP is only an ORM framework in PHP. It can be downloaded from http://coughphp.com/ CoughPHP is not an MVC framework and hence is very light weight compared to other PHP frame works which provide MVC functionalities as well .As CoughPHP is not an MVC framework it does not affect the ways your views are built .Because of this it can be integrated into existing projects also easily . It is an open source framework and is licensed under FreeBSD license. CoughPHP generates all the PHP classes for the ORM mapping to the database. CoughPHP also provided hook like mechanism to validate or invalidate data before saving them in database. It also has support for specifying database transactions. Symphony Symphony is a MVC architecture web application framework written in PHP. It also has support for ORM .It can be downloaded at http://www.symfony-project.org/ Symphony is an open source framework which is licensed under MIT license. Symphony uses Propel or Doctrine as its Object Relational mapping layer. So if you are using Symphony you can use all the features which belong to Propel or Doctrine. As Symphony is a complete MVC framework it helps you create views controllers etc also. Symphony makes heavy use of other open source frameworks like Zend , Propel , Doctrine. So the features of these frameworks can be used when using Symphony. JavaScript frameworks like jQuery and prototype can be easily integrated as plug-ins in Symphony. Advantages of using a PHP ORM framework. Most PHP ORM frameworks generate code which is required for CRUD ( Create Read Update Delete ) operation on the database automatically . This helps in rapid development of the application as one requires to deal with only high level things of the application. The code for basic database functionalities is directly taken care by the PHP ORM framework In relational database you have a type like int, text, blog etc associated to each field in the database. Some times we have to convert the type on the fly from get data or storing data in the database from PHP code. This all will be taken care by the PHP ORM framework which is used in the project. As the PHP ORM frameworks are used by many people they are less likely to have security problems than hand written code specifically for your project. This protects your application from attacks like SQL injections etc. By using ORM frameworks there is no mixing of SQL code with business layer code of your application. This makes the code much easier to maintain. If during the lifecycle of the application the backend database needs to be changed then if a PHP ORM framework is will become comparatively much easier to perform a transition then if one was not using a ORM framework.       http://www.codegravity.com/index.php?option=com_content&id=854 Interactive HTML5 as flash banner replacement - Introduction H ... http://www.codegravity.com/index.php?option=com_content&id=853 Introduction HTML 5 is the new version of HTML.Like previous version of HTML this specifies the structuring and presenting content on the World Wide Web. But what we will roughly refer to as HTML 5 in this articles is actually the whole web technology stack (HTML 5 + CSS + JavaScript) and not only of the markup language. So when we talk of HTML 5 we have a programming language JavaScript ( like flash ) a set of api and JavaScript frameworks and the new multi media features of HTML 5 like drawing graphics ( using the <canvas> ) , play audio( using <audio>) and video ( using <video> ) Features of HTML5 for supporting Media HTML5 has added new features to HTML . To have a complete overview of HTML 5 and its features please visit http://dev.w3.org/html5/spec/Overview.html But the tags for media support which are very important are <video> tag The video tag defines a video or other video stream. <video src="myVideo.ogg" controls="controls"> Video Tag Not Supported </video> <audio> tag The audio tag defines sound, music or other audio streams <audio src="myMusic.ogg" controls="controls"> audio Tag Not Supported </audio> <canvas> tag The canvas tag is used to display graphics. Canvas is just a container. One can use JavaScript to draw in the container. <canvas id="drawCanvas"> Canvas Tag Not Supported </canvas> <script type="text/javascript"> var drawingcanvas=document.getElementById('drawCanvas'); var drawingcontext= drawingcanvas.getContext('2d'); drawingcontext.fillStyle='#FFFFF'; drawingcontext.fillRect(0,0,70,70); </script> Web Development trend towards open technology Web development is certainly moving towards open technologies and non proprietary standards like HTML 5. Moving towards open technologies becomes necessary for the developers specifically at client side technologies as they do not have control over it and are depended on what the client is using ( e.g. the client might be using IE on windows , or might be using IPhone to access the website ) . In such cases open standards and software are a better bet than a proprietary technology like Flash. It is seen that JavaScript frameworks like Jquery etc are continuously replacing flash at least in things such as animated menus and basic web animation. So basically web developers are now using Flash at least for lesser things than they used to use it a couple of years earlier. Software giants like Microsoft (which have there own proprietary Silverlight ) are also embracing open software like Jquery and are also going to make it a part of visual studio. So with the in a war of flash (a proprietary technology) competing with HTML5 (an open standard), HTML5 (the complete stack) has a much better chance of winning till the features both provide are similar. Also HTML 5 is render directly by the browser (flash is rendered through the flash plug-in), in case there are any bug in it they can be directly fixed by the browsers. The browsers donât have to wait for adobe to fix the bug in the flash plug-in. YouTube launches support for HTML5 One of the biggest site using Flash would be youtube . You tube launched support for HTLM5. The support is limited but this is a huge step towards HTML5. Screen shot of youtube without a adobe flash plug-in No flash on iPhones, iPods and iPads There is no flash support on iPhones, iPods and iPads. Apple has rather given support for HTML5 on iPhones, iPods and iPads . Steve jobs have shared his thoughts on flash and the reason behind not using as flash being a propriety technology and only adobe controlling it. So apple wanted to use open standards in their products ( i.e. on iPhones, iPods and iPads) You can read a detail reasoning given by Steve Jobs for this decision on - http://www.apple.com/hotnews/thoughts-on-flash/ Flash offers things that open web donât offer (may be also not in coming years) The HTML 5 (stack) is good for basic animations. But capabilities of Flash are still unmatched by far by any combination of open standards for higher end animation and interactive capabilities. Javascript also is very processor intensive currently. So here also Flash presents a better solution for the sites which have a lot of animations and high interactivity like gaming sites etc. Flash has a more than just video, flex currently provides a very rich programming model and create very rich interactive web applications. Also the Action script engine is very robust and efficient which contributes to the popularity of Flash. Developers can only move if the users move One another major hurdle in HTML 5 replacing flash is the developers can use these new standards only if the users of the web sites move to software which supports these new standards. Still a lot of users use IE6 to access websites which is quite an old technology. Though backed up by big software players HTML 5 video is also not mature enough still. Tools to create rich content for authors There are a lot of tools associated with flash to create rich content in flash. Some of these tools are specifically built and marketed by adobe itself. Such tools support is currently lacking for HTML5. This might not be a problem for developers. But authors who are not developers it would be a big problem if such tools are not present or easily available. Conclusion With all the factors mentioned above HTML5 ( stack ) at least in the recent years will replace flash for basic animation , but flash would still be a dominant technology for high end animation and interactivity applications on net . Total replacement of flash by HTML 5 in recent years looks highly unlikely unless some combination of open technologies can provide all sets of features provided by flash. But the use of flash will surely diminish as HTML 5 can do more and more things (like use of flash to do basic animation is greatly reduced) and if Adobe has to keep flash in the race against HTML5 and other open technologies it will have to continuously improve Flash and provide better features and capabilities the open standard can provide.   http://www.codegravity.com/index.php?option=com_content&id=853 Java Data Repository performance - Scenario: Itâs a common scen ... http://www.codegravity.com/index.php?option=com_content&id=852 Scenario: Itâs a common scenario that a web site rarely updates the background database but frequently access the database to fetch requested data. Consider the web site that provides the results of Secondary School Certificate exam of a country, based the population of that country the total number of students who attended the exam may be 2 million, 3 million or more. In India it may be more than 10 million. When the result is just published just think about the number of hits per second on that web site. A student just provides a Student Registration number and gets the result from the site. So should that web application search the database every time there is a request for result in that site? To me itâs a âNOâ. In the age of WiMax and 3G it is expected the website to appear in a twinkling of an eye. So if you can provide sufficient RAM to that web server why donât you use data repository. âData Repositoryâ? Yes. Data Repository: Itâs an implementation of virtual storage of a portion of a database or entire database. The concept is: Database (MySQL, SQL Server etc), Load the data in to RAM and refresh periodically à Response of the data query. For each subsequent database query, after the initial loading, the response is generated from the data loaded into RAM. So, there is no need to knock the database for every query. This is a quite faster approach. But remember if the database rarely has insert, update and delete operation this approach is very much efficient. If the there is a change in the database the change will be reflected in the database only after the data repository is refreshed. Implementation: So in a web server how would you implement that? Here is an example to implement Data Repository using Java and STRUTS framework. For simplicity I have omitted some minor parts such as import statement, portion to fetch data from Database in the reload() method. I have also omitted the details of the DataDTO class.   Implementing the DataRepository: /*********************** Start of DataRepository.java************************/  public class DataRepository  {  // 60 Seconds, you can change it s u like      public static final long REFRESH_INTERVAL = 60 * 1000;    static DataRepository repository = null;    private long lastRelodingTime;    //Its a map to get Result using Registration number as KEY    HashMap regMap;    private DataRepository()  {      forceReload();    }    public static DataRepository getInstance()  {      if (repository == null)        createDataRepository();      return repository;    }      private synchronized static void createDataRepository()  {      if (repository == null)        repository = new DataRepository();    }    private void reload()  {     // DataDTO is the clas to hold Registration Number,      // Name and CGPA of any student     // For simplicity here I havent added it.        ResultSet rs = null;        rs = ResultSet after database query     while(rs.next())     {       // DataDTO provides StudentName, Student Registration Number      // and student CGPA. You can add additional member variable      // or method for more details*/      DataDTO dto = new DataDTO();       dto.setName(rs.getString("name"));      dto.setCGPA(rs.getFloat("cgpa"));      regMap.put(dto, new Long(rs.getLong("registration")));      }          }    public synchronized DataDTO getResult(long registrationNumber)  {      checkForReload();      return (DataDTO)this.regMap.get(new Long(registrationNumber));    }    private void checkForReload()  {      long now = System.currentTimeMillis();      if (now - lastRelodingTime > REFRESH_INTERVAL) {        lastRelodingTime = now;        reload();     }    }    public synchronized void forceReload()  {      lastRelodingTime = System.currentTimeMillis();      reload();    }  }/*********************** End of DataRepository.java************************/  Look at the implementation, you canât directly create object of the DataRepository Class. The DataRepository class is an implementation of a singleton. So, there will be only one instance of the DataRepository Class. You should get the instance of the Class this way: DataRepository instance = DataRepository.getInstance(); The logic here is, you create a single instance of the class. Load the data from database to Java data structure inside the reload() method. The data loaded from the database is refreshed when a new request is made and the refresh time interval expires. Now the object of the DataRepository Class is loaded into the memory along with the data loaded from Database. Suppose, a student with registration number = 101 is looking for his result. You can provide the result without searching it again. DataDTO studentInfo ; long regNumber = 101; studentInfo=(DataDTO) DataRepository.getInstance().getResult(regNumber); String studentName = studentInfo.getName(); float studentCGPA = studentInfo.getCGPA(); If you are using STRUTS framework you can have Form Class that extends ActionForm. Say, you Form class name is DataForm. DataForm form = new DataForm(); form.setName(studentName) form.setCGPA(studentCGPA) Finally: Forward this DataForm to your Action class. You can use this architecture in any desktop, web or other server type application based on your requirements. http://www.codegravity.com/index.php?option=com_content&id=852 Pagerank prediction tool - I finally found some working p ... http://www.codegravity.com/index.php?option=com_content&id=851 I finally found some working pagerank prediction tool.

I was missing sychronization between the existing joomla users already registered 2. They were not simply embeddable into existing pages 3. Most of them were too complex 4. I wanted to have my custom fields with custom types an my custom email templates 5. There were not any good usable bug tracking components for Joomla   That's why I've developed my own simple bug tracking system for Joomla !   Well, I've spent some of my days off on this, instead of some other more enjoyable activity, but I hope it's worth it.

This component was a replacement for the AkoComment for Joomla 1.0. But after serveral days, I've realized that my site got spammed, even though this JoomlaComponent uses the CAPTCHA protection. The spambots somehow bypass this protection. I've created a modification to this JoomlaComment component, which uses the MathGuard protection against spam bots. This class I've used also with the AkoComment component. The advantage of MathGuard class is, that it's not so much wide-spread, and therefore, not many bots have mechanisms to bypass this kind of CAPTCHA. http://www.codegravity.com/index.php?option=com_content&id=839 Email as Image in PHP - This is a class which is diff ... http://www.codegravity.com/index.php?option=com_content&id=837 This is a class which is different than every other class you can find regarding coverting an email address to image.This is because it uses the encryption of the email addresswhich is being passed to the script which renders the image.

Developers can use this feature and enhance the tags that are provided by JSF implementations (e.g. sun, myfaces, etc). Or they can straight away start writing the tags of their own. Today we’ll see how easy it is to create a custom tag in JSF. Let’s try out with an example, to create a tag, which will display today’s date and a list of people who has birthday today. http://www.codegravity.com/index.php?option=com_content&id=836 Write paid blog posts about programming - tips and articles - I'm looking for skilled develo ... http://www.codegravity.com/index.php?option=com_content&id=835 I'm looking for skilled developers who can write technical articles for this popular website.The same way as they would do on their own blog but I can pay for their posts. Our portal is quite popular and at first places on google so this is also opportunity to introduce yourself. Short note about your person and your skills will be at the end of each of your article also with a link to your own website/profile.I'm interested in topics: >>HTML5, SVG, CSS3<<, Joomla CMS (creating components/modules), Java, Spring, JSF, IceFaces, EJB, Hibernate, Javascript frameworks, jQuery, SEO tips, Liferay portal, etc. Looking for a long term co-operation at reasonable prices. First I'd like to start with small tips/articles to see potential of developer, then giving him more responsibility for longer articles. The content should be unique, not copied from somewhere else. After I pay for an article, I buy this article including copyright. Paypal is required.Another thing what I'm looking for is some developer - native english speaker, preferably from US or UK, who can make corrections on existing posts by other users who are from other countries including me.

There was always a problem to run the source-code formatting in Eclipse, it was annoying to do it all the time. Fortunately, there's a plugin that runs this indentation and organizes the imports for you everytime you hit Ctrl+S (Save).Here's a link: http://eclipse-plugins.2y.net/eclipse/plugin_details.jsp?id=1162I use it in the BEA Workshop for JSP that is perfect when developing JSP + JSTL + Spring MVC.The main feature why I like it is a hot-deploy functionality. Everytime you save JSP or a .java class, it reloads it in tomcat and you can see your changes immediatel.   http://www.codegravity.com/index.php?option=com_content&id=830 CodeGravity.com has now Pagerank 7 ! - Dear visitors.

You will see the JoomlaWatch icon in the "Components" menu. Accessing JoomlaWatch Stats You will see the JoomlaWatch main window. This window consists of JoomlaWatch menu (1), Visitors (2), Bots (3), Weekly visits graphs (4), Daily and All-time stats (5). All of these information are updated in real-time. It means, that you can easily "watch" what's going on currently on your website. The main window of JoomlaWatch Latest visitors In this window you can see the "real users". Stats are updated in intervals specified in the settings. When there is some activity, it is highlighted by the yellow fading rectangle. In each row you can see: A "globe-like" icon. When you point your mouse over this icon, the map is being displayed, where is the actual location of the user. The map comes from the 3rd party service (default by http://www.netip.de) Then, there is country code Country flag IP address of visitor (you can click on this IP and toggle blocing of this user) Username (below the ip address) Browser icon (when you point your mouse over it, you will get the detailed browser information) Operating system icon (when you point your mouse over it, you will get the detailed browser information) Access time Title of webpage (when you click on this link, the webpage will open) URI of webpage (the relative webpage path) Came from information (shows how did the actual visitor got to your webpage) When the user visited more than one page, they are all listed there, with the actual time of the visit (as shown on a screenshot below). The latest "real" visitors Map When you point your mouse cursor over the "globe" icon, that's usualy at the very left. A new window will appear, opening a frame with a website that shows a location of this user on the map. During the time this window is open, everything behind it stops. This window will disappear, when you click somewhere else, and everything continues as before. A geographical map showing where the user came from Bots The same applies to "bots". Bots are usualy special programs, that access your website for special purpose. Some of them are good (such as google bot that indexes your website content), and some of them are not (several spambots, that gather e-mail adresses). This differentiation is made by a simple "trick". When someone is a real user, his browser loads the page source (HTML), plus immediately all images. Bots just load the HTML source, which they usualy parse. You can also see, that these bots usualy don't have any browser identification. Bots & spiders Visit stats This is a real-time updating statistics of your visitors. The heading displays the current week number and year. The current week is selected by default. There is a simple navigation - you can move backward and forward between weeks. Then, the table for selected week follows. For each row: on the very left, there is a date, plus the week day shortcut. Then, there are three information. The first one, displayed in blue color, displays the number of unique visitors for that particular date. The green data mean the pageloads (how many webpages the users have viewed). The last information (in grey) are hits. These hits are taking also the loads that comes from the bots. In the cell to the very right, there is a graphical representation of these data - as bar charts. The percentage is a ratio (unique/pageloads). The lower this percentage is, the more pageviews each user on your website makes. Visit statistics Daily stats This part shows the real-time updated statistical information for current day. You can also navigate to previous days. Each of the stats module shows the name, number of hits, an arrow, trends icon, graphical representation (a bar chart) and percentage. It contains just top 5 values. You can however see more values, when you click on "Expand" link. It shows 15 more records by default, but this number can be increased in the settings. At the bottom (Total:), there is a sum of all the data from this statistical part. First, there is the URI stats part. It shows the most popular webpages of your website. It's shown as the relative path (the URI [Uniform Resource Identifier]) Next module is the Countries module. It shows a flag and a country code of your visitors. Then, there are the Referers. The top domains, where your users came from The IP module show the most active IP adresses on your website. Some IPs are "too active". This can make more load to your website. When you point your mouse over the 'globe' icon, you can see, where is this IP from. The country flag is also helpful there. Daily statistics It's not all.. Then you can see the most active users. You can also click on the username, and the user detail will be opened. Goals are the special feature. It shows the top goal hits. For explanation, please see the Goals section. You can just click the goal name, and the form with that actual goal will be opened, and you can make some modifications to it. The next feature is, the Google keywords. You can see the top 5 most used keywords the user have used to get to your website from any google search. For now, just google is supported, maybe there will be some other search interfaces added in the future. Next, the top 5 browsers, with icons, and their statistics And last, but not least, the icons and names of most popular operating systems used by your visitors Daily statistics (continued) All-time stats When you click on the second tab, right next to the default "Daily" tab, you will see the all-time statistic. This statistic is made of all available data gathered from the time JoomlaWatch was installed. This is quite the same as the daily stats, except it takes a wider range. All-time statistics Frontend In the frontend, there are the country information, plus information about the unique visits for: Today, Yesterday, This Week, Last Week, This Month, Last Month and Total. You can hide these information in the Settings, in the "Frontend" section. JoomlaWatch Frontend showing the top Countries and Visitors information Settings In the settings you can alter several parameters concerning appearance, frontend appearance, history & performance, ignoring & blocking and some expert settings. All of the fields have the explanatory text with an example right next to it. Appearance & Frontend settings History & performance, Advanced, and Expert settings Reset all data At the very bottom, there is a link that resets all the data. This is good, when you want to start from scratch. Of course, there is a confirmation window to ask you whether you really wish to do that. Reset all data link, and the confirmation window Trends Green & red arrow icon You could have noticed some new icons next to each 'data' name. First one is the arrow icon. This icon indicates the increase or decrease or particular data - in our case (on screenshot), the visitors coming from extensions.joomla.org. This always the last yesterday's value compared to the day before yesterday. The arrow is green, when there's an increase, and red, when the value has decreased. When there is no change, the little gray dash (-) appears. The arrow icon and the trend icon Trend icon Right next to the arrow, there is a little blue trends icon. When you move your mouse cursor over it, the window appear (as shown on a screenshot below). "Trends" are in fact, vertical bar charts, that show how your data changed in time. First graph shows the daily changes, and the next one, the weekly changes. Below each bar, there is a percentage, indicating the increase or decrease from the previous day. The same is on the weekly basis. These data are available everywhere, where there is a trend icon. It applies to all kind of data - URI, referers, keywords, countries, and even goals. Trends (daily and weekly charts) for country: us IP Blocking You can block IP address, just by clicking on it. The confirmation is needed. When the IP is blocked, it's indicated by a strike-out. Blocked IP, plus the confirmation window IP Unblocking To unblock the IP, you can click on blocked IP again. If this IP already disappeared from the visitors windows, you can still find it at the bottom of the stats window (as shown on a screenshot below). There you can directly see the number of blocked attempts for each IP. Click "unblock" to unblock it. You can also enter the IP manually, by clicking the "Enter the IP manually". There, you can use wildcards as well. Eg. 217.* will block all IP starting with 217. List of blocked IPs, plus a window to enter a new IP manually Goals Goals.. Goals are quite handy feature when you want to get some more advanced information. "Goals allow you to specify special parameters. When these parameters match, the goal counter is increased. This way you can monitor whether the user has visited a specific URL, posted a specific value, has a specific username or came from a specific address. You can also block or redirect such users to some other URL.". On a screenshot below, you can see a table with several goals, their parameters, how many times the goal has been reached, and the action image buttons to enable/disable a goal, edit, and delete a goal. To create a new goal, click the icon with caption "New goal". The main goals table New goal You will get the blank form. This topic is quite advanced, and might appear quite complex, but actualy isn't. Every field contains a long description, so it should be quite easy to figure out what to put there. When you don't fill anything in, the condition is ignored. It means, that the more fields are filled, the more likely is this goal going to be reached. The best would be to make an example: Let's assume, we want to protect our website from some spambots Creating a new goal Goal example - protecting our Order form Let's assume now, that some bad guys posted a message about your website, on let's say: "badforum.org". The message states, that some of them has discovered, that you have a form on your website, and there is a possibility to flood this form with thousands of messages. This form represents an order form, and everytime someone submits the form, you receive a text-message about the new order. Your order form has an address: www.yoursite.com/order-form . However, this time someone wants to abuse it. Your order form is inacessible without registration, so they registered a user: botuser1. You have discovered, that they use special server somewhere in, let's say, Malaysia, for this purposes. The IP of their servers is 201.2.3.2, 201.2.3.3, 201.2.4.4.. This program they have made fills the order message about how fantastic the game "World of Warcraft" is, with tons of links to some inappropriate websites they own. So, with JoomlaWatch, you can do something against it, or agains some other attempts like this. Let's look at the filled form below: The first field contains the name of our goal, it can be anything. Then, there is the URI condition, that we are just checking whether they are trying to access a webpage with our form. Title condition is effective, when you want to protect several websites with some keyword in it. Then, their the username follows. Then, there is their IP address range, which covers all addresses mentioned above, just with one wildcard (*). Your form, when submitted, calls /order-form?form_action=submit_form. When you specify this, it will cover only the cases, when the form has been submitted. And.. when we look at the order form on our website, the field with named "order_message". (It's in the HTML source <texarea name='order_message'></texarea>) Finally.. we specify, where we want such bad guy to be redirected. In our case, it's some general server, or, if we do not want to forward him anywhere, we can just "block" him, and set the "Block" field to 1. Example: A goal to protect the order form Some information related to previous versions follow top referers: now you can see the daily and all time statistics where the most visitors come from Top domains refering to your website (24.03.2008): VERSION 1.2.5 - should fix errors of 1.2.4 like "blank page" and define notices- all the features from 1.2.4 (16.03.2008): VERSION 1.2.4 Version 1.2.4 had some problems with installation and many people reported a "blank page". The bad thing is, that for me it works well. But was unable to figure out what was causing the problems for so many users. New features in this version:- Was rewritten to work with both Joomla 1.0 and 1.5 (NOW NATIVE)!- IP statistics - can help you to identify spambots or users that make most requests- IP blocking feature: blocking of single IPs or using wildcard filter- A counter of blocked attempts for particular blocked IP- Introduced some new config parameters - Parameters now fully configurable in UI in back-end.- Flags show the whole country name in mouseOver- and many more fixes and improvements (17.03.2008): VERSION 1.2.4 - I got some complains like "Why do I have to enable the legacy mode, when it should work with Joomla 1.5", or "the Legacy mode sux..", and so on..- the thing was, that the you had to enable the legacy mode just because of a fact that two different versions of joomla use different XML descriptors (joomlawatch.xml in com_joomlawatch.zip)- finally, I found a "trick", I did not know about before. You can have 2 descriptors in one .zip archive - (joomla.xml and joomla.j15.xml). Pitty that I did not know that before.- but now it's fixed and it runs on 1.5 and 1.0 natively ! - so just please re-download and re-install from this day. Things you shouldn't forget: - When upgrading to a new version, all tables are being deleted, so if you want to keep the stats, make a database backup- Before installation, please make sure you have at least 20 MB of free space. - Don't forget to unzip the whole archive and then just use those .zip files for installation.- Now you don't have to enable the legacy mode in Joomla 1.5- You MUST publish the mod_joomlawatch module, to see users on your website.- make sure you did all of this, before you ask for help in forum or in comments. Thank you Possible problems with registrationSome users reported that when they wanted to register, the system has blocked their account.It's probably because you have to click the link recieved by an email to activate it.When you don't revieve this email, your domain is probably blacklisted, so try to use another email. If this still doesn't work, please write me a short email and I'll enable your account manually. Thank you. JoomlaWatch troubleshooting (check this first!) Sometimes even if the software is written correctly, some of the settings of the webhosting system might influence it's behaviour. It's also quite hard to predict many of the custom settings for each individual webhosting provider. Identify the source of the problem: 1. Access the files on your webhosting - get the connection details from your system administrator / webhosting provider: hostname, username, password a) Use Total Commander to access your remote files: - press Ctrl+N System will show the dialog with the new FTP connection Connect to (host or URL) - enter: yourlogin@yourdomain.com and press OK - Total Commander will ask you for the password - in one of the panels you'll see the files / directories on your remote host b) Use the webftp access to access your remote files - webhosting providers usually allow you to view the content of your remote directories via the web browser. It's usually accessible via the webhosting Control panel. - find out, what's the url in your case navigate to that url: (In many cases it's http://webftp.yourdomain.com, or http://ftp.yourdomain.com) - You should see the dialog asking you for the username / password - Enter your login / password and press ok - You should see the remote directories. You'll be able to navigate between directories and edit the files remotely via this web interface 2. Set the live site 1. Open the file /components/com_joomlawatch/config.php change # define('JOOMLAWATCH_LIVE_SITE','/'); to: define('JOOMLAWATCH_LIVE_SITE','http://www.yoursite.com'); (remove the # ) 2. Save and check whether it works 3. Enable the debug mode - Open the file /components/com_joomlawatch/config.php - Change the value: define('JOOMLAWATCH_DEBUG', 0); to define('JOOMLAWATCH_DEBUG', 1); Usually all the notices and messages are hidden, because every hosting has it's own level of PHP error reporting defined in php.ini. (E_NOTICES, E_PARSE, E_WARNING).. This setting sets the error reporting in JoomlaWatch to E_ALL (showing all messages) - check for the possible errors in your JoomlaWatch now (ignore the Notices, only check for Warning, Error) - you can anytime switch this debug mode back to 0 4. Check for Javascript errors - In your firefox browser click: Tools -> Error Console (or press Ctrl+Shift+J) - click on tab Errors, then press Clear - Now try to access the JoomlaWatch from administration and watch for Javascript errors - If there are some, try to set the Live site (2) and/or Debug mode (3). - Report your findings as a bug 5. Check Directory permissions - use the Total Commander or webftp to access your files (1) - navigate to the content of /components/com_joomlawatch/ - Set the directory permissions to 755 and file permissions to 644 (mark the directories css, flags, icons, js, lang, sql), then select from Total Commander menu: Files -> Change Attributes, instead of ---- write 755, press OK - Do the same with the files admin.joomlawatch.php, block.php, etc... intead of ---- write 644, press OK - navigate one level up (/components/ directory), and change the permissions on folder com_joomlawatch to 755 too. 6. Check the database - check whether your database isn't full. Some webhosting providers give you only the limited database space. JoomlaWatch is quite intensive in demand for the database space, because it stores the statistics from previous days. Access your database using phpMyAdmin - open your webhosting control panel. Usually you'll be able to navigate to the url with the phpMyAdmin - enter your database user name, database password - on the right side, you'll see all your databases (they have usually the same name as the database user name). Click on that particular database - in the right panel scroll to the very bottom of the page. Check for the Sum of your table sizes and make sure it doesn't exceed the space limit of your webhosting provider - make sure there are jos_joomlawatch_* tables and they don't exceed any limit JoomlaWatch Frequently Asked Questions (FAQ) When I open the JoomlaWatch back-end, I just see "Loading visits...", "Loading stats.." This is because the files in the folder /components/com_joomlawatch/ have the wrong permissions. Please change the permissions to this whole foder to 755. (Make them visible to everyone). To do this, you can use the Total commander Files->Change attributes, or the unix command: chmod 755 "folder". I cannot see the JoomlaWatch icon When you see an icon of a "broken image" instead, click it and choose "View image". You'll probably see a message: 500 Internal server error. I cannot do anything about this error, cause it's something wrong with your server's configuration. You can try to set the permissions to the files and folters of JoomlaWatch to 755, and if this wouldn't help, please contact your system administrator and ask him, why it doesn't work. Who are the "bots" appearing in the statistics? Bots and spiders are special programs run by individuals or companies that visit your website for some purpose. Some of them are "friendly", like googlebot that tries to index the content of your website, and some of them are not.Like the ones, that extract email adresses to send spam to. There are some other spambots, that are filling forms and this way are trying to "promote" some websites. That's why most of the forms use the CAPTCHA (http://en.wikipedia.org/wiki/Captcha) mechanisms. Some of those bots can make many requests to your website, and make it load slower or very occasionally they may cause a server crash (Distributed Denial of Service Attack from many IP adresses). How is it determined who is a "bot"? The principle of JoomlaWatch's differentiation of bots and visitors is simple.. Real visitors when having a normal browser usualy load the images, including the joomlawatch icon. The others are just interested in th HTML source without loading additional images, whsere they can find some email addresses or some other valuable information. It's like I would make a program, that opens the address, parses it, and then sends some emails to the email addresses that it has found. Of course, there are "friendly" bots as well, like the googlebot, that takes care of indexing your website for the google search, or some other. Without these, you won't see your page in search results. I cannot open the .zip archive Sometimes it happens, that when you are downloading a file from the internet, the HTTP connection is timed out. It means, that the download seems to be completed, but only 80% of it is really downloaded. If this happens, try to re-download it again, until you open it succesfully. It's recommended to use some download manager as wget, FlashGet or Mass downloader. The component installation ends with "Cannot find the XML setup..." Free some of your webhosting space. The installation of JoomlaWatch requires at least 20MB. It's because it contains huge ip to location resolving tables. AJAX permission Denied This usualy happens whey you have forgotten the "www." in front of your domain name. It makes the JavaScript think you are trying to access the different domain, and it's restricted because of the security reasons. So, please just try to access your site administration with the domain name that's specified as a "live site" in your configuration.php. (Usualy the domain with the www in in "http://www.yourdomain.com") Why do I see the ads in the JoomlaWatch backend? This is the only way how to keep the component free. Developing the new features costs a lot of time and effort. I hope these ads are not that much intrusive that it would annoy that much people, than paying some money for a single download. If you don't like the ads, please use the version 1.2.5, that comes without them, but with the older features as well. Do you like JoomlaWatch? Please support it at and submit your vote. Thank you :-P See the most active IP addresses. This way you can determine eg. spambots trying to harm your website. Now everything is configured without editing configuration files with user-friendly interface You can block several IP addresses manually All IP you blocked are in a list with number of blocked attempts.

Reporting possible problems of this Joomla stats component Even though most of the bugs are fixed in the latest update, the range of browsers, web servers and their different implementation is very wide, so it's impossible to reproduce the runtime enviroment of every user - you. Before reporting any possible problem, please read the Forum of this website, whether the solution isn't there.If not, please try to include as much information as you can (Browser type and version, PHP version, OS, and the problem why it didn't work). Not just "it doesn't work for me". This kind of report doesn't help anyone. Thank you. OLDER RELEASES: UPDATE (27.01.2008) - added more configurable options into config.php- JOOMLAWATCH_BLANK_ICON to use the blank icon- date and week offsets- JOOMLAWATCH_SERVER_URI_KEY option for cases that it logged only index.php. Now, there is an option to use your own $_SERVER key To upgrade to the new version, please just re-download and re-install. VERSION 1.2.0 Changes and improvements:- improved security- now showing real visitors and bots separately- added right panel with live statistic information:- graph showing weekly unique visitors, page loads and total hits- smaller expandable charts showing daily and all-time count and percentage of popular pages, countries, browsers and operating systems- more configurable parameters- performance improvements using database indices and optimized queries- everything made by AJAX request and partial page updates so you don't have to wait for the whole page refresh UPDATE (03.12.2007): Some improvements - version 1.0.3 - discovered a bug, some PHP configuration are just set to interpret <?php and ignore <? , fixed- config.php with the update interval configuraiton- country code right next to the country flag (for those who don't know country flags)- JoomlaWatch icon now looks better on a dark background - some minor issues fixed (thanks to Wayne Wenquiang)- notice about the latest version in the installation- versioning UPDATE (22.11.2007): Automatic Refresh in IE Some users reported that the administration part did not refresh automatically. I found out that this problem occured only in Internet Explorer. The problem was, that IE did not recognized the http.responseText[i] javascript command, so I replaced it with http.responseText.charAt(i) and succesfully tested it with Internet explorer, firefox and Joomla 1.0.13. Sorry for any inconvenience UPDATE (15.11.2007): Notices Some people reported, that the JoomlaWatch icon was not properly shown, and therefore JoomlaWatch did not work. It was mainly because they had the PHP NOTICES enabled on server by default. This caused the coruption of the gif icon adding PHP text output to icon's binary data. In this fix I suppressed the notices by adding the @ in front of several PHP expressions and corrected some PHP's complains.

We stayed in the IBIS hotel Karlin. When they asked me how would I pay, I said, I would pay with my debit Mastercard. They took it to "authorize me". To my surprise the amount of approx. 300 EUR was taken, I recieved an notification SMS immediatelly.They said they are going to return this at the check-out date. Ok, after a check-out they gave me two reciepts, one for the rollback of the authorization (300 EUR) and second for our room (178 EUR).  Now, five days have passed, and I didn't get my money back ! Why ? .. I went to my bank, they said - It's a problem of a hotel. So I decided to call a hotel manager. They said, as I thought, the problem is in the bank, and it's an usual situation and I should wait and wait and wait until I'll get my money back. But how long ???Is it normal ? 300 EUR were taken immediatelly, so what the hell the return takes such a long time ?How then the clients should be motivated to pay with a card, when such situation happens? I am not desperate about that money, it's about a principle.. My friend said, what would happen when you will travel around europe and everytime you will stay night in different hotel you will pay also the authorization.A friend of mine payed the same way somewhere in France. His money are somewhere "on the way" in the virtual world second week !    http://www.codegravity.com/index.php?option=com_content&id=820 Strange IE problems - I've been experiencing str ... http://www.codegravity.com/index.php?option=com_content&id=819 I've been experiencing strange Internet Explorer 6.0 problems. I'm using firefox, but when I wanted to check my site at internet caffee last saturday, I just couldn't. I just saw the error dialog "Internet Explorer cannot open the Internet site http://www.codegravity.com"..But WHY ??Then there was a blank page with "The page cannot be displayed". DNS problem? - IP resolving worked well !..Today I tried to comment out every javascript code, but without any special result. Now it seems to work better.

If you want to know some of my experiences, just read on.. http://www.codegravity.com/index.php?option=com_content&id=816 Icefaces custom tag with facelets - I've been struggling with ... http://www.codegravity.com/index.php?option=com_content&id=814 I've been struggling with creating my own icefaces tag that I could use everywhere it's needed. There are many tutorials on the internet, BUT.. I couldn't get it work anyway. When I looked at the sourcecode on the webpage, the tag     <ticker:ticker />  was there directly in the HTML sourcecode. This is wrong, because I expected the rendered ouput there.One whole week I tried to solve this problem trying almost everything. But then, finally, I found it.So, what was the problem? When you are using Facelets with your JSF/Icefaces, the TLD (tag library descriptor) files are for nothing. Even if I tried to place them everywhere. You have to create the equivalent of the TLD file for the Facelets - the XML file describing the tag structure. In this case it's ticker.taglib.xml   The tag descriptor for the facelets   There you specify the component's class - Ticker, and it's renderer - TickerRenderer. Now, you don't need the TickerTag as suggested when using JSP in many tutorials around the internet.Also don't forget to tell the JSF to recognize your taglib and place this XML snippet into web.xml (just the first reference to xml, the second is when you want to use also another taglib - eg. the tomahawk components) Put the reference to your tag descriptor into web.xml       <context-param>        <param-name>facelets.LIBRARIES</param-name>        <param-value>            /WEB-INF/ticker.taglib.xml;/WEB-INF/tomahawk.taglib.xml        </param-value>    </context-param>   JSF source with a custom tag Rendered output I wonder why this 'trick' hasn't been described yet in some tutorial. So, I hope you will find this remark useful and it will help you when creating your own JSF components.    http://www.codegravity.com/index.php?option=com_content&id=814 Firefox extensions - useful XUL resources -  I've been reading so ... http://www.codegravity.com/index.php?option=com_content&id=813  I've been reading something about firefox extensions programming.

Skúste však nájs? takú aktivitu ktorá by vám vyhovovala. Plávanie je v zime jednou z mála ke? je vonku škaredo. Aká je však situácia, druhé najvä?šie slovenské mesto ? Neuveríte, no v Košiciach si nezaplávate! Vyzerá to tu tak, Âe 236 093 ?udí (údaj z roku 2001) je tu JEDNA ! Áno - jedna krytá plaváre?. Nešlo by tak ani o to, ako skôr o jej dostupnos?:   Pripadá mi to ako keby plaváre? bola nejaká banka (ako sme to mohli vidie? v istej poslednej reklame) - majú rovnakú pracovnú dobu ako vy :) Poml?ky znamenajú Âe bazén nie je verejnosti k dispozícii. Va?šinou je to kvôli tomu, Âe sú to vrieskajúce deti, ktoré majú tréning v ?ase kedy chcete oddych :) Nerozumiem pre?o by tie tréningy nemohli ma? niekedy cez obed, alebo dokonca ráno, tak ako to bolo napríklad v Poprade na gymnáziu. ?alšej veci ktorej nerozumiem, je to, Âe sa plaváre? zatvára o ôsmej. Âeby tety za okienkom chodili spáva? po ve?erní?ku a plav?íci tie ? Nechcem robi? reklamu, ale pre?o napr. Popradské Aquacity má plavecký bazén bez problémov do 22:00 ? (zdroj: http://www.aquacity.sk/opening.aspx ) Niekto môÂe poveda? - "ve? tam môÂeš by? cez víkend"..Áno, ale cez víkend sa dá ís? relaxova? aj inde mimo mesta, tak skôr ?lovek vyuÂije to. Neostane kvôli plávaniu predsa sedie? doma. Táto situácia sa mi vôbec nepá?i a Košice ako mesto otrasne zaostávajú. Prichádzajú tu nové IT firmy a ostávajú noví ?udia. No Âe by preto spravilo nie?o mesto, tak toho sa asi nedo?káme, Âe? Skúste ís? pláva? ke? sú vo?né 4 dráhy. KaÂdý ide ako buldozér, pomalí plavci, tí ?o sa len ?vachtajú - chaos :). V Anglicku sa mi pá?ilo ako mali bazén riadne rozdelený pod?a toho ?i pláve niekto rýchlo, stredne rýchlo alebo pomaly. Vrámci jednej dráhy plávali dvaja plavci, kaÂdý po pravej strane v smere plávania podobne ako na ceste. U som tento návrh písal aj cez stránku plavaren.info, no asi treba ?aka? ešte 10 rokov :) Som z tejto situácie sklamaný a vlastník hospodári naozaj zle, ve?a ?udí by si aj priplatilo aby malo nejakú kvalitu, ale ke? naozaj nie je záujem nie?o meni? ? Uvítam kaÂdý názor a pomoc v riešení problému ktorý trápi ur?ite nielen m?a ale mnoho ?alších Košia?anov.

Even though it is protected with the captcha image that you have to enter everytime before you submit the form, some spambots somehow broke this protection and kept flooding my comments. This was the reason why, I decided to replace the default captcha mechanism with my own PHP MathGuard Class. Here is a short overview how to apply my patch.  http://www.codegravity.com/index.php?option=com_content&id=809
