Basically using xajax “You can directly call php functions from your javascript code”

Xajax will do the rest. 

For example, if you are going to write a javascript function Capitalize which captilaze your textbox content when you press a button.

Here is the pure html/javascript code for that:

=============================================

<script>

function Capitalize()

{

      var t = document.getElementById(’cap’).value;

      document.getElementById(’update’).innerHTML = t.toUpperCase() ;

}

</script>

<input type=”text” id=”cap” name=”cap” />

<input type=”button” id=”capbutton” value=”Capitalize” onclick=”Capitalize()” />

<div id=”update”></div>

==============================================

Now see the difference when we use xajax, we can write this Capitalize function in php code and can call from javascript.

function Capitalize($value)

{

    $objResponse = new xajaxResponse();

    $objResponse->assign(”update”,”innerHTML”,strtoupper($value));

    return $objResponse;

}

and you can call from your button’s onclick function:

 onclick=”xajax_Capitalize(document.getElementById(’cap’).value)” 

Here the same functionality we moved from client to server. Thus the point is you can simply call all the functions you written in php (Server Side) from javascript code via onClick, onMouseOver or window.onLoad etc.

You can get the full source code of Capitalize example here:

Start jquery for manipulating html file and execute javascript just like sql queries.

Simply pointer the dom object with a $  and manipulate with different built in function.

For example 

$(”p.neat”).addClass(”ohmy”).show(”slow”);

Don’t need to write javascript inside each node. It is like prototyping. Insted of adding an onClick=”function()” inside the node, jquery define the onclick function from the top level. Your html code will be clean and tidy. If CSS removes all the styling bits, Jquery removes all the javascript bits from html.

You can remap every default action from an html object.

For example normally when you click a link  (<a> tag) it navigate you through the href value. But if you add the jquery code as below:

$(document).ready(function(){
   $("a").click(function(event){
     alert("Thanks for clicking!");
   });
 })

It adds a thanks alert for every click in links.

and if you add :

event.preventDefault();
It prevents the default action also.
You can go to JQuery homepage: http://jquery.com/
and can learn more about JQuery.
The intention of this post was not an explaination about jquery, but some addition website which develops addons based on jquery.
Those are:
http://jqueryui.com/

jquerystyle.com/

Comment me if you know any other jquery websites.

I have developed more than 7 web projects using Symfony framework. Mobshare.in, Amvizone.com, Campaignmanger.in , Movieonline.in etc are some of the websites. But for the past 5 months my developement is in Codeigniter. It is very very lighter than Symfony and has almost all the features of Symfony. Both are MVC framework. But symfony has 4 layer while the latter has only two. Symfony uses modules (extra layer) for Controllers. But Codeigniter eleminates  that layer. It is similer to Ruby on Rails. 

Symfony uses naming convention to map controller and view. For example controller index need indexSuccess.php file as view or indexError.php as error. But in Codeigniter, we have to specify the view manually from the controller

$this->load->view(’myview.php’); 

Symfony has command line tool to develop all the model classes. One thing you have to do is specify the scheme.yml file. But in Codeigniter, you have to make model classes from the scratch. However a lot of database operation libraries are available with it to make the coding life easier. Since we have to load each libraries manually, Codeigniter gaurantee the speed of execution. (Autoloading option is there, but in most of the case we can eliminate unwanted libraries from autoloading - just like execute on the fly)

There is no built in ajax and javascript function in codeigniter. But you can add it as plugin. Like Symfony it also has cache management, logs, testing, helpers, url rules, documentator, scaffolding etc

Codeigniter has a simple folder hierachy that everybody can understand and very less learning curve than Symfony. 

Go through this link if you wanna know about all the features of codeigniter : http://codeigniter.com/user_guide/toc.html

I found another interesting comparison of these two in : http://www.devtrench.com/codeigniter-vs-symfony/

If you are a programmer, you  might experience on saving your different ftp , email , website credintals (usernames and passwords) . Someone uses google documents for saving passwords. Some use email itself as a password storing medium. To be more secured, you have to save your passwords in you local machine rather than putting them into any other 3rd party online medium.

Truecrypt is an open source software for saving secured data (Folders and files). It is available for most of the operating systems (Windows, Linux, Mac etc). The advantage of TrueCrypt is, it creates a seperate partition or storage device as a normal USB memory stick. When you mount the partition it asks for a secured password. You can save your personal and secret files inside this partition. You can creates more than on partition using this software. So you can seperate your data files if you needed.

Here is the website url: http://www.truecrypt.org/

It also provides two level security. It adds a hidden file inside another secured file, so that when an adversary forces you to reveal your password, or forces you to open the secured folder, there is no chance for them to view the hidden encrypted file.
