joomla component development with Ajax queries

Question

I have a PHP script used for AJAX queries, but I want them to be able to operate under the umbrella of Joomla\'s (2.5) framework so I can have session id\'s, user id\'s etc

You don't need to create any custom files and add them into Joomla script. You just need a controller to serve ajax request. You don't even need a view (one way).

Your ajax call should be like these:

$(function () {
 $.ajax({                                     
   url: 'index.php?option=com_&no_html=1task=.',  //not_html = 1 is important since joomla always renders it's default layout with menus and everything else, but we want the raw json output            
   dataType: 'json' //data format     
   ...
 });
}); 

And your controller:

    /*
    * @file admin/controller/.php
    */

class Controller extends JController
{

        public function ()
        {

         //do something
         $respnse['message'] = 'Your message for the view';
         die(json_encode($reponse));
        }
    }

...

This is just one of the examples of how it's could be done.
