jquery $.post server cpu with controller function

Hi there.

I have just in the last couple of weeks started using codeigniter, and better yet, yesterday I started learning about jquery. I am a complete noob so here goes.

I am having trouble with using jquery $.post to retrieve data via a controller function. I am trying to follow the MVC standards.

Code:

$("a").click(function(show)
                {  
                    var stuff = $(this).text();
                    show.preventDefault();
                    $.post('users/getusertest', { user: stuff },
                        function(output){
                            $('#usage').html(output);
                        });
                });

This works, but it consumes 100% server CPU for at least 5 seconds per click. I have narrowed it down to this -

Code:

$.post('users/getusertest', { user: stuff }

if I create a test.php file for processing the $.post, I don't get cpu problem!

Code:

$.post('test.php', { user: stuff }

TEST.PHP

Code:

<?php

echo "user test ".$_POST['user'];
?>

I am trying to keep the code as clean as possible.


Here is the controller with the getusage function:

Code:

<?php

class Users extends CI_Controller
{
    function __construct() {
        parent::__construct();
        $this->load->model('getdata_model');
        
    }
function index()
    {
        $this->view();
    }
    function view()
    {
        
       ... lots of calls to the model
    }
      
    function getusertest()
    {
        echo "RETURNED ".$_POST['user'];
        
    }
}
?>

The reason I am using jquery to do the post stuff is because I am trying to avoid page refreshes. I am open to criticism, not even sure if this is the best way.

cheers.
