cant delete a record, total n00b here.

[eluser]rotarypot[/eluser]
hola !

i am very very new to ajax/CI, so please be gentle

i am trying to delete a record from my table and also have the nice animation to visually remove the record from the page,of course, i should make the actual record deletion work before moving on to the animation thingie, but im stuck and cant get it to delete records
please help


this makes the "delete" links

Code:

<?= anchor('#', 'borrar', array('class' =>'borrador', 'id'=>$res->img_id));?>

this is my jQuery (in the view file)

Code:

$(document).ready(function() {
    $("a.borrador").click(function (event) {
        event.preventDefault(); // deshabilita el comportamiento de la liga.
  if (confirm('esto borrará la img, de acuerdo? ')){    
        // usuario dijo si a la pregunta.
               var del_id = $(this).attr('id');
               $.post("index.php/moderation/borrar", {item_id : del_id},  function(data){
                      
                       // succcess??
    }); }
});    });

this is my controller (simplified)

Code:

<?php

class Moderation extends Controller {

    function Moderation()
    {
        parent::Controller();

        $this->load->helper('url');
        $this->load->helper('form');
        $this->load->database();    
            
    }
    
    function borrar() {
    
     $this->db->delete('gallery_imgs', array('img_id' => $_POST['item_id']));
    

      
}
    
}
