A CodeIgniter controller to enable dynamic AJAX access to models from views.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Ajax extends CI_Controller {
function __construct()
* Dynamic AJAX access to models from views.
* In jQuery, can be used by:
* $.post('ajax/MODEL/METHOD', { arg1: val, arg2: val }, function(data) {
* // Do something with returned data
* }, 'json');
function _remap($model, $params = array())
// Method will be first array item; we'll ignore the rest (if any).
$method = array_shift($params);
// Load the model requested. CI will throw a nice error for us if it doesn't exist.
// Call the model and method requested, and pass in any $_POST data that was sent.
$output = call_user_func_array(array($this->$model, $method), $_POST);
// 'echo' rather than 'return', as this is an AJAX controller, and encode as JSON
echo json_encode($output);
