Best way to have multiple parent controllers

[eluser]opel[/eluser]
Ok thanks everyone for their help, for anyone that stumbles across this here is my all my code to get multiple controllers.

At the end of config.php

Code:

/*
|--------------------------------------------------------------------------
| AUTOLOAD CONTROLLERS
|--------------------------------------------------------------------------
|
*/

function __autoload($class)
{
    if(strstr($class,'_Controller'))
    {
        include_once(APPPATH . 'libraries/' . $class . EXT);
    }
}

In libraries/MY_Controller.php (Variables can be passed to all extended controllers)

Code:

class MY_Controller extends Controller
{
    
    function MY_Controller()
    {
        parent::Controller();
        }
}

Code:

<?php  if (!defined('BASEPATH')) exit('No direct script access allowed');

class Base_controller extends Controller
{

    public $navigation = NULL;
    public $footer = NULL;

    function Base_controller()
    {
        parent::Controller();
        $this->navigation();
        $this->footercopy();
    }


    
        function navigation()
        {
            $this->navigation['navigation'] = array("Home", "Test", "contact");
            $this->data['frontend_navigation'] = $this->load->view ('common/frontend_navigation', $this->navigation, TRUE);
        }
    
    
        function footercopy()
        {
            $this->data['footer'] = '© '.date('Y').' '.$this->config->item('project');
        }
    
}
