Using Hooks

Hi,

I'm trying to use my own classes with hooks, so on a fresh install of last CI, I've enabled hooks in config file.
Modified hooks.php by adding :

PHP Code:

$hook['pre_system'][] = array(
  'class' => '',
  'function' => 'load_app_controllers',
  'filename' => 'App_controllers.php',
  'filepath' => 'hooks'
); 


Added a file call App_Controllers.php in hooks folder :

PHP Code:

function load_app_controllers()
{
  spl_autoload_register('my_own_controllers');
}
function my_own_controllers($class)
{
  if (strpos($class, 'CI_') !== 0)
  {
    if (is_readable(APPPATH . 'core/' . $class . '.php'))
    {
      require_once(APPPATH . 'core/' . $class . '.php');
    }
  }
} 


Then a file MY_Controller.php in Controllers :

PHP Code:

<?php

class MY_Controller extends CI_Controller
{
  public function __construct()
  {
    parent::__construct;
  }
}

class Admin_Controller extends MY_Controller
{
  function __construct()
  {
    parent::__construct();
    echo 'This is from admin controller';
  }
}

class Public_Controller extends MY_Controller
{
  function __construct()
  {
    parent::__construct();
    echo 'This is from public controller';
  }
} 


And two file in controllers "Admin_Controller.php" :

PHP Code:

<?php

class Admin_Controller extends MY_Controller
{
  function __construct()
  {
    parent::__construct();
    echo 'This is from admin controller';
  }
} 


Public_Controller.php :

PHP Code:

<?php

class Public_Controller extends MY_Controller
{
  function __construct()
  {
    parent::__construct();
    echo 'This is from public controller';
  }
} 


And finally modified Welcome.php :

PHP Code:

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

class Welcome extends Admin_Controller { 


Problem is that I got error :

Code:

Fatal error: Class 'Admin_Controller' not found in /Applications/MAMP/htdocs/hooks/application/controllers/Welcome.php on line 4
A PHP Error was encountered

Severity: Warning

Message: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/hooks/application/controllers/Welcome.php:4)

Someone ?

If you have MY_Controller in the application/core folder you don't need the hook CI will use it be default as long as the it is define in config.php $config['subclass_prefix'] = 'MY_'; (default)

Since you have your Admin and Public controller defined in the MY_Controller file, you don't need these 2 controller files.

A good decision is based on knowledge and not on numbers. - Plato

Code for the MY_Controller:

PHP Code:

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

/**
 * Class Base_Controller
 * 
 * This file should be saved at:
 * ./application/core/MY_Controller.php
 * 
 */
class Base_Controller extends CI_Controller {

    /**
     * Class variables - public, private, protected and static.
     * --------------------------------------------------------------------
     */

    /**
     * @var  array
     */
    protected $data = array();
    
    /**

     */
    public function __construct()
    {
        parent::__construct();

        /**
         * check to see if we want to use the CI profiler.
         * Requries the below in the ./application/config/config.php
         * //$config['profiler'] = TRUE;
         * $config['profiler'] = FALSE;
         */
        $this->output->enable_profiler($this->config->item('profiler'));

        log_message('debug', 'CI: MY_Controller class loaded');
    }

}    // End of Base_Controller Class.

/**
 * Class Admin_Controller
 */
class Admin_Controller extends Base_Controller
{
    /**
     * Class variables - public, private, protected and static.
     * --------------------------------------------------------------------
     */
    
    /**
     *  __construct ()
     * --------------------------------------------------------------------
     *
     * Class    Constructor
     */
    public function __construct()
    {
        parent::__construct();

    }


}    // End of Admin_Controller Class.

/**
 * Class Public_Controller
 */
class Public_Controller extends Base_Controller
{
    /**
     * Class variables - public, private, protected and static.
     * --------------------------------------------------------------------
     */
    
    /**
     *  __construct ()
     * --------------------------------------------------------------------
     *
     * Class    Constructor
     */
    public function __construct()
    {
        parent::__construct();

    }

}    // End of Public_Controller Class.

/**

Sorry as this was my first post and it was moderate, I could not reply earlier, I ended up solving my problem, the MY_Controller was in wrong place  .
Thx for your replies, I've understood how it works now
