Custom Controller

Hey there,

I'm having no luck with a custom controller I'm trying to use, I've got two, the first one works 100% but the second one is giving me problems. Here's my setup.

My Working Controller

# /config/config.php

PHP Code:

$config['subclass_prefix'] = 'SH_'; 


# /core/SH_Controller

PHP Code:

class SH_Controller extends CI_Controller  {

  public function __construct()
  {
    parent::__construct();
  }
} 


# Controllers/home.php

PHP Code:

class Home extends SH_Controller {

  function __construct()
  {
    parent::__construct();
  }
} 


And the one that's not working.

# core/SH_Shopping.php

PHP Code:

class SH_Shopping extends CI_Controller  {

  public function __construct()
  {
    parent::__construct();
  }
} 


# controllers/store.php

PHP Code:

class Store extends SH_Shopping {

  function __construct()
  {
    parent::__construct();
  }
} 


I've read everything online about adding __autoload in the config etc but nothing seems to work ... Any idea's ?

Take a look at the core system files in the CodeIgniter.php file you can see how the subclass prefix is used when loading controllers.

Line 237 - 240

if (file_exists(APPPATH.'core/'.$CFG->config['subclass_prefix'].'Controller.php'))
{
require APPPATH.'core/'.$CFG->config['subclass_prefix'].'Controller.php';
}

When you name it other than _Controller the system does not seem to register that, in order to have a Controller that does not end with _Controller you're out of luck. Is there a reason you need to run multiple controller types? Is there a library solution that would work just as well?

I had an issue a while back with just about every method to get CI to load my admin_controller from the core folder. so what i did was at the end of the MY_Controller file i added a require_once statement. 

so if your set on doing it this way two things,

first make your SH_Shopping controller extend SH_Controller. That way any functionality in SH_Controller will be available to your SH_Shopping controller.

then the next step would be to make your SH_Controller class file look like this:

PHP Code:

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

if ( ! class_exists('SH_Shopping'))
{
  require_once APPPATH.'core/SH_Shopping.php';
}

Thank you for that code Hobbes, I think that's exactly what I will do.

Correct me if I'm wrong but should the include not read.

PHP Code:

if ( class_exists('SH_Shopping'))
{
  require_once APPPATH.'core/SH_Shopping.php';
} 


That must have been the most dumpest post I've ever made in my entire life, please ignore

lol no problem. we are all prone to the proverbial blonde moment

This hack is ok but why do you need 2 CORE controllers ?

The "core" folder is to replace or extend an existing CI core class. You exdended the CI_Controller class with SH_Controller, that's ok. But Shopping is not a core class. There's no CI_Shopping class in CodeIgniter. You need to put this file in the "controllers" folder.

Add the code (in core/SH_Shopping.php) to the file /core/SH_Controller.php

It will work fine.
