Question

I’ve written a couple of Controllers that implement an interface, so it has to be loaded before the Controller is loaded. What’s the standard place to early load dependencies in Codeigniter?

Answer 1

Simply add a require_once at the top of the controller that loads the interface. You can’t use the default CodeIgniter autoload as it doesn’t support interfaces. While you could add the require_once lines at the top of ./config/autoload.php, I would suggest adding it in each controller as follows:

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

require_once APPPATH . 'controllers/Interface.php';

class Welcome extends CI_Controller {
  // Do something useful.
}
