Question

In my CI system\libraries directory I have a new class named DD_Controller.php. This file looks like this:

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

class DD_Controller extends Controller 
{   
    protected $ddauthentication;


    function __construct()
    {           
        parent::Controller();
        $this->ddauthentication = "Authenticated";
    }
}
?>

My application controller is defined like this:

class Inquiry extends DD_Controller 
{...}

The Inquiry class works fine when I extend Controller, but I get a

Fatal error: Class ‘DD_Controller’ not
found in
C:\development\localhost\applications\inquiry\controllers\inquiry.php
on line 4

When I extend DD_Controller. In the config file I have the prefix defined as such:

$config['subclass_prefix'] = 'DD_';

Any idea of what I’m missing?

TIA

DD_Controller.php should be in /system/application/libraries/

If you’re using the same CI for multiple apps, and you want them all to be able to extends their controllers to your custom one then you can extend the base Controller class in the same file.

In system/libraries/Controller.php below the Controller class:

class Mega_Controller extends Controller {
    function Mega_Controller()
    {
        parent::Controller();
        // anything you want to do in every controller, ye shall perform here.
    }
}

Then you’ll be able to do this in your app controllers:

class Home extends Mega_Controller {
    ....

Since the extended controller class you created will be available. I think this is better then overwriting the base controller, but that would work as well.
