Unable to load the requested class - El Forum - 10-02-2009

In my application/libraries/ directory...
I am trying to extend my "MY_Controller" class with a "MY_Auth" class.
The MY_Controller class I have already created works great. But when I create any other classes I continually get this error:
Quote:An Error Was Encountered
Unable to load the requested class: Auth
The steps I am taking:
1) I create the file named MY_Auth.php, save it to 'application/libraries/'
2) Its code:
Code:
class MY_Auth extends Controller{
function __construct(){
parent::__construct();
}
}3) Open the config/autoload.php and change this line to contain my new class:
Code:
$autoload['libraries'] = array('database','auth');Then get the error. I don't understand how to get past this.
Also, why did I not have to add MY_Controller to the $autoload[] array? And it works just fine. I have tried not adding MY_Auth, but then it errors out as well.
Please help.
Thank you.

You have the wrong name MY_Auth should be MY_Controller but the class name you can name it anything you like.
Then you extend it in your new Controllers. When you save it the name would be MY_Controller in the application/libraries folder.
So if you wanted an Auth contoller you would do this:
class Auth extends Controller
Then save it as MY_Controller in the application/libraries folder.
Then when you create a new controller
class New extends Auth

Thanks for the reply InsiteFX.
So you can only create a MY_Controller.php for application/libraries/ ?
No other library files can be created along with it?

No you can create other libraries but you can only have one MY_Controller
But you can have different directories see the CodeIgniter user guide here:

I read through the information contained in the Managing your Applications link. Though didn't see anything relating to this issue.
Must the other files contained in applications/libraries/ also have the "MY_" prefix? (Or whatever it is defined as in config).
It seems I cannot load any classes except what is defined in "MY_Controller.php".
Attempting to load any other class with a different file name continually brings up this error:

Thanks again for your help, InsiteFX.

OK, I think I understand the "MY_" prefix better now. It is only for extending native CI classes.
Other than that, library files do not need the prefix. Correct?
I was trying to (excuse my terminology) "double extend" the Controller.
Theoretically, I was trying to do this: "Auth extends MY_Controller extends Controller".
Was attempting this by creating an Auth.php that extends MY_Controller, while having the MY_Controller.php extend Controller. Then in application/controllers/, create a controller class 'New extends Auth', to gain a level of authentication.

This can be achieved, but you have to let CI know where your Auth base controller is.
The 2 most methods is adding it to MY_Controller or adding an include in MY_Controller:
Code:
// method 1
// file: MY_Controller.php
class MY_Controller extends Controller {}
class Auth extends MY_Controller {}
// method 2
// file: MY_Controller.php
class MY_Controller extends Controller {}
include APPATH . '/libraries/auth.php';
// file: auth.php
class Auth extends MY_Controller {}Once you have this in place you can build controllers like you would expect:
Code:
// admin.php in your controller folder
class Admin extends Auth {}Hope this clears things up.
