CI 2 - extending the controller problems

[eluser]richzilla[/eluser]
hi all,
ive poked around the user guide and the forums for an answer to this but i cant seem to find it. Im trying to extend the default controller class in CI 2:

So far, i have in application controllers:

Code:

<?php

/**
* Controller for app home page
*/


class Home extends MY_Controller {

    function __construct()
    {
        parent::MY_Controller();    
    }
    
    function index()
    {
        $this->load->view('memo_home.php');
    }
}

/* End of file welcome.php */
/* Location: ./application/controllers/home.php *

and in application/core in a file call MY_Controller.php:

Code:

<?php

class MY_Controller extends Controller{
    
    function __construct()
    {
        parent::Controller();
        echo "Parent has been called";
    }
    
}

?>

yet when i run the system i get an error:

Code:

Class 'MY_Controller' not found

ive checked my config file and the prefix is set to "MY_" and all of the file names are correct. Can anybody help me out?

hi ricardino,

try changing the parent constructor in your controller:

Code:

class Home extends MY_Controller {

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

Code:

// this should be in application/controllers
class Home extends MY_Controller {

    function __construct()
    {
        parent::__construct();    
    }
    
    function index()
    {
        $this->load->view('memo_home.php');
    }
}

Code:

// this should be in application/core
class Home extends MY_Controller {

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

    }

}

If this will not work check to make sure that your default controller
is Home and that you have the view file named memo_home.php.

I just tested this on my system and it works fine!

I am a bit confused with your answer. In the above sample, the first controller should be located in the application/controller, and the other is in application/core, but the two controllers are the same :question: :long:

[eluser]InsiteFX[/eluser]
The two controllers are not the same the MY_Controller is extending the core CI_Controller
so it has to go into application/core !

If the Class you are extending is in the system/core then it goes in application/core
If the Class you are extending is in the system/libraries then it goes in application/libraries

Also you need this or the MY_Controller will not load from application/core
Autoload by Phil

Code:

/*

| Nothing to do with config/autoload.php, this allows PHP autoload to work

|
| If using HMVC you do not need this! HMVC will SPL_Autoload.
|
| Place this code at the bottom of your application/config/config.php file.
*/
function __autoload($class)
{
    if (strpos($class, 'CI_') !== 0)
    {
        if (file_exists($file = APPPATH . 'core/' . $class . EXT))
        {
            include $file;
        }
        elseif (file_exists($file = APPPATH . 'libraries/' . $class . EXT))
        {
            include $file;
        }
    }
}

yes then it should be

// this should be in application/core

Code:

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

// this should be in application/controllers

Code:

class Home extends MY_Controller {

    function __construct()
    {
        parent::__construct();    
    }
    
    function index()
    {
        $this->load->view('memo_home.php');
    }
}
