How To Sub Class An Existing Controller

[eluser]TheFuzzy0ne[/eluser]
Welcome to the CodeIgniter forums!

Yes you can, and it's rediculously easy to achieve! Just include the file you want to extend at the top of your controller:

./application/core/MY_Controller.php

Code:

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

class MY_Controller extends CI_Controller {
    /* ... */
}

./application/controllers/PropertyBase.php

Code:

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

class PropertyBase extends MY_Controller {
    /* ... */
}

./application/controllers/PropertyContractor.php

Code:

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

include APPPATH . 'controllers/PropertyBase' . EXT; // Ta-da!

class PropertyContractor extends PropertyBase {
    /* ... */
}

Hope this helps.
