Static Hooks - El Forum - 06-06-2011
[eluser]Clifford James[/eluser]
I just ran into a small problem with my user class and ORM, because I couldn't use a static hook.
Here's my solution, hopefully it saves some time for somebody.
Hooks.php:
Code:
$hook['post_controller_constructor'][] = array(
'class' => 'User',
'function' => 'is_loggedin',
'filename' => 'User.php',
'filepath' => 'models',
'static' => TRUE,
'params' => array(TRUE)
);MY_Hooks.php:
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
