Hooks in Codeigniter

How can I call a hook for only a few controllers instead of all controllers in CodeIgniter?

E.g.: I want to run the hook for only the admin section. How can I achieve this?

First you will Enable Hooks in config/config.php File

$config['enable_hooks'] = TRUE;

Than Open config/hooks.php File

Than Define Hooks

$hook['post_controller_constructor']  = array(  
    'class'     => 'Post_controller_constructor',      // Class Name
   'function'  => 'check_status',     // Function Name
   'filename'  => 'Post_controller_constructor',   // File Name in Hook Folder
   'filepath'  => 'hooks'       // Controller Path
);

Than create hooks file in Hooks Folder Like hooks/hooks.php open File

Here, In the hook which you wish to run selectively, you can access the ci superobject using $this->ci =& get_instance();. This acts as a pointer which can be used to access the CodeIgniter router to determine the class using $class = $this->ci->router->fetch_class();. You can then check if $class matches a certain value. This would give you:

<?php class Post_controller_constructor {
    var $ci;

    function __construct() {

    }

    function check_status()
    {
        $this->ci =& get_instance();
        $class = $this->ci->router->fetch_class();
        if($class === 'admin') {
            // Hook procedures
        }
    }
}

/* End of file post_controller_constructor.php */
/* Location: ./application/hooks/post_controller_constructor.php */

You can simply do it by checking url of your application in your hook:

$hook = false;
if(strpos($_SERVER['REQUEST_URI'],"admin/"))
$hook = true;
if($hook) {
// do some hook stuff
}
