Need tips about authentication check (cookies) - Rashid - 11-03-2015
What is the most common and robust auth check pattern in CI?
I personally see two ways:
1) insert check routine into a hook-function ('pre_controller' or 'post_controller_constructor' ?) - one for all controllers - nice
2) write it in __construct() directly, but it forces to duplicate code a lot, for each controller. bad..
I tried 1st way but got this:
PHP Code:
$hook['pre_controller'] = function ()
{
$id = $this->input->cookie('user_id'); // ERROR: Undefined property: CI_Hooks::$input
// ...
};
It seems that $this->input is absent in function's scope. Maybe I should create standalone class? or entirely different approach?
Please nudge me in a right direction.

Create a MY_Controller and do your checks in it, then extend all your other controller's from your MY_Controller.

Besides the fact that you want to check a user id from a cookie i think you are on the right path.
Try the following:
in your config/hooks.php
PHP Code:
$hook['pre_controller'][] = array(
"class" => "AppCookieValidator",
"function" => "initialize",
"filename" => "AppCookieValidator.php",
"filepath" => "hooks"
);
and create a File named AppCookieValidator.php in the application/hooks/ directory and do something like this
PHP Code:
class AppCookieValidator
{
private $ci;
public function __construct()
{
$this->ci = &get_instance();
}
public function initialize()
{
$id = $this->ci->input->cookie('user_id');
}
}

Tried it. Should be $hook['post_controller_constructor'] otherwise get_instance() returns NULL.
