authentication with post_controller_constructor hook

[eluser]Unknown[/eluser]
i try to authenticate a user after controller request, but before the method is called (post_controller_constructor).

however, my browser is telling me the request will get in an infinite loop, so i can't output anything nor debug anything.

in codeingiter.php, here the hook is called

Code:

$EXT->_call_hook('post_controller_constructor');

my hook:

Code:

class Auth {
    
    private $CI;
    
        function __construct(){
            $this->CI =& get_instance();
        }
    
    
        function authenticate(){
                
            $this->CI->session->set_userdata(array('hook' => $_SERVER['php_self']));    
            
            if(!$this->CI->session->userdata("logged_in")) {
                        
                redirect('user/login', 'location');
            }            
        }    
}

Code:

class User extends CI_Controller {

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

public function login(){
  
  $this->load->view('pages/login');
  $arr['un'] = $this->input->post('naam');
  $arr['pw'] = $this->input->post('paswoord');
  
  $this->session->set_userdata(array('logged_in' => $arr));
  
  redirect($this->session->userdata('hook'), 'location');
}
}

HOW SHOULD I NAVIGATE TO GET OUT OF THE HOOK AND PROCEED WITH THE REQUESTED CONTROLLER AND METHOD, THANKS ALOT FOR REPLY !!!!!

The problem is your hook is also firing on the login page.

- Load homepage. Hook fires. NOT logged in. Send to login page.
- Load login page. Hook fires. NOT logged in. Send to login page.
- Load login page. Hook fires. NOT logged in. Send to login page.
- And so on...

Your hook needs to check if it's on the login page or not, so it doesn't continually redirect to itself.
