Question

I'm trying to implement basic section that only a logged-in user can access. I overrided CI_Controller, as follow:

//file created in application/core/MY_Controller.php
class Auth_Controller extends CI_Controller {

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

        $this->load->library('session');

        if ($this->session->userdata('user_logged') !== null){
            redirect(base_url() . 'dashboard');
            die();
        } else {
            redirect(base_url() . 'auth/login');
            die();
        }
    }

And then I extend from Auth_Controller all the other controllers that are only available for the logged-in user, as follow:

class Dashboard extends Auth_Controller
{
    public function __construct()
    {
        parent::__construct();
    }

    public function index()
    {
        $this->load->view('dashboardView');
    }
}

But after the login is successful, it doesn't redirect to dashboardView.

Anyone knows what is really happening?

Answer 1

You are redirecting infinitely to the Dashboard controller in this part of the code:

if ($this->session->userdata('user_logged') !== null){
    redirect(base_url() . 'dashboard');
    die();
}

Use this instead (redirect to the login form if the user is not logged in):

class Auth_controller extends CI_Controller {

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

        $this->load->library('session');

        // If the user is not logged in
        if ($this->session->userdata('user_logged') === null){
            // Redirect to http://yoursite/auth/login
            // No need for the base_url function, redirect does it for you
            redirect('auth/login'); 
            // You don't have to exit/die, redirect() already does that
        }
    }
}
