User authentication using CodeIgniter
- by marcin_koss
I have a problem creating authentication part for my application.
Below is the simplified version of my controllers.
The idea is that the MY_controller checks if session with user data exists.
If it doesn’t, then redirects to the index page where you have to log in.
MY_controller.php
class MY_Controller extends Controller {
function __construct()
{
parent::__construct();
$this->load->helper('url');
$this->load->library('session');
if($this->session->userdata('user') == FALSE) {
redirect('index');
} else {
redirect('search');
}
}
}
order.php - main controller
class Orders extends MY_Controller {
function __construct()
{
parent::__construct();
$this->load->helper('url');
$this->load->library('session');
}
function index()
{
// Here would be the code that validates information input by user.
// If validation is successful, it creates user session.
$this->load->view('header.html', $data); // load header
$this->load->view('index_view', $data); // load body
$this->load->view('footer.html', $data); // load footer
}
function search()
{
//different page
}
what is happening is that the browser is telling me that “The page isn’t redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete.”
It seems like the redirect() is being looped. I looked at a few other examples of user auth and they were build using similar technique.
