Hey,
I'm having a crazy problem with these CI sessions. Although I love using CI, the sessions can really grind my gears!
I have an authentication script that will log in and user and direct them to a profile page... happy days. But if I click on a link in the page or reload it for what ever reason I get fired back to the login page again. It's almost like CI uses the session once then just discards the fact that it was set at login.
Have a look at this if you get a sec...
LOGIN CONTROLLER
Code:
<?php
class Login extends Controller {
function Login()
{
parent::Controller();
}
function index()
{
//~~~
$data['title'] = "";
$this->load->view('template/header', $data);
//~~~
// SET VALIDATION RULES
$this->validation->set_rules('user_name', 'username', 'required');
$this->validation->set_rules('user_pass', 'password', 'required');
$this->validation->set_error_delimiters('<em>','</em>');
// has the form been submitted and with valid form info (not empty values)
if($this->input->post('login'))
{
if($this->validation->run())
{
$user_name = $this->input->post('user_name');
$user_pass = $this->input->post('user_pass');
$row_return = $this->user_model->check_valid_user($user_name, md5($user_pass));
if($row_return > 0)
{
// user has been logged in
$this->session->set_userdata('logged_in', TRUE); // SET SESSION IF LOGIN TRUE
redirect('profile/index/');
}
else
{
$this->session->set_flashdata('message', 'Incorrect password.');
redirect('login/index/'); // IF FALSE FIRE BACK TO LOGIN
}
}
else
{
$this->session->set_flashdata('message', 'A user does not exist for the username specified.');
redirect('login/index/');
}
}
$this->load->view('content/login/index');
//~~~
$this->load->view('template/footer', $data);
//~~~
}
}
?>
PROFILE CONTROLLER: Constructor
Code:
class Profile extends Controller {
function Profile()
{
parent::Controller();
// Check if user is logged in
if( ! $this->session->userdata('logged_in')){ // CHECK IF USER IS LOGGED IN (function is a helper)
redirect('login/index/');
}
}
HELPER
Code:
// Get CodeIgniter Object
$CI =& get_instance();
// Session variable to check if user is logged in
$user_session_var = 'logged_in';
if( ! $CI->session->userdata($user_session_var))
{
// user is not logged in
return 0;
}
else
{
// User logged in
return 1;
}
}
