Question

I have a logout controller in codeigniter :

<?php

class Logout extends MY_Controller {

    function index()
    {

        $this->session->sess_destroy();
        redirect('index.php');
    }
}

This logs me out but when i call another controller after logging, like “/site/addnewpost”,
this just logs me in again, as if the sassion had not been destroyed previously. Why is this happening?

Follow ALex’s suggestion, but using CI code:). What I mean, try unsetting each session data individually. I read once about an issue in version 2.0.3 I think, but I don’t remember now and I don’t have time to search for the reference. It’s in their forum, though, and the suggestion was the same: unset each session element one by one.

$this->session->unset_userdata('data_one');
$this->session->unset_userdata('data_two');
$this->session->unset_userdata('data_three');
$this->session->unset_userdata('data_one');
$this->session->sess_destroy();
redirect('home','refresh');  // <!-- note that
//you should specify the controller(/method) name here

You need to redirect because CI’s session are just cookies, not the native php session array.

Another thing…make sure the fault isn’t in your login methods, which logs you in no matter if you succesfully logout or not!
