login check for every page

Hello,

The most simple solution is extends your controller.

I use this solution, you must create MY_Controller in folder application/core

<?php

class MY_Controller extends CI_Controller {

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

if(!isset($this->session->userdata['id'])){
redirect('/login');
}
}
}

Now all controllers that you want "protect" must be extend this controller:

class Welcome extends MY_Controller { ..... }
