codeigniter check for user session in every controller

Question

I have this private session in one of my controllers that checks if a user is logged in:

function _is_logged_in() {

   $user = $this->session->userdat         


        

Answer 1

Just add this on your folder core file ci_controller at function __construct() to check all controller ():

function __construct() 
{
    parent::__construct();
    if(! $user = $this->session->userdata('user_data');)
    {
         return false;
    }
}
