Question

I use to set the session in my login controller is like this

$this->session->set_userdata('logged_in', $session_data);

I used a code for checking session in CodeIgniter for all the controllers

if(!$this->session->userdata['logged_in'])
{
    redirect("xxx");
} 
else {          
}

but this code works fine when I working on the local server but while I uploading it to live server It doesn't work. please help...

Answer 1

You need load session before you use it

 $this->load->library('session');

Dont check session in this way

   if($this->session->userdata['logged_in']!='')
    {
        redirect("xxx");
    } 
    else {          
    }
