php - Codeigniter show controller if session exists -


i'm new codeigniter , learn it.

i got 2 controllers, 1st 1 called main , responds user registration / login second 1 called todo , shows todo list.

now if access localhost/list website opens page, write session logic test if user logged in?

my controller todo

defined('basepath') or exit('no direct script access allowed');  class lists extends ci_controller {  public function index() {     $this->load->view('lists');} }

how display using session:

if($this->session->userdata('is_logged_in') == 1)

or have put session logic before each function?

you put session $this->session->userdata('is_logged_in') condition in __construct()

like : 

<?php class lists extends ci_controller {      public function __construct() {         parent::__construct();         if($this->session->userdata('is_logged_in') != 1) {              //redirect code here         }     }      public function index() {         $this->load->view('lists');}     } }
