is_logged_in检查每一页

Question

I am using CodeIgniter. I have a controller named abc and i has functions named index,a,bandc.

www.example.com/abc/

I want that user can only access the area he is logged in.

www.example.com/abc/                    //if loggged in else back to homepage

or

 www.example.com/abc/a/                    //if loggged in else back to homepage

Now to check login. I use:

if($this->auth->is_logged_in()) { .. } else { redirect('/'); }

on every function individually.

Is there any other way to do so ??

Answer 1

I think you can do this by overriding the constructor and call your function in it.

<?php
class Blog extends CI_Controller {

       public function __construct()
       {
            parent::__construct();
            // check login
       }
}
?>
