[eluser]InsiteFX[/eluser]
application/config/routes.php

Code:

//                    dir/controller/method
$route['login']    = "admin/admin/login";
$route['logout']   = "admin/admin/logout";
$route['register'] = "admin/admin/register";

controllers
  -- admin
  ---- admin.php - extended from Admin_Controller, login is the admin/method which will display the view file.
  ---- users.php - extended from Admin_Controller, for managing users

Code:

// these go into application/core
// NOTE: The class name doe's not have to be MY_Controller but the file has to be saved as MY_Controller.php

class MY_Controller extends CI_Controller {}

class Admin_Controller extends MY_Controller {}

class Public_Controller extends MY_Controller {}

// these go into application/controllers/admin - and would be used for a dashboard and managing users.
class Admin extends Admin_Controller {}
class Users extends Admin_Controller {}

// rest would be application/controlers for Public Controllers
class Main extends Public_Controller {}

Code:

// add this to the bottom of - application/config/config.php
