CodeIgniter routing issue, advice how to do it

Question

I'm not CI programmer, just trying to learn it. Maybe this is wrong approach, please advice.

my controller(not in sub directory) :

class Users extends CI_Controller {

    function __construct() {
        parent::__construct();
    }

public function index($msg = NULL) {

        $this->load->helper(array('form'));

        $data['msg'] = $msg;

        $this->load->view('user/login' , $data);

    }

   public function process_logout() {
        $this->session->sess_destroy();
        redirect(base_url());
    }

}

And a route for login :

$route['user/login'] = 'users/index';

Problem is when I wanna logout, it shows me 404 because I do not have it in my route :

$route['user/process_logout'] = 'users/process_logout';

and in my view I put <a href="users/process_logout">logout</a>

When I add that, it works, and that is stuppid to add a route for everything. What I'm I doing wrong, please advice.

Thank you

Don't know why you are trying to implement login feature in index() function. However since you said you are learning CI I'm telling something about _remap() function.

Before that. You can try the following routing:

$route['user/:any'] = 'users/$1';
$route['user/login'] = 'users/index';

If you want to take value immediately after controller segment you need to use _remap() function and this function may be solve your routing problem, i mean you don't need to set routing. Lets implement your code controller 'users' using _remap() function.

class Users extends CI_Controller {

    private $sections = array('login', 'logout');

    function __construct() {
        parent::__construct();

    }

   public function _remap($method)
   {
        $section = $this->uri->segment(2);

        if(in_array($section, $this->sections))
            call_user_func_array(array($this, '_'.$section), array());

        else show_404(); // Showing 404 error
   }

   private function _login() 
   {
        $msg = $this->uri->segment(3);

        $this->load->helper(array('form'));
        $data['msg'] = $msg;
        $this->load->view('user/login' , $data);
    }

   public function _logout() {
        $this->session->sess_destroy();
        redirect(base_url());
    }

}
