Codeignite - Why doesn’t my route work?

Question

I have the following route in Routes.php:

$route['xxxxx/(:any)'] = 'Order/index/$1';

And the following index in the Order controller:

public function index(){
    switch( $this->uri->segment(2)){
      case $this->step2:
        $this->motivation();
      break;
      case $this->step3:
        $this->about();
      break;
      case $this->status:
        $this->status();
      break;
      case 'post':
        $this->post();
      break;
      case 'teste':
        $this->teste();
      break;
      default:
        $this->register();
      break;
    }
  }

But when I try to enter this route by typing localhost/xxxxx for example, it returns me error 404 Page Not Found.

If you want an optional parameter you must then create two route settings, the Framework has no other form (is limited in that respect), then do:

Example:

$route['xxxxx'] = 'Order/index';
$route['xxxxx/(:any)'] = 'Order/index/$1';

_{Reference: URI Routing}

Also worth remembering for this to work smoothly the parameter that is optional must have some default value, example:

class Order extends CI_Controller
{
    public function index($id = null)
    {
        //code
    }
}

in the example case the two routes work for this method!
