Routes, how to handle empty strings? [SOLVED, with hack]

When a user goes to the URI http://localhost/pages/cake-types I want to show the user a list of cake types. However, when the user goes to the URI http://localhost/pages/cake-types/cupcakes it should the appropriate page (a page related to cupcakes).

Hmmm, this is one of those times when you wonder if you're reading the question correctly.

No routes required.

You have a controller, say Cakes, with a method of cake_types. If no cake type is specified, show all cakes, else show the cake type requested.

Sample URIs:

http://www.houseofcakes/cakes/cake_type //shows all cakes
http://www.houseofcakes/cakes/cake_type/cupcakes //shows cupcakes

Code:

class Cakes extends Controller{
    
  function __construct()
  {
    parent::Controller();
  }
  
  function cake_type($type='')
  {
    if($type=='')
    {
      //show all types
    }
    else
    {
      //show $type
    }
  }
  
}

No?

And if you called the cake_type method in the index method, you could also use the URI

http://www.houseofcakes/cakes //shows all cakes because it calls the cake_type method without argument

Code:

<?php

class Cakes extends Controller{
    
  function __construct()
  {
    parent::Controller();
  }
  
  function index()
  {
    $this->cake_type();
  }
  
  function cake_type($type='')
  {
    if($type=='')
    {
      echo 'All!';//show all types
    }
    else
    {
      echo $type;//show $type
    }
  }
  
}
