Zend Framework: How to get default param?

How do I get the 'default' param if not specified?

Consider the following:

http://localhost/controller/action/id/123

In my controller, I can get the value of 'id' using

$request = $this->getRequest();
$id = $request->getParam('id');

If the URL is

http://localhost/controller/action/456

how do I get the value of 456? What is the 'param' name?

From stackoverflow

• By default ZF URL have to follow pattern:

  /controller/action/param1Name/param1Val/param2Name/param2Val ...
  

  You should use router. For example in bootstrap.php:

  $frontController = Zend_Controller_Front::getInstance(); 
  //^^^this line should be already there
  
  $router = $frontController->getRouter();
  $route = new Zend_Controller_Router_Route(
      'yourController/yourAction/:id',
      array(
          'id'       => 1, //default value
          'controller' => 'yourController',
          'action'     => 'yourAction'
      ),
      array('id' => '\d+')
  );
  $router->addRoute('yourController', $route);
  

  uuɐɯǝʃǝs : Where exactly should I add this router? In the doc says in Controller. Is it controllers/myController.php? or in bootstrap.php file? TQ!

  vartec : it's referring to frontend controller

  uuɐɯǝʃǝs : Thank you. Just to share that I need to put all this before dispatching the front controller. // Dispatch the request using the front controller. $frontController->dispatch ();

• try to add this route to router:

  $route = new Zend_Controller_Router_Route_Regex(
      'my_controller/my_action/(\d+)',
      array(
          'controller' => 'my_controller',
          'action'     => 'my_action'
      )
  );
  
  $router->addRoute('my_route', $route);
  

  uuɐɯǝʃǝs : Where exactly should I add this router? In the doc says in Controller. Is it controllers/myController.php?

  David Caunt : Vartec's route is more efficient and better in this case

• Just want to share.

  The above router setting must be used with the $frontController.

  And be sure put it before the controller dispatches.

  <..above router code goes here...>
  
  // Dispatch the request using the front controller. 
  $frontController->dispatch ();
  

  Hope don't waste time like myself. ;-)

  vartec : Of course. That's why I've suggested putting that in bootstrap.php, which is called before dispatching.
