how to make optional parametres in zendframework URL - zend-framework

Question

I am new to Zend, but very very keen to learn. This is really just a quick question on routing in Zend Framework.
I understand the basic of it but I am still confused about how I can create some optional parameters at the end of my URL. For example, I have the following default page URL:
examplesite.com/accounts/enquiry
I now want to add two additional parameters to it i.e:
userid= 6
location= 12
So, the eventual URL should look like:
examplesite.com/accounts/enquiry/6/12
but
examplesite.com/accounts/enquiry
Will get you to the same page.
I am not clear. How do it do this? I mean, this is not a bespoke URL. so, I don't need to create a custom route. It basically just the last two parameters that need to be added to the page.
How do I do this?

Answer 1

First 2 parameters are controller and action name, the named params.
Here you are:
examplesite.com/accounts/enquiry/userid/6/location/12
or you can define your own route like this:
$route = new Zend_Controller_Router_Route('accounts/enquiry/:userid/:location);
and then add it to router:
$router->addRoute('accounts', $route);

Answer 2

You could add a custom route inside your Bootstrap.php, e.g. (untested):
protected function _initRoutes()
{
[...]
$frontController = Zend_Controller_Front::getInstance();
$router = $frontController->getRouter();
$accounts = new Zend_Controller_Router_Route(
'accounts/enquiry/:userid/:location',
array(
'userid' => '[0-9]{2}',
'location' => '[0-9]{2}',
'controller' => 'accounts',
'action' => 'enquiry',
)
);
$router->addRoute('accounts', $accounts);
[...]
}
