php - Router_Route with optional parameters -


i have following route:

        $gridroute = new zend_controller_router_route(         ':module/:controller/list/:order/:dir/:page',         array (             'module' => 'default',             'controller' => 'index',             'order' => '',             'dir' => 'asc',             'page' => 1,             'action' => 'list'         ),         array (             'page' => '\d+'         )     );     $router->addroute('grid', $mainroute->chain($gridroute));

i able add optional parameter 'filter' route. use following url:

http://example.org/default/list/filter/all/lname/asc/1 or http://example.org/default/list/lname/asc/ or http://example.org/default/list/filter/all

either 1 should work. tried place optional parameter in route did not work. ideas?

typically, in zend's router, in php, optional parameter parameter has default value. add 1 filter parameter:

$gridroute = new zend_controller_router_route(     ':module/:controller/list/:order/:dir/:page/:filter',     array (         'module' => 'default',         'controller' => 'index',         'order' => '',         'dir' => 'asc',         'page' => 1,         'action' => 'list',         'filter' => null, // define default filter here     ),     array (         'page' => '\d+'     ) );
