php - How do I pass a parameter from URL to an admin generated form? -

i have 2 models namely 'client' , 'pet' have admin generated modules each. there one-to-many relationship involved want able create new pet using cid (client id) specified in url (i.e. /pet/new/cid/6)

i disabled cid field in client form parameter url passed default value.

i tried overriding actions.class.php of admin generated module code:

public function executecreate(sfwebrequest $request) {     $this->form = $this->configuration->getform();     $params = $request->getparameter($this->form->getname());     $params["cid"] = $request->getparameter('cid');     $request->setparameter($this->form->getname(), $params);      parent::executecreate($request); } 

it works if replaced

$request->getparameter('cid'); 

with hard-coded int value think problem i'm not able parameter url.

i think might missing on routing configurations i'm new framework i'm not sure do.

you can pass parameter cid in url :
/pet/new?cid=6

and result in action :
$request->getparameter('cid');

the first part of routing (/pet/new) specific doctrineroutecollection
