add actions with url parms to isAuthorized() function

[Iluvatar+]

Is it possible to have access controll on url parms. For example i have a CreatePage controller but each created page will have a franchise_id related to it and stored in it's table. I want to be able to allow and deny specific franchises within the CreatedPages controller.

 

i.e:

<?php
if($this->action==Stepone/?fran_id=2){
	if($this->Auth->user('role') == 'user') {
		return true;
	} 
               else   {
      ...
?>
