Hi,

this is an interesting situation because if the menu item links directly to a Zoo category/instance, then the URL itself does not contain the application or category id. Therefore we have to get that info from the Menu system.

This technique will work as long as the category id or application id are not somehow set in the URL. That may be able to happen if there are links to a different application while inside a certain menu item, but I don't know if that happens or not.

In this example I will not show how to detect a different category id in the URL - I will assume that you have followed a menu item to a particular Zoo application.

if ( $option == "com_zoo" ) {
  $menu =& JSite::getMenu();
  $params =& $menu->getParams( $Itemid );
  $appid = $params->get("application");
  if ($appid == 2) return XXX;
  // replace XXX with module id of the module you want to display in Zoo application #2.
}

Hope that helps,
Stephen
