I have user groups related to a product and want to retieve only the user groups related to that product (instead of all of the related content objects.) So far I can retieve all of the user groups in the system...
$userGroupClass =& eZContentClass::fetchByIdentifier('user_group'); $conditions = array('contentclass_id' => $userGroupClass->attribute('id')); $groupObjects =& eZContentObject::fetchList(true, $conditions);
...and I know how to get all of the objects related to the product...
$productObject =& eZContentObject->fetch($myProductId); $relatedObjects =& $productObject->relatedContentObjectArray();
...but I don't know how to get only the user groups related to the product. Is there an intuitive way to do this, or will I have to take one of the above approaches and loop over the results to pick out the objects I want?

I'd say just loop the related-objects array and create a new array and fill it with the object you want:
(pseudo code) $myFilteredRelatedObject=array(); foreach($relatedObjects as $related) { if($related->attribute('class_identifier')=='my_class_id') { $myFilteredRelatedObject[]=$related; } }//$myFilteredRelatedObject contains the filtered objects.
off course this is pseudo code, but something like this should work (and yes.. I know that your approch is 'cleaner'.. but don't have any ez code here.. so can't check the ez classes.. that's why my answer is probably incomplete).
Good luck!Clemens
