Getting the posts current category ID
Ok ive tried lots and lots of things, searched extensively here and tried more sql than I care to think of but this is beyond me.
I have posts that are in multiple child categories but i want to display some random posts from the currently active posts child category. So all i need is to retrieve that posts currently active child category ID.
I’ve tried the global $cat but that just returns the parent category and not the currently viewed child category.
Is there anyway to retrieve the current viewed posts child category id ?
