I need the Category_ID in a loop to make conditionnal conditions and the function Category_ID is deprecated. So I have search a lot for the good method. I have found a get_the_category whitch is not working for me...
I'm on WP1.5.2, I just want to obtain the cat ID of the current post, it's possible I'm a little dummy but... I don't succed and Wiki, Codex and forum give opposite informations.
Is there someone who know the truth about it (the contemporary truth) ? And how to make ?
