this gets me the posts of the day.
$today = getdate();
query_posts(‘year=’ .$today[“year”] .’&monthnum=’ .$today[“mon”] .’&day=’ .$today[“mday”] );
cats would be 17,18,19,20
My workaround for now was to duplicate the ‘show post’ code 4 times (yeah, kludge) by appending the &cat=17 to each query.
thanks folks!
