   Hi all, I wondered if anyone can shed some light on a small issue I'm having.

   I've got an events page (which just loads posts in 3 different events categories).

   I'm using some conditional statements to control some small graphics that display based on what type of event it is. My questions is, can I use 'in_category' to do something only if the particular post is in 2 categories?

   For example:

   <?php
   	if ( in_category( 'new events' AND 'old events' )) {?>

   So if the post is in the 'New Events' AND 'Old Events' cats, then do something...

   Any thoughts most appreciated!

   <?php
   	if ( in_category( 'new events' ) && in_category( 'old events' ) ) {

   ?>

   Hi and many thanks,

   I've realised that maybe I'm approaching this incorrectly but not quite sure! This is a rough of what I have, not quite working. I presumed that if I could stipulate the style for posts that were in 2 categories, then it would over-ride the style for posts in single cats - this doesn't seem to be the case.

   Might have a re-think!

   might be a problem with the understanding the if/elseif/else structure:

   even if the post is in both categories, the first if statement will be true and the else (with the &&) will not get checked.

   try:

   depending on the location of that code, you also might need to use the absolute paths to the images

   As it happened I finally didn't need to combine styles but thanks for your help! I have another question if anyone has a spare moment!

   I want to give posts different colours depending on which category they are in. I've tried this:

   But I get an error (site doesn't load at all). My php is not good so I'm probably doing something silly here? :-)

   remove line 4, 11, and 18; and change (line 23) the <?php endif; ?> to <?php } ?>

   Funnily enough I had tried that earlier this morning but I get the same page error. Here's my entire page, just in case there is something I missed & if you have time.. many thanks again.
