   I´m using two loops on a page to display posts from two different categories. Above each is the title of the category, which I only want to display if there actually is posts in the category.

   Putting the title inside the loop just results in it getting repeated for each post (of course...).

   I need a simple if statement or something to only display the heading if there is posts in that category. Does anyone know what code I need?

   Most basic loop you can have.
   http://codex.wordpress.org/The_Loop#Using_The_Loop

   <?php
   $postargs=array(
   'showposts' => 4,
   'cat' => 3
   );
   
   $category_box = new WP_Query($postargs);
   if ($category_box->have_posts() ) : while ($category_box->have_posts()) :
   $category_box->the_post();
   ?>
   ... your code to display your posts ...
   
   <?php endwhile; else: ?>
   <p><?php _e('Sorry, no posts matched your criteria.'); ?></p>
   <?php endif; ?>

   If you need to because of using two loops, you can reset the query to stop conflicts. This rarely happens, but just in case, call this after the first loop.

   wp_reset_query();

   Hope this points you in the right direction.

   Hmm does this really lead me in the right direction? I have no problem displaying the posts I want to and from the category I want to.

   My page looks like this:

   Single post
   __________
   Category X title
   Thumbnails from category X
   ------
   Category Y title
   Thumbnails from category Y

   I cant have the title on Category X & Y in the loop because then it gets repeated for every post doesnt it?

   I need a simple if statement or something to only display the heading if there is posts in that category.

   most loops have this:

   if( have_posts() )

   if you paste the full code of your template into a http://pastebin.com/ and post the link to it here, then someone might be able to make a suggestion on how to include this conditional statement.

   Here is the code. Its two near identical loops where only the category is different. You can see there is a div with the name on the category above each loop. I put it outside the loop because if I put it first in the loop, it would repeat the category title for each post.

   My problem is that I dont want the category name there if there are no posts in that category.

   Thanks for helping.

   these lines occur twice:

   if( $my_query->have_posts() ) {
         while ($my_query->have_posts()) : $my_query->the_post(); ?>

   and here is the spot where you could add the category name:

   if( $my_query->have_posts() ) {
   /*HERE CATEGORY TITLE CODE*/
         while ($my_query->have_posts()) : $my_query->the_post(); ?>

   make sure to close and open the php tags accordingly if you enter html code.

   Thanks! I got it to work. It makes sense when I see it but I´m not familiar enough with wordpress and php to always figure it out by myself.

   Looks like this now:
   

   ...if( $my_query->have_posts() ) { ?>
   
       	<div class="grid_24">Portfolio</div>
   
       <?php  while ($my_query->have_posts()) : $my_query->the_post(); ?>

   Issue resolved! :)
