   I'm redesigning my blog and I'd like to display a list (or just the latest) post that is assigned to multiple categories.

   I know about the category__and function, but so far as I can tell it requires you to specify which categories your post must belong to (e.g., show posts in categories 2 and 6).

   What'd I'd like to do is show any posts that belong to more than one category, but I can't find anything on how to do this in the codex or the forums.

   Is there a way to use category__and to ask for a list of all posts assigned to multiple categories?

   Is there another function that would do this instead?

   Alternatively, what might be the best way to go about writing a hack to do this?

   p.s. I should mention that I'd like this list to go on the homepage, not a category archive - though a way to do that would be interesting, too.

   Hy,

   same problem here, only I'm looking for solution to show those posts in some category.

   Actually, let say,
   In category 5 I want to show post which belong to category 3 and 5.
   Or I can say...
   show post which belong to CURRENT CATEGORY and CATEGORY 5.

   Thanks for any help in advance.
   Andrija

   See here for full text: http://codex.wordpress.org/Template_Tags/query_posts

   Category Parameters

   Show posts only belonging to certain categories.

   * cat
   * category_name
   * category__and
   * category__in
   * category__not_in

   Show One Category by ID

   Display posts from only one category ID (and any children of that category):

   query_posts('cat=4');

   Show One Category by Name

   Display posts from only one category by name:

   query_posts('category_name=Staff Home');

   Show Several Categories by ID

   Display posts from several specific category IDs:

   query_posts('cat=2,6,17,38');

   Exclude Posts Belonging to Only One Category

   Show all posts except those from a category by prefixing its ID with a '-' (minus) sign.

   query_posts('cat=-3');

   This excludes any post that belongs to category 3.

   Multiple Category Handling

   Display posts that are in multiple categories. This shows posts that are in both categories 2 and 6:

   query_posts(array('category__and' => array(2,6)));

   To display posts from either category 2 OR 6, you could use cat as mentioned above, or by using category__in (note this does not show posts from any children of these categories):

   query_posts(array('category__in' => array(2,6)));

   You can also exclude multiple categories this way:

   query_posts(array('category__not_in' => array(2,6)));

   Thank You VERY VERY MUCH monkeymynd!
   I have looked before that url You suggest me but then I didn't find answer. Now I did!!! :) Thanks once again.

   My questions was,
   How to show 1 post which belong to both:
   CURRENT Category + some other category?

   SOLUTION :
   =============================================================
   1. QUERY in category.php show 1 post which belong to both:
   current category + category 12 (ID).
   =============================================================
   <?php query_posts(array('showposts' => 1, 'category__and' => array($cat,12))); ?>

   <?php while (have_posts()) : the_post(); ?>

   <div class="post">
   bla bla bla ... define how is that post shown.
   </div>

   <?php endwhile; ?>

   =============================================================
   And below that query I have another query->
   =============================================================
   2. QUERY in category.php show all other posts which belong
   to current category as usually.
   =============================================================

   <?php
   $categoryvariable=$cat;
   $queryCAT= 'cat=' . $categoryvariable. '&orderby=date&order=ASC';
   query_posts($queryCAT); ?>
   <?php while (have_posts()) : the_post(); if( $post->ID == $do_not_duplicate ) continue;
   update_post_caches($posts); ?>

   <div class="post">
   bla bla bla ... define how is that post shown.
   </div>

   <?php endwhile; ?>
   =============================================================

   enjoy ;)

   P.S. sorry on my bad English
