   Hi,

   I'm trying to make a theme which shows an overview of child categories with title, link and description when entering a category archive. However, I only want to show child categories one level below the current category, and not the children of child categories. How do I do that?

   I've tried the following:

   $childcategories = get_categories('child_of=' . $cat . '&hide_empty=1');
   foreach ($childcategories as $childcategory) {
     if (in_category($childcategory)) {
       echo '<li><h2><a href="';
       bloginfo('url');
       echo '/category/'.$cat_id->category_nicename.'/'.$childcategory->category_nicename.'">';
       echo $childcategory->cat_name . '</a></h2>';
       echo '<p>'.$childcategory->category_description.'</p>';
       echo '<p>'.$childcategory->cat_ID.'</p>';
       echo '</li>';
     }
   }

   ... which seems to work perfectly in MAMP for mac but fails in XAMPP for win as well as on my debian server.

   What am I doing wrong? Can anybody help?

   Thanks in advance.

   See if the depth=n argument works. If works for wp_list_categories so guessing it might work for get_categories.

   Thanks for the tip, however it didn't work.

   mthomps found the solution: http://wordpress.org/support/topic/223988?replies=9#post-1054625

   I ended up with this piece of code, which works as intended:

   <?php
   global $ancestor;
   $childcats = get_categories('child_of=' . $cat . '&hide_empty=1');
   foreach ($childcats as $childcat) {
     if (cat_is_ancestor_of($ancestor, $childcat->cat_ID) == false){
       echo '<li><h2><a href="'.get_category_link($childcat->cat_ID).'">';
       echo $childcat->cat_name . '</a></h2>';
       echo '<p>'.$childcat->category_description.'</p>';
       echo '</li>';
       $ancestor = $childcat->cat_ID;
     }
   }
   ?>
