   I'm displaying sub-categories on the Categories page - similar to the way contents are displayed on WordPress Codex pages. I'm using blocks with predefined heights to display individual posts within the categories page and floating the "sub-category list" with them. If I don't specify the height of the list, the boxes are not aligned.

   • I need to specify the height of the "sub-category list".
     • A default height is defined in the stylesheet.
     • To dynamically adjust the height of the list, I'm using inline styling.
   • To define the height of the list using inline styling (to a pre-defined value), I need to first determine the number of sub-categories in the list (prior to executing wp_list_categories).

   Before, this is what I used and it worked like a champ:
   

   $currentcat=get_query_var('cat');
   $categories= get_categories('child_of='.$currentcat.'&depth=1');
   $catcount = count($categories);

   $catcount was used to determine the height then specify it with inline styling. Then inside the div I ran:
   

   foreach ($categories as $cat) {
   $catlist = '<li><a href="'.$cat->category_nicename.'">';
   $catlist .= $cat->cat_name;
   $catlist .= '</a></li>';
   echo $catlist;
   }

   Now I want to exclude child categories - I only want to go 1 level deep with sub-categories in the list.

   So I need to do one of two things from what I can tell:

   1. Count the number of results from wp_list_categories prior to executing it.

   OR

   2. Count the number of results (only 1 level deep) using get_categories.

   Here's the wp_list_categories I'm running:
   wp_list_categories ('title_li=&child_of='.$currentcat.'&depth=1&show_count=1');

   Any suggestions would be appreciated.

   The ugly way?

   <?php
   $cats=get_categories ();
   $catcount=0;
   foreach ( (array) $cats as $cat ) {
   if ($cat->category_parent=='0') {
   $catcount++;
   }
   }
   ?>

   I changed the '0' in
   if ($cat->category_parent=='0')
   to $currentcat & the ugly way works beautifully.

   Thanks for the solution Michael.
