   The following code displays the sub pages of a main page whether you are on the main page or a sub page.

   I want to adapt it to show sub categories whether on the category page or the sub category page. The second set of code is where I am stuck.

   Thanks for any help!!!

   <?php
     //if you are on a page NOT a cat
     if ($post->ID) {
       //if you are on the sub page display the parents sub pages
       //if you are on a page display the sub pages
       if($post->post_parent)
         $children = wp_list_pages("title_li=&amp;child_of=".$post->post_parent."&amp;echo=0");
       else
         $children = wp_list_pages("title_li=&amp;child_of=".$post->ID."&amp;echo=0");
       if ($children) { ?>
         <ul>
         <?php echo $children; ?>
         </ul>
     <?php }} ?>

   <?php
     if ($_GET[cat]) {
       if($post->post_parent) //what is the category equivalent??
         $children = wp_list_categories("title_li=&amp;child_of=".$post->post_parent."&amp;echo=0");
       else
         $children = wp_list_categories("title_li=&amp;child_of=".$_GET[cat]."&amp;echo=0");
       if ($children) { ?>
         <ul>
         <?php echo $children; ?>
         </ul>
     <?php }} ?>

   For those who are interested ---

   <?php
   $cat = get_query_var('cat');
   $category = get_category ($cat);
   
   if ($category->cat_ID) {
   
   if($category->category_parent)
   $children = wp_list_categories("orderby=id&hide_empty=0&title_li=&child_of=".$category->category_parent."&echo=0");
   else
   $children = wp_list_categories("orderby=id&hide_empty=0&title_li=&child_of=".$category->cat_ID."&echo=0");
   if ($children) { ?>
   
         <?php echo $children; ?> 
   
   <?php }} ?>

   Not sure if you ever got the recognition you deserve, but this worked great, out of the box.

   Can anyone help me modify it so that if there are no children, it echos nothing? I'm assume an elseif statement at the end, but I'm not yet strong enough in PHP to get the markup correct, though I am doing some trial and error.

   I found a solution to my above question...using str_replace to remove the "No categories" line that wp_list_pages returned on finding no children with the above code from deanes02.
