   Hey,

   how do I request the number of parent categories of a category?

   I want to do the following:

   If the category has only a parent category (Sports > Soccer) I want to display text: If you like soccer you might like the following types of soccer as well.

   If the category has a grandparent category (Sports > Soccer > Soccer Tennis) I want to diplay a different text.

   How can I do this?

   Thanks

   One idea from
   http://codex.wordpress.org/Template_Tags/get_category_parents

   this function call
   <?php echo get_category_parents($cat, TRUE, ' || '); ?>
   returns a string of links for breadcrumbs, separated by ||
   Internet || Blogging || WordPress ||

   If you run that function on the category you are checking you could count the # of occurrences of '||' in the function's return string. If it is more than two then you know there is a grandparent category.

   $cat_list = get_category_parents($cat, TRUE, ' || ');
   if ( substr_count( $cat_list, '||' ) > 2 ) {
      // grandparent code here
   } else {
      // "no grandparent" code here
   }
