   I want to display a specific block of html when viewing an archive page based on on category.

   I have a category "news (id 1)" with 5 children categories;

   If I use (is_category ('1')) the html only appears when the news category is being browsed, but if I go to any of the children categories the html does not display;

   I know I can use an array, is_category(array(1,'news-cat-1','news-cat-2')); but then I have to manually edit the code every time I add a child category to news.

   Is there a way to make it so that when the user is viewing the news category or any of it's children the html display?

   thanks in advance for any guidance..

   Maybe this will help:
   

   <?php
   $current_cat = intval( get_query_var('cat') );
   $news = get_cat_ID('news');
   $taxonomy = 'category';
   $children = get_term_children( $news, $taxonomy );
   if (in_array($current_cat, $children)) {
     echo 'current category is a child of the news category';
   }
   ?>

   OK - that sort of worked...

   It displays the html I want for all children categories, but now it does not display it for the parent category...

   Any ideas

   Thanks again for your help

   Sorry, wouldn't you need something like:

   if (in_array($current_cat, $children) && is_category ('1')) {

   nope - now it does not bring back anything at all...

   Here's what I have:
   

   <?php
   $current_cat = intval( get_query_var('cat') );
   $news = get_cat_ID('Press Room');
   $taxonomy = 'category';
   $children = get_term_children( $news, $taxonomy );
   if (in_array($current_cat, $children) && is_category('428')) {
   ?>

   428 is the "Press Room" Category ID - I have - Press room has the child category "Press Releases" and Press Realeses has children categories of 2010, 2009, etc...

   Thanks again...
