Chris's suggestion solved it. <pre><code>function remove_sidebar() { global $post; // We test if we are on the page 'Visualizations' if ( is_page('Visualizations') || $post->post_parent == '5' ) { // the page is "Visualizations", or the parent of the page is "Visualizations" // Yes, we are .. now we switch off the sidebar return FALSE; } else { // we are not .. we leave the switch on return TRUE; } } // Connect the filter to thematic_sidebar() add_filter('thematic_sidebar', 'remove_sidebar');</code></pre> And then I also used this in style.css to widen the content areas on all the child pages of parent page id=5 <pre><code>body.parent-pageid-5 #container { width: 960px; } body.parent-pageid-5 #content { width: 940px; }</code></pre> Thanks again david Chris on "Removing sidebar on child pages" http://themeshaper.com/forums/topic/removing-sidebar-on-child-pages#post-5506 Sun, 02 Aug 2009 18:31:58 +0000 Chris 5506@http://themeshaper.com/forums/ You can't use one of the globals without defining it. global $post; at the beginning of your function should resolve it.

You an also hide sidebars via css - but that's kind of cluncky dok_deleon on "Removing sidebar on child pages" http://themeshaper.com/forums/topic/removing-sidebar-on-child-pages#post-5503 Sun, 02 Aug 2009 16:01:07 +0000 dok_deleon 5503@http://themeshaper.com/forums/ I'm no php ninja myself, but this might help you... <a href="http://brams.dk/public/wp/tbr_article_family.zip">tbr_article_family</a> all you need to do is install and activate this plugin and use tbr_is_decendant_of("place page id here") for testing for subpages (and grandchildren). so this would make: <code> function remove_sidebar() { // We test if we are on the page 'Visualization, with an example page ID of 4' if ( is_page('Visualizations') || tbr_is_decendant_of(4)) { // the page is "Visualizations", or the parent of the page is "Visualizations" // Yes, we are .. now we switch off the sidebar return FALSE; } else { // we are not .. we leave the switch on return TRUE; } } // Connect the filter to thematic_sidebar() add_filter('thematic_sidebar', 'remove_sidebar'); </code> hope this helps :D awarner20 on "Removing sidebar on child pages" http://themeshaper.com/forums/topic/removing-sidebar-on-child-pages#post-5499 Sun, 02 Aug 2009 13:15:47 +0000 awarner20 5499@http://themeshaper.com/forums/ Not certain how it could be used in your code, but there is the child_of parameter for wp_list_pages. <code>wp_list_pages("title_li=&child_of=$id&show_date=modified</code> sunlamp on "Removing sidebar on child pages" http://themeshaper.com/forums/topic/removing-sidebar-on-child-pages#post-5498 Sun, 02 Aug 2009 12:54:49 +0000 sunlamp 5498@http://themeshaper.com/forums/ Hi Amy Thanks for your help. I customised the code with the Conditional Tags on the page you suggested. Now I've managed to remove the sidebar from the parent page, but not from any of its children.
