   Hi there

   I'm finding the 'Removing the Sidebar' code snippet at the Code Bar very helpful

   http://www.wupperpiraten.de/2009/03/how-to-remove-the-sidebar-from-a-certain-page/

   However my PHP isn't up to much.

   Can anyone suggest how I can make this code work to remove the sidebars from all the child pages of a given page?

   Thanks for your help!

   I've not attempted this myself - but maybe there's an answer for you here

   http://codex.wordpress.org/Conditional_Tags

   scroll down to:

   "Testing for sub-Pages"

   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. Is there something I'm doing wrong?

   // remove sidebar for certain pages
   // http://www.wupperpiraten.de/2009/03/how-to-remove-the-sidebar-from-a-certain-page/
   // filter thematic_sidebar() .. no display for the page 'Visualizations' & its children
   
   function remove_sidebar() {
   	// We test if we are on the page 'Visualization'
   	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');
   
   ?>

   Not certain how it could be used in your code, but there is the child_of parameter for wp_list_pages.

   wp_list_pages("title_li=&child_of=$id&show_date=modified

   I'm no php ninja myself, but this might help you... tbr_article_family
   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:

   
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');


   hope this helps :D

   If you can't find an answer another option is to make a custom page template with no sidebars and use that.

   You an also hide sidebars via css - but that's kind of cluncky

   You can't use one of the globals without defining it.

   global $post;

   at the beginning of your function should resolve it.

   Thanks all!

   Chris's suggestion solved it.

   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');

   And then I also used this in style.css to widen the content areas on all the child pages of parent page id=5

   body.parent-pageid-5 #container {
   	width: 960px;
   }
   
   body.parent-pageid-5 #content {
   	width: 940px;
   }

   Thanks again
   david
