Unlimited number of child pages using wp_list_pages

Compact Archives Review

Adding this snippet to the sidebar.php of your wordpress theme will use wp_list_pages to display all child pages regardless of depth. This is something I have not found online and needed for a current theme I'm working on, enjoy!

( example screenshot )

	if ($post->post_parent) {
	        $parent = $ancestors[$root];
	} else {
	        $parent = $post->ID;

	$children = get_pages('child_of='.$parent);
	$child_pages = array(1);

	foreach($children as $child) {
	$all_pages = implode(",",$child_pages);

	if( count( $children ) != 0 ) {
	echo '<ul class="sidebar-navigation">'.
		wp_list_pages( 'title_li=&sort_column=menu_order&echo=0&include='.$all_pages )
