Create subpage – filter parent pages list

3 comments

1. Not sure if this will help, but I have used the code on the following page to add a parent page filter to the list of pages:

   http://www.finalwebsites.com/add-a-parent-pages-filter-function-your-wordpress-admin-section/

   Very handy if you have a parent page for each section.

   There is just one problem – it only returns the children not grandchildren etc. I am just now trying to figure out how to get it to return results at all depths.

2. If you are using wp_dropdown_pages, then use the argument exclude_tree to exclude a parent and all of that parent’s child Pages. See here for an explanation of all arguments : http://codex.wordpress.org/Function_Reference/wp_dropdown_pages

3. Found a plugin but haven’t tried it: Parent Page Filter.

   The following function can show children of site-root-level pages. This is useful for many instances, but unfortunately not useful if you want to filter for children of any page that is not at site root. I don’t know PHP or WP well enough to suggest how to make this work on any page, instead of site-root-level pages.

   function fws_admin_posts_filter( $query ) {
       global $pagenow;
       if ( is_admin() && $pagenow == 'edit.php' && !empty($_GET['my_parent_pages'])) {
           $query->query_vars['post_parent'] = $_GET['my_parent_pages'];
       }
   }
   add_filter( 'parse_query', 'fws_admin_posts_filter' );
   
   function admin_page_filter_parentpages() {
       global $wpdb;
       if (isset($_GET['post_type']) && $_GET['post_type'] == 'page') {
           $sql = "SELECT ID, post_title FROM ".$wpdb->posts." WHERE post_type = 'page' AND post_parent = 0 AND post_status = 'publish' ORDER BY post_title";
           $parent_pages = $wpdb->get_results($sql, OBJECT_K);
           $select = '
               <select name="my_parent_pages">
                   <option value="">Parent Pages</option>';
           $current = isset($_GET['my_parent_pages']) ? $_GET['my_parent_pages'] : '';
           foreach ($parent_pages as $page) {
               $select .= sprintf('
                   <option value="%s"%s>%s</option>', $page->ID, $page->ID == $current ? ' selected="selected"' : '', $page->post_title);
           }
           $select .= '
               </select>';
           echo $select;
       } else {
           return;
       }
   }
   add_action( 'restrict_manage_posts', 'admin_page_filter_parentpages' );
