I won’t give a solution to your actual issue but I will show you how you can verify if current page is child of a specific top level page. If you need to check the current page has specific Parent page the you can do like this: <?php $currentPage = get_the_id(); $pageAncestors = get_post_ancestors($currentPage); $hasParent … Read more
I realized the reason it doesn’t work: this function needs to be located in functions.php. Per WP code reference: pre_get_posts “Fires after the query variable object is created, but before the actual query is run.” Since I placed the function within an archive template, the main query had already fired, and was thus too late.
How to customize ‘children comments’ in WordPress?
Search anything from a Child and Sub-Pages of their Parent page
You can use get_query_var( ‘term’ ) to get the current term and get_query_var( ‘taxonomy’ ) to get the current taxonomy, then all that is left is to use [wp_dropdown_categories()][1] function withchild_ofparameter andtaxonomy` parameter, so something like this: //first get the current term $current_term = get_term_by( ‘slug’, get_query_var( ‘term’ ), get_query_var( ‘taxonomy’ ) ); //then set … Read more
I think you need to use depth=1 rather than depth=2. You are specifying, via the child_of argument, that you want to display children of the current Page’s parent Page. That means that the first level of hierarchy is the current Page (and any of its siblings). The second level of hierarchy would be child pages … Read more
The posts query is not recursive by nature. And I don’t think that post_parent accepts multiple IDs, so you will likely need to loop and run this for multiple pages or play with query filters to do this in less requests (if performance becomes an issue).
POST does not have parents, but categories. Only PAGE can have parent. So, the question is, what do you want to get? In case of getting POSTS from different categories, just use get_posts and add multiple categories. As for pages, just use get_page_children.
OK, I almost got it now… I extended the Walker_Page Class: class Walker_Child_Classes extends Walker_page { function start_el(&$output, $page, $depth, $args, $current_page) { if ( $depth ) $indent = str_repeat(“\t”, $depth); else $indent=””; extract($args, EXTR_SKIP); $output .= $indent . ‘<li class=”‘ . apply_filters( ‘the_title’, $page->post_name, $page->ID ) . ‘”><a href=”‘ . get_page_link($page->ID) . ‘” title=”‘ … Read more
Instead of: $args = array( ‘order’ => ‘ASC’, ‘orderby’ => ‘menu_order’, ‘post_type’ => ‘attachment’, ‘post_parent’ => $post->ID, ‘post_mime_type’ => ‘image’, ‘numberposts’ => 1, ); Use: $args = array( ‘order’ => ‘ASC’, ‘orderby’ => ‘menu_order’, ‘post_type’ => get_post_type($post), ‘post_parent’ => $post->ID, ‘numberposts’ => 1, ); You could also use post/page/etc or ‘any’
