Try it like this: $args = array( ‘post_parent’ => $parentid, ‘post_type’ => ‘custom-type’ ); $posts = get_posts( $args ); if (is_array($posts) && count($posts) > 0) { // Delete all the Children of the Parent Page foreach($posts as $post){ wp_delete_post($post->ID, true); } } // Delete the Parent Page wp_delete_post($parentid, true);
You can first attempt and get a list of post’s children. If the returned value was empty, then the post has no child. Here’s how you do it: $args = array( ‘post_parent’ => get_the_ID(), // Current post’s ID ); $children = get_children( $args ); // Check if the post has any child if ( ! … Read more

This should work, using nothing more than the available argument-array parameters for wp_list_pages(): specifically, depth and child_of. To display one level of hierarchy, for descendant pages of the current page: <?php // Globalize the $post variable; // probably already available in this context, but just in case… global $post; wp_list_pages( array( // Only pages that … Read more

use ‘post_parent’ => 0 in WP_Query to return only parent posts
Great answers above. I took on the challenge trying to find yet another way to solve this. The exclude parameter: We could try: ‘exclude’ => wpse_exclude_drafts_branches() where: function wpse_exclude_drafts_branches() { global $wpdb; $exclude = array(); $results = $wpdb->get_col( “SELECT ID FROM {$wpdb->posts} where post_status=”draft” AND post_type=”page” ” ); $exclude = array_merge( $exclude, $results) ; while … Read more
