Home Forums Front-end Issues Nested Post Object Fields Reply To: Nested Post Object Fields

  • I have a question on this topic. I have three post types. Notebooks -> Notebook Sections -> Notebook Pages. I have added two post object fields to the notebook pages. The first one picks the notebook the page goes into and I want the second one to only pull up the notebook sections that are children of the notebook selected. I also have a post object field on the notebook sections to choose the notebook parent to attach it to. This is the code I am using in my functions.php for that one.

    function my_acf_save_post( $post_id ) {
        // Get the selected post status
        $value = get_field('notebook_section_post_parent', $post_id);
        // Update current post
        $post = array(
          'ID'           => $post_id,
          'post_parent'   => $value,
        // Remove the action to avoid infinite loop
        remove_action('acf/save_post', 'my_acf_save_post', 20);
        // Update the post into the database
        wp_update_post( $post );
        // Add the action back
        add_action('acf/save_post', 'my_acf_save_post', 20);
    // run after ACF saves the $_POST['acf'] data
    add_action('acf/save_post', 'my_acf_save_post', 20);

    So, how do I make the notebook section field on the notebook pages only pull up the children of the notebook selected? I’m really new to coding, so I just can’t wrap my head around it and how to do it without it all getting so complicated. I appreciate ANY advice. Thanks!
