Post Title when creating a post via an ACF Form

  • Hello. I was able to successfully set up ACF to create and save post titles using the ACF v4. However, this is not working when I switched to v5.

    This is the code that worked in v4:

    // Create Post
    add_filter('acf/pre_save_post' , 'create_universe_form' );
    function create_universe_form( $post_id ) {
      // bail early if not a new post
      if( $post_id !== 'new_universe' ) {
        return $post_id;
      // vars
      $title = $_POST['fields']['field_590cecb75ba1b'];
      // Create a new post
      $post = array(
        'post_status'	=> 'publish',
        'post_type'		=> 'universe',
        'post_title'	=> $title,
      // insert the post
      $post_id = wp_insert_post( $post );
      // Update $_POST Return
      $url = get_permalink($post_id);
    	$_POST['return'] = ($url);
      // return the new ID
      return $post_id;

    I’m not sure what the differences are between v4 and v5 and if I need to change something. It was definitely working in v4 though. But now, in v5, it isn’t saving the post title nor the URL.

    EDIT: Quick update, it IS working when I update an existing post. It’s only when **creating** a new post does it not save the title.

  • Hi @malachidraven

    Thanks a lot for reaching out to us.

    Is it possible that the field group ID changed during the migration?

    Kindly try doing a var_dump of the $_POST and let me know how it goes.

    Hope to hear from you soon.

  • I changed “[‘fields’]” to “[‘acf’]” and also updated the “[‘field_590cecb75ba1b’]” to the new ID. Somehow that made the URL work when creating a post, but it’s still not actually saving a title.

  • Hi @malachidraven

    Kindly open a personalized support ticket as [email protected] so I may be able to debug the issue further.

    Hope to hear from you soon.
