    I've been using the following code successfully for some time. It allows me to leave a post title field blank and instead, combine 2 meta fields to create the post title. see below:

    add_action( 'rwmb_event-fields_after_save_post', 'update_event_title' );
    function update_event_title( $post_id ) {
    $t1 = rwmb_meta( 'event_name', '', $post_id );
    $t2 = rwmb_meta( 'event_start', '', $post_id );
    $my_post_title = get_the_title( $post_id );
    $my_post = array(
    'ID' => $post_id,
    'post_title' => $t1 . '-' . $t2,
    'post_name' => $t1 . '-' . $t2
    );
    wp_update_post( $my_post );
    }

    but, now I'm doing something more complex and the above code format isn't working for me.

    I have a CPT 'Event' and a custom field group 'Create Event Fields'. in the field group, I am using a GROUP with ID 'event_details' and within that group are 4 meta fields:

    • Event Name (event_name)
    • Event Start Date (event_start_date)
    • Event Start Time (event_start_time)
    • Event End Time (event_end_time)

    I'm trying to use the following to combine (event_name) and (event_date) to create the ppost title, but it's not working. I think it's because these fields are contained within a group, but I've tried many variations to call the correct fields and I can't figure it out. Here is my last try:

    add_action( 'rwmb_create-event-fields_after_save_post', 'update_event_title' );
        function update_event_title( $post_id ) {
            $t1 = rwmb_meta( 'event_details_event_name', '', $post_id );
        $t2 = rwmb_meta( 'event_details_event_start_date', '', $post_id );
            
    $my_post_title = get_the_title( $post_id );
            $my_post = array(
                'ID' => $post_id,
                'post_title' => $t1 . '-' . $t2,
                'post_name' => $t1 . '-' . $t2
        );
        wp_update_post( $my_post );
    }

    Any suggestions?
