    I want to make the Post Title the same value as one of the fields in my "Monitor" CPT automagically and I have 3 questions on how to do this.

    Q1) To do this I thought I could use the rwmb_before_save_post (or rwmb_{$meta_box_id}_before_save_post) action but I'm not getting the syntax right because it doesn't even appear to be getting to my code. I have this test code in my functions.php file:

    function update_post_title( $object_id ) {
    die("I got here!");
    //var_dump($object_id);
};
add_action( 'rwmb_before_save_post', 'update_post_title', 10, 1 );

    Q2) Once my function is called successfully, how do I make the Post Title the same as my 'Monitor ID' field (I need this to link 2 metaboxes together)?

    Q3) I think I should be using rwmb_{$meta_box_id}_before_save_post but I'm not sure where to find the $meta_box_id. Is it the CPT "post=14" number, the Field Group "post=13" number, or something else?

    I've added the following code to my functions.php but it is not updating the title.

    add_action( 'rwmb_monitor_after_save_post', 'update_post_title' );

function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'monitor_number', '', $post_id );

    // Get the post title
    //$my_post_title = get_the_title( $post_id ); NOT NEEDED - I'M OVERWRITING THE TITLE
    
    // Preprare update post
    $my_post = array(
        'ID' => $post_id,
        'post_title' => $my_meta,
    );

    wp_update_post( $my_post );
}

    My CPT slug is "monitor" and my field slug is "monitor_number".

    What am I doing wrong?

    Hi,

    You need to change the CPT slug to the meta box ID. If you are using the Builder, it is the Field Group ID, screenshot https://share.getcloudapp.com/nOuvkr6A

    So the sample action hook would be

    add_action( 'rwmb_post-meta_after_save_post', 'update_post_title' );

    Long, Hope you are well.

    Suppose I wanted to customize the slug on save (from frontend submission form) in this same way, what would I place here (would it be post_slug)?:

    (from your code above in this thread):

    
add_action( 'rwmb_monitor_after_save_post', 'update_post_title' );

function update_post_title( $post_id ) {
    // Get the field value
    $my_meta = rwmb_meta( 'monitor_number', '', $post_id );

    // Get the post title
    //$my_post_title = get_the_title( $post_id ); NOT NEEDED - I'M OVERWRITING THE TITLE
    
    // Preprare update post
    $my_post = array(
        'ID' => $post_id,
        'post_slug' => $my_meta,
    );

    wp_update_post( $my_post );
}

    @Long, here is my finished code for above^. Is it post_name I need to update?:

    
<?php
add_action( 'rwmb_distributor-details_after_save_post', 'update_post_slug' );

function update_post_slug( $post_id ) {
  // Get the street_address field value
  $dist_address = rwmb_meta( 'street_address', '', $post_id );

  // Get the locality field value
  $dist_city = rwmb_meta( 'locality', '', $post_id );

  // Get the administrative_area_level_1 field value
  $dist_state = rwmb_meta( 'administrative_area_level_1', '', $post_id );

  // Get the post title
  $dist_post_title = get_the_title( $post_id );

  // Preprare update post slug (post_name)
  $my_post = array(
      'ID' => $post_id,
      'post_name' => $dist_post_title . '-' . $dist_address . '-' . $dist_city . '-' . $dist_state,
  );

  wp_update_post( $my_post );
}

    Hi Scott,

    Yes, correctly. Using the argument post_name to update the post slug. Read more on the documentation https://developer.wordpress.org/reference/classes/wp_post/
