Use ACF field to populate Title AND update slug

//Auto add and update Title field:
function my_post_title_updater( $post_id ) {

    $my_post = array();
    $my_post['ID'] = $post_id;
    $my_post['post_name'] = '';
    $posttypes = array( 'accommodation', 'destination' );
    $currentposttype = get_post_type($post_id);

    if ( in_array( $currentposttype, $posttypes ) ) {
      $my_post['post_title'] = get_field('title', $post_id);
    }

    //Unhook function to prevent infitnite looping
    remove_action('acf/save_post', 'my_post_title_updater', 20);

    // Update the post into the database
    wp_update_post( $my_post );
    // slug will be generated by WP based on post title

    //Rehook function to prevent infitnite looping
    add_filter('acf/save_post', 'my_post_title_updater', 20);

}

// run after ACF saves the $_POST['fields'] data
add_action('acf/save_post', 'my_post_title_updater', 20);
