我制作了一个文件，在其中添加用户元字段，但它们仅为更新时的用户添加。当我创建用户时，不会添加它们。这是文件：

<?php
add_action(\'init\', function() {
  /**
   * Add new fields above \'Update\' button.
   *
   * @param WP_User $user User object.
   */
  function additional_profile_fields( $user ) {

      $departments = get_terms([\'taxonomy\' => \'department\', \'hide_empty\' => false]);
      $userDepartment = get_the_author_meta( \'department\', $user->ID );
      $regions = get_terms([\'taxonomy\' => \'region\', \'hide_empty\' => false]);
      $userRegion = get_the_author_meta( \'region\', $user->ID );
      $industries = get_terms([\'taxonomy\' => \'industry\', \'hide_empty\' => false]);
      $userIndustry = get_the_author_meta( \'industry\', $user->ID );
      $companies = get_terms([\'taxonomy\' => \'company\', \'hide_empty\' => false]);
      $userCompany = get_the_author_meta( \'company\', $user->ID );
