我试图在WP Job Manager中的单个帖子（作业列表）中显示作业类别。

我尝试了下面的代码，但它显示“Array”。

function get_the_job_category( $id = false ) {
  $categories = get_the_terms( $id, \'job_category\' );
  if ( ! $categories || is_wp_error( $categories ) )
    $categories = array();

  $categories = array_values( $categories );

  foreach ( array_keys( $categories ) as $key ) {
    _make_cat_compat( $categories[$key] );
  }

  /**
   * Filters the array of categories to return for a post.
   *
   * @since 3.1.0
   * @since 4.4.0 Added `$id` parameter.
   *
   * @param array $categories An array of categories to return for the post.
   * @param int   $id         ID of the post.
   */
  return apply_filters( \'get_the_job_categories\', $categories, $id );
}
