你今天有各种有趣的问题!还有一个WP_Term_Query 在WordPress中提供。这里有一些关于它的信息以及可以传递的参数。https://developer.wordpress.org/reference/classes/WP_Term_Query/__construct/
$term_args = array(
  \'taxonomy\' => array(\'tax_one\', \'tax_two\', \'tax_six\'),
  \'hide_empty\' => false,
  \'fields\' => \'all\',
  \'count\' => true,
);
$term_query = new WP_Term_Query($term_args);
foreach ( $term_query->terms as $term ) {
  // Here is what lives inside of $term when the \'field\' parameter above is set to all
  /*
  WP_Term Object (
      [term_id] => 11
      [name] => General Topics
      [slug] => general-topics
      [term_group] => 0
      [term_taxonomy_id] => 11
      [taxonomy] => category
      [description] => 
      [parent] => 0
      [count] => 22
      [filter] => raw
  )
  */
  // Maybe build out your array() in here to NOT have duplicate Terms ??
}
 希望有帮助!!
