以下代码将仅显示父分类术语的子分类术语。

$terms = get_the_terms($wp_query->post->ID, \'propertytype\');
 $props = array();
 foreach ($terms as $term) {
 if ($term->parent)
 $props[] = $term->name;
 }
 echo implode(\', \', $props);

例如：London（父）、West London（子）-上述内容仅与West London（子）相呼应。

但是，如果有多个子女级别，例如伦敦（父母）、西伦敦（子女）、切尔西（孙子女）

这行不通！我只想显示最后一个术语。

How would i modify the above to only display the last term even if there is more than one sub level?

谢谢

      //die(print_r($terms));
      $props = array();
      foreach ($terms as $term) { 
      $hasChildrenTest = get_term_children($term->ID, \'propertytype\');
          if ($term->parent) {
              if (empty($hasChildrenTest) && !is_wp_error($hasChildrenTest)) {
              $props[] = $term->name;
              }
          }
      }
      echo $props[0];

$terms = get_the_terms($wp_query->post->ID, \'propertytype\');
 $props = array();
