Php 如何仅显示当前产品父级中的第三个产品类别子级？-吴哥商业

我很想找到这个问题的答案！ 我的WooCommerce产品类别树如下所示：

域
-域1
--Cuvee1
--Cuvee2
--Cuvee3
-域2
-域3
葡萄酒
-胭脂
-布兰科
-罗斯
彩页
-Cépage1
-Cépage2
-Cépage3

在我的一个产品页面上，我选择了Domain1、Cuvee1、Rouge和Cépage1 出于设计目的，我希望只显示Cuvee1，而不显示其他产品类别

到目前为止，我尝试了在网站上找到的几个选项，并尝试对它们进行一些调整，但没有得到任何结果：

代码测试1：

<?php
// get all product cats for the current post
$categories = get_the_terms( get_the_ID(), 'product_cat' ); 
// wrapper to hide any errors from top level categories or products without category

if ( $categories && ! is_wp_error( $category ) ) : 
    // loop through each cat
    foreach($categories as $category) :
      // get the children (if any) of the current cat
      $children = get_categories( array ('taxonomy' => 'product_cat', 'parent' => $category->term_id ));

      if ( count($children) == 0 ) {
          // if no children, then echo the category name.
          echo $category->name;
      }
    endforeach;

endif;

<?php
$terms = get_the_terms( $post->ID, 'product_cat' );                    //Get all terms associated with post in woocommerce's taxonomy 'product_cat'
$term_ids = wp_list_pluck($terms,'term_id');                                            //Get an array of their IDs
$parents = array_filter(wp_list_pluck($terms,'parent'));                                       //Get array of parents - 0 is not a parent
$term_ids_not_parents = array_diff($term_ids,  $parents);                                            //Get array of IDs of terms which are not parents.
$terms_not_parents = array_intersect_key($terms, $term_ids_not_parents);                       //Get corresponding term objects.

foreach($terms_not_parents as $term_not_parent)                                            //Extract the name of the category from the array and post it.
echo $term_not_parent->name;

<?php
global $post;
$cuvee_id = get_term_by('slug', 'domaines', 'product_cat');

$terms = get_the_terms($post->ID, 'product_cat');
foreach ($terms as $term) {
    if($term->parent === $cuvee_id->term_id) {
        echo $term->name;
    }
}
?>
