在woocommerce中显示当前产品的最深子类别

问题描述：

这似乎应该很容易做到，但我无法做到，也找不到任何关于它的帖子.

This seems like it should be easy to do but I haven't been able to, and cannot find any posts regarding it.

我可以显示与产品相关的所有类别或顶级类别，但如何仅显示产品的最低/最深类别?

I can display all the categories associated with a product, or the top category, but how do you echo only the lowest / deepest category for a product?

Cat-A [x]
  Cat-B [x]
    Cat-C [x]
  Cat-D [ ]
Cat-E [ ]
  Cat-F [ ]
    Cat-G [ ]
      Cat-H [ ]

如果这个例子是产品的祖先，我只想打印Cat-C".

If this example is the product's ancestry, all I want to print is "Cat-C".

但我不想像其他解决方案一样手动设置类别级别，我希望它始终打印最低的孩子，是存档页面上的产品，或单个产品页面.

But I don't want to manually set the category level like other solutions, I want it to always print the lowest child, be the product on the archive page, or single product page.

知道如何/应该如何做到这一点吗?

Any idea of how this can / should be done?

答

尝试类似:

// 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;
