包含所有产品的WooCommerce类别树

Question

我需要在每个类别下显示类别树和产品的完整列表。

我用WP_Query获取产品的完整列表，但仍然无法显示类别/子类别，并在其中的每个下面列出相关产品。我正在寻找一种对数据库的查询要求最少的方法。

任何帮助？ （不需要html或jquery，我只需要结果数组）

Answer 1

最终结果将是这样的。

SUBCAT 1

-----产品1

-----产品2

----- SUBCAT 1

的子类别1 ----- ---产品1

--------产品2

--------产品3

SUBCAT 2

-----产品1

-----产品2

-----产品3
