问题

我有按类型插件“自定义分类法”创建的产品类别。我想在有人单击类别名称时按类别显示产品，该名称应仅显示注册到例如“acril”类别的产品。问题是，当我调试产品时，它并没有显示类别。因此，如果您注意到我在第1圈中有数据过滤器，在第二圈中有值为“category”的数据cat，我应该连接两个foreach圆圈。这应该是动态的，若post并没有显示任何键，那个么什么才是连接的关键。

<? $products = get_posts( array(\'post_type\' => \'products\', \'posts_per_page\' => 400,) ); ?>

<? $products = get_posts( array(\'post_type\' => \'products\',  \'category_name\' => \'category_name_here\', \'posts_per_page\' => 400,) ); ?>
