仅显示 WooCommerce 主要产品类别

Question

这是我为视觉作曲家制作的简码。它存储了我的 woocommerce 类别，但我想不出我会如何停止它显示子类别而只显示主要类别。

有什么想法吗？

谢谢

Answer 1

要仅显示主要产品类别，您需要以这种方式添加 'parent' 参数：

$term_args = array(
    'parent' => 0,
    'hide_empty' => $empty , 
    'number' => $num , 
    'order_by' => $sort , 
    'order' => $order,
);

$terms = get_terms( 'product_cat', $term_args);

那么您将只获得主要产品类别而没有子类别。
