特定类别的产品不影响免费送货

Question

我需要从特定产品类别中筛选产品，这些产品（数量）不会影响免费送货最低金额。

所以我想我用特殊产品的数量来增加最小数量。

示例： 免费送货从 40 欧元起。 客户以 35 欧元和 6 欧元的价格购买空间类别的产品。总计 = 41 欧元

通常他会免费送货。但不是他卡里的特殊产品。

这可能吗？

add_filter( 'woocommerce_package_rates', 'cardNo_freeShipping', 10, 2 );

foreach($items as $item => $values) {       
    $terms = get_the_terms( $values['product_id'], 'product_cat' );
    foreach ($terms as $term) {

}

也许你有更好的主意？谢谢;)

也许有人再次需要它......

这里是正确的代码：

            if($values['variation_id']) $price = get_post_meta($values['variation_id'] , '_price', true);   //If variation exist get price
            else $price = get_post_meta($values['product_id'] , '_price', true);                            //else get singel price
            $PriceArray[] = $price * $values['quantity'];
