有条件的woocommerce结帐验证取决于购物车中的产品标签

Question

对于带有特殊产品标签的产品，我想在 woocommerce 结帐中设置另一个地址字段验证。 所以我的产品标签id是199，当带有这个标签的产品在购物车中时，验证应该是不同的。 我让它工作，但我的代码也会影响“正常”结帐，我想像往常一样进行验证。 它会产生一些额外的字段。

也许有人知道我做错了什么：

    add_filter( 'woocommerce_default_address_fields', 'schwinn_validation', 10, 1 );
    function schwinn_validation( $address_fields ) {
    $schwinn_cart=WC()->cart->get_cart();


    foreach( $schwinn_cart as $cart_item ){

        $product_array = $cart_item['data'];

        //echo $product_array->tag_ids[0];
        $product_tags_incart=$product_array->tag_ids[0];

        // wenn das Produkt mit tag id 199 getagt ist, wird eine andere validation durchgeführt

        if($product_tags_incart == 199 ){

        $address_fields['billing_phone']['required'] = false;
        $address_fields['billing_first_name']['required'] = false;
        $address_fields['billing_last_name']['required'] = false;
        $address_fields['billing_address_1']['required'] = false;
        $address_fields['billing_address_2']['required'] = false;
        $address_fields['billing_city']['required'] = false;
        $address_fields['billing_postcode']['required'] = false;
        $address_fields['billing_country']['required'] = false;
        $address_fields['billing_country']['required'] = false;
        $address_fields['billing_email']['required'] = false;

        return $address_fields;
    
        };
    }
    }

好的，我发现了问题所在，当没有标签 ID 为 199 的产品时，我也必须返回字段，谢谢您帮助我思考问题:-)

    add_filter( 'woocommerce_default_address_fields', 'schwinn_validation' , 10, 1);
    function schwinn_validation( $address_fields ) {
$schwinn_cart=WC()->cart->get_cart();


    foreach( $schwinn_cart as $cart_item ){

        $product_array = $cart_item['data'];

        //echo $product_array->tag_ids[0];
        $product_tags_incart=$product_array->tag_ids[0];

        // wenn das Produkt mit tag id 199 getagt ist, werden die Rechnungsadressenfelder ausgeblendet, weil das Produkt dann eine Kundenrechnung ist
            if($product_tags_incart == 199 ){

        $address_fields['billing_phone']['required'] = false;
        $address_fields['billing_first_name']['required'] = false;
        $address_fields['billing_last_name']['required'] = false;
        $address_fields['billing_address_1']['required'] = false;
        $address_fields['billing_address_2']['required'] = false;
        $address_fields['billing_city']['required'] = false;
        $address_fields['billing_postcode']['required'] = false;
        $address_fields['billing_country']['required'] = false;
        $address_fields['billing_country']['required'] = false;
        $address_fields['billing_email']['required'] = false;

        return $address_fields;
    
        }else{
                return $address_fields;
            };

    }
    }
