如何在woocommerce上为特殊产品申请运费折扣？

Question

特殊产品的运费有任何折扣吗？

所有美国运费为 10.00 美元，但如果产品在购物车中，运费将为 3.00 美元我已经使用优惠券代码尝试过。如何查看账单/发货国家/地区？

但它对总成本设置了折扣，但我需要对运费进行折扣，我也使用不同的运输类别。

我正在尝试什么。

function shipping_costs_discounted( $rates, $package ){

 if ( is_admin() && ! defined( 'DOING_AJAX' ) )

    return $rates;

foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {

        $product_id_in_cart = array( 1391193 );// this is product ID

        if( in_array( $cart_item['product_id'], $product_id_in_cart ) ) {   

            //Looking for the shipping classes

            $shipping_class = 'special-offer-discount'; // <=== Shipping class slug

            $discount_rate  = 1.46;

            $is_found       = false;

            // Loop through cart items and checking for the specific defined shipping class

            foreach( $package['contents'] as $cart_item ) {

                if( $cart_item['data']->get_shipping_class() == $shipping_class )

                    $is_found = true;

            }

            // Set shipping costs shipping class is found

            if( $is_found ){

                foreach ( $rates as $rate_key => $rate ){

                    $has_taxes = false;

                    // Targeting "flat rate"

                    if( 'flat_rate' === $rate->method_id  ){

                        $rates[$rate_key]->cost = $rate->cost - $discount_rate;

                        // Taxes rate cost (if enabled)

                        foreach ($rates[$rate_key]->taxes as $key => $tax){

                            if( $tax > 0 ){

                                $has_taxes = true;

                                $taxes[$key] = $tax - $discount_rate;

                            }

                        }

                        if( $has_taxes )

                            $rates[$rate_key]->taxes = $taxes;

                    }

                }

            }

            return $rates;

        }

    }

}

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

假设您将修改woocommerce_package_rates过滤器，购物车中的所有商品都在key$package内的变量中contents，因此您可以简单地遍历它并提取所有 id 以检查您想要的产品是否在其中。目的地信息也在键$package里面的变量中destination，它包含完整的送货地址，包括国家；这是$package变量的json 输出示例{&nbsp; &nbsp; "contents": {&nbsp; &nbsp; &nbsp; &nbsp; "044a23cadb567653eb51d4eb40acaa88": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "key": "044a23cadb567653eb51d4eb40acaa88",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "product_id": 2754,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "variation_id": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "variation": [],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "quantity": 2,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "data_hash": "b5c1d5ca8bae6d4896cf1807cdf763f0",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_tax_data": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "subtotal": [],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "total": []&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_subtotal": 35.9,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_subtotal_tax": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_total": 35.9,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_tax": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "data": {}&nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; "0fc170ecbb8ff1afb2c6de48ea5343e7": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "key": "0fc170ecbb8ff1afb2c6de48ea5343e7",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "product_id": 2800,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "variation_id": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "variation": [],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "quantity": 1,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "data_hash": "b5c1d5ca8bae6d4896cf1807cdf763f0",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_tax_data": {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "subtotal": [],&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "total": []&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; },&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_subtotal": 107.95,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_subtotal_tax": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_total": 107.95,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "line_tax": 0,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "data": {}&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; },&nbsp; &nbsp; "contents_cost": 143.85,&nbsp; &nbsp; "applied_coupons": [],&nbsp; &nbsp; "user": {&nbsp; &nbsp; &nbsp; &nbsp; "ID": 1&nbsp; &nbsp; },&nbsp; &nbsp; "destination": {&nbsp; &nbsp; &nbsp; &nbsp; "country": "US",&nbsp; &nbsp; &nbsp; &nbsp; "state": "",&nbsp; &nbsp; &nbsp; &nbsp; "postcode": "",&nbsp; &nbsp; &nbsp; &nbsp; "city": "Pine Bluff",&nbsp; &nbsp; &nbsp; &nbsp; "address": "",&nbsp; &nbsp; &nbsp; &nbsp; "address_1": "",&nbsp; &nbsp; &nbsp; &nbsp; "address_2": ""&nbsp; &nbsp; },&nbsp; &nbsp; "cart_subtotal": 143.85,&nbsp; &nbsp; "rates": {&nbsp; &nbsp; &nbsp; &nbsp; "flat_rate:3": {}&nbsp; &nbsp; }}所以有了这些信息，你可以做这样的事情来修改运输成本和运输标签add_filter('woocommerce_package_rates', '_shipping_cost_product_ID', 100, 2);function _shipping_cost_product_ID( $rates, $package ){&nbsp; &nbsp; // duh&nbsp; &nbsp; if ( is_admin() && !
