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);

Answer 1

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

{

    "contents": {

        "044a23cadb567653eb51d4eb40acaa88": {

            "key": "044a23cadb567653eb51d4eb40acaa88",

            "product_id": 2754,

            "variation_id": 0,

            "variation": [],

            "quantity": 2,

            "data_hash": "b5c1d5ca8bae6d4896cf1807cdf763f0",

            "line_tax_data": {

                "subtotal": [],

                "total": []

            },

            "line_subtotal": 35.9,

            "line_subtotal_tax": 0,

            "line_total": 35.9,

            "line_tax": 0,

            "data": {}

        },

        "0fc170ecbb8ff1afb2c6de48ea5343e7": {

            "key": "0fc170ecbb8ff1afb2c6de48ea5343e7",

            "product_id": 2800,

            "variation_id": 0,

            "variation": [],

            "quantity": 1,

            "data_hash": "b5c1d5ca8bae6d4896cf1807cdf763f0",

            "line_tax_data": {

                "subtotal": [],

                "total": []

            },

            "line_subtotal": 107.95,

            "line_subtotal_tax": 0,

            "line_total": 107.95,

            "line_tax": 0,

            "data": {}

        }

    },

    "contents_cost": 143.85,

    "applied_coupons": [],

    "user": {

        "ID": 1

    },

    "destination": {

        "country": "US",

        "state": "",

        "postcode": "",

        "city": "Pine Bluff",

        "address": "",

        "address_1": "",

        "address_2": ""

    },

    "cart_subtotal": 143.85,

    "rates": {

        "flat_rate:3": {}

    }

}

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 ){

    // duh

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

        return $rates;

    // The ID of the product you want to modify shipping cost if found in cart

    $discounted_product_id = 2800;

    // Get all the product IDs added in cart and put them in array

    $ids_in_cart = [];

    foreach ( $package['contents'] as $key => $item ) {

        $ids_in_cart[] = $item['product_id'];

    }

    // loop through each shipping rates

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

        $has_taxes = false;

        // Only modify shipping if all conditions below are meet

        if( 

            'flat_rate' === $rate->method_id // if shipping method is "Flat RATE"

            && ( isset($package['destination']['country'] ) && $package['destination']['country'] == 'US' )  // if country is US

            && in_array($discounted_product_id, $ids_in_cart )//if $discounted_product_id is in cart

            ) {

            $rates[$rate_key]->label = 'Cool Shipping'; // Modify Shipping Name

            $rates[$rate_key]->cost = 3.00; // Modify Shiping Cost

            //Taxes rate cost (if enabled)

            $taxes = [];

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

                if( $rates[$rate_key]->taxes[$key] > 0 ){

                    $initial_tax_cost = $new_tax_cost = $rates[$rate_key]->taxes[$key];

                    $tax_rate    = $initial_tax_cost / $initial_cost;

                    $taxes[$key] = $new_cost * $tax_rate;

                    $has_taxes   = true; 

                }

            }

            if( $has_taxes ) $rates[$rate_key]->taxes = $taxes;

        }

    }

    return $rates;
