运输成本基于Woocommerce 3中的购物车总重量

问题描述

在我的Woocommerce网上商店中，我确实有不同的产品.我想根据购物车总重量计算运费:

In my Woocommerce Webshop I do have different Products. I would like to have shipping cost calculated on total cart items weight:

• 从0到6千磅的成本为 5 € ，
• 从6到12千磅的成本为 9 €

• from 0 to 6 Kilos the cost is 5 €,
• from 6 to 12 Kilos the cost is 9 €

实际上，如果我有一个商品为1公斤，则运费为 5 € ，但如果我的购物篮中有 10 件该商品，则运费费用仍为 5 € (应改为 9 € ).

Actually if I have a Product which is 1 Kilo the shipping cost is 5 €, but if I have 10 items of this product in my basket, the shipping fee is still 5 € (and it should be 9 € instead).

如何根据购物车总重量计算累进运费?

How can I have a progressive shipping cost based on cart total weight?

推荐答案

尝试以下功能，平均费用"的费用将根据购物车的总重量进行更改.

Try the following function which "Flat Rate" cost will be changed based on cart total weight.

使用统一费率"送货方式，您将需要设置参考送货费用，并且只需简单的初始费用，而不是任何公式.例如可以是1.这笔费用将由我的答案代码取代，并根据购物车总重量动态变化.

Using "Flate rate" shipping method, you will need to set a reference shipping cost with a simple initial cost instead of any formula. It can be for example 1. This cost will be replaced by my answer code, dynamically based on cart total weight.

add_filter('woocommerce_package_rates', 'shipping_cost_based_on_weight', 12, 2);
function shipping_cost_based_on_weight( $rates, $package ){
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return $rates;

    // HERE define the differents costs
    $cost1 = 5; // Up to 6 Kg
    $cost2 = 9; // Above 6 Kg and below 12 kg
    $cost3 = 9; // Above 12 kg

    // The cart total Weight
    $total_weight = WC()->cart->get_cart_contents_weight();

    // Loop through the shipping taxes array
    foreach ( $rates as $rate_key => $rate ){
        $has_taxes = false;
        // Targetting "flat rate"
        if( 'flat_rate' === $rate->method_id ){
            // Get the initial cost
            $initial_cost = $new_cost = $rates[$rate_key]->cost;

            // Calculate new cost
            if( $total_weight <= 6 ) { // Below 6 Kg
                $new_cost = $cost1;
            }
            elseif( $total_weight > 6 && $total_weight <= 12 ) { // Between 6 and 12 Kg
                $new_cost = $cost2;
            }
            else { // Above 12 Kg
                $new_cost = $cost3;
            }

            // Set the new cost
            $rates[$rate_key]->cost = $new_cost;

            // Taxes rate cost (if enabled)
            $taxes = [];
            // Loop through the shipping taxes array (as they can be many)
            foreach ($rates[$rate_key]->taxes as $key => $tax){
                if( $rates[$rate_key]->taxes[$key] > 0 ){
                    // Get the initial tax cost
                    $initial_tax_cost = $new_tax_cost = $rates[$rate_key]->taxes[$key];
                    // Get the tax rate conversion
                    $tax_rate    = $initial_tax_cost / $initial_cost;
                    // Set the new tax cost
                    $taxes[$key] = $new_cost * $tax_rate;
                    $has_taxes   = true; // Enabling tax
                }
            }
            if( $has_taxes )
                $rates[$rate_key]->taxes = $taxes;
        }
    }
    return $rates;
}

代码进入您的活动子主题(或活动主题)的function.php文件中.经过测试，可以正常工作.

Code goes in function.php file of your active child theme (or active theme). Tested and works.
