根据购物车物品重量和购物车数量计算运费 [英] Shipping calculated on cart items weight and cart amount

问题描述

在客户端 WooCommerce 网站中，为最多 250 个订单启用免费送货方式.我使用下面的代码(来自 这个答案)，当订单金额超过 250 时隐藏其他运费，除非有重购物车中的商品.

In a client WooCommerce web site, free shipping method is enabled for orders amount up to 250. I use the code below (from this answer), to hide other shipping rates when the order amount is over 250, except when there is heavy items in cart.

add_filter( 'woocommerce_package_rates', 'conditionally_hide_other_shipping_based_on_items_weight', 100, 1 );
function conditionally_hide_other_shipping_based_on_items_weight( $rates ) {
    // targeted weight
    $target_product_weight = 12;
    $target_cart_amount = 250;

    WC()->cart->subtotal_ex_tax >= $target_cart_amount ? $passed = true : $passed = false ;

    // Iterating trough cart items to get the weight for each item
    foreach(WC()->cart->get_cart() as $cart_item){
        if( $cart_item['variation_id'] > 0)
            $item_id = $cart_item['variation_id'];
        else
            $item_id = $cart_item['product_id'];

        // Getting the product weight
        $product_weight = get_post_meta( $item_id , '_weight', true);

        if( !empty($product_weight) && $product_weight >= $target_cart_amount ){
            $light_products_only = false;
            break;
        }
        else $light_products_only = true;
    }

    // If 'free_shipping' method is available and if products are not heavy
    // and cart amout up to the target limit, we hide other methods
    $free = array();
    foreach ( $rates as $rate_id => $rate ) {
        if ( 'free_shipping' === $rate->method_id && $passed && $light_products_only ) {
            $free[ $rate_id ] = $rate;
            break;
        }
    }

    return ! empty( $free ) ? $free : $rates;
}

但现在，我想设置一个可变的运费，它将以两种方式计算:

But now, I would like to set a variable shipping amount that will be calculated in 2 ways:

• 当订单金额低于 250 件时，将按订单商品总重量计算 1 欧元/公斤.
• 当订单金额达到 250 件时，将仅计算重件重量(1 欧元/公斤).如果没有重物，可享受免费送货服务.

我怎样才能做到这一点，因为它有点复杂?
有什么要跟踪的吗?

How can I achieve this, as it’s a bit complicated?
Any track to follow?

我已经尝试了一些现有的相关插件，但它们不适合这种情况.

I have tried some existing related plugins, but they aren't convenient for this case.

谢谢.

推荐答案

代码改进 (2019 年 3 月):

是的，如果没有带有自定义运费的插件，这是可能的，根据购物车物品重量和购物车数量计算......但您需要有一个'Flat rate' 运输方式设置最低数量.这通常应该适用于您正在使用的代码.

Yes this is possible without a plugin with a custom SHIPPING FEE, calculated on cart items weight and cart amount… But you will need to have a 'Flat rate' shipping method set with a minimal amount. This normally should work with the code you are using.

这是代码(评论):

//Adding a custom Shipping Fee to cart based conditionaly on weight and cart amount
add_action('woocommerce_cart_calculate_fees', 'custom_conditional_shipping_fee', 10, 1);
function custom_conditional_shipping_fee( $cart ){

    ## --- YOUR SETTINGS --- ##
    $targeted_weight      = 20;  // Your targeted "heavy" product weight
    $targeted_cart_amount = 250; // Your targeted cart amount
    $price_per_kg         = 1;   // Price by Kg;
    $flat_rate_price      = 10;  // Set the cost like in 'flat rate' shipping method

    // Initializing variables
    $fee = $calculated_weight = 0;

    // For cart SUBTOTAL amount EXCLUDING TAXES
    $passed = $cart->subtotal_ex_tax >= $targeted_cart_amount ? true : false ;

    // For cart SUBTOTAL amount INCLUDING TAXES (replace by this):
    // $passed = $cart->subtotal >= $targeted_cart_amount ? true : false ;

    // Iterating through each cart items
    foreach( $cart->get_cart() as $cart_item ){
        // The Product weight
        $product_weight = $cart_item['data']->get_weight();

        // cart item weight
        $cart_item_weight = $cart_item['quantity'] * $cart_item['data']->get_weight();

        // When cart amount is up to 250, Adding weight of heavy items
        if($passed && $product_weight > $targeted_weight)
            $calculated_weight += $cart_item_weight;
    }

    #### Making the fee calculation ####

    // Cart is up to 250 with heavy items
    if ( $passed && $calculated_weight != 0 ) {
        // Fee is based on cumulated weight of heavy items
        $fee = ( $calculated_weight * $price_per_kg ) - $flat_rate_price;
    }
    // Cart is below 250
    elseif ( ! $passed ) {
        // Fee is based on cart total weight
        $fee = ( $cart->get_cart_contents_weight( ) * $price_per_kg ) - $flat_rate_price;
    }

    #### APPLYING THE CALCULATED FEE ####

    // When cart is below 250 or when there is heavy items
    if ($fee > 0){
        // Rounding the fee
        $fee = round( $fee );
        // This shipping fee is taxable (You can have it not taxable changing last argument to false)
        $cart->add_fee( __('Shipping weight fee', 'woocommerce'), $fee, true);
    }
}

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

此代码已经过测试并且可以运行

This code is tested and it works

从费用计算中减去最小的统一费率"金额，这样客户支付正确的价格.

The minimal 'Flat rate' amount is subtracted from the fee calculation, this way the customer pay the right price.
