Magento 2添加额外费用到订单总计

发布者: 360Magento

有时我们可能需要在Magento 2中为订单总额添加额外费用（手续费）。通常，订单总计包括小计，运费，税金和折扣，根据这些值计算总计。现在，如果我们想增加额外的费用，它将影响订单总额。在本文中，我们将指导您如何在没有任何问题的情况下为Magento 2订单额外收费。

在这里，我们将添加一个名为“处理费”的新订单总额，固定成本为10美元。

第1步：定义新模块，

在以下文件路径中创建module.xml文件以定义新模块，

<Magento_2_Root> /app/code/Alwayly/HandlingFee/etc/module.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Alwayly_HandlingFee" setup_version="1.0.0">
    </module>
</config>

接下来，在下面的文件路径中创建registration.php文件，

<Magento_2_Root> /app/code/Alwayly/HandlingFee/registration.php

<?php
\Magento\Framework\Component\ComponentRegistrar::register(
    \Magento\Framework\Component\ComponentRegistrar::MODULE,
    'Alwayly_HandlingFee',
    __DIR__
);

第2步： 在以下路径中创建文件sales.xml，

<Magento_2_Root> /app/code/Alwayly/HandlingFee/etc/sales.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Sales:etc/sales.xsd">
    <section name="quote">
        <group name="totals">
            <item name="handlingfee" instance="Alwayly\HandlingFee\Model\Quote\Address\Total\HandlingFee" sort_order="400"/>
        </group>
    </section>
</config>

步骤3：在以下路径中创建文件HandlingFee.php

<Magento_2_Root> /app/code/Alwayly/HandlingFee/Model/Quote/Address/Total/HandlingFee.php

<?php
namespace Alwayly\HandlingFee\Model\Quote\Address\Total;
class HandlingFee extends \Magento\Quote\Model\Quote\Address\Total\AbstractTotal
{
    /**
     * @var \Magento\Framework\Pricing\PriceCurrencyInterface
     */
    protected $_priceCurrency;
  
    /**
     * @param \Magento\Framework\Pricing\PriceCurrencyInterface $priceCurrency
     */
    public function __construct(
        \Magento\Framework\Pricing\PriceCurrencyInterface $priceCurrency
    ) {
        $this->_priceCurrency = $priceCurrency;
    }
  
    public function collect(
        \Magento\Quote\Model\Quote $quote,
        \Magento\Quote\Api\Data\ShippingAssignmentInterface $shippingAssignment,
        \Magento\Quote\Model\Quote\Address\Total $total
    ) {
        parent::collect($quote, $shippingAssignment, $total);
        $handlingFee = 10;
        $total->addTotalAmount('handlingfee', $handlingFee);
        $total->addBaseTotalAmount('handlingfee', $handlingFee);
        $quote->setHandlingFee($handlingFee);
        return $this;
    }
  
    public function fetch(
        \Magento\Quote\Model\Quote $quote,
        \Magento\Quote\Model\Quote\Address\Total $total
    ) {
        return [
            'code' => 'Handling_Fee',
            'title' => $this->getLabel(),
            'value' => 10
        ];
    }
  
    /**
     * get label
     * @return string
     */
    public function getLabel() {
        return __('Handling Fee');
    }
}

步骤4：在以下路径中创建文件checkout_cart_index.xml

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/layout/checkout_cart_index.xml

<?xml version="1.0"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="checkout.cart.totals">
            <arguments>
                <argument name="jsLayout" xsi:type="array">
                    <item name="components" xsi:type="array">
                        <item name="block-totals" xsi:type="array">
                            <item name="children" xsi:type="array">
                                <item name="handlingfee" xsi:type="array">
                                    <item name="component" xsi:type="string">Alwayly_HandlingFee/js/view/checkout/summary/handling-fee</item>
                                    <item name="sortOrder" xsi:type="string">20</item>
                                    <item name="config" xsi:type="array">
                                        <item name="handlingfee" xsi:type="string" translate="true">Handling Fee</item>
                                    </item>
                                </item>
                            </item>
                        </item>
                    </item>
                </argument>
            </arguments>
        </referenceBlock>
    </body>
</page>

步骤5：在同一路径中创建文件checkout_index_index.xml

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/layout/checkout_index_index.xml

<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceBlock name="checkout.root">
            <arguments>
                <argument name="jsLayout" xsi:type="array">
                    <item name="components" xsi:type="array">
                        <item name="checkout" xsi:type="array">
                            <item name="children" xsi:type="array">
                                <item name="sidebar" xsi:type="array">
                                    <item name="children" xsi:type="array">
                                        <item name="summary" xsi:type="array">
                                            <item name="children" xsi:type="array">
                                                <item name="totals" xsi:type="array">
                                                    <item name="children" xsi:type="array">
                                                        <item name="handlingfee" xsi:type="array">
                                                            <item name="component" xsi:type="string">Alwayly_HandlingFee/js/view/checkout/cart/totals/handling-fee</item>
                                                            <item name="sortOrder" xsi:type="string">20</item>
                                                            <item name="config" xsi:type="array">
                                                                <item name="template" xsi:type="string">Alwayly_HandlingFee/checkout/cart/totals/handling-fee</item>
                                                                <item name="title" xsi:type="string" translate="true">Handling Fee</item>
                                                            </item>
                                                        </item>
                                                    </item>
                                                </item>
                                                <item name="cart_items" xsi:type="array">
                                                    <item name="children" xsi:type="array">
                                                        <item name="details" xsi:type="array">
                                                            <item name="children" xsi:type="array">
                                                                <item name="subtotal" xsi:type="array">
                                                                    <item name="component" xsi:type="string">Magento_Tax/js/view/checkout/summary/item/details/subtotal</item>
                                                                </item>
                                                            </item>
                                                        </item>
                                                    </item>
                                                </item>
                                            </item>
                                        </item>

                </argument>
            </arguments>
        </referenceBlock>
    </body>
</page>

第6步：在路径上创建文件handling-fee.js

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/web/js/view/checkout/cart/totals/handling-fee.js

define(
    [
        'Alwayly_HandlingFee/js/view/checkout/summary/handling-fee'
    ],
    function (Component) {
        'use strict';
        return Component.extend({
            /**
             * @override
             */
            isDisplayed: function () {
                return true;
            }
        });
    }
);

步骤7：在以下路径中创建文件handling-fee.js .

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/web/js/view/checkout/summary/handling-fee.js

define(
    [
        'jquery',
        'Magento_Checkout/js/view/summary/abstract-total',
        'Magento_Checkout/js/model/quote',
        'Magento_Checkout/js/model/totals',
        'Magento_Catalog/js/price-utils'
    ],
    function ($,Component,quote,totals,priceUtils) {
        "use strict";
        return Component.extend({
            defaults: {
                template: 'Alwayly_HandlingFee/checkout/summary/handling-fee'
            },
            totals: quote.getTotals(),
               isDisplayedHandlingfeeTotal : function () {
               return true;
            },
            getHandlingfeeTotal : function () {
                var price = 10;
                return this.getFormattedPrice(price);
            }
        });
    }
);

步骤8：在以下路径中创建文件handling-fee.html

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/web/template/checkout/cart/totals/handling-fee.html

步骤9：在以下路径中创建文件handling-fee.html

<Magento_2_Root> /app/code/Alwayly/HandlingFee/view/frontend/web/template/checkout/summary/handling-fee.html

最后，您可以在购物车和结帐页面上看到额外的费用。
