此流程是在假设包裹重量和类型信息是管理员和运费是固定的情况下设置的。
步骤1：-创建etc/数据库架构. xml

<schema xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Setup/Declaration/Schema/etc/schema.xsd">
    <table name="sales_order" resource="default" engine="innodb" comment="sales_order">
        <column xsi:type="int" name="box_weight" default="0" comment="Box Weight" />
        <column xsi:type="varchar" name="box_type" nullable="false" length="255" comment="Box Type" />
    </table>
    <table name="sales_order_grid" resource="default" engine="innodb" comment="sales_order">
        <column xsi:type="int" name="box_weight" default="0" comment="Box Weight" />
        <column xsi:type="varchar" name="box_type" nullable="false" length="255" comment="Box Type" />
    </table>
</schema>

步骤2：创建模型/资源模型/订单/网格/集合. php文件

<?php

namespace Sunarc\Custom\Model\ResourceModel\Order\Grid;
 
use Magento\Framework\Data\Collection\Db\FetchStrategyInterface as CoreFetchStrategy;
use Magento\Framework\Data\Collection\EntityFactoryInterface as CoreEntityFactory;
use Magento\Framework\Event\ManagerInterface as CoreEventManager;
use Magento\Sales\Model\ResourceModel\Order\Grid\Collection as CoreSalesGrid;
use Psr\Log\LoggerInterface as Logger;
 

class Collection extends CoreSalesGrid
{
    /**
     * @param CoreEntityFactory $entityFactory
     * @param Logger            $logger       
     * @param CoreFetchStrategy $fetchStrategy
     * @param CoreEventManager  $eventManager 
     * @param string            $mainTable    
     * @param string            $resourceModel
     */
    public function __construct(
        CoreEntityFactory $entityFactory,
        Logger $logger,
        CoreFetchStrategy $fetchStrategy,
        CoreEventManager $eventManager,
        $mainTable = 'sales_order_grid',
        $resourceModel = \Magento\Sales\Model\ResourceModel\Order::class
    ) {
        parent::__construct($entityFactory, $logger, $fetchStrategy, $eventManager, $mainTable, $resourceModel);
    }
 
    protected function _renderFiltersBefore()
    {
        $joinTable = $this->getTable('sales_order');
        $this->getSelect()->joinLeft(
            $joinTable,
            'main_table.entity_id = sales_order.entity_id',
            ['box_weight','box_type']
        );
        parent::_renderFiltersBefore();
    }
}

第3步：现在，创建etc/di.xml文件以将自定义列数据添加到订单网格中。

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <preference for="Magento\Sales\Controller\Order\History" type="Sunarc\Custom\Controller\Order\History" />

    <type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">
        <arguments>
            <argument name="collections" xsi:type="array">
                <item name="sales_order_grid_data_source" xsi:type="string">Sunarc\Custom\Model\ResourceModel\Order\Grid\Collection</item>
            </argument>
        </arguments>
    </type>
    <type name="Sunarc\Custom\Model\ResourceModel\Order\Grid\Collection">
        <arguments>
            <argument name="mainTable" xsi:type="string">sales_order_grid</argument>
            <argument name="resourceModel" xsi:type="string">Magento\Sales\Model\ResourceModel\Order</argument>
        </arguments>
    </type>

</config>

步骤4：创建视图/管理html/用户界面组件/销售订单网格. xml

<?xml version="1.0" encoding="UTF-8"?>

<listing xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <columns name="sales_order_columns">

        <column name="box_weight">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="filter" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Parcel Weight</item>
                </item>
            </argument>
        </column>

        <column name="box_type">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="filter" xsi:type="string">text</item>
                    <item name="label" xsi:type="string" translate="true">Box Type</item>
                </item>
            </argument>
        </column>
    </columns>
</listing>

步骤5：-创建etc/事件. xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="sales_order_save_before">
        <observer name="weight" instance="Sunarc\Custom\Observer\Weight" />
    </event>
</config>

步骤6：创建Observer/Weight. php并编写自定义逻辑

<?php

namespace Sunarc\Custom\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Quote\Model\QuoteFactory;

class Weight implements ObserverInterface
{

    public function __construct(QuoteFactory $quoteFactory)
    {
        $this->quoteFactory = $quoteFactory;
    }
    /**
     * Below is the method that will fire whenever the event runs!
     *
     * @param Observer $observer
     */
    public function execute(Observer $observer)
    {

        //WRITE YOUR CUSTOM LOGIC HERE
        $order = $observer->getEvent()->getOrder();

        if ($order->getData('weight') == 1) {
            $order->setData('box_weight', 5); // Assumed wight of small parcel
            $order->setData('box_type', 'Small');
        } elseif ($order->getData('weight') > 1 && $order->getData('weight') <= 2) {
            $order->setData('box_weight', 7); // Assumed wight of Medium parcel
            $order->setData('box_type', 'Medium');
        } else {
            $order->setData('box_weight', 10);  // Assumed wight of Large parcel
            $order->setData('box_type', 'Large');
        }
    }
}
