How to add a custom column to the order grid in Magento 2?

How to add a new column to the Magento 2 order grid?

To add a new Magento 2 column to the order grid, you need to create and register a custom module. Then, create the Resource Model using the  _renderFiltersBefore method. After this, you need to develop a UI component. The detailed step-by-step guide on how to add a field to order in Magento 2 with code examples you can find in the article below.

Let’s start.

Warning: all the code pieces presented in this article are simple examples that you need to customize according to your business needs.

Method 1. Add a column programmatically

In the Magento order grid to add a column, you need to create a custom plugin following this step-by-step guide. 

Step 1. Register the module by creating the registration.php file in the app/code/Amasty/Testgrid/ with the following code:

<?php

\Magento\Framework\Component\ComponentRegistrar::register(

    \Magento\Framework\Component\ComponentRegistrar::MODULE,

    'Amasty_Testgrid',

    __DIR__

);

Step 2. Next, create the app/code/Amasty/Testgrid/etc/module.xml file. It controls the module installation and updates.

<?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="Amasty_Testgrid" setup_version="1.0.0">

    </module>

</config>

Step 3. Then, what you need to do to add a column to the Magento 2 order grid is the Resource Model creation. For this, create Collection.php in the app/code/Amasty/Testgrid/Model/ResourceModel/Order/Grid/ folder. It may look like this:

<?php

namespace Amasty\Testgrid\Model\ResourceModel\Order\Grid;

use Magento\Framework\Data\Collection\Db\FetchStrategyInterface as FetchStrategy;

use Magento\Framework\Data\Collection\EntityFactoryInterface as EntityFactory;

use Magento\Framework\Event\ManagerInterface as EventManager;

use Magento\Sales\Model\ResourceModel\Order;

use Magento\Sales\Model\ResourceModel\Order\Grid\Collection as OrderGridCollection;

use Psr\Log\LoggerInterface as Logger;

class Collection extends OrderGridCollection

{

    public function __construct(

        EntityFactory $entityFactory,

        Logger $logger,

        FetchStrategy $fetchStrategy,

        EventManager $eventManager,

        $mainTable = 'sales_order_grid',

        $resourceModel = Order::class

    ) {

        parent::__construct($entityFactory, $logger, $fetchStrategy, $eventManager, $mainTable, $resourceModel);

    }

    protected function _renderFiltersBefore() {

        $joinTable = $this->getTable('sales_order');

        $this->getSelect()->joinLeft(

            ['sales_order_table' => $joinTable],

            'main_table.entity_id = sales_order_table.entity_id',

            ['discount_amount'] 
        );
        parent::_renderFiltersBefore();
    }
}

In the  _renderFiltersBefore method, you can add the columns that you want, for example, we’ve used the discount_amount column. In this array, you can pass as many parameters from the sales_order table as you like. Also, here you can join the other one or several tables to use the needed parameters for the order.
Step 4. Then we need to create a UI component file app/code/Amasty/Testgrid/view/adminhtml/ui_component/sales_order_grid.xml with the following code:
<?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="discount_amount" class="Magento\Sales\Ui\Component\Listing\Column\PurchasedPrice">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="filter" xsi:type="string">textRange</item>
                    <item name="label" xsi:type="string" translate="true">Discount Amount</item>
                </item>
            </argument>
        </column>
    </columns>
</listing>

This file is responsible for columns on the grid. You can add other column elements, but don’t forget to use the resource model.
Step 5. As a final step adding a custom column to Magento 2 order grid, return to app/code/Amasty/Testgrid/etc/ and create di.xml:
<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
    <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">Amasty\Testgrid\Model\ResourceModel\Order\Grid\Collection</item>
            </argument>
        </arguments>
    </type>
    <type name="Amasty\Testgrid\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>

In this file, we define where we want to apply our changed collection. In the same way, you can add a column to any grid in your Magento 2, say, to the customer grid.
