How to Add New Total to Email in Magento 2

Hello guys! The tutorial today will help the Magento 2 merchants to add the new total block into order email by themselves. As it is necessary when sending your customers the verified email to confirm their purchasing on your store. And your company will be even more reliable when informing your shoppers with the total purchase orders.

However, Magento 2 does not support the available feature of adding the new total block into the confirmation email or email of invoice. Hence, let’s follow the guidance in this post to setup the total block into the order email before sending it to your customers.

Add New Total to Email in 2 Steps

Step 1: Generate the file: sales_email_order_items.xml

  • Create the file: sales_email_order_items.xml in the etc/frontend folder:
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
   <body>
       <referenceBlock name="order_totals">
           <block class="Mageplaza\HelloWorld\Block\Order\Totals" name="new.order.totals" />
       </referenceBlock>
   </body>
</page>

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
   <body>
       <referenceBlock name="order_totals">
           <block class="Mageplaza\HelloWorld\Block\Order\Totals" name="new.order.totals" />
       </referenceBlock>
   </body>
</page>
  • Now the block new.order.totals have been inserted to the order_totals when sending the email.

Step 2: Create the block new.order.totals

  • Create the block new.order.totals to show the information for the new total.
  • Create the file : Mageplaza\HelloWorld\Block\Order\Totals.php
  • In the initTotals() function, insert your logic to calculate the amount which you want to show in the email.
<?php
namespace Mageplaza\HelloWorld\Block\Order;
class Totals extends \Magento\Framework\View\Element\AbstractBlock
{
   public function initTotals()
   {
       $orderTotalsBlock = $this->getParentBlock();
       $order = $orderTotalsBlock->getOrder();
       if ($order->getNewTotalAmount() > 0) {
           $orderTotalsBlock->addTotal(new \Magento\Framework\DataObject([
               'code'       => 'new_total',
               'label'      => __('New Total'),
               'value'      => $order->getNewTotalAmount(),
               'base_value' => $order->getNewTotalBaseAmount(),
           ]), 'subtotal');
       }
   }
}
  • Save the file.

Wrap up
