what is the problem? email template

Answer 1

Please use the email_order_set_template_vars_before event, which allows you to send custom parameters to your order email. Check the working code below:

app/code/Magetrend/Custom/etc

events.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="email_order_set_template_vars_before">
     <observer name="mtemail_custom_var" instance="Magetrend\Custom\Observer\CustomVar"/>
 </event>
</config>

app/code/Magetrend/Custom/Observer

CustomVar.php

<?php

namespace Magetrend\Custom\Observer;

class CustomVar implements \Magento\Framework\Event\ObserverInterface
{
    protected $order;

    public function __construct(
        \Magento\Sales\Model\Order $order
    )
    {
        $this->order = $order;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $transport = $observer->getTransport();
        $orderId = $observer->getTransport()->getOrderId();
        $order = $this->order->load($orderId);
        $allVisibleItems = $order->getAllVisibleItems();
        $totalItemsCount = count($order->getAllVisibleItems());
        $i = 0;
        foreach ($allVisibleItems as $item)
        {
            if($i == 0){
                $productName = $item->getProduct()->getName();
                break;
            }
            $i++;
        }

        if($totalItemsCount > 1){
            $remainingItems = $totalItemsCount - 1;
            $transport['itemName'] = $productName.' and '.$remainingItems .' more products';
        }else{
            $transport['itemName'] = $productName;
        }
    }
}

Add the following line to the email template:

<h3>{{var itemName|raw}}</h3>

Note: After updating and adding the above code, please revise your order email template. Ensure that you are checking the correct order email template. Add a static value and verify if the order email is displaying correctly or not.
