Send Order Email to Custom email IDs when order by specific payment method

Question

I have added one field in the configuration to add email IDS. When the order is placed by some payment method for example, "Cash on Delivery" I want to send New order email to those email IDs of the custom field.

I'm not understanding how to achieve this.

Please help me with this or give me some suggestions.

Answer 1

Yes, you can achieve this requirement by few customizations

Step1: Create a class which has setter and get method and using class you can pass an email to Magento\Sales\Model\Order\Email\Container\OrderIdentity:getEmailCopyTo.

Code

<?php


namespace DevAmitBera\OrderEmail\Model;


class OrderEmail
{
    private $extraOrderEmailId;

    public function set($email)
    {
        $this->extraOrderEmailId = $email;
    }
    public function get()
    {
        return $this->extraOrderEmailId;
    }
}

Step2: Create an observer on email_order_set_template_vars_before event and your custom email $extraOrderEmailId of DevAmitBera\OrderEmail\Model\Order\OrderEmail.

Code

<?php


namespace DevAmitBera\OrderEmail\Observer;


use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class EmailOrderSetTemplateVarsBefore implements ObserverInterface
{
    /**
     * @var \Ronin\ErpOrder\Model\OrderEmail
     */
    private $orderEmail;

    public function __construct(
        \Ronin\ErpOrder\Model\OrderEmail $orderEmail
    ){
        $this->orderEmail = $orderEmail;
    }

    /**
     * @inheritDoc
     */
    public function execute(Observer $observer)
    {
        $transportObject = $observer->getEvent()->getData('transportObject');
        if($transportObject->getData('order')){
            $order = $transportObject->getData('order');
            $payment = $order->getPayment();


           if($payment->getMethod() == 'cashondelivery'){
                $this->orderEmail->set(['[email protected]','[email protected]']);
           }

        }
    }
}

Step3: Create a plugin on Magento\Sales\Model\Order\Email\Container\OrderIdentity::getEmailCopyTo

and then using after Plugin on the method getEmailCopyTo

and your Custom email to order list

Code

<?php


namespace DevAmitBera\OrderEmail\Plugin\Order\Email\Container;


class OrderIdentity
{
    /**
     * @var \Ronin\ErpOrder\Model\OrderEmail
     */
    private $orderEmail;

    public function __construct(
        \Ronin\ErpOrder\Model\OrderEmail $orderEmail
    ){
        $this->orderEmail = $orderEmail;
    }

    public function afterGetEmailCopyTo(
        \Magento\Sales\Model\Order\Email\Container\OrderIdentity $subject,
        $result
    ){

        $additionalEmailId = $this->orderEmail->get();

        if(($additionalEmailId === null) || (!$additionalEmailId) || empty($additionalEmailId)){
            return $result;
        }

        if (!empty($result) && is_array($result)){

            foreach($additionalEmailId as $eachEmail){
               $result[] = (string) $eachEmail;     
            }

            return $result;
        }else{
            return [$additionalEmailId];
        }
    }

}

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="set_extra_params_to_order"
                  instance="DevAmitBera\OrderEmail\Observer\EmailOrderSetTemplateVarsBefore" />
    </event>
</config>

di.xml for plugin definition

<?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\Sales\Model\Order\Email\Container\OrderIdentity">
        <plugin name="add_addition_class_to"
                type="DevAmitBera\OrderEmail\Plugin\Order\Email\Container\OrderIdentity"
                sortOrder="1" disabled="false" />
    </type>
</config>
