Hello @chathuramk,
As you mentioned your problem, I think default Magento sends the confirmation mail automatically once the order is placed. But it does not have the functionality of sending email after getting successful payment from third-party gateways. But you can try this below solution.
First, you need to bind Magento 2 observer with an event of checkout_onepage_controller_success_action.
Please make sure that the order confirmation email is not sent twice, So you have to create a simple method isEnable() using OrderIdentity.php.
First, you have to register the event under events.xml using below code
[Package_Name]\[Module_Name]\etc\frontend\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="checkout_onepage_controller_success_action">
<observer name="checkout_onepage_controller_success_action_sendmail" instance="[Package_Name]\[Module_Name]\Observer\SendMailOnOrderSuccess" />
</event>
</config>
when the event is registered, you need to create an Observer class in the below file.
[Package_Name]\[Module_Name]\Observer\SendMailOnOrderSuccess.php
<?php
namespace [Package_Name]\[Module_Name]\Observer;
use Magento\Framework\Event\ObserverInterface;
class SendMailOnOrderSuccess implements ObserverInterface
{
/**
* @var \Magento\Sales\Model\OrderFactory
*/
protected $orderModel;
/**
* @var \Magento\Sales\Model\Order\Email\Sender\OrderSender
*/
protected $orderSender;
/**
* @var \Magento\Checkout\Model\Session $checkoutSession
*/
protected $checkoutSession;
/**
* @param \Magento\Sales\Model\OrderFactory $orderModel
* @param \Magento\Sales\Model\Order\Email\Sender\OrderSender $orderSender
* @param \Magento\Checkout\Model\Session $checkoutSession
*
* @codeCoverageIgnore
*/
public function __construct(
\Magento\Sales\Model\OrderFactory $orderModel,
\Magento\Sales\Model\Order\Email\Sender\OrderSender $orderSender,
\Magento\Checkout\Model\Session $checkoutSession
)
{
$this->orderModel = $orderModel;
$this->orderSender = $orderSender;
$this->checkoutSession = $checkoutSession;
}
/**
* @param \Magento\Framework\Event\Observer $observer
* @return void
*/
public function execute(\Magento\Framework\Event\Observer $observer)
{
$orderIds = $observer->getEvent()->getOrderIds();
if(count($orderIds))
{
$this->checkoutSession->setForceOrderMailSentOnSuccess(true);
$order = $this->orderModel->create()->load($orderIds[0]);
$this->orderSender->send($order, true);
}
}
}Once you complete adding observer code, an email will be sent to customers on successful order payment.
If you want to avoid order duplication Email, you can create a plugin using the di.xml file.
[Package_Name]\[Module_Name]\etc\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\Sales\Model\Order\Email\Container\OrderIdentity">
<plugin name="change_is_enable_method" type="\[Package_Name]\[Module_Name]\Plugin\Sales\Order\Email\Container\OrderIdentityPlugin"/>
</type>
</config>At last, you need to create another file with ‘di.xml’ that is OrderIdentityPlugin.php to avoid email duplication.
[Package_Name]\[Module_Name]\Plugin\Sales\Order\Email\Container\ OrderIdentityPlugin.php
<?php
namespace [Package_Name]\[Module_Name]\Plugin\Sales\Order\Email\Container;
class OrderIdentityPlugin
{
/**
* @var \Magento\Checkout\Model\Session $checkoutSession
*/
protected $checkoutSession;
/**
* @param \Magento\Checkout\Model\Session $checkoutSession
*
* @codeCoverageIgnore
*/
public function __construct(
\Magento\Checkout\Model\Session $checkoutSession
)
{
$this->checkoutSession = $checkoutSession;
}
/**
* @param \Magento\Sales\Model\Order\Email\Container\OrderIdentity $subject
* @param callable $proceed
* @return bool
*/
public function aroundIsEnabled(\Magento\Sales\Model\Order\Email\Container\OrderIdentity $subject, callable $proceed)
{
$returnValue = $proceed();
$forceOrderMailSentOnSuccess = $this->checkoutSession->getForceOrderMailSentOnSuccess();
if(isset($forceOrderMailSentOnSuccess) && $forceOrderMailSentOnSuccess)
{
if($returnValue)
$returnValue = false;
else
$returnValue = true;
$this->checkoutSession->unsForceOrderMailSentOnSuccess();
}
return $returnValue;
}
}Hope this will help you.
