Hi, My requirement was to add a "subscribe to the newsletter" checkbox at one-page checkout page (below "terms and condition" checkbox). All the things are fine except for 2 issues:
- The user MUST NOT be subscribed if he unchecks the checkbox. So dont know how to get the value of that custom checkbox placed on checkout page (for this I used Layoutprocessor to put the checkbox).
- For the very first time when the user mail is not there in DB for newsletter subscription and I hit the place order button, the page is broken but if the email is already there in DB (under newsletter subscribers in admin) and the user places the order and don't uncheck the checkbox, all fine. I played with the observer checkout_onepage_controller_success_action (don't know why sales_order_place_before and sales_order_place_after not working), code below:
<?php
/**
*
* Register to Newsletter during checkout process
*/
namespace <Mynamespace>\<Mymodule>\Observer\Sales;
use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;
use Magento\Newsletter\Model\Subscriber;
use Magento\Framework\App\RequestInterface;
use Psr\Log\LoggerInterface;
class OrderPlaceBefore implements ObserverInterface
{
protected $_subscriber;
protected $_request;
protected $_logger;
/**
* @param Subscriber $subscrbr
* @param RequestInterface $request
* @param LoggerInterface $logger
*/
public function __construct(
Subscriber $subscrbr,
RequestInterface $request,
LoggerInterface $logger
) {
$this->_subscriber = $subscrbr;
$this->_request = $request;
$this->_logger = $logger;
}
/**
* Subscribe to newsletters if customer checked the checkbox
*
* @param \Magento\Framework\Event\Observer $observer
* @return $this
*/
public function execute(\Magento\Framework\Event\Observer $observer)
{
$order = $observer->getEvent()->getOrder();
$customerEmail = $order->getCustomerEmail();
try {
**//Here the conditions should go, if the checkbox is checked then only subscribe to newsletter otherwise not
//How to get custom checkbox value after order placement? Tried with $this->_request->getpost() but not working, returning an empty array**
$subscriber = $this->_subscriber->loadByEmail($customerEmail);
if (!$subscriber->getId()) {
//at this line, first time for non-existing email, the page is broken, not sure WHY??
$this->_subscriber->subscribe($customerEmail);
}
} catch (\Exception $e) {
$this->_logger->critical($e->getMessage() . ' from Mynamespace-Mymodule ' . $customerEmail);
}
return $this;
}
}
Code for Layoutprocessor file

public function process($jsLayout)
{
$jsLayoutSubscribe = [

]
]
];
$jsLayout = array_merge_recursive($jsLayout, $jsLayoutSubscribe);
return $jsLayout;
}
}
Not sure where I am wrong? Can you please guide? Thanks in advance.
