Is there any way to store checkout custom field data to checkout session? If possible how can I retrieve data?

Created an event

<?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_observer" instance="MageplazaHelloWorldObserverTestObserver" />
 </event>
</config>

Observer code-

 <?php
 namespace OyeDeliverydateModelObserver;
 use MagentoFrameworkEventObserver as EventObserver;
 use MagentoFrameworkEventObserverInterface;

 /**
 * Class SaveDeliveryDateToOrderObserver
 * @package OyeDeliverydateModelObserver
 */
 class SaveDeliveryDateToOrderObserver implements ObserverInterface
 
 /**
 * @var MagentoFrameworkObjectManagerInterface
 */
 protected $_objectManager;

 /**
 * @param MagentoFrameworkObjectManagerInterface $objectmanager
 */
 public function __construct(MagentoFrameworkObjectManagerInterface $objectmanager)
 
 $this->_objectManager = $objectmanager;
 

 /**
 * @param EventObserver $observer
 * @return $this
 */
 public function execute(EventObserver $observer)
 
 $order = $observer->getOrder();
 $quoteRepository = $this->_objectManager->create('MagentoQuoteModelQuoteRepository');
 $quote = $quoteRepository->get($order->getQuoteId());
 $order->setDeliveryDate( $quote->getDeliveryDate() );
 //echo $quote->getDeliveryDate();
 // exit();

 

 

In the observer last line I tried to echo deliverydate custom field value
using echo $quote->getDeliveryDate(); but not getting that value. Can I use session to store these custom checkout field value?

To know about use of checkout session you should check below link -

http://blog.chapagain.com.np/magento-2-set-unset-get-session/

for more specific answer please share the exact event or requirement when you want to use checkout session.

protected $_checkoutSession;
public function __construct(
 ....
 public function __construct(
 MagentoCheckoutModelSession $checkoutSession
) 

 $this->_checkoutSession = $checkoutSession;


public function getCheckoutSession() 

 return $this->_checkoutSession;

You set a value :

$this->getCheckoutSession()->setVarValue('someValueHere');

You get a value :

$this->getCheckoutSession()->getVarValue(); //someValueHere

Then you unset the value :

$this->getCheckoutSession()->unsVarValue();
