Magento2 : How to get last order id in payment module template file

Question

I am creating a custom payment method module in magento2.

On order place redirecting to to my request controller from script. In request controller I have below code :

...
$resultPage = $this->_pageFactory->create();
$resultPage->addHandle('custom_request_index');
return $resultPage;
...

In xml file added template file form.phtml and it is loading on the page.

All are working but I am trying to get last order id in form.phtml file as below :

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$checkout_session = $objectManager->get('\Magento\Checkout\Model\Session');
$incrementId = $checkout_session->getLastRealOrderId();
echo $incrementId;

But above code returning nothing. But when I try to log same code in request controller then it returns correct order id.

I have also tried to add a function in block file to get order id in template file like $block->getLastOrder() but this function also returning nothing, while other functions in block file working properly.

Why this is happening? How to get last order id in form.phtml file?

• Yogesh Karodiya: It may be caching issue because block and template has been cached.
• Vinaya Maheshwari: No, I tried to echo some different string every time on form.phtml, and that is showing on page.
• Keyur Shah: @YogeshKarodiyais right sometimes it creates an issue because of cache but you can also try to $objectManager->create method instead of $objectManager->get method so it fetches new object for you. This is blind shoot
• Vinaya Maheshwari: @YogeshKarodiya, Now changes not reflecting on frontend, I tried php bin/magento cache:clean, php bin/magento cache:flush, php bin/magento setup:di:compile, php bin/magento setup:static-content:deploy commands, but still changes not reflecting on frontend. How to remove cache?
• Yogesh Karodiya: try to get $incrementId into the controller and pass it to the block from controller.

Answer 1

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$checkout_session = $objectManager->get('Magento\Checkout\Model\Session');
$order = $checkout_session->getLastRealOrder();
$orderId= $order->getEntityId();
echo $order->getIncrementId();

It can help you There is a mistake in 2nd line

$checkout_session = $objectManager->get('Magento\Checkout\Model\Session');

• Himanshu Pareta: @Piyush, Actually I posted this via cell phone so it was not well arranged
• Vinaya Maheshwari: please check my above comments, now changes in form.phtml also not reflecting on production server.
