Magento 2 - Cart empty after successful payment

Question

I have a custom payment method, after successful payment; payment page return to a controller where it updates order status and truncate current cart items like this:

$this->quote->load($orders->getQuoteId());

$this->quote->setReservedOrderId(null);
$this->quote->setIsActive(true);
$this->quote->removePayment();
$this->quote->save();

$this->cart->truncate();
$this->cart->saveQuote();

Where $this->quote is object of Magento\Quote\Model\Quote
and $this->cart is object of Magento\Checkout\Model\Cart

The cart is truncating properly, but the cart summery count is still appearing on header, and when I go to view cart, it is showing empty cart with previous order total, as shown in image below

My question is, how can I fully empty my cart data after successful payment?

Answer 1

You may try to use checkout session Model to clear quote data (i.e Magento\Checkout\Model\Session.php ).

Update your payment module controller code as follow.

I assume your custom payment module controller file name is MypaymentController.php

classs MypaymentController    extends \Magento\Framework\App\Action\Action
{

    /**
     * @var \Magento\Checkout\Model\Session
     */
    private $checkoutSession;


      public function __construct(
        ........................
        ........................
        SessionManagerInterface $checkoutSession,
        ........................
        ........................
      ){

        ........................
        $this->checkoutSession = $checkoutSession;
        ........................
      }



    public function execute()
    {
       ........................
       $this->_checkoutSession->clearQuote();
       $this->_checkoutSession->clearStorage();
       $this->_checkoutSession->restoreQuote();
       ........................

    }    

}

** Note:**

If your payment module controller already injected the Checkout Session Model (i.e \Magento\Checkout\Model\Session) then do not reinject Session Model, just try to use the functions below in your controller code block.

$this->_checkoutSession->clearQuote();
$this->_checkoutSession->clearStorage();
$this->_checkoutSession->restoreQuote();

You need to do following things.

1. create sections.xml at the following location with the code.

app\code\Vendor\Extension\etc\frontend\sections.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Customer:etc/sections.xsd">
    <action name="module/controller/action">
        <section name="cart"/>
        <section name="checkout-data"/>
    </action>
</config>

NOTE : replace module/controller/action with your above controller action path.
