Restore quote in magento2

Question

I have canceled the current order like

use Magento\Sales\Model\OrderFactory;
$order = $this->orderFactory->create()->loadByIncrementId($order->getIncrementId());
$order->cancel()->save();

After that, create a new quote and assign the quote item using this link.

It's working fine. But when the ordered product has 1 qty, it returned the "product is out of stock" message.

How to resolve that.

How to restore the quote for payment failure.

Thanks.

Answer 1

You need to debug the $cartItem->setQty($qty) Function, May be this function is not getting 1 qty when you entered.

Please check once function parameter Value or set $cartItem->setQty($qty = 1) default value as one.

Restore the quote for payment failure.

in YourIcancelAction() Or failureAction();

Add below code:

if (\Magento\Checkout\Model\Session::restoreQuote()->getLastRealOrderId()) {
    if ($lastQuoteId = \Magento\Checkout\Model\Session::restoreQuote()->getLastQuoteId()) {
        $quote = \Magento\Quote\Model\ResourceModel\Quote\Item->load($lastQuoteId);
        $quote->setIsActive(true)->save();
    }
}
