How to redirect customer to cart in beforeSavePaymentInformationAndPlaceOrder

How to redirect customer to cart in beforeSavePaymentInformationAndPlaceOrder

In my plugin i have added an call to an remote api call. And if there is an error the customer needs to be redirected back to the cart and show the error.

I have this code but it doesnt work as expected.

 

try {
            $this->_stock->reserveRemoteStock();
        } catch (\Magento\Framework\Exception\LocalizedException $e) {
            if ($this->_session->getUseNotice(true)) {
                $this->_messageManager->addNotice($e->getMessage());
            } else {
                $messages = array_unique(explode("\n", $e->getMessage()));
                foreach ($messages as $message) {
                    $this->_messageManager->addError($message);
                }
            }

            $url = $this->_session->getRedirectUrl(true);
            if ($url) {
                return $this->resultRedirectFactory->create()->setUrl($url);
            } else {
                $cartUrl = $this->_objectManager->get('Magento\Checkout\Helper\Cart')->getCartUrl();
                return $this->resultRedirectFactory->create()->setUrl($this->_redirect->getRedirectUrl($cartUrl));
            }
        } catch (\Exception $exc) {
            throw new LocalizedException(__($exc->getMessage()));
        }

Thank you for your help.

Instead return... throw an exception like:

throw new \Magento\Framework\Exception\CouldNotSaveException(
    __('Please agree to all the terms and conditions before placing the order.')
);

Also, I saw that in your lines like:

return $this->resultRedirectFactory...

...are missing ->sendResponse(); at the end of line.

Re: How to redirect customer to cart in beforeSavePaymentInformationAndPlaceOrder

Thank you for your answer, when I throw an exception I dont get redirected, I stay at the last step of the checkout (payment). The ->sendResponse(); was the trick of redirecting. But now all error messages are not displayed.

 

I Thought I could use the \Magento\Framework\Message\ManagerInterface for that. Or I'm doing something wrong there.
