How to redirect to cart after login using an observer in Magento 2

Question

By default when guest checkout is disabled in Magento 2.

No matter where a user is trying to go they're forwarded to their account after login, including if they've already added items to their cart and have clicked checkout in their mini-cart.

I feel like this is a hindrance to the sales pipeline.

I'm attempting to make an observer that redirects a user to their cart/checkout if that was their intended purpose.

Even if they need to create an account in between.

Currently, I'm working on step one. Simply redirecting someone to their cart after logging in. The problem is that it seems none of the various redirect techniques have worked except for those that use exit(); or die(); in their methods.

In the notes of these suggestions, there are warnings not to use these functions as it interrupts the application.

Is there a good way to redirect a customer after they've logged in? Here is what I have so far:

=> etc/events.xml:

<?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="customer_login">
        <observer name="made_up_name_seems_to_work" instance="Vendor\NameSpace\Observer\Redirect" />
    </event>
</config>

=> Observer/Redirect.php:

<?php

namespace Vendor\NameSpace\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class Redirect implements \Magento\Framework\Event\ObserverInterface
{

    protected $_responseFactory;
    protected $_url;
    protected $_session;

    public function __construct(
        \Magento\Customer\Model\Session $session,
        \Magento\Framework\App\ResponseFactory $responseFactory,
        \Magento\Framework\UrlInterface $url
    ) {
        $this->_session = $session;
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {

        $isCustomerLoggedIn = $this->_session->isLoggedIn();

        if ($isCustomerLoggedIn) {

            $event = $observer->getEvent();
            $CustomRedirectionUrl = $this->_url->getUrl('checkout/cart');
            $this->_responseFactory->create()->setRedirect($CustomRedirectionUrl)->sendResponse();
            \Magento\Framework\App\ObjectManager::getInstance()->get('Psr\Log\LoggerInterface')->debug('URL: ' . $CustomRedirectionUrl);
            return $this;
        }
    }
}

The above redirect isn't working at all even with Exit() or die() however, it reflects where I'm at currently.

Is there a good(or proper) way to redirect from this observer?

Answer 1

customer_login may not be a proper event for this.

But it will every useful when you will login from customer/account/login.

As my suggestion,instead of using customer_login use customer_data_object_login.

In best practices,instead of forceful redirection by your code.

can use

$this->_session->setBeforeAuthUrl($CustomRedirectionUrl);

Bcoz at magento, redirection after login is depend on

$this->_session->getBeforeAuthUrl()

field, So, when you done successful login then set redirection url to this session variable is the best idea/solution .

Observer.php:

<?php
namespace Vendor\NameSpace\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class Redirect implements \Magento\Framework\Event\ObserverInterface
{

    protected $_responseFactory;
    protected $_url;
    protected $_session;

    public function __construct(
        \Magento\Customer\Model\Session $session,
        \Magento\Framework\App\ResponseFactory $responseFactory,
        \Magento\Framework\UrlInterface $url
    ) {
        $this->_session = $session;
        $this->_responseFactory = $responseFactory;
        $this->_url = $url;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {

        $isCustomerLoggedIn = $this->_session->isLoggedIn();

        if ($isCustomerLoggedIn) {
            $event = $observer->getEvent();
            $CustomRedirectionUrl = $this->_url->getUrl('checkout/cart');
            $this->_session->setBeforeAuthUrl($CustomRedirectionUrl);
            return $this;
        }
    }
}
