Magento – Guest Wishlist in Magento 2

You can override the add to wishlist action in the wishlist controller and make it redirect to the referrer.

Override this method Mage_Wishlist_IndexController::addAction() and replace this:

$this->_redirect('*', array('wishlist_id' => $wishlist->getId())); 

with this:

$this->_redirectReferer()

To fix it we need to override Magento\Wishlist\Controller\Index\Add controller.

– add following line in module di.xml to tell magento to use our class instead of standard one.

Filename: Vendor/Module/etc/frontend/di.xml

<preference for="Magento\Wishlist\Controller\Index\Add" type="Vendor\Module\Controller\Index\Add">
</preference>

– create the class. Basically it duplicate original method, only $resultRedirect updated to use referer url

Filename: Vendor/Module/Controller/Index/Add.php

<?php
 
namespace Vendor\Module\Controller\Index;
 
use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\App\Action;
use Magento\Framework\Data\Form\FormKey\Validator;
use Magento\Framework\Exception\NotFoundException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Controller\ResultFactory;

class Add extends \Magento\Wishlist\Controller\Index\Add

    public function execute()
    {
        ...
        /* here comes the code from original controller  */
        ...
 
        $resultRedirect->setUrl($this->_redirect->getRefererUrl());
        return $resultRedirect;
    }
}
