Magento 2 override add wishlist controller?

Question

I tried to override add wishlist controller from the custom module but it's not working.

app/code/Demo/Wishlist/etc/frontend/di.xml

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> 
<preference for="Magento\Wishlist\Controller\Index\Add" type="Demo\Wishlist\Controller\Index\Add"/>
</config>

app/code/Demo/Wishlist/Controller/Index/Add.php

 <?php
namespace Demo\Wishlist\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;
/**
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 */
class Add extends \Magento\Wishlist\Controller\Index\Add
{
 /**
 * @var \Magento\Wishlist\Controller\WishlistProviderInterface
 */
 protected $wishlistProvider;
 /**
 * @var \Magento\Customer\Model\Session
 */
 protected $_customerSession;
 /**
 * @var ProductRepositoryInterface
 */
 protected $productRepository;
 /**
 * @var Validator
 */
 protected $formKeyValidator;
 /**
 * @param Action\Context $context
 * @param \Magento\Customer\Model\Session $customerSession
 * @param \Magento\Wishlist\Controller\WishlistProviderInterface $wishlistProvider
 * @param ProductRepositoryInterface $productRepository
 * @param Validator $formKeyValidator
 */
 public function __construct(
 Action\Context $context,
 \Magento\Customer\Model\Session $customerSession,
 \Magento\Wishlist\Controller\WishlistProviderInterface $wishlistProvider,
 ProductRepositoryInterface $productRepository,
 Validator $formKeyValidator
 ) {
 $this->_customerSession = $customerSession;
 $this->wishlistProvider = $wishlistProvider;
 $this->productRepository = $productRepository;
 $this->formKeyValidator = $formKeyValidator;
 parent::__construct($context, $customerSession, $wishlistProvider, $productRepository, $formKeyValidator);
 }
 /**

 * @return \Magento\Framework\Controller\Result\Redirect
 * @throws NotFoundException
 * @SuppressWarnings(PHPMD.CyclomaticComplexity)

 */
 public function execute()
 {
 echo "From custom module calling";
 exit;
 }
}

I have followed the below reference link in the clean default magento2.3.2 EE but no luck.

Can any one know the reason what I was missed here?

Answer 1

EE Version should using MultipleWishlist instead of wishlist, so you should override MultipleWishlist

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

Answer 2

You have to pass dependency to parent class in construct of child controller.

Please use below code

 public function __construct(
 Action\Context $context,
 \Magento\Customer\Model\Session $customerSession,
 \Magento\Wishlist\Controller\WishlistProviderInterface $wishlistProvider,
 ProductRepositoryInterface $productRepository,
 Validator $formKeyValidator
 ) {
 $this->_customerSession = $customerSession; 
 $this->wishlistProvider = $wishlistProvider;
 $this->productRepository = $productRepository;
 $this->formKeyValidator = $formKeyValidator;
 parent::__construct($context, $customerSession, $wishlistProvider, $productRepository, $formKeyValidator);
 }

Try to use below code in your di.xml file

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">
 <preference for="Magento\Wishlist\Controller\Index\Add" type="Vendor\Module\Controller\Wishlist\Add"/>
</config>

app/code/Vendor/Module/Controller/Wishlist/Add.php

Content for this file is..

<?php
namespace Vendor\Module\Controller\Wishlist;
use Magento\Catalog\Api\ProductRepositoryInterface;
use Magento\Framework\App\Action;
use Magento\Framework\App\Action\HttpPostActionInterface;
use Magento\Framework\Data\Form\FormKey\Validator;
use Magento\Framework\Exception\NotFoundException;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Controller\ResultFactory;
/**
 * @SuppressWarnings(PHPMD.CouplingBetweenObjects)
 */
class Add extends \Magento\Wishlist\Controller\Index\Add
{
 /**
 * @var \Magento\Wishlist\Controller\WishlistProviderInterface
 */
 protected $wishlistProvider;
 /**
 * @var \Magento\Customer\Model\Session
 */
 protected $_customerSession;
 /**
 * @var ProductRepositoryInterface
 */
 protected $productRepository;
 /**
 * @var Validator
 */
 protected $formKeyValidator;
 /**
 * @param Action\Context $context
 * @param \Magento\Customer\Model\Session $customerSession
 * @param \Magento\Wishlist\Controller\WishlistProviderInterface $wishlistProvider
 * @param ProductRepositoryInterface $productRepository
 * @param Validator $formKeyValidator
 */
 public function __construct(
 Action\Context $context,
 \Magento\Customer\Model\Session $customerSession,
 \Magento\Wishlist\Controller\WishlistProviderInterface $wishlistProvider,
 ProductRepositoryInterface $productRepository,
 Validator $formKeyValidator
 ) {
 $this->_customerSession = $customerSession;
 $this->wishlistProvider = $wishlistProvider;
 $this->productRepository = $productRepository;
 $this->formKeyValidator = $formKeyValidator;
 parent::__construct($context, $customerSession, $wishlistProvider, $productRepository, $formKeyValidator);
 }
 /**
 * Adding new item
 *
 * @return \Magento\Framework\Controller\Result\Redirect
 * @throws NotFoundException
 * @SuppressWarnings(PHPMD.CyclomaticComplexity)
 * @SuppressWarnings(PHPMD.NPathComplexity)
 * @SuppressWarnings(PHPMD.UnusedLocalVariable)
 */
 public function execute()
 {
 echo "From custom module wishlist has been calling";
 exit; 
 }
}
