Magento 2 Wishlist allows users to add products to their favorites, which will save time for the next purchases. Also, the wishlists can also be shared with anyone via email.

This article will guide you on how to add a product to the wishlist in Magento 2 programmatically.

How to Add Product to Wishlist

To add a product to a wishlist, we need two parameters: product object and customer id.

  • Product Object: can be obtained by Product SKU or Id. For example, use this method to obtain the product from SKU: Magento\Catalog\Api\ProductRepositoryInterface::get($sku)
  • Customer Id. On frontend customer ID can be obtained for the currently logged customer using this method: Magento\Customer\Model\Session::getId()

To save the product, first load the customer’s wishlist, then add the product via the Wishlist model.

Coding sample:

<?php

class AddProductToWishlist
{
   protected $_wishlistFactory;
   protected $_wishlistResource;

   public function __construct(
       Magento\Wishlist\Model\WishlistFactory $wishlistFactory,
       Magento\Wishlist\Model\ResourceModel\Wishlist $wishlistResource
   ) {
       $this->_wishlistFactory  = $wishlistFactory;
       $this->_wishlistResource = $wishlistResource;
   }

   /**
    * @param $product
    * @param $customerId
    *
    * @throws \Magento\Framework\Exception\AlreadyExistsException
    * @throws \Magento\Framework\Exception\LocalizedException
    */
   public function saveProductToWishlist($product, $customerId)
   {
       //load wishlist by customer id
       $wishlist = $this->_wishlistFactory->create()->loadByCustomerId($customerId, true);

       //add product for wishlist
       $wishlist->addNewItem($product);

       //save wishlist
       $this->_wishlistResource->save($wishlist);
   }
}

And here is the result: The product has been added to the user's favorite list successfully in the frontend.
