How to add programmatically product to wishlist in Magento 2?

Question

I want to add the product to the wishlist in magento2.

What is the way to programmatically add the product into wishlist in Magento2?

Answer 1

To do so, you will first have to inject the following in your constructor:

• Magento\Wishlist\Model\WishlistFactory
• Magento\Catalog\Api\ProductRepositoryInterface

So update your class constructor like this:

protected $_wishlistRepository;

protected $_productRepository;

public function __construct(
    ...
    \Magento\Wishlist\Model\WishlistFactory $wishlistRepository,
    \Magento\Catalog\Api\ProductRepositoryInterface $productRepository
) {
    $this->_wishlistRepository= $wishlistRepository;
    $this->_productRepository = $productRepository;
    ...
}

Then in you can do the following, please note your need both the customer id and the product id to add a product to the wishlist:

try {
    $product = $this->_productRepository->getById($productId);
} catch (NoSuchEntityException $e) {
    $product = null;
}

$wishlist = $this->_wishlistRepository->create()->loadByCustomerId($customerId, true);

$wishlist->addNewItem($product);
$wishlist->save();
