How to add new product to particular customer's wishlist in Magento2?

Question

Can anyone help me out? I want to add new products to the particular customer's wishlist automatically.

Answer 1

<?php   
  $customerId = 2;
  $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
  $productCollection = $objectManager- >create('Magento\Catalog\Model\ResourceModel\Product\Collection');

 $collection = $productCollection->addAttributeToSelect('*')
  ->setPageSize(3)
  ->addAttributeToSort('updated_at', 'DESC')
  ->load();

 foreach($collection as $product){

$product = $objectManager->create('Magento\Catalog\Model\Product')->load($product->getId());


$wishList = $objectManager->get('\Magento\Wishlist\Model\WishlistFactory');

$wishlistAdd = $wishList->create()->loadByCustomerId($customerId, true);
$wishlistAdd->addNewItem($product);
$wishlistAdd->save();

}

?>

I highly recommend to inject Magento\Catalog\Model\Product and Magento\Wishlist\Model\WishlistFactory in your constructor.

This is for your just quick snippet.

Hope it will help you.

You have use Magento\Wishlist\Model\Wishlist class.

First you need to load a customer wishlist by calling function loadByCustomerId()

Then add a new item to wish list using method addNewItem

Code:

<?php
namespace {NameSpaceofClass};
class {Classname}{

    protected $_wishlistFactory;

    public function __construct(
         \Magento\Wishlist\Model\WishlistFactory $wishlistFactory
    )
    {
       $this->_wishlistFactory = $wishlistFactory
    }

    public function addAnewProduct()
    {
        $wishlist = $this->_wishlistFactory->create();

        $wishlist->loadByCustomerId(15); //15 is Customer Id

        if($wishlist){
                $wishlist->addNewItem(25); // 25 Product id
        }
    }
}

Note that:

addNewItem has 3 parameters

1. $product can Product id OR product object which should be instance \Magento\Catalog\Model\Product.

2. $buyRequest , it should be instance

   \Magento\Framework\DataObject or array or string or null

. 3. $forciblySetQty boolean true/false forcefully set qty.

This is the code I have used in my controller

  <?php
     namespace Wishorder\Asorder\Controller\Index;

      use \Magento\Framework\App\Action\Context;
      use   \Magento\Framework\View\Result\PageFactory ;
      use   \Magento\Wishlist\Model\WishlistFactory ;

      class Index extends \Magento\Framework\App\Action\Action
      {

        protected $resultPageFactory;
        protected $wishlistFactory;

        public function __construct(Context $context
        \Magento\Framework\View\Result\PageFactory $resultPageFactory, 
        \Magento\Wishlist\Model\WishlistFactory $wishlistFactory
        )
       {
          $this->resultPageFactory = $resultPageFactory;
          $this->wishlistFactory = $wishlistFactory;
          parent::__construct($context);
       }
public function execute()
{
    $wishlist = $this->wishlistFactory->create();

    $wishlist->loadByCustomerId(1); //15 is Customer Id
    $resultPage = $this->resultPageFactory->create();
    if($wishlist){
            $wishlist->addNewItem(25); // 25 Product id
            $wishlist->save(); // 25 Product id     
    }
    return $this->resultPageFactory->create();
}
}
?>
