How to Extract Simple Product Information while adding product to wishlist in Magento 2?

Extract simple product sku when adding product to wishlist in Magento 2

Our team was trying to send simple / child product to Facebook as part of the event tracking but it took us a while to figure out how to extract the information like simple product name, sku and price. Because by default it gives you only product ID of the configurable / parent product along with variant information like size and colour IDs but no information related to the simple / child product.

There are following wishlist events available which can be used to retrieve wishlist item(s) which can further be used to retrieve product ID of the simple / child product -:

1. wishlist_add_product $this->_eventManager->dispatch(‘wishlist_add_product’,[‘wishlist’ => $wishlist, ‘product’ => $product, ‘item’ => $result]);
2. wishlist_product_add_after $this->_eventManager->dispatch(‘wishlist_product_add_after’, [‘items’ => $items]);
3. wishlist_add_item$this->_eventManager->dispatch(‘wishlist_add_item’, [‘item’ => $item]);

wishlist_add_product and wishlist_add_item will give you item level information which will help you extract simple product information while wishlist_product_add_after will give you information about all the items which have been added to the wishlist

In this post, we will use wishlist_add_product to retrieve simple product SKU which was added to the wishlist by the customer

Step 1: Create events.xml under ScommerceCustometcfrontend folder with the following code -:

<br>
&lt;?xml version="1.0" encoding="UTF-8"?&gt;<br>
&lt;config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd"&gt;<br>
&lt;event name="wishlist_add_product"&gt;<br>
&lt;observer name="scommerce_custom_wishlist_add_product" instance="ScommerceCustomModelObserverWishlistAddProduct" /&gt;<br>
&lt;/event&gt;<br>
&lt;/config&gt;<br>

Step 2: Create WishlistAddProduct.php under ScommerceCustomModelObserver folder with the following code -:

<br>
&lt;?php<br>
/**<br>
* Copyright © 2015 Scommerce Mage. All rights reserved.<br>
* See COPYING.txt for license details.<br>
*/<br>
namespace ScommerceCustomModelObserver;</p>
<p>use MagentoFrameworkEventObserver as EventObserver;<br>
use MagentoFrameworkEventObserverInterface;</p>
<p>class WishlistAddProduct implements ObserverInterface<br>
{</p>
<p>/**<br>
* @var MagentoFrameworkObjectManagerInterface<br>
*/<br>
protected $_objectManager;</p>
<p>/**<br>
* @param MagentoFrameworkObjectManagerInterface $objectmanager<br>
*/<br>
public function __construct(MagentoFrameworkObjectManagerInterface $objectmanager)<br>
{<br>
$this-&gt;_objectManager = $objectmanager;<br>
}</p>
<p>public function execute(EventObserver $observer)<br>
{<br>
$productId = $observer-&gt;getItem()-&gt;getOptionByCode('simple_product')-&gt;getValue();<br>
$product = $this-&gt;_objectManager-&gt;create('MagentoCatalogModelProduct')<br>
-&gt;load($productId);</p>
<p>if (!$product-&gt;getId()) {<br>
return;<br>
}<br>
return $product-&gt;getSku();<br>
}<br>
}

Below is the piece of code which will help you retrieve product id of the simple product which was choosen by the customer while adding product to wishlist.

$observer->getItem()->getOptionByCode(‘simple_product’)->getValue();
