Unable to get newly inserted Product's Id using After Plugin for Catalog Product save controller method

Question

I have created interceptor for catalog product controller's save action

<type name="Magento\Catalog\Controller\Adminhtml\Product\Save">
    <plugin name="ricky_catalog_save_product"
            type="Ricky\Catalog\Plugin\Product\Save" sortOrder="10"
    />
</type>

My plugin class is below

namespace Ricky\Catalog\Plugin\Product; 

class Save {
     public function afterExecute(
          \Magento\Catalog\Controller\Adminhtml\Product\Save $subject,
           $result)
    {
         $productId = $subject->productId; // This is not working
         /**
         echo $result->getProduct->getId(); die("prodid");
         echo $subject->getProduct->getId(); die("prodid");
         Both throw exception: Undefined property $getProduct
        **/

         /** $productId is provided in excute method in Save class 
            in Magento\Catalog\Controller\Adminhtml\Product\Save **/
    }
}

For some reasons I have to use Plugin (Interceptor Design Pattern), I know I can get newly created prouduct id by using observer for catalog_product_save_after event. But please provide solution for plugins.

I am asking this after visiting This Solution

Thanks for help :)

Answer 1

The variable $product is not accessible from outside the save method. The only exceptioon is the event controller_action_catalog_product_save_entity_after. But the product builder puts the product into registry, so you may access the product from there. This code should work in my opinion, but I didn't test it:

    public function __construct(
        \Magento\Framework\Registry $registry
    )
    {
        $this->registry = $registry;
    }

    public function afterExecute(
      \Magento\Catalog\Controller\Adminhtml\Product\Save $subject,
       $result)
    {
        //get the product from registry
        $product = $this->registry->registry('current_product');
        $productId = $product->getId();

        return $result;
    }
