Hi all I am using Magento 2 and I want to get the product Id on all pages. Now i amable to get the product id in product details pae (Product single page). but i am not getting those in product listing pages. it says calling undefined object like error message.


namespace Vendor\module\Plugin;

class Product
public function afterGetPrice(\Magento\Catalog\Model\Product $subject, $result)
    $objectManager = \Magento\Framework\App\ObjectManager::getInstance(); // Instance of object manager
    $resource = $objectManager->get('Magento\Framework\App\ResourceConnection');

    $product- = $objectManager->get('Magento\Framework\Registry')->registry('current_product');//get current product
    // here this $product is seems like undefined only in product listing pages.

    return $result + 100;

Please see comment in my code, how can I get the product id here? Please help.


Logic is not right. You are using a plugin, so do not need to use registry current_product.

$subject can provide the product id using $subject->getId()

  • Yes that is perfect! – Sanjun Dev Sep 9 '19 at 9:11
  • One more question, i got the ID, but the same way i am not getting the weight and price of the product like this. $subject->getWeight(); but it is coming in detail page of that product – Sanjun Dev Sep 9 '19 at 17:08
