How to do this? I am using checkout_cart_product_add_after event.


After I did it like this

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
  <event name="sales_quote_item_set_product">
      <observer name="changesku" instance="Vdndor\ProductChanger\Observer\ChangeSKU" />

and Observer as


namespace Vendor\ProductChanger\Observer;

use Magento\Framework\Event\Observer;
use Magento\Framework\Event\ObserverInterface;

class ChangeSKU implements ObserverInterface
     * Below is the method that will fire whenever the event runs!
     * @param Observer $observer
    public function execute(Observer $observer)
        $event = $observer->getEvent();
        $quoteItem = $event->getQuoteItem();

        $quoteItem->setName("SAMPLE NAME");


But still it is changing the SKU and NAME in quote_item table perfectly when I add it to cart. But whenever I go the cart page or I place the order the old NAME and SKU are saving back. any help?

Use the following one for checkout_cart_product_add_after event

class Mynamespace_Model_Observer
    public function salesQuoteItemSetProduct(Varien_Event_Observer $observer)
        /* @var $item Mage_Sales_Model_Quote_Item */
        $item = $observer->getQuoteItem();

        //only change the item you want by product id
        if($item->getProductId() == "abc"){
            $item->setName('Custom Product Name');

        return $this;
  • Thanks @Mitul Vadalia... I tried ur approach for the same event you suggested too. but it is not changing the name permanently. That is the problem Commented Oct 13, 2022 at 10:33

You can try to add an around plugin on the save method of the following repositories:

  • \Magento\Quote\Api\CartItemRepositoryInterface
  • \Magento\Quote\Api\GuestCartItemRepositoryInterface

Something like:

public function aroundSave(
        \Magento\Quote\Api\CartItemRepositoryInterface $cartItemRepository, 
        callable $proceed, 
        \Magento\Quote\Api\Data\CartItemInterface $cartItem
    ) {
        $cartItem->setSku('YOUR SKU');
        return $proceed;

Another solution is to add a preference for the same repositories, inherit original class and add a new implementation for the save method.
