将产品添加到购物车后获取报价项目ID

Question

I need to get quote item id of the product when it is added to cart because I need to update a field of Db after this event,I have taken reference from How to get Quote Item Id after adding a product to cart?, but this is not working,I have used event: sales_quote_product_add_after and my oberver function is:

$quoteItem = $observer->getEvent()->getQuoteItem();
$id = $quoteItem->getId();

also I have tried with

$id = $quoteItem->getItemId();

It is throwing following Fatal error:

Fatal error</b>:  Call to a member function getId() on a non-object in <b>C:\xampp\htdocs\project\app\code\local\Custom\Module\Model\Observer.php</b> on line <b>1053</b><br />

Please let me know what I am doing wrong,I have taken reference from many other links too but none of them is working.

Answer 1

As per my understanding, You will not get QuoteItems keys for this event. This event provide items array which contain all the items which are getting added for a product. So you don't have to change your code a lot.

$item = $observer->getEvent()->getItems()[0];
$item_id =  $item->getId();

It should give you desired result.
