Magento – Event checkout_cart_add_product_complete – Get Quote Item (follow up question)

Don't do this.

Your problem is, that the cart is not yet saved, have a look here:

https://github.com/LokeyCoding/magento-mirror/blob/magento-1.7/app/code/core/Mage/Checkout/controllers/CartController.php#L201-L206

public function addAction()
{
// ...
        $cart->addProduct($product, $params); // <-- you are inside this method
        if (!empty($related)) {
            $cart->addProductsByIds(explode(',', $related));
        }

        $cart->save(); // here is the saving, and therefore after this line,
                       //  quote and items have an id
// ...
        Mage::dispatchEvent('checkout_cart_add_product_complete',
            array('product' => $product, 'request' => $this->getRequest(), 'response' => $this->getResponse())
        );

What you want is to listen on checkout_cart_add_product_complete

If you want to know which items where added this round, just flag them in checkout_cart_product_add_after like $quoteItem->setIsNew() then you can check in checkout_cart_add_product_complete for $quoteItem->getIsNew()

I tested some code here, and I am finding that checkout_cart_product_add_after does include the quote item, after it has been added:

$item = $observer->getQuoteItem();
$quote = $item->getQuote();

echo $item->getId();
