观看添加到购物车事件-报价项目ID为空

我正在尝试捕获将商品添加到购物车后触发的事件。我目前正在观看以下事件：checkout_cart_product_add_after

根据magento消息来源，在对Quote进行所有操作后，将触发此事件。但是当我访问购物车ID和报价ID时，这些值为空：

$quoteItem = $observer->getQuoteItem();
$quote_item_id = $quoteItem->getItemId();
$cart = Mage::getSingleton('checkout/session');
$quote_id= $cart->getQuoteId();

如果购物车中没有商品，则上面的两个ID均返回空白，如果购物车中已有商品，则该商品ID具有值，但quote_item_id没有。

注意，此问题以前曾被问过，但问题从未得到解决，因此讨论最终偏离了这个问题。我需要quote_item_id。

不要这样

您的问题是，购物车尚未保存，请在此处查看：

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())
        );

你想听的是 checkout_cart_add_product_complete

如果你想知道哪些在加入这一轮的项目，只需将它们标记checkout_cart_product_add_after一样$quoteItem->setIsNew()，你可以在随后检查checkout_cart_add_product_complete的$quoteItem->getIsNew()

您可以使用此checkout_cart_product_add_after事件：

$observer->getEvent()->getQuoteItem()->getProduct()->getData()

返回的数据类似于以下内容：

这已经在Magento 1.9.1.0上进行了测试，但是据我所知，这应该在1.7上有效

您可以使用以下事件

sales_quote_item_set_product

并像这样在观察者中获取商品ID。

$quote_item = $observer->getEvent()->getQuoteItem();
$item_id = $quote_item->getItemId();

我通过在$ cart和quoteItem上调用save解决了此问题。由于我不确定这是最好的方法，因此没有选择正确的方法。

Fabian Blechschmidt解决方案要好得多，请使用该解决方案。
