Question

我最近将我的Magento商店从1.4.2升级到1.7.0.2。现在，当我尝试将产品添加到购物车时，它会显示以下错误：

无法将商品添加到购物车。

这是堆栈跟踪：

如果有帮助的话，我正在尝试将简单的产品添加到购物车中。

知道发生了什么事吗？

Answer 1

检查您的代码中是否有任何观察者，或者您添加的新扩展程序在您向卡中添加项目时会触发，请找到我为解决问题而修复的以下代码

原件：

$item = $observer->getEvent()->getQuoteItem();
$product = $item->getProduct();
$item->setMerchant($product->getMethant());
$item->save();

解决方案：

$quoteItem = $observer->getQuoteItem();
$product = $observer->getProduct();
$quoteItem->setCustomAttribute($product->getCustomAttribute());

Answer 2

好的，我试图理解是什么引起了这个错误，但无济于事。

所以我通过安装Magento 1.7的全新安装解决了这个问题，并从那里升级了我的magento商店。

无法将商品添加到购物车。 Magento 1.7
