修改 Magento 的电子邮件模板以包含长描述
Magento 版本
1.6.2.0
正在编辑的文件
app/design/frontend/default/<template name>/template/email/order/items/order/default.phtml
此文件中带有行号的感兴趣代码：
31 <strong style="font-size:11px;"><?php echo $this->htmlEscape($_item->getName()) ?></strong>
46 <?php echo $this->escapeHtml($_item->getDescription()) ?>
问题
$_item -> getName()有效，但$_item -> getDescription()返回 null
调试
$_item的 Zend 转储（显示定义的“名称”；“描述”为空）：

问题
为什么这里的描述为空？
我发现在下订单后更改产品名称不会更改订单中的名称，因此订单对象似乎在订购的产品上有自己的数据，该数据与实时目录分开（我想有道理：您希望该信息是静态且不可更改的）。
由于浪费了数据库中的空间，它不会在每次订购商品时尝试存储商品的长和/或短描述也是有道理的。但是为什么要包含描述字段只是为了将其留空？
我获取该信息以加载目录/产品模型、找到我想要的产品和属性的唯一方法是（就像这里）？
