foreach - Smarty 嵌套 for-each 与数组

Question

我在智能 for-each 循环方面遇到了一些麻烦 - 这是我的代码:

{* this example will print out all the values of the $custid array *}
{foreach from=$order_info item=amount}
amount: {$amount}<br>
{/foreach}

所以基本上我只是想循环并打印 $order_info 中的“金额” - 问题是，它只是打印整个数组，而不仅仅是“金额”。

这是我从调试控制台获得的数组中减少的项目数量:

    shipped_amount => "0"
    shipment_amount => "1"

所以我真正想做的是从$order_info内的items获取amount - 我尝试了$order_info.items但是这导致网站崩溃。

非常感谢任何想法。

这解决了它:

{foreach from=$order_info.items item=foo} 
     {$foo.product_id} 
{/foreach}
