Question

我在使用Smart for-each循环时遇到了一些麻烦 - 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}

所以基本上我只是试图循环并打印来自$ order_info的“金额” - 问题是，它只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：

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

所以我真正要做的就是从amount items中获取$order_info - 我尝试了$ order_info.items，但这导致网站崩溃。

非常感谢任何想法。

Answer 1

这解决了它：

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

Answer 2

不会像

那样

{foreach from=$order_info.items item=items}
    {foreach from=$items item=item}
        amount: {$item.amount}<br>
    {/foreach}
{/foreach}

假设我将您的结构理解为$ order_info - ＆gt; items array - ＆gt; （项目项目项目），以及具有.amount属性的每个项目。

Smarty用数组嵌套for-each
