使用smarty模板引擎从对象获取数组值

Question

我无法弄清楚如何获取属性。这将被发送到我的智能模板。

      string(1) "5"
      ["discount"]=>
      string(1) "0"
    }
  }

这就是我在smarty模板中所拥有的，并且抛出的错误表示尝试非对象的属性。

    <tr>
         <td>{$result->order_id}</td><!--Works -->
             <td>{$result->order_date}</td><!--Works -->
             <td>{$result->customer->company_name}</td><!--Works -->

        <!--Doesn't Work, says trying to get property of non object-->
        {foreach $result as $r}
              <td>{$r->order_detail->product->product_id}</td>
        {/foreach}
     </tr>

任何帮助都将不胜感激，谢谢。
