如何从smarty中的多维数组访问密钥？

我有一个名为$cs_map_data在PHP文件以下多维数组，我已经将其分配到Smarty模板：如何从smarty中的多维数组访问密钥？

Array

         ) 

       ) 

     )

现在我要访问键[cs_map_id]的价值和[subject_name]每个元素的在聪明的模板。我尝试使用foreach，但无法获得密钥[cs_map_id]和[subject_name]的值。任何人都可以帮助我如何访问smarty中foreach循环中的密钥[cs_map_id]和[subject_name]的值。本人在智者的模板写代码如下：

<table>       
       <tr> 
       {assign var='i' value=0} 
       {if $cs_map_data} 
       {foreach from=$cs_map_data item="map_data"} 
       {if $i%4 == 0}</tr><tr>{/if} 
       <td align="left" valign="top" width="150"> 

        <input type="checkbox" name="cs_map_id[]" id="{$map_data.cs_map_id}" value="{$map_data.cs_map_id}" onChange="get_test_by_category('{$map_data.cs_map_id}'); return false;" /> 
       {$map_data.subject_name} 
       </td> 
       {assign var='i' value=$i+1} 
       {/foreach} 
       {else} 
         <td> 
          <i>No Subject is assigned to the class.</i> 
        </td> 
       {/if} 
       </tr> 
       </table>

任何一个可以帮助我如何在forech在智者模板中使用两个关键的价值观？在此先感谢。

你在使用Smarty 2还是3？ – eidsonator 2013-05-07 14:23:59

@eidsonator Smarty 2 – PHPLover 2013-05-07 14:27:24

啊，这就是我从你的foreach语法中想到的。我对3更加熟悉......并且在2和3之间的这个区域有一些大的变化。但是我认为你想用一个{SECTION}而不是一个foreach，并且你必须将它们嵌套到遍历“内部”数组。 – eidsonator 2013-05-07 14:31:32

这将在Smarty 2和3中工作。{foreach}在版本之间有很大变化，但{section}的工作原理相同。

{section name=map loop=$cs_map_data} 
    <tr> 
     <td>{$cs_map_data[map].class_name}</td> //this is the format to access your data from the array 
    {section name=subject loop=$cs_map_data[map].class_subjects} 
      <td> 
       {$cs_map_data[map].class_subjects[subject].subject_name} //this is how to access the entries of your 'inner' array 
      </td> 
    {/section} //end your nested section 
    </tr> 
{/section} //end your outer section

应通过你的阵列的工作循环......

祝你好运！

非常感谢。你的代码为我做了必要的魔术。再次感谢你挽救我的生命。 – PHPLover 2013-05-07 15:13:54

当我第一次开始学习聪明的时候，花了两天时间来解决这个问题！这很复杂，但是当你将头部缠绕在头上时，它非常简单。祝你的项目好运！ – eidsonator 2013-05-07 15:17:36
