如何從smarty中的多維數組訪問密鑰？

我有一個名爲$cs_map_data在PHP文件以下多維數組，我已經將其分配到Smarty模板：如何從smarty中的多維數組訪問密鑰？

         ) 

       ) 

     ) 

)

現在我要訪問鍵[cs_map_id]的價值和[subject_name]每個元素的在聰明的模板。我嘗試使用foreach，但無法獲得密鑰[cs_map_id]和[subject_name]的值。任何人都可以幫助我如何訪問smarty中foreach循環中的密鑰[cs_map_id]和[subject_name]的值。本人在智者的模板寫代碼如下：

<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>

任何一個可以幫助我如何在forech在智者模板中使用兩個關鍵的價值觀？在此先感謝。

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

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

啊，這就是我從你的foreach語法中想到的。我對3更加熟悉......並且在2和3之間的這個區域有一些大的變化。但是我認爲你想用一個{SECTION}而不是一個foreach，並且你必須將它們嵌套到遍歷「內部」數組。 – eidsonator 2013-05-07 14:31:32

這將在Smarty 2和3中工作。{foreach}在版本之間有很大變化，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

應通過你的陣列的工作循環......

祝你好運！

非常感謝。你的代碼爲我做了必要的魔術。再次感謝你挽救我的生命。 – PHPLover 2013-05-07 15:13:54

當我第一次開始學習聰明的時候，花了兩天時間來解決這個問題！這很複雜，但是當你將頭部纏繞在頭上時，它非常簡單。祝你的項目好運！ – eidsonator 2013-05-07 15:17:36
