我$cs_map_data在 PHP 文件中命名了以下多维数组，并将其分配给 smarty 模板：

现在我想访问 key [cs_map_id] 和[subject_name]smarty 模板中每个元素的值。我尝试使用 foreach 但无法从 key[cs_map_id]和[subject_name]. 任何人都可以帮助我了解如何在 smarty 中访问 key[cs_map_id]和[subject_name]foreach 循环中的值。我在 smarty 模板中编写的代码如下：
<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>
任何人都可以帮助我如何在 smarty 模板中使用 forech 中的两个键值吗？提前致谢。
