smarty section foreach遍历多维数组

说明:

section  一般针对键号是连续数字的
array(
0 => 1,
1 => 2
)

如果你的键号是字符串的，那么一定要用foreach来实现
array(
'xxx' => 1,
'yyy' => 2
)

• 多维数组section实例

例如数据集为:

Array
(
    [0] => Array
        (
            [Tid] => 21
            [Updated] => 2007-12-31 10:21:18
            [Created] => 2007-12-31 10:21:18
            [Typename] => 系统相关
            [Fid] => 0
        )

    [1] => Array
        (
            [Tid] => 20

                        )

                )

        )

)

在使用模板时:可以采用以下写法:
{{section name=list loop=$Atcs}}<!-- 一级类别 -->
<div align="left">{{$Atcs[list].Typename}}</div>

{{assign var=SmallType value=$Atcs[list].SmallType}}<!-- 二级类别 -->
{{section name=list1 loop=$SmallType}}
<div align="left">&nbsp;-->{{$SmallType[list1].Typename}}</div>

{{assign var=TopAtc value=$SmallType[list1].TopArticle}}<!-- 二级分类中 的几篇文章 -->
{{section name=list2 loop=$TopAtc}}
<div align="left">&nbsp;&nbsp;&nbsp;-------{{$TopAtc[list2].Title}} -----{{$TopAtc[list2].Created}}</div>
{{/section}}

{{/section}}
<hr />
{{/section}}

显示结果为:

foreach遍历多维数组
数组的样子为：
array(
　　'table1' => array(
　　　　　　　　　　　　'seq' => kkk
　　　　　　　　　　　　'title' => b
　　　　　　　　)
)

{foreach key=key item=item from=$dataList name=foo}    
        {section name=l loop=$item}
            <li><a href="#{$item[l].SEQ}" >·{$item[l].TITLE}</a></li>
        {/section}
{/foreach}
