destoon实现调用当前栏目分类及子分类和三级分类的方法：
调用当前栏目分类及子分类和三级分类是程序设计里常用的方法，本文就来详细讲述destoon实现调用当前栏目分类及子分类和三级分类的方法。具体操作如下：
在destoon中提供了如下的调用语句：
- 一级分类名：{$m[catname]}
- 二级分类名：{$c[catname]}
- 三级分类名：{$b[catname]}
具体调用示例如下：
一、直接调用分类名称和链接：
{loop $maincat $i $m}<dl>
{php $child = get_maincat($maincat, $CATEGORY, 1);}
<dt><a href="{$MOD[linkurl]}{$m[linkurl]}" rel="external nofollow" rel="external nofollow" >{$m[catname]}</a></dt>
{php $childs = get_maincat($m[catid], $CATEGORY, 1);}
{loop $childs $i $c}<dd><a href="{$MOD[linkurl]}{$c[linkurl]}" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{$c[catname]}</a></dd>{/loop}
</dl>{/loop}
二、调用分类名和其下最新文章：
{loop $maincat $i $m}
{php $child = get_maincat($maincat, $CATEGORY, 1);}
<div class="hq01">
<div class="hq-tt">
<p><h4>{$m[catname]}</h4>
{php $a = get_maincat($m[catid], $CATEGORY, 1);}
{loop $a $g}
{php $f = get_maincat($g[catid], $CATEGORY, 1);}
{loop $f $i $b}
<span><a href="{$MOD[linkurl]}{$c[linkurl]}" rel="external nofollow" rel="external nofollow" rel="external nofollow" >{$b[catname]}</a></span>
{/loop}
{/loop}
<span class="hqmore"><a href="{$MOD[linkurl]}{$m[linkurl]}" rel="external nofollow" rel="external nofollow" >[更多]</a></span> </p>
</div>
<div class="clear"></div>
{php $childs = get_maincat($m[catid], $CATEGORY, 1);}
{loop $childs $i $c}
<div class="hq-cc">
<!--{php $tags=tag("moduleid=$moduleid&condition=status=3&areaid=$cityid&length=40&catid=".$c[catid]."&order=".$MOD[order]."&pagesize=5&datetype=2&target=_blank&template=null")}-->
<ul>
<li class="li-t"><span><a href="{$MOD[linkurl]}{$c[linkurl]}" rel="external nofollow" rel="external nofollow" rel="external nofollow" >---更多</a></span>{$c[catname]}</li>
{loop $tags $t}
<li><!-- <span class="f_r">{date('Y-m-d', $t[addtime])} </span> -->
<a href="{$t[linkurl]}" rel="external nofollow" {if $target} target="{$target}"{/if}>{$t[title]}</a>
</li>
{/loop}
</ul>
</div>
{/loop}
<div class="clear"></div>
</div>
<div class="clear"></div>
{/loop}
