<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>先给大家看一段代码： <br>
</p>
<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
<span><u>复制代码</u></span>
</div>
代码如下:</div>
<div class="msgborder" id="phpcode9" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>

{dede:channelartlist typeid = 3} <br>
<li class="sub_ul1_li"><a href="{dede:field name='typeurl'/}" class="publica">{dede:field name='typename'/}</a> <br>
<ul class="sub_ul2 hide"> <br>
{dede:channel type='son' noself='yes'} <br>
<li><a href="" class="publica">·</a></li> <br>
{/dede:channel} <br>
</ul> <br>
</li> <br>
{/dede:channelartlist} </div>
<br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>这段代码的意思是查询栏目id为3的子栏目然后在查询子栏目的子栏目。</span><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><br style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'><span style='font-family: tahoma, arial, "Microsoft YaHei"; font-size: 14px;'>但是这样会出现一个问题，就是如果该栏目没有子栏目的话，就会取他的同级栏目，那么如何解决{dede:channel type='son'}无子栏目时取同级栏目问题呢？</span>

<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
其实很简单：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
打开：include\taglib\channel.lib.php文件。<br>
找到<br>
if($type=='son' && $reid!=0 && $totalRow==0)<br>
改成<br>
if($type=='son' && $reid!=0 && $totalRow==0 && $noself=='')</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
这样就对了。</p>
