织梦dede调用四级栏目

织梦调用四级子栏目,首先需要修改文件:\include\taglib\channel.lib.php,请将以下代码全部复制替换上述文件:

2、在模板中调用实例:

01	{dede:channel type='son' typeid='3'}
02	[field:typename/]
03	<ul>
04	[field:sonchannel0]
05	<li><a href="[field:typelink/]">[field:typename/]</a></li>
06	[field:sonchannel1]
07	<li><a href="[field:typelink/]">---[field:typename/]</a></li>
08	[field:sonchannel2]
09	<li><a href="[field:typelink/]">===[field:typename/]</a></li>
10	[field:sonchannel3]
11	<li><a href="[field:typelink/]">===[field:typename/]</a></li>
12	[/field:sonchannel3]
13	[/field:sonchannel2]
14	[/field:sonchannel1]
15	[/field:sonchannel0]
16	</ul>
17	{/dede:channel}
