织梦dede调用四级栏目的实现方法_dedecms_CMS教程_迪尔课堂

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:XjH迪尔课堂自学网-|第二课堂|--(官网)

2、在模板中调用实例:XjH迪尔课堂自学网-|第二课堂|--(官网)

{dede:channel type='son' typeid='3'}[field:typename/]<ul>[field:sonchannel0]<li><a href="[field:typelink/]">[field:typename/]</a></li>[field:sonchannel1]<li><a href="[field:typelink/]">---[field:typename/]</a></li>[field:sonchannel2]<li><a href="[field:typelink/]">===[field:typename/]</a></li>[field:sonchannel3]<li><a href="[field:typelink/]">===[field:typename/]</a></li>[/field:sonchannel3][/field:sonchannel2][/field:sonchannel1][/field:sonchannel0]</ul>{/dede:channel}
