dede的栏目只能循环一次。所以需要修改,在织梦5.7中试验了一下可以用。 修改文件:\include\taglib目录下的channel.lib.php,请将以下代码全部复制替换上述文件。
以下为引用的内容:
- <?php
- function lib_channel(&$ctag,&$refObj)
- {
- global $_sys_globals,$envs,$dsql;
- $attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";
- FillAttsDefault($ctag->CAttribute->Items,$attlist);
- extract($ctag->CAttribute->Items, EXTR_SKIP);

- $cacheid = trim($cacheid);

- $likeType = GetCacheBlock($cacheid);
- if($likeType != '') return $likeType;
- }
- $reid = 0;

模板调用 [field:sonchannel0] [/field:sonchannel0] 这个是用来取子栏目用得(使用[sonchannel+数字] 作为标签名是为了防止嵌套的时候无法正确解析标签)
这个的作用就是当你的栏目有很多子栏目 无限分级的时候方便你取子栏目的
例子:
{dede:channel type='son' typeid='22'}
[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}
