Dede实现同时一级、二级、三级栏目循环调用

本文讲述的是Dede实现同时一级、二级、三级栏目循环调用，需要的朋友可以参考下其中的内容详情。

一、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

functionlib_channel(&$ctag,&$refObj)

{

global$_sys_globals,$envs,$dsql;

$attlist="typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";

extract($ctag->CAttribute->Items,EXTR_SKIP);

$innertext=$ctag->GetInnerText();

$cacheid=trim($cacheid);

if($cacheid!=''){

$likeType=GetCacheBlock($cacheid);

if($likeType!='')return$likeType;

}

$reid=0;

$topid=0;

if(empty($typeid)&&$envs['typeid']!=0)

{

$typeid=$envs['typeid'];

$reid=$envs['reid'];

}else{

$reid=0;

}

if($type==''||$type=='sun')$type="son";

if($innertext=='')$innertext=GetSysTemplets("channel_list.htm");

if($reid==0&&$typeid>0)

{

$dbrow=$dsql->GetOne("SelectreidFromdede_arctypewhereid='$typeid'");

if(is_array($dbrow))$reid=$dbrow['reid'];

}

$likeType='';

二、在模板调用
实例：

{dede:channeltype='son'typeid='22'}

[field:typename/]

ul>

[field:sonchannel0]

li>ahref="http://www.dede58.com/[field:typelink/]">[field:typename/]a>li>

[field:sonchannel1]

li>ahref="http://www.dede58.com/[field:typelink/]">---[field:typename/]a>li>

[field:sonchannel2]

li>ahref="http://www.dede58.com/[field:typelink/]">===[field:typename/]a>li>

[field:sonchannel3]

li>ahref="http://www.dede58.com/[field:typelink/]">===[field:typename/]a>li>

[/field:sonchannel3]

[/field:sonchannel2]

[/field:sonchannel1]
