首先请大家打开include/taglib/channel.lib.php文件，然后找到
1.在$line = empty($row) ? 100 : $row;在它的下面加上下面代码
//limit条件
$limit = trim(eregi_replace('limit','',$limit));
if($limit!=''){
$limit = " $limit ";
}else{
$limit = " limit 0,$line ";
}

2.然后把下面的

if($type=='top')
{
$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
From `80php_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line ";
}
else if($type=='son')
{
if($typeid==0) return '';
$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
From `80php_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit $limit ";
}
else if($type=='self')
{
if($reid==0) return '';
$sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
FROM `80php_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
}

将limit 0, $line 改成$limit

3.使用方法：

{dede:channel type='son' typeid=68 limit='0,6'}
<a href="[field:typeurl/]">[field:typename/]</a>
{/dede:channel}
