一級、二級、三級、四級標簽嵌套法
<ul>
{dede:channelartlist row=7 typeid=top}
<!-- 頂級 -->
<li class="top">
<a href="{dede:field.typeurl/}" >{dede:field name='typename'/}</a>
<ul class="sub">
{dede:channel type=son noself=yes}
<!-- 二級 -->
<li>
<a href="[field:typeurl/]"  title="[field:typename/]">[field:typename/]</a>
<ul>
<!-- 三級 -->
[field:id runphp=yes]
global $dsql;
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=@me And ishidden<>1 order by sortrank asc limit 0,10";
$dsql->SetQuery($sql);
$dsql->Execute('t');
$result = '';
while($row = $dsql->GetArray('t'))
{
$typename = $row['typename'];
$typeurl = GetOneTypeUrlA($row);
$result .= "<li><a href='{$typeurl}'>{$typename}</a></li>";
}
@me = $result;
[/field:id]
</ul>
</li>
{/dede:channel}
</ul>
</li>    
{/dede:channelartlist}
</ul>
上面的是輸出到三級欄目，如果需要四級欄目可以這樣修改三級四級
<!-- 三級/四級 -->
[field:id runphp=yes]
global $dsql;
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=@me And ishidden<>1 order by sortrank asc limit 0,10";
$dsql->SetQuery($sql);
$dsql->Execute('t');
$result = '';
while($row = $dsql->GetArray('t'))
{
    $row['typeurl'] = GetOneTypeUrlA($row);
$result .= "<a href='{$row[typeurl]}'>{$row[typename]}</a>";
//四級
$nsql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=$row[id] And ishidden<>1 order by sortrank asc limit 0,10";
$dsql->SetQuery($nsql);
$dsql->Execute('n');
while($nrow = $dsql->GetArray('n'))
{
$nrow['typeurl'] = GetOneTypeUrlA($nrow);
$result .= "<a href='{$nrow[typeurl]}'>{$nrow[typename]}</a>";
}
}
@me = $result;
[/field:id]
無限級欄目無限分類自定義函數(shù)遞歸法
在 include/extend.func.php 最下面添加
/**
* 取出所有分類
* @param     int   $channel  頻道ID
* @return    string
* 調(diào)用{dede:global.getalltype function='getalltype()'/}
*/
 
function getalltype($channel=0,$line=10)
{
$line = empty($line) ? 10 : $line;
global $dsql,$result;
 
$dsql->SetQuery("SELECT id,typename,typenamedir,typelitpic,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
            FROM `dede_arctype` WHERE reid='$channel' And ishidden<>1 order by sortrank asc limit 0, $line ");
$dsql->Execute($channel);
if($dsql->GetTotalRow($channel)>0)
{
$result .= "<ul>\r\n"; 
while($row = $dsql->GetArray($channel))
{
$id = $row['id'];
$typename = $row['typename'];
$typelink = GetOneTypeUrlA($row);
 
$result .= " <li>\r\n";

前臺模板調(diào)用標簽
{dede:global.getalltype function='getalltype()'/}
