**分享2种方法获取织梦所有栏目(无限级栏目输出)：**

**第一种自定义函数递归法**

适用于前端简单样式用户，在 include/extend.func.php 最下面添加

/**
    
    * 取出所有分类
    
    * @param     int   $channel  频道ID
    
    * @return    string
    
    * 调用{dede:global.getalltype function='getalltype()'/}
    
    */function getalltype($channel=0,$line=10){
    
    $line = empty($line) ? 10 : $line;
    
    global $dsql,$result;
    
    
    $dsql->SetQuery("SELECT id,typename,typenamedir,typelitpic,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath            FROM `SzsFox_arctype` WHERE reid='$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";
    
    $result .= "<a href='{$typelink}' target='_blank'>{$typename}</a>\r\n";
    
    getalltype($id,$line);
    
    $result .= "</li>\r\n";
    
    }
    
            $result .= "</ul>\r\n";
    
    }
    
    return $result;}

**前台模板调用标签：**

{dede:global.getalltype function='getalltype()'/}

**第二种标签嵌套法：**

适用于只调用出一级、二级、三级、四级的用户，直接在模板里写

<ul>
        {dede:channelartlist row=7 typeid=top}
    
    <li class="top">
    <a href="{dede:field.typeurl/}" >{dede:field name='typename'/}</a>
    <ul class="sub">
    {dede:channel type=son noself=yes}
    
    <li>
    <a href="[field:typeurl/]"  title="[field:typename/]">[field:typename/]</a>
    <ul>[field:id runphp=yes]global $dsql;$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `SzsFox_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);$result .= <<< TPL<li><a href="{$typeurl}">{$typename}</a></li>TPL;}@me = $result;[/field:id]
    </ul>
    </li>
    {/dede:channel}
    </ul>
    </li>{/dede:channelartlist}
    </ul>

上面的是输出到三级栏目，如果需要四级栏目可以这样写

[field:id runphp=yes]global $dsql;$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `SzsFox_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>";
    //四级
    $nsql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `SzsFox_arctype` WHERE reid=$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]
