织梦DedeCMS调用一级二级三级和无限级栏目输出

织梦DedeCMS调用多级子栏目，首先在后台已经建好栏目按照下面的操作步骤将循环调用二级栏目下三级、四级栏目，有类似需求的朋友可以参考下。

一级、二级、三级、四级标签嵌套法

<ul>
    {dede:channelartlist row=7 typeid=top}
    <!-- 顶级 -->
    <li class="top">
        <a href="{dede:field.typeurl/}" >{dede:field name='typename'/}</a>
        <ul class="sub">
            {dede:channel type=son noself=yes}
            <!-- 二级 -->
            <li>
                <a href="[field:typeurl/]"  title="[field:typename/]">[field:typename/]</a>
                <ul>
                    <!-- 三级 -->
                    [field:id runphp=yes]
                    global $dsql;
                    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `#@__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>

上面的是输出到三级栏目，如果需要四级栏目可以这样修改三级四级

<!-- 三级/四级 -->
[field:id runphp=yes]
global $dsql;
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `#@__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
    $nsql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `#@__arctype` WHERE reid=$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]

无限级栏目无限分类自定义函数递归法

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;
    
    $dsql->SetQuery("SELECT id,typename,typenamedir,typelitpic,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
            FROM `#@__arctype` WHERE reid='$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()'/}
