调用三级四级无限级栏目效果图



适用于前端简单样式用户，在 include/extend.func.php最后面加上：

/**
  * 取出所有分类
  * @param   int   $channel  频道ID
  * @return  string  www.dedeyuan.com
  * 调用{dede:global.getalltype function='getalltype()'/}
  */
  
  function getalltype($channel=0,$line=10)
  {
       $line = empty($line) ? 10 : $line;
       global $dsql,$result;
       
       $dsql->SetQuery("SELECT id,typename,typenamedir,typelitpic,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
        FROM `dede_arctype` WHERE reid='$channel' And ishidden<>1 order by sortrank asc limit 0, $line ");
       $dsql->Execute($channel);
       if($dsql->GetTotalRow($channel)>0)
       {
             $result .= "<ul>
";
             while($row = $dsql->GetArray($channel))
             {
                $id = $row['id'];
                $typename = $row['typename'];
                $typelink = GetOneTypeUrlA($row);
  
                $result .= "     <li>
";
                $result .= "        <a href='{$typelink}' target='_blank'>{$typename}</a>
";
                getalltype($id,$line);
                $result .= "     </li>
";
             }
      $result .= "</ul>
";
       }
       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}
       <!-- 顶级 -->
       <li>
             <a href="{dede:field.typeurl/}" >{dede:field name='typename'/}</a>
             <ul>
             {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 `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);
  $result .= <<< TPL
  <li><a href="{$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

<!-- 三级/四级 -->
  [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>";
       //四级
       $nsql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath 
       FROM `dede_arctype` WHERE reid=$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]
