dedecms织梦调用三级四级无限级栏目教程

调用三级四级无限级栏目效果图

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  www.80zhan.com织梦模板下载

    * 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 .= "

rn";

                       while($row = $dsql->GetArray($channel))

                       {

                                $id = $row['id'];

                                $typename = $row['typename'];

                                $typelink = GetOneTypeUrlA($row);

 

                                $result .= "      
• rn";
  
                                  $result .= "                {$typename}rn";
  
                                  getalltype($id,$line);
  
                                  $result .= "      
rn";

                       }

            $result .= "

rn";

             }

             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   

             {dede:channelartlist row=7 typeid=top}

            

            
• 
  
                         {dede:field name='typename'/}
  
                        
  
  
                         {dede:channel type=son noself=yes}
  
                        
  
                        
  • 
    
                           [field:typename/]
    
                          
    
    
       
    
        [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
    
       
    • {$typename}
    
    
        TPL;
    
        }
    
        @me = $result;
    
        [/field:id]
    
                          
    
    
                          
  
  
                         {/dede:channel}
  
                        
  
  
              
  

             {/dede:channelartlist}

   

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 `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);

             $result .= "{$row[typename]}";

             //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);

                       $result .= "{$nrow[typename]}";

             }

    }

    @me = $result;

    [/field:id]
