dedecms中实现列表页面调用其它栏目的信息

 群里有人问如何在dedecms中实现列表页面调用不同栏目的文章信息，以下给出解决方法，针对dedecms4.0。

首先，为dedecma增加一个标签的属性，我修改的标签为【List 标记】增加属性addonid，使用方法为：

addonid= '调用的栏目编号'，不同的栏目请用半角“,”的分隔，这些栏目必须是最终列表栏目，同时不必在这个栏目编号中增加本栏目的编号。

例子：{dede:list pagesize='2' addonid='1,2'} {/dede:list}

继续修改include/inc_arclist_view.php，这个比较麻烦，不会的话，直接拷贝粘贴。

第一步，新增$addonid变量，如下：

class ListView
{
 var $dsql;
 var $dtp;
 var $dtp2;
 var $TypeID;
 var $TypeLink;
 var $PageNo;
 var $TotalPage;
 var $TotalResult;
 var $PageSize;
 var $ChannelUnit;
 var $ListType;
 var $Fields;
 var $PartView;
 var $StartTime;
 var $addonid; //这里为新增的变量

……

第二步：获得模板中的addonid的值，并且统计文章总数，修改function CountRecord()函数：

原本代码为：

  //------------------
  //统计列表里的记录
  //------------------
  function CountRecord()
  {
   global $cfg_list_son;
   //统计数据库记录
   $this->TotalResult = -1;
   if(isset($GLOBALS['TotalResult'])) $this->TotalResult = $GLOBALS['TotalResult'];
   if(isset($GLOBALS['PageNo'])) $this->PageNo = $GLOBALS['PageNo'];
   else $this->PageNo = 1;
   
   if($this->TotalResult==-1)
   {
     $addSql  = " arcrank > -1 ";
     
     if($cfg_list_son=='否') $addSql .= " And (typeid='".$this->TypeID."' or typeid2='".$this->TypeID."') ";
     else $addSql .= " And (".$this->TypeLink->GetSunID($this->TypeID,"#@__archives",$this->Fields['channeltype'])." Or #@__archives.typeid2='".$this->TypeID."') ";
     
     if($this->StartTime>0) $addSql .= " And senddate>'".$this->StartTime."'";
     $cquery = "Select count(*) as dd From #@__archives where $addSql";
    $row = $this->dsql->GetOne($cquery);
    if(is_array($row)) $this->TotalResult = $row['dd'];
    else $this->TotalResult = 0;
   }
   
   //初始化列表模板，并统计页面总数
   $tempfile = $GLOBALS['cfg_basedir'].$GLOBALS['cfg_templets_dir']."/".$this->TypeLink->TypeInfos['templist'];
   $tempfile = str_replace("{tid}",$this->TypeID,$tempfile);
   $tempfile = str_replace("{cid}",$this->ChannelUnit->ChannelInfos['nid'],$tempfile);
   if(!file_exists($tempfile)){
       $tempfile = $GLOBALS['cfg_basedir'].$GLOBALS['cfg_templets_dir']."/".$GLOBALS['cfg_df_style']."/list_default.htm";
    }
   if(!file_exists($tempfile)||!is_file($tempfile)){
    echo "模板文件：'".$tempfile."' 不存在，无法解析文档！";
    exit();
   }
   $this->dtp->LoadTemplate($tempfile);
   $ctag = $this->dtp->GetTag("page");
   if(!is_object($ctag)){ $ctag = $this->dtp->GetTag("list"); }
   if(!is_object($ctag)) $this->PageSize = 20;
   else{
     if($ctag->GetAtt("pagesize")!="") $this->PageSize = $ctag->GetAtt("pagesize");
      else $this->PageSize = 20;
    }
    $this->TotalPage = ceil($this->TotalResult/$this->PageSize);
  }

修改为：

  //------------------
  //统计列表里的记录
  //------------------
  function CountRecord()
  {
   global $cfg_list_son;
  
   //初始化列表模板，并统计页面总数
   $tempfile = $GLOBALS['cfg_basedir'].$GLOBALS['cfg_templets_dir']."/".$this->TypeLink->TypeInfos['templist'];
   $tempfile = str_replace("{tid}",$this->TypeID,$tempfile);
   $tempfile = str_replace("{cid}",$this->ChannelUnit->ChannelInfos['nid'],$tempfile);
   if(!file_exists($tempfile)){
       $tempfile = $GLOBALS['cfg_basedir'].$GLOBALS['cfg_templets_dir']."/".$GLOBALS['cfg_df_style']."/list_default.htm";
    }
   if(!file_exists($tempfile)||!is_file($tempfile)){
    echo "模板文件：'".$tempfile."' 不存在，无法解析文档！";
    exit();
   }
   $this->dtp->LoadTemplate($tempfile);
   $ctag = $this->dtp->GetTag("page");
   if(!is_object($ctag)){ $ctag = $this->dtp->GetTag("list"); }  
  if($ctag->GetAtt("addonid")!="") $this->addonid = $ctag->GetAtt("addonid");
   if(!is_object($ctag)) $this->PageSize = 20;
   else{
     if($ctag->GetAtt("pagesize")!="") {
     $this->PageSize = $ctag->GetAtt("pagesize");
   }
      else $this->PageSize = 20;
    }
 
   //统计数据库记录
   $this->TotalResult = -1;
   if(isset($GLOBALS['TotalResult'])) $this->TotalResult = $GLOBALS['TotalResult'];
   if(isset($GLOBALS['PageNo'])) $this->PageNo = $GLOBALS['PageNo'];
   else $this->PageNo = 1;
   
   if($this->TotalResult==-1)
   {
     $addSql  = " arcrank > -1 ";
     
  if($this->addonid!="") $isaddon = " Or #@__archives.typeid in (".$this->addonid.")";
  else $isaddon = "";
     
     if($cfg_list_son=='否') $addSql .= " And (typeid='".$this->TypeID."' or typeid2='".$this->TypeID."' ".$isaddon.") ";
     else $addSql .= " And (".$this->TypeLink->GetSunID($this->TypeID,"#@__archives",$this->Fields['channeltype'])." Or #@__archives.typeid2='".$this->TypeID."' ".$isaddon.") ";
     
     if($this->StartTime>0) $addSql .= " And senddate>'".$this->StartTime."'";
     $cquery = "Select count(*) as dd From #@__archives where $addSql";
    $row = $this->dsql->GetOne($cquery);
    if(is_array($row)) $this->TotalResult = $row['dd'];
    else $this->TotalResult = 0;
   }
 
    $this->TotalPage = ceil($this->TotalResult/$this->PageSize);
  }

说明，首先把统计数据库记录这部分代码后移，目的是为了利用获得的属性参数addonid，接着通过$this->addonid = $ctag->GetAtt("addonid");获得模板中的addonid的值，然后生成新的统计数据库的sql语句。

第三步，修改function GetArcList()函数，显示文档列表。

原文件为（代码片断）：

  if($cfg_list_son=='否') $orwhere .= " And (arc.typeid='".$this->TypeID."' or arc.typeid2='".$this->TypeID."') ";
  else $orwhere .= " And (".$this->TypeLink->GetSunID($this->TypeID,"arc",$this->Fields['channeltype'])." Or arc.typeid2='".$this->TypeID."') ";

修改为：

  if($this->addonid!="") $isaddon = " Or arc.typeid in (".$this->addonid.")";
  else $isaddon = "";
  if($cfg_list_son=='否') $orwhere .= " And (arc.typeid='".$this->TypeID."' or arc.typeid2='".$this->TypeID."' ".$isaddon.") ";
  else $orwhere .= " And (".$this->TypeLink->GetSunID($this->TypeID,"arc",$this->Fields['channeltype'])." Or arc.typeid2='".$this->TypeID."' ".$isaddon.") ";
