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($this->TypeID,"dede_archives",$this->Fields[‘channeltype’])." Or dede_archives.typeid2=’".$this->TypeID."’) "; if($this->StartTime>0) $addSql .= " And senddate>’".$this->StartTime."’"; $cquery = "Select count(*) as dd From dede_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!="") $isaddon = " Or dede_archives.typeid in (".$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($this->TypeID,"dede_archives",$this->Fields[‘channeltype’])." Or dede_archives.typeid2=’".$this->TypeID."’ ".$isaddon.") "; if($this->StartTime>0) $addSql .= " And senddate>’".$this->StartTime."’"; $cquery = "Select count(*) as dd From dede_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.") ";
人生的大部份时间里，承诺同义词是束缚，奈何我们向往束缚。
