方法很简单，也是最懒的方法，把关键之处恢复为升级之前的，需要修改两处。

第一处：

修改dede/inc/inc_archives_functions.php

原为：

代码如下: //更新上下篇文章 if($cfg_up_prenext=='Y' && !empty($typeid)) { $preRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And ID>".($aid+10)." And arcrank>-1 And typeid='$typeid' order by ID desc"); $nextRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And ID>".($aid-10)." And arcrank>-1 And typeid='$typeid' order by ID asc"); if(is_array($preRow)){ $arc = new Archives($preRow['ID']); $arc->MakeHtml(); } if(is_array($nextRow)){ $arc = new Archives($nextRow['ID']); $arc->MakeHtml(); } }

改为：

代码如下://更新上下篇文章 if($cfg_up_prenext=='Y' && !empty($typeid)) { $preRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And arcrank>-1 And typeid='$typeid' order by ID desc"); $nextRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And arcrank>-1 And typeid='$typeid' order by ID asc"); if(is_array($preRow)){ $arc = new Archives($preRow['ID']); $arc->MakeHtml(); } if(is_array($nextRow)){ $arc = new Archives($nextRow['ID']); $arc->MakeHtml(); } }

网管之家注释： 其实主要是修改了sql语句

原来的：

代码如下:$preRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And ID>"dede手机模板.($aid+10)." And arcrank>-1 And typeid='$typeid' order by ID desc");$nextRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And ID>".($aid-10)." And arcrank>-1 And typeid='$typeid' order by ID asc");

现在的代码如下: $preRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And arcrank>-1 And typeid='$typeid' order by ID desc"); $nextRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And arcrank>-1 And typeid='$typeid' order by ID asc");

就是将And ID>".($aid+10)." 与And ID>".($aid-10)." 去掉了，为什么id不能大于10呢。如果对于栏目比较多的，肯定不行

第二处：

修改include/inc_archives_view.php

原为：

代码如下: //-------------------------- //获取上一篇，下一篇链接 //--------------------------function GetPreNext($gtype='') { $rs = ""; if(count($this->PreNext)<2) {</p> <p> $aid = $this->ArcID; $idmax = $this->ArcID+10; $idmin = $this->ArcID-10; $next = " arc.ID>'$aid' And arc.ID<'$idmax' And arc.arcrank>-1 And typeid='{$this->Fields['typeid']}' order by arc.ID asc "; $pre = " arc.ID>'$idmin' And arc.ID<'$aid' And arc.arcrank>-1 And typeid='{$this->Fields['typeid']}' order by arc.ID desc "; $query = "Select arc.ID,arc.title,arc.shorttitle, arc.typeid,arc.ismake,arc.senddate,arc.arcrank,arc.money, t.typedir,t.typename,t.namerule,t.namerule2,t.ispart, t.moresite,t.siteurl from `{$this->MainTable}` arc left join dede_arctype t on arc.typeid=t.ID where "; $nextRow = $this->dsql->GetOne($query.$next); $preRow = $this->dsql->GetOne($query.$pre); if(is_array($preRow)) { $mlink = GetFileUrl($preRow['ID'],$preRow['typeid'],$preRow['senddate'],$preRow['title'],$preRow['ismake'],$preRow['arcrank'],$preRow['namerule'],$preRow['typedir'],$preRow['money'],true,$preRow['siteurl']); $this-&dede网站模板gt;PreNext['pre'] = "上一篇：<a href='$mlink' target='_blank'>{$preRow['title']}</a> "; } else{ $this->PreNext['pre'] = "上一篇：没有了 "; } if(is_array($nextRow)) { $mlink = GetFileUrl($nextRow['ID'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'],$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],true,$nextRow['siteurl']); $this->PreNext['next'] = "下一篇：<a href='$mlink' target='_blank'>{$nextRow['title']}</a> "; } else{ $this->PreNext['next'] = "下一篇：没有了 "; } }</p> <p> if($gtype=='pre'){ $rs = $this->PreNext['pre']; } else if($gtype=='next'){ $rs = $this->PreNext['next']; } else{ $rs = $this->PreNext['pre']." &nbsp; ".$this->PreNext['next']; }</p> <p> return $rs; }
