導讀:DEDE技術DEDE技術這篇文章主要介紹了織夢dedecms v5.1升級sp1后不顯示上一篇、下一篇問題的解決方法,需要的朋友可以參考下，主要就是不懂官方為什么加個id限制織夢模板安裝dede手機模板。

dede織夢

方法很簡單，也是最懶的方法，把關鍵之處恢復為升級之前的，需要修改兩處。

第一處：

修改dede/inc/inc_archives_functions.php

原為：

代碼如下: //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(); } }

改為：

代碼如下://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(); } }

網管之家注釋： 其實主要是修改了sql語句

原來的：

代碼如下:$preRow = $arc->dsql->GetOne("Select ID From `{$arc->MainTable}` where ID<$aid And ID>"dede手機模板.($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");

現在的代碼如下: $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");

就是將And ID>".($aid+10)." 與And ID>".($aid-10)." 去掉了，為什么id不能大于10呢。如果對于欄目比較多的，肯定不行

第二處：

修改include/inc_archives_view.php

原為：

代碼如下: //-------------------------- //獲取上一篇，下一篇鏈接 //--------------------------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']); $this-&dede網站模板gt;PreNext['pre'] = "上一篇：<a href='$mlink' target='_blank'>{$preRow['title']}</a> "; } else{ $this->PreNext['pre'] = "上一篇：沒有了 "; } if(is_array($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{ $this->PreNext['next'] = "下一篇：沒有了 "; } }</p> <p> if($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; }
