无忧主机在这里介绍一下关于织梦dedecms v5.1升级sp1后不显示上一篇、下一篇问题,需要的朋友可以参考下,主要就是不懂官方为什么加个id限制。

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:

//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:

//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();

}

}

脚本之家注释: 其实主要是修改了sql语句

原来的:

$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”);

现在的

$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:

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 “;

$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’]);

$this->PreNext[‘pre’] = “上一篇:<a href=’$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;

}

function GetPreNext($gtype=”)

{

$rs = “”;

if(count($this->PreNext)<2)

{</p> <p> $aid = $this->ArcID;

$idmax = $this->ArcID+10;

$idmin = $this->ArcID-10;

$nextRow = $this->dsql->GetOne($query.$next);

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’]);

else{

$this->PreNext[‘pre’] = “上一篇:没有了 “;

if(is_array($nextRow))

}

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;

}

改好的文件覆盖上传即可,为了保险起见,最好是复制一份。

当然这里也是修改的sql语句

$next = ” arc.ID>’$aid’ And arc.arcrank>-1 And typeid='{$this->Fields[‘typeid’]}’ order by arc.ID asc “;

$pre = ” arc.ID<‘$aid’ And arc.arcrank>-1 And typeid='{$this->Fields[‘typeid’]}’ order by arc.ID desc “;

因为可能版本不同,不建议直接全部复制,只需要替换下sql语句即可。要不容易出现错误。
