织梦dedecms v5.1升级sp1后不显示上一篇、下一篇问题的解决方法

  dede织梦

  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<$aid And ID>“.($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)   {

  

$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’]);

  $this->PreNext[‘pre’] = “上一篇:{$preRow[‘title’]} “;

  }

  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’]);

  $this->PreNext[‘next’] = “下一篇:{$nextRow[‘title’]} “;

  }

  else{

  $this->PreNext[‘next’] = “下一篇:没有了 “;

  }

  }

  

if($gtype==’pre’){

  $rs = $this->PreNext[‘pre’];

  }

  else if($gtype==’next’){

  $rs = $this->PreNext[‘next’];

  }

  else{

  $rs = $this->PreNext[‘pre’].”   “.$this->PreNext[‘next’];

  }

  

return $rs;

  }

  改为:

  代码如下:

  //————————–

  //获取上一篇,下一篇链接

  //————————–

  function GetPreNext($gtype=”)

  {

  $rs = “”;

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

  

$aid = $this->ArcID;

  $idmax = $this->ArcID+10;

  $idmin = $this->ArcID-10;

  $next = ” arc.ID>’$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 “;

  $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’]);

  $this->PreNext[‘pre’] = “上一篇:{$preRow[‘title’]} “;

  }

  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’]);

  $this->PreNext[‘next’] = “下一篇:{$nextRow[‘title’]} “;

  }

  else{

  $this->PreNext[‘next’] = “下一篇:没有了 “;

  }

  }

  

if($gtype==’pre’){

  $rs = $this->PreNext[‘pre’];

  }

  else if($gtype==’next’){

  $rs = $this->PreNext[‘next’];

  }

  else{

  $rs = $this->PreNext[‘pre’].”   “.$this->PreNext[‘next’];

  }

  

return $rs;

  }

  改好的文件覆盖上传即可。

  当然这里也是修改的sql语句

  代码如下:

  $next = ” arc.ID>’$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 “;
