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

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：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode7" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
//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(); 
} 
}</div>



改为：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode8" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
//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(); 
} 
}</div>



注释：其实主要是修改了sql语句

原来的：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode9" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
$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");</div>



现在的 

<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode10" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
$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");</div>



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：


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode11" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>

改好的文件覆盖上传即可。

当然这里也是修改的sql语句


<div class="msgheader" style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div class="right">
复制代码
</div>
代码如下:</div>
<div class="msgborder" id="phpcode13" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
 
$next = " arc.ID>'$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 ";</div>



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。
