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：

复制代码
//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：

复制代码
//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();
}
}

易采站长站注释： 其实主要是修改了sql语句

原来的：

复制代码
$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

复制代码
$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
