实现让DeDecms的上下文章链接限制在当前栏目内
作者:
使用dedecms的时候,当打开某篇文章的时候,底部会有“上一篇”“下一篇”的链接信息,默认情况下,上下链接信息并没有区分栏目的属性,那么需要实现本栏目内的上下篇,如何实现呢?
基本思路:实现上下文章链接的函数位于GetPreNext(),我们在这个函数中获得栏目ID,然后修改SQL语句,在查询数据库的时候加上栏目ID的限制。
修改方法:
找到include/inc_archives_view.php中的function GetPreNext()函数,修改为:
//--------------------------
//获取上一篇,下一篇链接
//--------------------------
function GetPreNext()
{
$rs = "";
$aid = $this->ArcID;
$rid = $this->Fields['typeid'];
$next = " #@__archives.ID>'$aid' and #@__archives.typeID='$rid' order by #@__archives.ID asc ";
$pre = " #@__archives.ID<'$aid' and #@__archives.typeID='$rid' order by #@__archives.ID desc ";
//$next = " #@__archives.ID>'$aid' order by #@__archives.ID asc ";
//$pre = " #@__archives.ID<'$aid' order by #@__archives.ID desc ";
$query = "Select #@__archives.ID,#@__archives.title,
#@__archives.typeid,#@__archives.ismake,#@__archives.senddate,#@__archives.arcrank,#@__archives.money,
#@__arctype.typedir,#@__arctype.typename,#@__arctype.namerule,#@__arctype.namerule2,#@__arctype.ispart,
#@__arctype.moresite,#@__arctype.siteurl
from #@__archives left join #@__arctype on #@__archives.typeid=#@__arctype.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']);
$rs .= "上一篇:<a href='$mlink'>{$preRow['title']}</a> ";
}
else{
$rs .= "上一篇:没有了 ";
}
if(is_array($nextRow)){
$mlink = GetFileUrl($nextRow['ID'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'],$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],true,$nextRow['siteurl']);
$rs .= " 下一篇:<a href='$mlink'>{$nextRow['title']}</a> ";
}
else{
$rs .= " 下一篇:没有了 ";
}
return $rs;
}
如果你不会修改,还可以下载修改后的:inc_archives_view.php。
