对于列车上的人来说，我们这些仰躺着望天的孩子只是呼啸而过的风景他们却不知到这些孩子曾偷偷的哭过多少回。
大家都知道DedeCMS从5.5版本之后加入图集功能，调用起来很方便，其中 {dede:prenext get='nextimg'/} {dede:prenext get='preimg'/} 就是上下页链接，可以显示图片的，可是我想要的功能是做一个图片幻灯类似于新浪的那种。就是“上一图集”“下一图集”的样子。
织梦不带有这个功能，需要我们自己来扩展。
打开include/arc.archives.class.php文件，修改GetPreNext() ，以下区域红色代码是新增加的。
//获取上一篇，下一篇链接
function GetPreNext($gtype='')
{
$rs = '';
if(count($this->PreNext)<2)
{
$aid = $this->ArcID;
$preR = $this->dsql->GetOne("Select id From `q_arctiny` where id<$aid And arcrank>-1 And typeid='{$this->Fields['typeid']}' order by id desc");
$nextR = $this->dsql->GetOne("Select id From `q_arctiny` where id>$aid And arcrank>-1 And typeid='{$this->Fields['typeid']}' order by id asc");
$next = (is_array($nextR) ? " where arc.id={$nextR['id']} " : ' where 1>2 ');
$pre = (is_array($preR) ? " where arc.id={$preR['id']} " : ' where 1>2 ');
$query = "Select arc.id,arc.title,arc.shorttitle,arc.typeid,arc.ismake,arc.senddate,arc.arcrank,arc.money,arc.filename,arc.litpic,
t.typedir,t.typename,t.namerule,t.namerule2,t.ispart,t.moresite,t.siteurl,t.sitepath
from `q_archives` arc left join q_arctype t on arc.typeid=t.id ";
$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'],$preRow['money'],$preRow['filename'],$preRow['moresite'],$preRow['siteurl'],$preRow['sitepath']);
$this->PreNext['pre'] = "上一篇：<a rel="nofollow noopener noreferrer" href='$mlink'>{$preRow['title']}</a> ";
$this->PreNext['preimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$preRow['litpic']}\&; alt=\&;{$preRow['title']}\&;/></a> ";
$this->PreNext['pretj'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><<上一图集</a> ";
}
else
{
$this->PreNext['pre'] = "上一篇：没有了 ";
$this->PreNext['preimg'] ="<img src=\&;/templets/default/images/nophoto.jpg\&; alt=\&;对不起，没有上一图集了！\&;/>";
$this->PreNext['pretj'] = "<a rel="nofollow noopener noreferrer" href='$mlink'>没有了</a> ";
}
if(is_array($nextRow))
{
$mlink = GetFileUrl($nextRow['id'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'],
$nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']);
$this->PreNext['next'] = "下一篇：<a rel="nofollow noopener noreferrer" href='$mlink'>{$nextRow['title']}</a> ";
$this->PreNext['nextimg'] = "<a rel="nofollow noopener noreferrer" href='$mlink'><img src=\&;{$nextRow['litpic']}\&; alt=\&;{$nextRow['title']}\&;/></a> ";
$this->PreNext['nexttj'] = "<a rel="nofollow noopener noreferrer" href='$mlink'>下一图集>></a> ";
}
else
{
$this->PreNext['next'] = "下一篇：没有了 ";
$this->PreNext['nextimg'] ="<a rel="nofollow noopener noreferrer" href='javascript：void(0)' alt=\&;\&;><img src=\&;/templets/default/images/nophoto.jpg\&; alt=\&;对不起，没有下一图集了！\&;/></a>";
$this->PreNext['nexttj'] = "<a rel="nofollow noopener noreferrer" href='$mlink'>没有了</a> ";
}
}
if($gtype=='pre')
{
$rs = $this->PreNext['pre'];
}
else if($gtype=='preimg'){
$rs = $this->PreNext['preimg'];
}
else if($gtype=='pretj'){
$rs = $this->PreNext['pretj'];
}
else if($gtype=='next')
{
$rs = $this->PreNext['next'];
}
else if($gtype=='nextimg'){
$rs = $this->PreNext['nextimg'];
}
else if($gtype=='nexttj'){
$rs = $this->PreNext['nexttj'];
}
else
{
$rs = $this->PreNext['pre']." ".$this->PreNext['next'];
}
return $rs;
}

调用的时候写成这样即可： 上一图集：{dede:prenext get='pretj'/} 下一图集：{dede:prenext get='nexttj'/}
