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']);
$this->PreNext['pre'] = 上一篇:<a href='$mlink'>{$preRow['title']}</a> ;
$this->PreNext['preimg'] = <a href='$mlink'><img src={$preRow['litpic']} alt={$preRow['title']}/></a> ;
$this->PreNext['pretj'] = <a href='$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!/>;
$this->PreNext['pretj'] = <a href='$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']);
$this->PreNext['next'] = 下一篇:<a href='$mlink'>{$nextRow['title']}</a> ;
$this->PreNext['nextimg'] = <a href='$mlink'><img src={$nextRow['litpic']} alt={$nextRow['title']}/></a> ;
$this->PreNext['nexttj'] = <a href='$mlink'>下一图集>></a> ;
}
else
{
$this->PreNext['next'] = 下一篇:没有了 ;
$this->PreNext['nextimg'] =<a href='javascript:void(0)' alt=><img src=/templets/default/images/nophoto.jpg alt=对不起,没有下一图集了!/></a>;
$this->PreNext['nexttj'] = <a href='$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'/}
