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'/}
