在使用dedecms做网站开发时,会用到在内页单独调用上一页\\下一页代码的链接地址,具体步骤如下:
第一步:打开织梦系统文件/include/arc.archives.class.php
找到GetPreNext函数;
把之前的代码替换为以下提供的代码即可:
function GetPreNext($gtype='') { $rs = ''; if(count($this->PreNext)<2) { $aid = $this->ArcID; $preR = $this->dsql->GetOne("Select id From `dede_arctiny` where id<$aid And arcrank>-1 And typeid='{$this->Fields['typeid']}' order by id desc"); $nextR = $this->dsql->GetOne("Select id From `dede_arctiny` where id>$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 `dede_archives` arc left join dede_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> "; $this->PreNext['preurl']=$mlink; $this->PreNext['preimg'] = "<a href='$mlink'><img src=\\"{$preRow['litpic']}\\" alt=\\"{$preRow['title']}\\"/></a> "; } else { $this->PreNext['pre'] = "上一篇:没有了 "; $this->PreNext['preurl'] = "javascript:void:"; $this->PreNext['preimg'] ="<img src=\\"/templets/default/images/nophoto.jpg\\" alt=\\"对不起,没有上一图集了!\\"/>"; } if(is_array($nextRow)) { $mlink = GetFileUrl($nextRow['id'],$nextRow['typeid'],$nextRow['senddate'],$nextRow['title'],$nextRow['ismake'],$nextRow['arcrank'], $nextRow['namerule'],$nextRow['typedir'],$nextRow['money'],$nextRow['filename'],$nextRow['moresite'],$nextRow['siteurl'],$nextRow['sitepath']); $this->PreNext['next'] = "下一篇:<a href='$mlink'>{$nextRow['title']}</a> "; $this->PreNext['nexturl']=$mlink; $this->PreNext['nextimg'] = "<a href='$mlink'><img src=\\"{$nextRow['litpic']}\\" alt=\\"{$nextRow['title']}\\"/></a> "; } else { $this->PreNext['next'] = "下一篇:没有了 "; $this->PreNext['nexturl'] = "javascript:void:"; $this->PreNext['nextimg'] ="<a href='javascript:void(0)' alt=\\"\\"><img src=\\"/templets/default/images/nophoto.jpg\\" alt=\\"对不起,没有下一图集了!\\"/></a>"; } } if($gtype=='pre') { $rs = $this->PreNext['pre']; } else if($gtype=='preimg'){ $rs = $this->PreNext['preimg']; } else if($gtype=='next') { $rs = $this->PreNext['next']; } else if($gtype=='nextimg'){ $rs = $this->PreNext['nextimg']; } else if($gtype=='preurl'){ $rs = $this->PreNext['preurl']; }else if($gtype=='nexturl'){ $rs = $this->PreNext['nexturl']; } else{ $rs = $this->PreNext['pre']." ".$this->PreNext['next']; } return $rs; }
第二步:文件替换好了,那就可以调用的了,调用标签如下:
-
上一篇链接:{dede:prenext get='preurl'/}
-
下一篇链接:{dede:prenext get='nexturl'/}
