dedecms上下篇文章的链接url地址怎么调用?

阅读数：时间：2018-01-09 来源：发菜管理系统标签： dedecms 织梦内容管理系统

我们建网站时，有时为了美观，上下篇文章可能不用文字链接的方式来调用，而是用箭头图片的方式来展现。那么就需要修改php程序文件，增加一个上下篇文章的url的标签，因为织梦系统本身带的上下篇是包含文章标题的。请看如果修改的：

打开dedecms系统文件 /include/arc.archives.class.php 按Ctrl+F查找function GetPreNext($gtype='') 即找到GetPreNext函数（大约在第802行），把整个函数替换成下面的：

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']); 
        $this->PreNext['pre'] = "上一篇：<a  data-cke-saved-href='$mlink' href='$mlink'>{$preRow['title']}</a> "; 
        $this->PreNext['preurl']=$mlink; 
        $this->PreNext['preimg'] = "<a  data-cke-saved-href='$mlink' href='$mlink'><img  data-cke-saved-src= src="{$preRow['litpic']}"
      } 
      else 
      { 
        $this->PreNext['pre'] = "上一篇：没有了 "; 
        $this->PreNext['preurl'] = "javascript:void:"; 
        $this->PreNext['preimg'] ="<img  data-cke-saved-src= src="/templets/default/images/nophoto.jpg"     } 
      if(is_array($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']); 
        $this->PreNext['next'] = "下一篇：<a  data-cke-saved-href='$mlink' href='$mlink'>{$nextRow['title']}</a> "; 
        $this->PreNext['nexturl']=$mlink; 
        $this->PreNext['nextimg'] = "<a  data-cke-saved-href='$mlink' href='$mlink'><img  data-cke-saved-src= src="{$nextRow['litpic']}"     } 
      else 
      { 
        $this->PreNext['next'] = "下一篇：没有了 "; 
        $this->PreNext['nexturl'] = "javascript:void:"; 
        $this->PreNext['nextimg'] ="<a  data-cke-saved-href='javascript:void(0)' href='javascript:void(0)'data-cke-saved-src= src="/templets/default/images/nophoto.jpg"     } 
    } 
    if($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; 
  }

然后保存。这样函数就修改好了，那么怎么调用呢？调用方法：

<li><a href="{dede:prenext get='preurl'/}" class="pr"><</a></li>
<li><a href="{dede:prenext get='nexturl'/}" class="pr">></a></li>

preurl是上一页链接 nexturl是下一页链接当值为空时javascript:void; 。把上面红色部分即上下页的url根据你的需要放到相应的<a>标签里，就可以实现漂亮的上下翻页效果啦。
