dedecms上下篇文章的鏈接url地址怎么調(diào)用?

閱讀數(shù)：時間：2018-01-09 來源：發(fā)菜管理系統(tǒng) 標(biāo)簽： dedecms 織夢內(nèi)容管理系統(tǒng)

我們建網(wǎng)站時，有時為了美觀，上下篇文章可能不用文字鏈接的方式來調(diào)用，而是用箭頭圖片的方式來展現(xiàn)。那么就需要修改php程序文件，增加一個上下篇文章的url的標(biāo)簽，因為織夢系統(tǒng)本身帶的上下篇是包含文章標(biāo)題的。請看如果修改的：

打開dedecms系統(tǒng)文件 /include/arc.archives.class.php 按Ctrl+F查找function GetPreNext($gtype='') 即找到GetPreNext函數(shù)（大約在第802行），把整個函數(shù)替換成下面的：

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：沒有了 "; 
        $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：沒有了 "; 
        $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。這樣函數(shù)就修改好了，那么怎么調(diào)用呢？調(diào)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是上一頁鏈接 nexturl是下一頁鏈接當(dāng)值為空時javascript:void; 。把上面紅色部分即上下頁的url根據(jù)你的需要放到相應(yīng)的<a>標(biāo)簽里，就可以實現(xiàn)漂亮的上下翻頁效果啦。
