= isset($_GET['id']) > 0 ? intval($_GET['id']) : ""; 下一篇文章   $query = mysql_query("SELECT id,title FROM article WHERE id>'$id' ORDER BY id ASC LIMIT 1");   $next = mysql_fetch_array($query); 上一篇文章   $query = mysql_query("SELECT id,title FROM article WHERE id <'$id' ORDER BY id DESC LIMIT 1");   $prev = mysql_fetch_array($query); 页面显示上一篇和下一篇文章标题和链接 <div class="page_nav clearfix"> <div title="下一篇" class="next_page"> <a href="?id=<?php echo $next['id']; ?>"><?php echo $next['title']; ?></a> </div> <div title="上一篇" class="pre_page"> <a href="?id=<?php echo $prev['id']; ?>"><?php echo $prev['title']; ?></a> </div> </div>

<?php

  //基于thinkPHP框架

  $up = M('Content')->where(array('id' => array('gt',$id),'del'=>1,'cid'=>$cont['cid']))
         ->order('id asc')->find();
  $this -> assign('up',$up);//上一篇

  $dw = M('Content')->where(array('id' => array('lt',$id),'del'=>1,'cid'=>$cont['cid']))
	 ->order('id desc')->find();
  $this -> assign('dw',$dw);//下一篇
?>
