这是一个最基础的留言板程序了,但是己经有了留言板程序基本功能,很适合于php初学者用用,学习用啊,当然也可以用于企业网站也是很不错的哦。

 

 代码如下 复制代码

session_start();
$con=mysql_connect('localhost','root','root') or die('链接数据库失败!');
mysql_query('set names utf8');
mysql_select_db('GuestBook');

$pagesize = 10;//每一页显示多少留言记录
if(isset($_GET['page'])&&$_GET['page']!='') $page=$_GET['page'];
else $page=0;

$sql = "SELECT a . * , b.name, b.email, b.qq, c.revert_time, c.revert
  FROM post a
  LEFT JOIN revert c ON ( a.id = c.post_id ) , guest b
  WHERE a.guest_id = b.id
  ORDER BY a.id DESC";
$numRecord = mysql_num_rows(mysql_query($sql));
$totalpage = ceil($numRecord/$pagesize);

$recordSql = $sql. " LIMIT ".$page*$pagesize.",".$pagesize;
$result = mysql_query($recordSql);
?>
