网站选修课作业（4.1）

一：创建一个新的数据库 liuyanban

CREATE DATABASE liuyanban;

二：创建数据库表 message

CREATE TABLE `message` (
  `id` tinyint(1) NOT NULL auto_increment,
  `user` varchar(25) NOT NULL,
  `title` varchar(50) NOT NULL,
  `content` tinytext NOT NULL,
  `lastdate` date NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

三：建立一个数据库连接文件

<?php
/*
 * 
 * @Authors peng--jun 
 * @Email   1098325951@qq.com
 * @Date    2015-05-17 10:53:44
 * @Link    http://www.cnblogs.com/xs-yqz/
 * @version $Id$
 ==========================================
 */
 header("Content-type: text/html; charset=UTF-8"); 
     $DBHOST = 'localhost';
    $DBNAME = 'liuyanban';
    $USER = 'root';
    $PWD= '';
    $conn = mysql_connect($DBHOST,$USER,$PWD) or die ( "连接数据库失败" );
    mysql_select_db ( $DBNAME, $conn ) or die ( "失败" );
?>

四：页面代码

 1 <?php
 2 /*
 3  * 
 4  * @Authors peng--jun 
 5  * @Email   1098325951@qq.com
 6  * @Date    2015-05-17 10:51:56
 7  * @Link    http://www.cnblogs.com/xs-yqz/
 8  * @version $Id$
 9  =====================================================

11  error_reporting(E_ALL ^ E_NOTICE); 
12 include 'include/connectfig.php';//引入头文件
13 if($_POST['submit']){
14     $sql="insert into message(id,user,title,content,lastdate)values('','$_POST[user]','$_POST[title]','$_POST[content]',now())";
15     mysql_query($sql);
16 }
17 ?>
