1.创建数据库`lyb`
CREATE DATABASE `lyb`;
CREATE TABLE `lyb1` ( id INT NOT NULL AUTO_INCREMENT , title VARCHAR( 200 ) NOT NULL , content TEXT NOT NULL , author VARCHAR( 30 )not null DEFAULT ‘彭军‘, email VARCHAR( 40 ) not null DEFAULT ‘[email protected]‘, PRIMARY KEY ( id ) , UNIQUE (title) ) ENGINE = INNODB DEFAULT CHARSET = utf8
数据库连接文件conn.php
header("Content-type: text/html; charset=UTF-8");
$DB_SERVER = "localhost";
$DB_NAME = "root";
$DB_PWD = "";
$conn = mysql_connect($DB_SERVER,$DB_NAME,$DB_PWD);
if (!$conn) {
die("连接数据库失败".mysql_errno());
}
mysql_query("set names utf8");
2.建立前台页面 5.1.php
<?php
/*
*
* @Authors peng--jun
* @Email [email protected]
* @Date 2015-11-07 13:50:48
* @Link http://www.cnblogs.com/xs-yqz/
* @version $Id$
==========================================
*/
header("Content-type: text/html; charset=UTF-8");
if (isset($_POST[‘submit‘])) {
require("include/conn.php");
mysql_select_db("lyb",$conn);//选择数据库
$title = $_POST[‘title‘];
$author = $_POST[‘author‘];
$content = $_POST[‘content‘];
$email = $_POST[‘email‘];
$result = mysql_query("insert into `lyb1`(`id`,`title`,`content`,`author`,`email`) values(null,‘$title‘,‘$content‘,‘$author‘,‘$email‘)");
var_dump($result);
mysql_free_result($result);
mysql_close($result);
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>添加数据页面</title>
</head>
<body>
<form action="5.1.php" method="POST">
<p>添加新闻页面</p>
<div>标题:<input type="text" name="title" id=""></div>
<div>内容: <textarea name="content" id="" cols="30" rows="5"></textarea></div>
<div>作者:<input type="text" name="author" id=""></div>
<div>邮箱:<input type="text" name="email" id=""></div>
<div><input type="reset" value="重置"><input type="submit" name="submit" value="提交"></div>
</form>
</body>
</html>
3.从数据库中获取数据显示在前台页面
<?php
/*
*
* @Authors peng--jun
* @Email [email protected]
* @Date 2015-11-07 13:40:08
* @Link http://www.cnblogs.com/xs-yqz/
* @version $Id$
==========================================
*/
header("Content-type: text/html; charset=UTF-8");
require("include/conn.php");
mysql_select_db("lyb",$conn);//选择数据库
$result = mysql_query("select * from `lyb1`",$conn);//选择数据库表
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>新闻显示页面</title>
</head>
<body>
<table border="1">
<tr bgcolor="#ccc">
<th>序号</th>
<th>标题</th>
<th>内容</th>
<th>作者</th>
<th>邮箱</th>
</tr>
<?php
while ($row = mysql_fetch_assoc($result)) {
?>
<tr>
<td><?= $row[‘id‘]?></td>
<td><?= $row[‘title‘]?></td>
<td><?= $row[‘content‘]?></td>
<td><?= $row[‘author‘]?></td>
<td><?= $row[‘email‘]?></td>
</tr>
<?php
}
?>
</table>
<p>共有<?= mysql_num_rows($result) ?>条记录 </p>
<!-- mysql_num_rows（）函数返回的是结果集的总数 -->
<?php
//释放资源，关闭结果集
mysql_free_result($result);
mysql_close($result);
?>
</body>
</html>
