用Php编写注册后Email激活验证的实例代码

时间：2021-05-18

总共需两个页面，register.php 和 verify.php

1. 用户注册表格 register.php

复制代码 代码如下:
<html>

<body>

<form action="register.php" method="post" name="register">

用户名：<input type="text" name="username" />

密码：<input type="password" name="password" />

电子邮件：<input type="text" name="email" />

<input type="submit" value="注册" />

</form>

</body>

</html>

2. 创建用户数据表格 Users
复制代码 代码如下:
CREATE TABLE IF NOT EXISTS `users` (

`id` int(11) NOT NULL auto_increment,

`status` varchar(20) NOT NULL,

`username` varchar(20) NOT NULL,

`password` varchar(20) NOT NULL,

`email` varchar(20) NOT NULL,

`activationkey` varchar(100) NOT NULL,

PRIMARY KEY (`id`),

UNIQUE KEY `username` (`username`),

UNIQUE KEY `email` (`email`),

UNIQUE KEY `activationkey` (`activationkey`)

) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=9 ;

3. 创建验证码 用户注册信息存入数据表
我们使用状态‘verify' 来表示尚未激活的用户。

复制代码 代码如下:
$activationKey = mt_rand() . mt_rand() . mt_rand() . mt_rand() . mt_rand();

$username = mysql_real_escape_string($_POST[username]);

$password = mysql_real_escape_string($_POST[password]);

$email = mysql_real_escape_string($_POST[email]);

$sql="INSERT INTO users (username, password, email, activationkey, status) VALUES ('$username', '$password', '$email', '$activationKey', 'verify')";

4. 发送验证码
复制代码 代码如下:
echo "An email has been sent to $_POST[email] with an activation key. Please check your mail to complete registration.";

##Send activation Email

$to = $_POST[email];

$subject = " YOURWEBSITE.com Registration";

$message = "Welcome to our website!\r\rYou, or someone using your email address, has completed registration at YOURWEBSITE.com. You can complete registration by clicking the following link:\rhttp:// account.";

$sql="UPDATE users SET activationkey = '', status='activated' WHERE (id = $row[id])";

if (!mysql_query($sql)) {

die('Error: ' . mysql_error());

}

// 到这里，用户已经完全激活了账号，你可以将页面跳转到登陆后的界面了

}

} // end of while
