用Php编写注册后Email激活验证的实例代码

总共需两个页面，register.PHP 和 verify.PHP

1. 用户注册表格 register.PHP

代码如下:

PHP" method="post" name="register">

用户名：

密码：

电子邮件：

2. 创建用户数据表格 Users

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。

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

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";

$message = "Welcome to our website!\r\rYou,or someone using your email address,has completed registration at YOURWEBSITE.com. You can complete registration by clicking the following link:\rhttp://www.YOURWEBSITE.com/verify.PHP?$activationKey\r\rIf this is an error,ignore this email and you will be removed from our mailing list.\r\rRegards,\ YOURWEBSITE.com Team";

$headers = 'From: noreply@ YOURWEBSITE.com' . "\r\n" .

'Reply-To: noreply@ YOURWEBSITE.com' . "\r\n" .

'X-Mailer: PHP/' . PHPversion();

mail($to,$subject,$message,$headers);

5. 验证激活代码 verify.PHP
如果验证码相同，则激活用户。

代码如下:

$queryString = $_SERVER['QUERY_STRING'];

$query = "SELECT * FROM users";

$result = MysqL_query($query) or die(MysqL_error());

while($row = MysqL_fetch_array($result)){

if ($queryString == $row["activationkey"]){

echo "Congratulations!" . $row["username"] . " is Now the proud new owner of a YOURWEBSITE.com 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
