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
<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
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。
$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
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。
$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
