用Php编写注册后Email激活验证的实例代码

2013-03-11 00:00 549 查看
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
