用Php编写注册后Email激活验证的实例代码

2015-01-24信息快讯网

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
