用Php编写注册后Email激活验证的实例代码_PHP

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:
 

 

  

      用户名：

      密码：

      电子邮件：

     

  

 

 

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";

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

复制代码 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
