通過使用Email驗(yàn)證激活的方法，可以有效的幫你阻止惡意的Spam和注冊機(jī)器人的訪問。用php編寫注冊后Email驗(yàn)證激活的步驟非常簡單，相信幾分鐘之內(nèi)你就能學(xué)會。

總共需兩個(gè)頁面，register.php 和 verify.php

1. 用戶注冊表格 register.php

復(fù)制代碼代碼如下:

<html>

<body>

用戶名：<input type="text" name="username" />

密碼：<input type="password" name="password" />

電子郵件：<input type="text" name="email" />

</form>

</body>

</html>

2. 創(chuàng)建用戶數(shù)據(jù)表格 Users

復(fù)制代碼代碼如下:

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. 創(chuàng)建驗(yàn)證碼用戶注冊信息存入數(shù)據(jù)表
我們使用狀態(tài)‘verify' 來表示尚未激活的用戶。

復(fù)制代碼代碼如下:

$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. 發(fā)送驗(yàn)證碼

復(fù)制代碼代碼如下:

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. 驗(yàn)證激活代碼 verify.php
如果驗(yàn)證碼相同，則激活用戶。

復(fù)制代碼代碼如下:

$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.";
