透過使用Email驗證啟動的方法，可以有效的幫你阻止惡意的Spam和註冊機器人的存取。
用php寫註冊後Email驗證啟動的步驟非常簡單，相信幾分鐘之內你就能學會。
總共需要兩個頁面，register.php 和verify.php
1. 用戶註冊表格register.php
程式碼如下:
<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>登入後複製
2. 建立使用者資料表Users
程式碼如下：
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 ;
登入後複製
3. 建立驗證碼使用者註冊資訊存入資料表
我們使用狀態' verify' 來表示尚未啟動的使用者。
程式碼如下:
$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')";
登入後複製
4. 傳送驗證碼
# 程式碼如下:
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);登入後複製
5. 驗證啟動程式碼verify.php
如果驗證碼相同，則啟動使用者。
程式碼如下:
$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.";
$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登入後複製
