通过电子邮件验证链接 [英] validation link via email

问题描述

当用户通过电子邮件地址订阅我的简报时，使用php，我如何通过电子邮件向他们发送激活链接，以确认它是他们的电子邮件地址，而不是假的。

When a user subscribes to my newsletter via their email address, using php, how would I send them an 'Activation Link' via email to confirm it is their email address and not a fake one.

所以现在我有

PHP：

<?php
 $to = "[e-mail]";
 $subject = "Hi!";
 $body = "Hi,\n\nHow are you?";
 if (mail($to, $subject, $body)) {
   echo "<p>Message successfully sent!</p>";
  } else {
   echo "<p>Message delivery failed...</p>";
  }
 ?>

我想我会将$ body更改为：

I guess i would change the $body to this:

$body = "Please click the link to activate your email \n
http://www.activationlink.com?";

我如何做到这一点，如果用户点击该链接会将其详细信息添加到Mysql数据库识别他们是合法用户？

How would I make it so that if a user clicked that link it would add their details to the Mysql database recognising they are a legitimate subscriber?

任何帮助或建议赞赏。谢谢

Any help or suggestions appreciated. Thanks

推荐答案

我喜欢做的是：

• 在注册过程中生成唯一的随机ID

• Generate a unique, random ID in the registration process

将ID与电子邮件地址一起存储，已确认字段（默认值：否）和数据库表中的任何其他数据

Store the ID along with the E-Mail address, a "confirmed" field (default: "no") and any additional data in a database table

发送电子邮件带有指向要激活唯一ID的URL （例如 domain.com/activate.php?id=102939505595

Send out the E-Mail with an URL pointing to activate the unique ID (e.g. domain.com/activate.php?id=102939505595

激活页面检查是否存在唯一键，并将确认字段更改为是（或 1

The activation page checks whether the unique key exists and changes the confirmed field to yes (or 1 or whatever).

此外，可选地，保存确认日期/时间，IP地址和用户代理。

Additionally and optionally, save the confirmation date/time, IP address and user agent.
