Question

无论如何在PHP中没有表单的情况下获取用户的电子邮件？我希望能够向某人发送邮件列表的电子邮件，而不是填写他们输入电子邮件的表单，我在电子邮件中链接的php页面。他们点击链接，然后将其发送到网站上的感谢页面。然后它将他们的IP，日期/时间和电子邮件存储在我设置的数据库中。我已经用表格填写了这个，但我想知道是否有任何可能的方法可以在没有表格的情况下完成。这是我的表单代码，我使用的是Drupal表单API。我已经谷歌搜索了几个小时，但什么都没发现。我看到了一些关于URL参数的内容，但它并没有真正与我的问题有关。任何帮助表示赞赏。

根据您的评论，听起来您尝试将已知的电子邮件地址与IP地址相关联。您说您正在发送电子邮件，他们正在点击链接。我假设每个电子邮件上的每个链接都是唯一生成的，与特定地址相关联。在这种情况下，您的问题归结为＆＃34;如何找到客户端的IP地址？＆＃34;。

在PHP中，您可以使用$_SERVER['REMOTE_ADDR']执行此操作。这是最可靠的，但绝不是万无一失的。

＆＃39; REMOTE_ADDR＆＃39; 用户正在查看当前页面的IP地址。

如果用户位于代理后面，则可能已设置$_SERVER['HTTP_X_FORWARDED_FOR']，但客户端和代理可能会欺骗此值。它不能保证准确，也不应该被信任。但是，如果用户使用代理，REMOTE_ADDR中的值将是访问您的网络服务器的代理的IP地址，而不是客户端的IP地址。

因此，假设您要使用REMOTE_ADDR，如何将电子邮件地址与IP地址相关联？

用户单击您使用已知电子邮件地址存储的唯一链接。该链接运行一个非常简单的脚本，并查看REMOTE_ADDR和HTTP_X_FORWARDED_FOR并存储这两个值。

你的桌子应该像这样简单：

email_address | unique_link | remote_addr | http_x_forwarded_for

用户点击unique_link后，会填写最后两个值。你最初如何填充email_address仍然是你的秘密。
