只允许查看从 example.com/login 重定向的页面

Question

I want a page that can be only accessible who is redirected from example.com/login

As example, if I directly visit example.com/alice.php it will redirect me to an error page. example.com/alice.php can be only accessible if a visitor was redirected from example.com/login .

How can I do that with php?

Answer 1

perhaps you can use this as:

<?php
//your-url-which-you-do-not-what-direct access
$url != 'http://example.com/alice.php';

if ($_SERVER['HTTP_REFERER'] == $url) {
  header('Location: http://example.com/error.php'); //redirect to some other page
  exit();
}

?>
