Question

I have a web site with several pages. Page1, Page2, .. etc

I don’t want the user to visit Page2 posting its URL directly in the browser because Page2 should be visited only from Page1. In PHP, what should I code in Page2 to know that the user was before in Page1 and clicked a link or something that brough him or her to Page2? Thanks.

Answer 1

You could use PHP sessions.

page1.php

session_start();
$_SESSION['pages_visited'][basename(__FILE__)] = true;

page2.php

session_start();
$_SESSION['pages_visited'][basename(__FILE__)] = true;

if (!isset($_SESSION['pages_visited']['page1.php']) || !$_SESSION['pages_visited']['page1.php']) {
    header('Location: page1.php');
    exit;
}
