I have had a look around, but the closest I found was for asp.net. I would like to prevent the user from pressing the back button in the browser, or if possible link him to a different page if he does press the back button.
Page 1: Register Page 2: Register Complete When the user presses back it should redirect him to the homepage (home.html).
All help is welcome!
You can't prevent him from using back. Period. Even when you open a popup and hiding the navigation buttons it can be circumvented.
What you could do, when the user is registered, set a cookie or store something in $_SESSION, and if the user is registered ($_SESSION['justRegistred'] = true), you can check that if that value exists when on Page 1. If the value exists and is true, do a header_location('.../home.php')
