[SOLVED] form handling redirection?

[coreDev]

Hi everyone 

 

I'm in the process of building a 3 step application, Form 1 -> Form  2 -> Form 3

 

How can i set it for security purposes with PHP that if someone accesses Form 2 or Form 3 directly (ex User goes to www.url.com/form2.php instead of www.url.com/form1.php) that it will redirect them to Page1?

 

Thanks

Start a session, then when goto page 1, set a session variable, say $_SESSION['page'] = 1, then when got page 2 check it for '1', then set to '2', etc...

if not set then use this to redirect:

header('Location: http://www.example.com/');

You could also just use one page, and only display the part of the form that is next, based on that session variable. That way users can't even try to skip ahead.
