Register.php redirect to previous page?

[Saurdo]

I helped Ludnix out with his question.

Instead of doing this the smart way, which involves putting a hidden value on the registration page and then carrying that value throughout the registration process, I decided to take the easy (and fast) route and use a temporary cookie to store my data.

In register.php, right under this line:

PHP Code:

if ($_REQUEST['do'] == 'signup')
{ 


I put this code:

PHP Code:

setcookie('register_referrer', $_SERVER['HTTP_REFERER'], 0, '/'); 


Might be a good idea to encode the referrer as well.

Then, after the user completes registration. The task is to redirect them to whatever that cookie value is.

So I found this line:

PHP Code:

eval(standard_error(fetch_error('registration_complete', $username, $vbulletin->session->vars['sessionurl'], $vbulletin->options['bburl'] . '/' . $vbulletin->options['forumhome'] . '.php'), '', false)); 


And replaced it with this:

PHP Code:

if(strlen($_COOKIE['register_referrer']) > 0){
                             $vbulletin->url = $_COOKIE['register_referrer']; 
                             eval(print_standard_redirect('registration_complete')); 
                        }
                        else{
                            eval(standard_error(fetch_error('registration_complete', $username, $vbulletin->session->vars['sessionurl'], $vbulletin->options['bburl'] . '/' . $vbulletin->options['forumhome'] . '.php'), '', false));
                        } 


Pretty sure $vbulletin->url is just a header redirect.

If you want, you can then delete your cookie:

PHP Code:

setcookie('register_referrer', '', time()-3000, '/'); 


and everything works and now everyone is happy.
