Paypal Return Value Question

<input type="hidden" name="return" 
    value="<?=$cfg->wwwroot."registration-confirmed-".base64_encode(serialize(array($user->id, 1)))?>">

You should use PDT (Payment Data Transfer) for this purpose.

This reference should be helpful. There are instructions on activating PDT at the bottom of the page.

Once you've setup PDT, simply change your input's name from 'return' to 'custom'.

In your code, which reads PDT data (thankyou.php), issue a redirect to 'custom' value that you'll get from Paypal PDT data. Example PHP script for PDT is here.
