I'm trying to set up the Registration link, allowing visitors to go from a Workshop to a registration form, which than should have relevant info already included in the input fields.
But nothing happens.
The $RegistrationLink in the CMS reads "registration" (e.g. the name of the form function in forms.php), followed by ?id=917, which is the id shown in the CMS (admin/show/917). Also tried to pass it with $MenuTitle instead of id, even with entire URL, but without success.
Is there any chance to pass the data into the form, when visitors click the registration link ?
