We're using gravity forms on a university website. My idea is a little complex, so hopefully it'll make sense.
On our old non-Wordpress website, we'd make forms using PHP and include a file at the top called auth.php. When we include that file, it requires people to login with their university ID before they could see the page. Once logged in, it would show the page. We'd also be able to grab the ID and put it in a read-only field so that people could only submit once.
Is this scenario possible, and if so, does anyone have any ideas on how to make it happen: I'd like to make it so that if anyone creates a field called "AuthID", it would automatically make the form software include the auth.php file so that people would have to log in. We'd also set it so that the AuthID field was read only and pull in their ID. This would allow us to have students make forms and only need to include that field, and not have to do any other coding to make it grab the ID. If the form doesn't include that field, then it wouldn't require anyone to sign in.
Is something like this possible?
