Registration Form - Supply responses via URL
I have a Zoom registration form for an event, which asks for First Name, Last Name and Email Address. I am directing classmates to this form from our class website. I want to not require them to complete the above 3 fields as that information is known to us on the sending website before the redirect. How do I supply this information in the redirect (either in the URL or in a POST format)? And how do I find out the names of these three fields? I am using PHP on my server side and HTML/JavaScript on the client side.
