Prefill linked record in form by record ID

Thank you! I was able to recreate your method!

I realized my use case is different, hence why it wasn’t originally working.
I have a bookings table from which someone can select a room or multiple room.
After they’ve selected rooms, I want to redirect them to a form with the unique codes to access the room prefilled.
I don’t want to provide the access codes prior to completing the booking because they could select rooms/access codes without hitting submit to complete the reservation.

I’m going to tinker some more to see what I’m trying to accomplish is possible.

Thanks again! Very much appreciated.

Hello there @Martin_Kopischke, Nice work on the record ID URL prefill, however, i had a question, what if it was not the record_id and if it was another field from the table? Would you just put that field name ?

Thanks
Anto
