Trying to figure out how to make an entry form for user which he/she can only submit once. This could go to a channel. But the idea is to only enable the user to submit that data once.
I’ll roughly describe what I need.
Imagine there is some gameplay that all users can be part of. It’s based on predicting a certain outcome. Lets say for each game a user can submit 5 numbers. There will be multiple games each day but then can only enter each one once.
I am trying to figure out a way to do this most efficiently. Any suggestion will be welcome.
