I have a form where people can send a unique code found in a product they buy. They have to submit this code with this form, this code is a unique code (5 figures) which can be only send once.
Is there a way to check if the code already has been submitted?

(I hope my English is good enough to understand the question)

Thanx

Yes, afaik the only way would be through the use of UDT's. But you would need, at the very least some solid knowledge of PHP, and of Form Builder, as it is not a basic task.

I would use ListIt2 - to store the already used codes - and ListIt2FEEdit to create the form and check is the code has already been used.
