For forms that insert the result into a database: the unique ID can be
pre-selected and loaded into a hidden field in the form. No extra check
is needed, in the sense that the database will only let you create one
record with that unique ID.

If someone loads the the insert form a bazillion times you could
eventually run out of numbers in the database sequence. I tend not to
worrk about that.
