Validation is always performed server side.
if you use FORM(....INPUT(....)....) that each input gets its own
requires=[..]
if you use SQLFORM(table) than the requires are from the
table.field.requires.
Anyway, do not use FORM(...INPUT(....)...) but use
SQLFORM.factory(...Field(...)...) It is more powerful.
