Any pointers? ideas? suggestions?
Yes, use javascript and inform the user in real-time and before they
send the junk to the server. Of course, you then have to scrub and
clean everything, but you would have to anyway.
That works OK for something like a date or making sure that a
mandatory entry exists, but for example for a user name that has to be
unique you need to check it against your tables. Can't do that with
ECMAScript.
It helps to picture it this way:
1. Javascript is for user convenience, avoid submitting mismatched
passwords, malformed dates and so forth.
2. Server checks are about integrity, unique, referential and other
constraints
