Note Submitter: coda at bobandgeorge dot com ---- alwaysdrunk's comment only works if you can trust the client web browser. Using this function doesn't validate that every necessary field exists -- only that every field that was submitted has a value in it. Thus if an attacker wished to force a null value into one of the fields, he could (rather easily) construct a modified form without the field and submit THAT. Besides, you really ought to be validating each field anyway if you're taking user input.
