Jerry, you are totally correct "mutually exclusive" was a poor choice
of words, "independent" would have been better. I agree with you about
the use of both types of validation. If I have JS validation, I also
have PHP/server-side validation as well.
I guess what I was trying (and failing to point out to the OP) was that
Javascript does not even truly "pass" values directly to PHP validation
code, there is always an intervening HTTP step, even with AJAX.
PMJI, I ended up looking that up in a SMS dictionary before I noticed
your second post :) I'll have to remember it for future use, and please
feel free to jump in any time I make a misleading statement (that goes
for all the others who tried to decode my poorly worded post as well)
