: From: "Czechowski, Aaron" <aczechowski at towson.edu>
: so you suggest/recommend doing BOTH types of validation?

yes.  server-side as a standard and client-side everywhere that's possible.

: client-side for ease of use, and server-side just-in-case?  but if
: your client-side is thorough, you shouldn't need to waste time on
: server-side validation, right?

client-side to ease the load on the server.  server-side to guarantee the
accuracy of the data going into the database.

: or is your thinking that for older browsers that might not be able
: to handle all of the fancy javascript validation?

no, you can never be guaranteed that the data coming from the browser is
accurate and correct, even if your form has client-side validation.  you
can't even be guaranteed that it's coming from your form.  so, to stop
someone from downloading your form page to their system, hacking out your
client-side validation and submitting bogus data you validate server-side as

good luck,
