Validate Form with PHP AND JavaScript?

Question

Is it possible to validate a form with PHP and JavaScript? I\'m currently able to do both using my existing form, but only on

Answer 1

I don´t really see what the problem is, if your onsubmit action returns false in case of a non (javascript) validated form, the form simply doesn´t get submitted if javascript is enabled.

As soon as the form gets submitted, the php can do whatever it wants, validate, return errors, etc.
