Hello

Looking for a simple script example for PHP validation on form with AJAX.

Yes, I've google this many times over and there are a lot of different
AJAX frameworks to work with.

Simple form where values/input is validated by a PHP script.

Thanks greatly

Never depend on client-side anything for validation.

You can use javascript to validate client-side, but when the user
submits the data, you *must* validate it server-side to be safe.

AJAX has nothing to do with the latter. It's just standard PHP
validation techniques.

You could use AJAX to display interactive messages and validate some of the
data, but like Jerry mentioned, it is unreliable. Use your PHP to validate the
information at the server whether or not you use AJAX to manage the data on the
client side.

That's extactly what I am wanting to do.

Use Javascript/AJAX to display the error messages for user
and use PHP (server side) to do the validation (regex, check db, etc).

Purpose of looking at AJAX is because this is all done in 'real time'
(asonychronous)

Anyone with any simple examples?

And what happens when people have javascript disabled?

Javascript should be used to *enhance* the experience, not be *required*
by the experience.

JS is optional and not always available. Do you want such a critical
thing like error messages just be an "optional feature"?

Why not start simple with the most typical and most reliable way of
validating the form data on the server and displaying the form it again
with inline error messages if something was wrong?

_After_ that is working properly, you _could_ add some client-side stuff
to pre-validate fields before the form is submitted. This doesn't have
to be done with "AJAX" - plain JS is enough in many cases.
