Good Day,
                I need help in in validating a form.
                The for is valdated be a javascript frist then if all the fields are filled in its valaded be PHP.
                The Form starts with:
                <form name="myForm" action="<?php echo $_SERVER['PHP_SELF'];?>" method="post" onsubmit='return formValidator()' >
The "formValidator()" goes to a javascript and does display the missing information in this case BUT then the page gets reloaded and clears all the javascript error messages and does the PHP validation. The PHP only runs if the fields are set by testing using 'isset". Without puting on numeric lines of go can you suggest things I must have overlooked. Silly request but there must be something I'm
overlooking.    I have simular code on other programs but this one is casuing me trouble.
Thanks every so much..
Ernie: Client-side javascript can help populate fields and correct any problems a user might have, but once the form is submitted to the server, then the data is sent and evaluated server-side, hence validation. However, if the server-side evaluation fails and the page is refreshed, then all the previous values are lost -- UNLESS -- you keep them in a cookie, database, or session. I suggest using a session.
