Is javascript the way to go??????????

All PHP can do is output some kind of data: HTML, HTML w/ Javascript, other content types, etc. It's not a GUI language.

If you want to have a message box, make the PHP output some HTML w/ javascript code to print out the message box.

what kind of message box do you have in mind? textarea? javascript alert?

An alert if the input to a text area has invalid characters.Realised that I goofed up PHP is server side scripting right.

if(!is_a_valid_field($my_field)) {
?>
<SCRIPT LANGUAGE="JavaScript">
<!--
alert("<my_field> is invalid");
// -->
</SCRIPT>
<?
}
