That is because the form is getting submitted... make sure you js code
prevents form submit if errors are found....

Does the js function return false on the errors to block the submission?

The javascript function formValidator() must return false if any
errors are formed.

You should definitely have a better validation than that. Remember
that all users dont have javascript enabled. Moreover it is very easy
to modify the request variables.

then all the previous values are lost -- UNLESS -- you keep them in a cooki=

This is true when the page is refreshed but I doubt that is the case
here. Since $_SERVER['PHP_SELF'] is being used I think value=3D"
echo $_POST[...] ?>" will be sufficient

If you are using a post method using $_SERVER['PHP_SELF'], then values are
present in the POST array, hence, you would write your html with
interspersed php like so:
I sometimes use a function for the echoing of these values if I use the same
form for first time (ie. registration) and editing (update), and the
function checks for a $_POST value, then secondly for an existing database
value variable (ie. $row['username']). If either exist, populate the input
with it (precedence given to POST), otherwise it is empty.
The function looks something this:
function echoValue($post=null, $row=null) {
if (isset($post)) {
echo $post;
} elseif (isset($row)) {
echo $row;
}
}
and is used like this:
after performing a query on a query-string variable (eg. profile.php?id=57
---> 'SELECT * FROM `users` WHERE `id` = '.$_GET['id'] ) etc.

No, I wouldn't do it that way.
First, a "post method using $_SERVER['PHP_SELF']" is the same as
action="". A form by default, defaults to itself and thus no need for
$_SERVER['PHP_SELF'].
Second, I seldom use any POST variable without sanitizing it first.
As such, my statements always look like --
-- where the variable $user_name has been"sanitized" in some fashion
(i.e., trim, limit length, etc.).
I think that is easier to read and debug. Also, if I am using a
javascript routine (as mentioned in the OP), then I add '
id="user_name" '

I forgot to mention that $_POST does hold on to the values as well --
so, one could use that. However, you still have to repopulate the
form and that was what I was getting at.
