I always capture the values into a session and when the form is created
I echo the session values into the value="" section, or whatever is
needed, different in the case of checkboxes etc., have to mark as
selected="selected" etc.
You could use normal cookies too if you don't want to start a server
session.

I usually use a header redirect back to forms when data is invalid or
when a succesful submission is made, I use a session var 'messages' to
hold any messages to print at the top of the form
eg.
$_SESSION['messages'] = 'Your submission was invalid';
exit(header("Location: {$_SERVER['PHP_SELF'}"));
