Do you varify this in Javascript? If yes, just add the following to your form header and replace VarifyForm with your own function name. If the form is return true; in your function and if it isn't valid return false;

onSubmit="return VarifyForm();"

While you're validating you can save the submitted data in a $_SESSION variable. When you redraw the form you can populate the fields with it.
