Hi Michael,
on the processing page after the form array is verified and email
address is validated,
the code goes like this:
if ($_POST) {
// save post into a cookie to retrieve later - careful with
captcha fields, do not restore those in interface
setcookie("form", serialize($_POST), time()+300);
if (captcha::check()) {
if (verify_form($required, $_POST)) {
//follow the same structure as verify form. So now, if the form is
verified, we continue. Otherwise we will error out with redirect
if ( (validate_email($email)) ) {
// redirect to this url on full success and email form
header('Location:
http://www.wll.com/thankyou.shtml');
$_POST['RemoteIP'] = $_SERVER['REMOTE_ADDR'];
mail_form(SENDER, RECIPIENT, SUBJECT, $_POST);
} else {
// If not validate email;
header('Location: ' . $_SERVER['HTTP_REFERER']);
}
} else {
// If verify form failed
header('Location: ' . $_SERVER['HTTP_REFERER']);
}
exit;
} else {
// if not capture
$_SESSION["error"] = 'Verification word does not match';
header('Location: ' . $_SERVER['HTTP_REFERER']);
}
exit;
} else {
// if no $_POST variable
if ($HTTP_COOKIE_VARS['form']) {
//$form array can be used to set form field values
// this server sucks, need to remove added slashes
$form = unserialize(stripslashes($HTTP_COOKIE_VARS['form']));
// destroy cookie on client side
setcookie('form', '');
}
// echo $captcha puts captcha anywhere in the interface
$captcha = captcha::form("→ ");
}
Back on the page containing the form, a block of code linking session
"error" to the data array
if ($_SESSION["error"]) {
echo '<font color="red">' . $_SESSION["error"] . '</font>';
unset($_SESSION["error"]);
}
and reference to the required form data is tucked away:
<form action="quote.php" method="POST">
<input type="hidden" name="print_blank_fields" value="1">
<!--<input type=hidden name="sort" value="order:Contact
Name,Company,Street,City,State,Zip Code,email,Phone,Fax,EMC Compliance
Testing,Product Safety,Educational Seminars,Site
Surveys,Telecom,Wireless Approvals,Consulting and EMC Specialties, PCS
Site Surveys,Other,Comments">-->

So i understand that session error shows which required field was not
entered by the user... but, what happens to the session vars with the
form data?
