Register a token in a session var after submitting the
form. When the user get's again on the resubmitted page
you should test if the token exists in the session. If
it does, you know he has resubmitted the form.
<?php
if (isset($_POST["submit"])) {
if (!isset($_SESSION["token"])) {
$_SESSION["token"] = "submitted";
/**
* continue validating, parsing etc.
* the data
*/
} else {
/**
* error: form was resubmitted
*/
}
} else {
/**
* display form
*/
?>
<form action="<?php print $PHP_SELF; ?>" method="POST">
.
.
.
</form>
<?php
}
.
.
.
?>
