Contact form blank after forwarding - php

Question

I have a problem with my contact form. When the data is sent, I would like to have the fields blank again. I've tried a lot but nothing works.
Here is the script to send the mail:
<?php
error_reporting(0);
session_start();
if ("post" === strtolower($_SERVER['REQUEST_METHOD'])) {
$name = $_POST['name'];
$email = $_POST['email'];
$adres = $_POST['adres'];
$postcode = $_POST['postcode'];
$woonplaats = $_POST['woonplaats'];
$telefoon = $_POST['telefoon'];
$dag = $_POST['dag'];
$dag_nummer = $_POST['dag_nummer'];
$maand = $_POST['maand'];
$tijd = $_POST['tijd'];
$opmerking = $_POST['opmerking'];
$_SESSION['name'] = $name;
$_SESSION['email'] = $email;
$_SESSION['adres'] = $adres;
$_SESSION['postcode'] = $postcode;
$_SESSION['woonplaats'] = $woonplaats;
$_SESSION['telefoon'] = $telefoon;
$_SESSION['dag'] = $dag;
$_SESSION['dag_nummer'] = $dag_nummer;
$_SESSION['maand'] = $maand;
$_SESSION['tijd'] = $tijd;
$_SESSION['opmerking'] = $opmerking;
if (empty($name) || empty($email) || empty($telefoon) || empty($tijd)) {
if (empty($name)) {
$errors[] = "name";
}
if (empty($email)) {
$errors[] = "email";
}
if (empty($telefoon)) {
$errors[] = "telefoon";
}
if (empty($tijd)) {
$errors[] = "tijd";
}
header("Location: afspraak.php?error[]=" .implode('&error[]=', $errors));
exit;
} else {
// send mail if (post) parameters are correct
mail(
'tim-luijten#hotmail.com',
'Afsprakenformulier o-vita.nl',
"Er is contact opgenomen via het afsprakenformulier. Zie onderstaande gegevens: \n\n

exit;

}

?>

Answer 1

Since your using sessions to set the value in the inputs of the form you could just set those session values to nothing after the send occurs.
} else {
// send mail if (post) parameters are correct
if (mail(
'tim-luijten#hotmail.com',
'Afsprakenformulier o-vita.nl',
"Er is contact opgenomen via het afsprakenformulier. Zie onderstaande gegevens: \n\n
Naam: {$name} \n

Postcode: {$postcode} \n

Telefoonnummer: {$telefoon} \n
Datum: {$dag} - {$dag_nummer} - {$maand} \n
Tijd: {$tijd} \n
Opmerking: {$opmerking} \n"
,
"From: {$email} \r\n"
))
{
$_SESSION['name'] = "";
$_SESSION['email'] = "";
$_SESSION['adres'] = "";
$_SESSION['postcode'] = "";
$_SESSION['woonplaats'] = "";
$_SESSION['telefoon'] = "";
