我的联系表格有问题。发送数据时，我希望再次将这些字段留空。我已经尝试了很多，但没有任何作用。
以下是发送邮件的脚本：
<?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

由于您使用会话来设置表单输入中的值，因此您可以在发送后将这些会话值设置为空。
