我试图弄清楚为什么INSERT INTO不起作用。它适用于$ _POST但它不适用于$ _SESSION。这是我的代码：
第1步 - 这是我在结账过程中第一步使用的表格：
if (!empty($_POST)) {
$sex = $_POST['sex'];
$first_name = $_POST['first_name'];
$family_name = $_POST['family_name'];
$birthday = $_POST['birthday'];
$address = $_POST['address'];
$plz = $_POST['plz'];
$city = $_POST['city'];
$land = $_POST['land'];
$email = $_POST['email'];
$password = $_POST['password'];
$password_confirmation = $_POST['password_confirmation'];
$agbs = $_POST['agbs'];
$newsletter = $_POST['newsletter'];
$shipping_address = $_POST['shipping_address'];
$shipping_plz = $_POST['shipping_plz'];
$shipping_city = $_POST['shipping_city'];
$shipping_land = $_POST['shipping_land'];
$is_admin = $_POST['is_admin'];
$created_at = time();
// Validieren
if (!empty($email) && !empty($family_name) && !empty($password) && !empty($password_confirmation) && !empty($agbs)) {
if ($password == $password_confirmation) {
$password_hash = password_hash($password, PASSWORD_BCRYPT); );
$_SESSION['sex'] = $sex;
$_SESSION['first_name'] = $first_name;
$_SESSION['family_name'] = $family_name;
$_SESSION['birthday'] = $birthday;
$_SESSION['address'] = $address;
$_SESSION['plz'] = $plz;
$_SESSION['city'] = $city;
$_SESSION['land'] = $land;
$_SESSION['email'] = $email;
$_SESSION['password'] = $password;
$_SESSION['password_hash'] = $password_hash;
$_SESSION['agbs'] = $agbs;
$_SESSION['newsletter'] = $newsletter;
$_SESSION['shipping_address'] = $shipping_address;
$_SESSION['shipping_plz'] = $shipping_plz;
$_SESSION['shipping_city'] = $shipping_city;
$_SESSION['shipping_land'] = $shipping_land;
$_SESSION['is_admin'] = $is_admin;
header("location: ?site=zahlungsart_waehlen");
if($error = 1 && $mysql_error = mysqli_errno($link)) {
if ($mysql_error == 1062) {
$email_error = "Deine Email Adresse existiert bereits";
} else {
echo $mysql_error;
}
}
// wenns nicht funktioniert: Fehler + Formular ausgeben
} else {
$error = 1;
$pswrd_error = "Deine eingegebenen Passwörter stimmen nicht überein";
}
// wenns nicht funktioniert: Fehler + Formular ausgeben
} else {
$error = 1;
// felder sind leer
$fields_error = "Bitte fülle alle Felder aus";
}
}
if ($error == 1 || empty($_POST)) {
// Formular anzeigen
$includes_from_logic[] = "views/checkout.php";
}
第2步 - 在第一步之后，我可以选择也写入会话的付款选项：
if (!empty($_POST)) {
$sex = $_SESSION['sex'];
$first_name = $_SESSION['first_name'];
$family_name = $_SESSION['family_name'];
$birthday = $_SESSION['birthday'];
$address = $_SESSION['address'];
$plz = $_SESSION['plz'];
$city = $_SESSION['city'];
$land = $_SESSION['land'];
$email = $_SESSION['email'];
$password = $_SESSION['password'];
$password_hash = $_SESSION['password_hash'];
$agbs = $_SESSION['agbs'];
$newsletter = $_SESSION['newsletter'];
$shipping_address = $_SESSION['shipping_address'];
$shipping_plz = $_SESSION['shipping_plz'];
$shipping_city = $_SESSION['shipping_city'];
$shipping_land = $_SESSION['shipping_land'];
$is_admin = $_SESSION['is_admin'];
$sql = "INSERT INTO users (sex, first_name, family_name, address, plz, city, land, email, password_hash, agbs, newsletter, created_at, shipping_address, shipping_plz, shipping_city, shipping_land, birthday, is_admin) VALUES
('$sex', '$first_name', '$family_name', '$address', '$plz', '$city', '$land', '$email', '$password_hash', '$agbs', '$newsletter', '$created_at', '$shipping_address', '$shipping_plz', '$shipping_city', '$shipping_land', '$birthday', 0)";
$res = mysqli_query($link, $sql) or die($sql);
}
的var_dump（$ _ SESSION）;
array(23) { ["prozess"]=> array(6) { ["name"]=> string(3) "ddd" ["party"]=> string(10) "Regenbogen" ["birthdate"]=> string(10) "0002-02-22" ["guests"]=> string(1) "2" ["step"]=> string(6) "extras" ["partyPrice"]=> float(39.9) } ["cart"]=> array(0) { } ["is_recipient"]=> bool(true) ["sex"]=> NULL ["first_name"]=> string(7) "Beverly" ["family_name"]=> string(13) "Beverly Hills" ["birthday"]=> string(5) "Lrzfs" ["address"]=> string(15) "4782 Beverly Dr" ["plz"]=> string(4) "4782" ["city"]=> string(13) "Beverly Hills" ["land"]=> string(11) "Österreich" ["email"]=> string(26) "bhills_4782@mailinator.com" ["password"]=> string(1) "1" ["password_hash"]=> string(60) "$2y$10$M4FFQLuYJbyeIkGy7ZaOfuD0r4YVr3sL/O/JyLFe881h0BzCE8yse" ["agbs"]=> string(2) "JA" ["newsletter"]=> NULL ["shipping_address"]=> string(15) "4782 Beverly Dr" ["shipping_plz"]=> string(4) "4782" ["shipping_city"]=> string(13) "Beverly Hills" ["shipping_land"]=> string(11) "Österreich" ["is_admin"]=> NULL ["payment_method"]=> string(11) "Kreditkarte" ["bestellung_ueberpruefen"]=> NULL }
