これが私のphpフォームです...同じページでそれ自体を検証できますが、データを別のphpページに渡すことができませんでした...これが私の別のphpコードです...
<?php
$forenameErr = $surnameErr = $emailErr = $postalAddressErr = $landLineTelNoErr =$mobileTelNoErr = $sendMethodErr = "";
$forename = $surname = $email = $postalAddress = $landLineTelNo = $mobileTelNo = $sendMethod = "";
echo "<h1>Successfull submission :</h1>";
echo "<p>Forename : $forename <p/>";
echo "<p>Surname : $surname <p/>";
echo "<p>Email: $email</p>";
echo "<p>Post Address: $postalAddress</p>";
echo "<p>Landline: $landLineTelNo</p>";
echo "<p>Mobile : $mobileTelNo</p>";
echo "<p>Contact method: $sendMethod";
?>
$ _SESSION変数を使用できます。
したがって、ユーザーが検証された後、 $_SESSION['surname'] = $surname;
次に、各ページの上部に追加session_start();します。
次に、その下に追加します
if (isset($_SESSION['surname'])) {
$surname = $_SESSION['surname'];
} else {
die();
}
より完全な理解については、PHPのドキュメントを参照してください。
ユーザーがアカウントを作成できるようにする場合は、MYSQLデータベースの設定を検討することもできます。
編集：フォームページ
if($valid){
$_SESSION['surname'] = $surname;
$_SESSION['postalAddress'] = $postalAddress;
header('Location: userdetail.php');
exit();
}
