Как сохранять данные в форме

session_start();
$_SESSION["name"] = $_POST["name"];
$_SESSION["email"] = $_POST["email"];
header("Location: ".$_SERVER["HTTP_REFERER"]);
exit;
?>
 
HTML-код формы:
 
<form name="myform" action="request.php" method="post">
<input type="text" name="name" value="<?=$_SESSION["name"]?>" />
<input type="text" name="email" value="<?=$_SESSION["email"]?>" />
<input type="password" name="password" />
</form>
