我的問題是，用戶登錄成功後。我能得到他的電子郵件ID，但是當我嘗試插入到另一個表中的錯誤表示當Iam未獲取登錄用戶的電子郵件插入數據庫
「未定義USEREMAIL」 這是我第booking.php
<?php
session_start();
echo $_SESSION['userEmail'];
?>
<?php
session_start();
require_once 'class.user.php';
$user_home = new USER();
if (!$user_home->is_logged_in())
{
$user_home->redirect('login.php');
}
$stmt = $user_home->runQuery("SELECT * FROM tbl_users WHERE userID=:uid");
$stmt->execute(array(":uid" => $_SESSION['userSession']));
$row = $stmt->fetch(PDO::FETCH_ASSOC);
?>
<?php
if (isset($_POST['submit'])):
$email = $_SESSION['userEmail'];
$seva = $_POST['seva_name'];
$date = $_POST['booking_date'];
$persons_no = $_POST['persons'];
@mysql_connect("localhost", "root", "") or die("Connection error");
@mysql_select_db("bhavya") or die("Database Selection error");
$query = @mysql_query("select * from booking where userEmail='" . $userEmail . "'") or die("selection error");
if (mysql_num_rows($query) <= 150):
$sql = "insert into booking (userEmail, seva_name, booking_date, persons) values ('$email', '$seva', '$date', '$persons_no')" or die("insertion error");
$result = mysql_query($sql);
if ($result):
function send_mail($message, $subject)
{
require_once('mailer/PHPMailerAutoload.php');
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = true;
$mail->SMTPSecure = "ssl";
$mail->Host = "smtp.gmail.com";
$mail->Port = 465;
$mail->AddAddress($email);
$mail->Username = "ya[email protected]";
$mail->Password = "xxxxxx";
$mail->SetFrom('[email protected]', 'Krthik');
$mail->AddReplyTo("[email protected]", "Karthik");
$mail->Subject = $subject;
$mail->MsgHTML($message);
$mail->Send();
header("Location: index.php");
}
endif;
endif;
endif;
?>

我'得到的錯誤是 
這是我的登錄頁面（login.php中）
<?php

require_once 'class.user.php';
$user_login = new USER();
if($user_login->is_logged_in()!="")
{
$user_login->redirect('index.php');

if($user_login->login($email,$upass))

$user_login->redirect('index.php');
}
