Question

我已经将我的网站从本地移动到了liv服务器上的子域，我在登录脚本方面遇到了一些问题，我们都在本地完成了工作，但似乎会议因为在线移动而无法正常工作。 / p>

所以我的脚本如下所示：

<?php
session_start();
include_once '../config.php';

$email = mysqli_real_escape_string($conn, $_POST['email']);
$password = mysqli_real_escape_string($conn, $_POST['password']);

$query = "SELECT user_email, user_password FROM users WHERE (user_email = '". $email ."')";
$result = $conn->query($query);

if ($result->num_rows === 1) {

    $row = $result->fetch_array(MYSQLI_ASSOC);

    if (password_verify($password, $row['user_password'])) {

        $_SESSION['user_id'] = $row[ 'user_id' ];
        $_SESSION['user_email'] = $row[ 'user_email' ];

        $_SESSION['video_1_status'] = $row[ 'video_1_status' ];
        $_SESSION['video_2_status'] = $row[ 'video_2_status' ];
        $_SESSION['video_3_status'] = $row[ 'video_3_status' ];
        $_SESSION['video_4_status'] = $row[ 'video_4_status' ];             

        header('Location: ../home.php');         

        } else{
            header('Location: ../login.php?message=Email address or password is incorrect');
        }

    } else{
    header('Location: ../login.php?message=Email address or password is incorrect');
}

$conn->close();

?>

如此简单明了没有技巧，但是当我传递这些值时，它会给我带来一些错误：

Notice: Undefined index: user_id in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 17

Notice: Undefined index: video_1_status in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 20

Notice: Undefined index: video_4_status in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 23

Warning: Cannot modify header information - headers already sent by (output started at /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php:17) in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 25

很清楚它告诉我的是什么，但我不完全确定A：为什么这在本地工作而B：出了什么问题？

确保在php.ini中的网络服务器上正确保存会话。您还可以尝试通过打印session_id();

来确定每次刷新时是否生成新会话

未定义的索引：$ _SESSION []
