未定義的索引：$ _SESSION []

我已經將我的網站從本地移動到liv服務器上的子域，並且在我的登錄腳本週圍出現了一些問題，它在本地完美工作，但似乎會話不起作用我預計自移動在線。

所以我的腳本如下所示：

<?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(); 

?>

所以非常簡單的沒有章法，但是當我通過數值要乒我回一些錯誤：

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_2_status in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 21 

Notice: Undefined index: video_3_status in /var/sites/r/reedvid.mydomain.co.uk/public_html/actions/login-action.php on line 22 

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

很清楚什麼告訴我，但我不完全確定A：爲什麼這在本地工作和B：什麼是錯的？

您沒有在查詢中選擇video_statuses，您只選擇了user_email，並且僅輸入了密碼 –

確保在您的php.ini中的Web服務器上，您的會話保存正確。您也可以嘗試查看它是否每次刷新時都生成新會話session_id();
