不同

我目前正在为我的网站开发一个注册/登录系统的解决方案，我想要做的是，表'member'的每个用户在数据库中都有一个'favorites'字段，它会选择元素它希望通过addfav.php文件放入收藏夹，该文件在用户的字段“收藏夹”中添加，即在网站上选择的元素的ID。当您单击“添加到收藏夹”时，它会执行addfav.php（该文件通过URL检索元素的ID）：

    <?php 
session_start();
$_SESSION['user'] = $user_name;
if (!isset($_SESSION['login'])) {
  header ('Location: login.php');

}
$servername = "";
$username = "";
$password = "";
$dbname = "";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
$id = $_GET['id'];

if (empty($id)) {
    echo "Erreur";
}
else {

       // sql to delete a record
   $sql = "UPDATE 'members' SET 'favorite' = ".$id." WHERE 'user' = ".$user_name.""; 

   if ($conn->query($sql) === TRUE) {
    header('Location: allmovie.php');
   } else {
    echo "Error deleting record: " . $conn->error;
   }

$conn->close();


        }
?>

但它不起作用......

根据会话插入数据
