初心者質問： プロフィールを管理するには、登録メンバーがPluploadプラグインを使用してアバターをアップロード/修正できる必要があります。Plupload：データベース内のアバターアップロードを更新するためにupload.phpにセッション変数を渡す
upload.phpファイルでのみデータベース（ 'users'テーブル）を更新するには、$_SESSION['auth']という変数のユーザーIDが必要です。
この変数はprofile.phpに存在する：
C:\wamp\www\graf\profile.php:24:
object(stdClass)[1]
public 'id' => string '22' (length=2)
public 'username' => string 'johndoe' (length=6)
public 'email' => string '[email protected]' (length=17)
public 'password' => string '$2y$10$nwS.6PlyuH7NQnRuPdRJnuLmPSJK/gzmcWomHYz5Uk3SOkDutnLQ.' (length=60)
public 'confirmation_token' => null
public 'confirmed_at' => string '2016-11-29 12:27:40' (length=19)
public 'reset_token' => null
public 'reset_at' => null
public 'remember_token' => null
public 'avatar' => string 'John-Doe.png' (length=12)
しかし、私はupload.phpする$_SESSION['auth']を送信することはできません。var_dump($_SESSION['auth'])ができます。方法を教えてください。
profile.php：
if(session_status() == PHP_SESSION_NONE){ session_start(); }
require_once('inc/functions.php');
require_once('inc/db.php');
reconnect_from_cookie();
