初学者问题: 要管理他的个人资料，注册成员(member)必须能够通过 Plupload 插件上传/修改头像。
仅在 upload.php 文件中，要更新数据库(“users”表)，我需要 $_SESSION['auth'] 变量给出的用户 ID。
此变量存在于 profile.php 中:var_dump($_SESSION['auth']) 给出:
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 'john@doe.com' (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)
但是我无法将$_SESSION['auth']传输到upload.php。请告诉我如何做。
配置文件.php:
if(session_status() == PHP_SESSION_NONE){ session_start(); }
require_once('inc/functions.php');
require_once('inc/db.php');
reconnect_from_cookie();

最佳答案
您必须使用session_start() 来恢复 session 。只需删除前面的 if 即可每次启动。 Documentation
替换
if(session_status() == PHP_SESSION_NONE){ session_start(); }
由
session_start();
