注冊后自動登錄

Question

我希望用戶在注冊后自動登錄，已經嘗試了幾個小時，但到目前為止沒有任何效果。

index.php 上創建會話的代碼：

        <?php
    session_start();
    require("inc/user.functions.php");

    $sessionkey = "";
    if(isset($_SESSION['sessionkey']))
        $sessionkey = $_SESSION['sessionkey'];

    $account = new Account($sessionkey);

user.funtions.php：（登錄、注冊等）

    <?php 
require("config.php");
require("global.functions.php");

class Account {
    public $LoggedIn = false;
    public $Username;
    public $level;
    public $uid;
    public $Avatar;
    public $admin;
    public $Email;
    public $Bio;

    public function __construct($sessionkey) {
        if($sessionkey != "" && $this->session_check($sessionkey) == true) {
            $this->LoggedIn = true;
        }
    }

    private function session_check($sessionkey) {
        global $mysql;

        $query = $mysql->query("SELECT * FROM table_users WHERE sessionkey = '$sessionkey'");
        $check = $query->num_rows;
        if($check > 0) {
            while($row = $query->fetch_assoc()) {
                $this->uid = $row['uid'];
                $this->Username = $row['username'];
                $this->level = $row['level'];
                $this->Avatar = $row['avatar'];
                $this->admin = $row['admin_access'];
                $this->Email = $row['email'];
                $this->Bio = $row['bio'];
            }
            return true;
        }

        return false;
    }
}

function login_account($username, $password) {

            $hash = $row['password'];
        }

        if(verifyPassword($password, $hash) == true) {
            UpdateSession($uid);
            return true;
        } else
            return false;

    } else
        return false;
}

function register_account($firstname, $lastname, $gender, $email, $username, $password) {
    global $mysql;

    //If email is not in correct format e.g example@example.com
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        return "Vääränlainen sähköpostiosoite!";

    return false;

使用 $inseted_id=$mysqli->insert_id 獲取插入的 id 和您之前擁有的所有其他信息。 現在創建用戶會話和標題位置更改
