Question

我已经在我的localhost上为我已经工作了一段时间的网站构建了一个管理部分，一切都在我的本地主机上工作，但是当我将它上传到实时服务器时，它就不会工作 - 而且当我说不会工作，它什么都不做！登录页面加载它应该，如果我尝试访问index.php页面而不登录，它会将我重定向到login.php，因为它应该，但当我去登录时，它只是重新加载登录页面，当我去注册时它会这样做。

我花了一整天时间经历了我能想到的每一个可能的错误，我已经加倍，然后三重检查了数据库连接，表等，php，我回应了“你好世界！”从登录页面中包含的各种文件中查看它是否正确连接到它们，并且它每次都有效...我甚至检查了服务器设置的时间，因为我在另一个论坛上的某个地方看到某人有一个类似的问题，他们将服务器更新到正确的时间，并且它有效，与会话有关...但是，似乎没有任何工作。正如我之前提到的，它在我的本地主机上运行得非常好，我之前已经在现场服务器上尝试过登录，但是从那以后我做了更多工作。

供参考，这是我的登录/注册等课程：

<?php

class USER {
private $db_user;

function __construct($db) {
    $this->db_user = $db;
}

public function register($clientID,$u_fname,$u_lname,$u_tel,$u_email,$uname,$upass,$secQuestion,$secAnswer) {

    try {

        $new_password = password_hash($upass, PASSWORD_DEFAULT);

        $stmt = $this->db_user->prepare("INSERT INTO users(client_id,user,pass,first_name,last_name,telephone,email,sec_question,sec_answer) VALUES(:client,:user, :pass, :fname, :lname, :tel, :email, :secQ, :secA)");

        $stmt->bindparam(":user", $uname);
        $stmt->bindparam(":client", $clientID);
       $stmt->bindparam(":pass", $new_password);
       $stmt->bindparam(":email", $u_email);
       $stmt->bindparam(":fname", $u_fname);
       $stmt->bindparam(":lname", $u_lname);
       $stmt->bindparam(":tel", $u_tel);
       $stmt->bindparam(":secQ", $secQuestion);
       $stmt->bindparam(":secA", $secAnswer);          
       $stmt->execute();

       return $stmt;
    } catch(PDOException $e) {
        echo $e->getMessage();
    }
}

public function login($uname, $upass) {

    try {

        $stmt = $this->db_user->prepare("SELECT * FROM users WHERE user=:user LIMIT 1");
        $stmt->execute(array(':user'=>$uname));
        $userRow=$stmt->fetch(PDO::FETCH_ASSOC);
        if($stmt->rowCount() > 0) {
            if(password_verify($upass, $userRow['pass'])) {
                $_SESSION['user_session'] = $userRow['id'];
                return true;
            } else {
                return false;
            }
        }
    } catch(PDOException $e) {
        echo $e->getMessage();
    }
}

public function is_loggedin() {
    if(isset($_SESSION['user_session'])) {
        return true;
    }
}

public function logout() {
    session_destroy();
    unset($_SESSION['user_session']);
    return true;
}
}
?>

我的配置文件：

<?php 

require('constants.php');

try {
$db = new PDO("mysql:host=" . DB_SERVER . ";dbname=" . DB_NAME, DB_USER, DB_PASS);
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION);
$db->exec("SET NAMES 'utf8'");
} catch (PDOException $e) {
echo "Could not connect to the database because: " . $e->getMessage();
exit;
}

include_once 'class.user.php';
$user = new USER($db);
?>

和我的登录页面本身：

<?php
session_start();
$page_title = "Love Deals Login";
require('../inc/connect/config.php');


if($user->is_loggedin()!="") {
header("Location: index.php");
}

if(isset($_POST['login'])) {
$uname = $_POST['txt_uname'];
$upass = $_POST['txt_upass'];

if($user->login($uname,$upass)) {
    header("Location: index.php");
} else {
    $error = "Login failed. Please try again, or register";
}
}

include('inc/admin-header.php');

?>

任何可能妨碍我的脚本运行的想法？或者甚至只是指出我正确的方向，非常感谢！

尝试！empty（）而不是isset（）。
