php - 如何根据用户的状态和角色登录用户

<分区>

我正在创建一个登录页面，用户和管理员将在其中登录用户将具有角色 = 用户和状态 = 待定，直到管理员将其激活。我有不同的文件要显示给用户和管理员，在用户内部，有 2 个文件。 1 个用于活跃用户，另一个用于待定用户。

我创建了 if 语句并尝试了 switch 语句。但我在 XAMPP 上收到错误消息“解析错误:语法错误，C:\xampp\htdocs\MakerLab\server.php 中第 109 行的文件意外结束”

这是我的 server.php

最佳答案

文件末尾缺少 2 个括号(在 ?> 标记之前)下次您可以使用像 PHPStorm 这样的 IDE 来帮助缩进和格式化。

<?php

// variable declaration
$email = "";
$status = "";

$errors = array();
$_SESSION['success'] = "";

// connect to database
$db = mysqli_connect('localhost', 'root', '', 'makerlab');

// REGISTER USER
if (isset($_POST['reg_user'])) {
    // receive all input values from the form
    $fname = mysqli_real_escape_string($db, $_POST['fname']);
    $lname = mysqli_real_escape_string($db, $_POST['lname']);
    $email = mysqli_real_escape_string($db, $_POST['email']);
    $lewisID = mysqli_real_escape_string($db, $_POST['lewisID']);
    $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);
    $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);

    // form validation: ensure that the form is correctly filled
    //if (empty($email)) { array_push($errors, "Lewis Email is required"); }
    //if (empty($password_1)) { array_push($errors, "Password is required"); }

    //if ($password_1 != $password_2) {

    //}

    $user_check_query = "SELECT * FROM users WHERE lewisID='$lewisID' OR email='$email' LIMIT 1";
