Creating a demo for a member management system with PHP and an MVC framework requires several steps, including setting up a database, defining the model, creating views, and implementing controller actions. Below is a simplified example using PHP and MySQL for the database. Please note that this is a basic demonstration, and in a production environment, you would need to enhance security, validation, error handling, and other aspects. **Prerequisites:** 1. PHP installed on your machine. 2. A web server (e.g., Apache) set up to run PHP scripts. 3. MySQL database installed and running. Here's a step-by-step guide: 1. **Database Setup:** Create a MySQL database named `toucantech` and a table named `members` to store member information. You can use a tool like phpMyAdmin or run SQL commands from the terminal. ```sql CREATE DATABASE toucantech; USE toucantech; CREATE TABLE members ( id INT AUTO_INCREMENT PRIMARY KEY, name VARCHAR(255) NOT NULL, email VARCHAR(255) NOT NULL, school VARCHAR(255) NOT NULL ); ``` 2. **MVC Directory Structure:** Organize your project files into an MVC directory structure. For example: ``` - /public - index.php - /app - /controllers - MemberController.php - /models - MemberModel.php - /views - add_member.php - show_members.php ``` 3. **Create Model (MemberModel.php):** Define a PHP class to interact with the database. ```php <?php class MemberModel { private $conn; public function __construct($db) { $this->conn = $db; } public function addMember($name, $email, $school) { $query = "INSERT INTO members (name, email, school) VALUES (?, ?, ?)"; $stmt = $this->conn->prepare($query); $stmt->bind_param("sss", $name, $email, $school); return $stmt->execute(); } public function getMembersBySchool($school) { $query = "SELECT * FROM members WHERE school = ?"; $stmt = $this->conn->prepare($query); $stmt->bind_param("s", $school); $stmt->execute(); $result = $stmt->get_result(); return $result->fetch_all(MYSQLI_ASSOC); } } ``` 4. **Create Controller (MemberController.php):** Define a controller to handle HTTP requests and render views. ```php <?php require_once('../models/MemberModel.php'); class MemberController { private $model; public function __construct($db) { $this->model = new MemberModel($db); } public function addMember() { if ($_SERVER['REQUEST_METHOD'] === 'POST') { $name = $_POST['name']; $email = $_POST['email']; $school = $_POST['school']; if ($this->model->addMember($name, $email, $school)) { header("Location: show_members.php?school=$school"); exit; } } include('../views/add_member.php'); } public function showMembers($school) { $members = $this->model->getMembersBySchool($school); include('../views/show_members.php'); } } ``` 5. **Create Views (add_member.php and show_members.php):** Create HTML forms for adding members and displaying members by school. - `add_member.php` for adding a new member. - `show_members.php` for displaying members by school. 6. **Create the Entry Point (index.php):** This file will route requests to the appropriate controller action. ```php <?php require_once('../app/controllers/MemberController.php'); $db = new mysqli("localhost", "root", "", "toucantech"); // Adjust the database credentials if (!$db) { die("Database connection failed: " . $db->connect_error); } $controller = new MemberController($db); if (isset($_GET['action'])) { $action = $_GET['action']; if (method_exists($controller, $action)) { $controller->$action(); } else { echo "Invalid action."; } } else { echo "Invalid request."; } ``` 7. **Testing:** Start your web server and access the application through `http://localhost/path/to/index.php?action=addMember` to add members or `http://localhost/path/to/index.php?action=showMembers&school=YourSchool` to view members for a specific school. Remember to implement proper error handling, input validation, authentication, and security measures when deploying this in a real-world scenario. This is a basic example to get you started with a PHP MVC-based member management system.
