PHP 实现报名功能

要使用 PHP 实现报名功能，需要结合 HTML 表单、PHP 后端处理和数据存储。以下是一个完整的实现方案：

创建 HTML 表单

<form action="register.php" method="post">
    <label for="name">姓名:</label>
    <input type="text" id="name" name="name" required>

    <label for="email">邮箱:</label>
    <input type="email" id="email" name="email" required>

    <label for="phone">电话:</label>
    <input type="tel" id="phone" name="phone" required>

    <label for="course">选择课程:</label>
    <select id="course" name="course">
        <option value="web">网页开发</option>
        <option value="design">平面设计</option>
        <option value="marketing">数字营销</option>
    </select>

    <button type="submit">提交报名</button>
</form>

处理表单的 PHP 代码 (register.php)

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // 获取表单数据
    $name = $_POST['name'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $course = $_POST['course'];

    // 数据验证
    if (empty($name) || empty($email) || empty($phone)) {
        die("所有字段必须填写");
    }

    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
        die("邮箱格式不正确");
    }

    // 数据库连接
    $servername = "localhost";
    $username = "username";
    $password = "password";
    $dbname = "registration_db";

    try {
        $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        // 准备SQL并绑定参数
        $stmt = $conn->prepare("INSERT INTO registrations (name, email, phone, course, registration_date) 
        VALUES (:name, :email, :phone, :course, NOW())");

        $stmt->bindParam(':name', $name);
        $stmt->bindParam(':email', $email);
        $stmt->bindParam(':phone', $phone);
        $stmt->bindParam(':course', $course);

        $stmt->execute();

        echo "报名成功！";
    } catch(PDOException $e) {
        echo "错误: " . $e->getMessage();
    }
    $conn = null;
}
?>

创建数据库表

CREATE TABLE registrations (
    id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL,
    phone VARCHAR(20) NOT NULL,
    course VARCHAR(30) NOT NULL,
    registration_date TIMESTAMP
);
