链接到此表单的PHP未将条目提交到我的数据库

<?php
// 数据库连接配置
$hostname = "localhost";
$username = "your_username";
$password = "your_password";
$database = "your_database";

// 建立数据库连接
$conn = new mysqli($hostname, $username, $password, $database);
if ($conn->connect_error) {
    die("数据库连接失败: " . $conn->connect_error);
}

// 处理表单提交
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // 获取表单数据
    $name = $_POST["name"];
    $email = $_POST["email"];
    // 其他表单字段...

    // 执行数据插入操作
    $stmt = $conn->prepare("INSERT INTO your_table (name, email) VALUES (?, ?)");
    $stmt->bind_param("ss", $name, $email);
    $stmt->execute();

    // 检查插入结果
    if ($stmt->affected_rows > 0) {
        echo "数据插入成功！";
    } else {
        echo "数据插入失败！";
