如何将html表中的行内容传递给Mysql表？

<?php
// 获取前端提交的表单数据
$field1 = $_POST['field1'];
$field2 = $_POST['field2'];
// ...

// 连接到MySQL数据库
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 将表单数据插入到MySQL表中
$sql = "INSERT INTO table_name (field1, field2) VALUES ('$field1', '$field2')";
if ($conn->query($sql) === TRUE) {
    echo "数据插入成功";
} else {
    echo "数据插入失败: " . $conn->error;
}

// 关闭数据库连接
$conn->close();
?>
