因此，我有一个表格，我需要编辑，以便它可以提交多行，目前我有一个工作的php提交到sql中的数据（见下面的代码），但我现在添加了一个js脚本，重复另一个'代理'的输入字段行唯一的问题是当提交的形式只提交最后一个'代理'输入。
我知道这与php有关，而不是html，如果有2个“代理”或200个“代理”，我需要做什么更改才能让它提交所有字段/行。
谢谢您。
（ps im通过另一个.php连接到数据库，在服务器上，与sql的连接很好）。
PHP：

# DEBUG

# ini_set('display_startup_errors', 1);

# ini_set('display_errors', 1);

# error_reporting(E_ALL);

if (!isset($_POST['post_agent_name'])) header('Location: /');

// get database class
require_once('database.php');
$db = DataBase::SharedInstance();

// get fields
$name = $_POST['post_agent_name'];
$email = $_POST['post_agent_email'];
$location = $_POST['post_agent_location'];
$tel = $_POST['post_agent_telephone'];
$brand = $_POST['post_agent_brand'];

// do database request
$query = "INSERT INTO agents (agent_name, agent_email, agent_location, agent_telephone, agent_brand) VALUES ('%s', '%s', '%s', '%s', '%s');";
$db_result = $db->dbQuery($query, $name, $email, $location, $tel, $brand);

// handle response
if ($db_result['affected_rows']) {
    echo "<script type='text/javascript'>window.location.href = 'http://whostheagent.com/thank-you.html';</script>";
    // or header('Location: /thank-you.html');
} else {
    echo "Failed to add Agent! Please contact support";
}
