PHP Paypal Hotel Reservation ввод из поля ввода не сохраняет только PayPal платеж

Question

PHP Paypal Hotel Reservation, введенное из поля ввода, не сохранит только платеж PayPal

Я хочу сохранить свои входные данные из кассы, но при этом будет сохранена только информация PayPal

checkout.php

<?php
// Redirect to the home page if id parameter not found in URL
if(empty($_GET['id'])){
    header("Location: reservation.php");
}

// Include and initialize database class
include 'DB.class.php';
$db = new DB;

// Include and initialize paypal class
include 'PaypalExpress.class.php';
$paypal = new PaypalExpress;

// Get product ID from URL
$productID = $_GET['id'];

// Get product details
$conditions = array(
    'where' => array('id' => $productID),
    'return_type' => 'single'
);
$productData = $db->getRows('products', $conditions);

// Redirect to the home page if product not found
if(empty($productData)){
    header("Location: index.php");
}

?>

Всякий раз, когда я проверяю, он сохраняет только информацию Paypal, а не информацию пользователя вместе с ними
