我想在PayPal付款表单中添加一个变量。然后我希望它被添加到数据库中。该变量被称为＆＃34; membre_id＆＃34; （用户ID），可在$ _SESSION [＆＃39; membre_id＆＃39;]中找到。
以下是表单处理的代码：
<?php
require 'lib/init.php';
$action = isset($_POST['action']) ? $_POST['action'] : (isset($_GET['action']) ? $_GET['action'] : '');
if ( !empty($action) ) {
switch ( $action ) {

API请求中有一个名为“custom”的参数。这就是你传递数据所需要的，然后它会在IPN中返回$ _POST ['custom']
