我正在使用Paypal Standard，我试图在成功交易完成后从paypal获取item_number（在此用例中是唯一的）。我可以毫无问题地将它传递给PayPal，我看到它在交易期间显示出来。我在事务完成时使用以下代码。有人可以告诉我在成功页面上显示项目_number需要做什么 - 请参阅下面的成功案例。
<?php
require_once("library.php"); // include the library file
define('EMAIL_ADD', 'me@gmail.com'); // define any notification email
define('PAYPAL_EMAIL_ADD', 'me-facilitator@gmail.com'); // facilitator email which will receive payments change this email to a live paypal account id when the site goes live
require_once("paypal_class.php");
$p = new paypal_class(); // paypal class
$p->admin_mail = EMAIL_ADD; // set notification email
$action = $_REQUEST["action"];
switch($action){
case "process": // case process insert the form data in DB and process to the paypal

答案 0 :(得分：0)
我接到你的电话，并在我的笔记中明天打电话给你。然后我就在这里找到了这个问题。
我假设您的帐户已经启用了PDT，并且自动返回设置指向您的返回网址。
有了这个假设，你只需要调整$ _GET [＆＃39; item_number＆＃39;]。 PDT / IPN不会（通常）以这种方式发送。您知道如何在请求中将其构建为item_number_1，item_number_2等吗？当你把它拉出来时你需要做同样的事情，除了PayPal决定使事情变得有趣并删除第二个_那里。所以你要使用的是$ _GET [＆＃39; item_number1＆＃39;]，$ _GET [＆＃39; item_number2＆＃39;]等。
当然，您通常会通过某种循环来挑选订单中可能包含的所有商品。这就是我总是在我的IPN脚本中提取项目详细信息的方式（对于PDT也是如此）
// Cart Items
$num_cart_items = isset($_POST['num_cart_items']) ? $_POST['num_cart_items'] : '';
$i = 1;
$cart_items = array();
while(isset($_POST['item_number' . $i]))
{
$item_number = isset($_POST['item_number' . $i]) ? $_POST['item_number' . $i] : '';
$item_name = isset($_POST['item_name' . $i]) ? $_POST['item_name' . $i] : '';
$quantity = isset($_POST['quantity' . $i]) ? $_POST['quantity' . $i] : '';
$mc_gross = isset($_POST['mc_gross_' . $i]) ? $_POST['mc_gross_' . $i] : 0;
$mc_handling = isset($_POST['mc_handling' . $i]) ? $_POST['mc_handling' . $i] : 0;
$mc_shipping = isset($_POST['mc_shipping' . $i]) ? $_POST['mc_shipping' . $i] : 0;
$custom = isset($_POST['custom' . $i]) ? $_POST['custom' . $i] : '';
$option_name1 = isset($_POST['option_name1_' . $i]) ? $_POST['option_name1_' . $i] : '';
$option_selection1 = isset($_POST['option_selection1_' . $i]) ? $_POST['option_selection1_' . $i] : '';
$option_name2 = isset($_POST['option_name2_' . $i]) ? $_POST['option_name2_' . $i] : '';
$option_selection2 = isset($_POST['option_selection2_' . $i]) ? $_POST['option_selection2_' . $i] : '';
$option_name3 = isset($_POST['option_name3_' . $i]) ? $_POST['option_name3_' . $i] : '';
$option_selection3 = isset($_POST['option_selection3_' . $i]) ? $_POST['option_selection3_' . $i] : '';

$option_selection7 = isset($_POST['option_selection7_' . $i]) ? $_POST['option_selection7_' . $i] : '';
$option_name8 = isset($_POST['option_name8_' . $i]) ? $_POST['option_name8_' . $i] : '';
$option_selection8 = isset($_POST['option_selection8_' . $i]) ? $_POST['option_selection8_' . $i] : '';
$option_name9 = isset($_POST['option_name9_' . $i]) ? $_POST['option_name9_' . $i] : '';
$option_selection9 = isset($_POST['option_selection9_' . $i]) ? $_POST['option_selection9_' . $i] : '';
$btn_id = isset($_POST['btn_id' . $i]) ? $_POST['btn_id' . $i] : '';
$current_item = array(
'item_number' => $item_number,
'item_name' => $item_name,
'quantity' => $quantity,
'mc_gross' => $mc_gross,
'mc_handling' => $mc_handling,
'mc_shipping' => $mc_shipping,
'custom' => $custom,
'option_name1' => $option_name1,
'option_selection1' => $option_selection1,
'option_name2' => $option_name2,
'option_selection2' => $option_selection2,
'option_name3' => $option_name3,
'option_selection3' => $option_selection3,
'option_name4' => $option_name4,
'option_selection4' => $option_selection4,
'option_name5' => $option_name5,
'option_selection5' => $option_selection5,
'option_name6' => $option_name6,
'option_selection6' => $option_selection6,
'option_name7' => $option_name7,
'option_selection7' => $option_selection7,
'option_name8' => $option_name8,
'option_selection8' => $option_selection8,
'option_name9' => $option_name9,
'option_selection9' => $option_selection9,
'btn_id' => $btn_id
);
array_push($cart_items, $current_item);
$i++;
}
加载$ cart_items，包含所有不同的项目，然后您可以循环输出相应的参数。
