<?php

$paypal_id = 'my-sellerID_biz@yahoo.com'; $cancel_url = 'http://my-website/index.php?action=cancel';
$return_url = 'http://my-website/store.php';
$i = 0;
$products = array();
$qry = mysql_query("select * from temp_cart where tokenId='$token'");
while ($row = mysql_fetch_array($qry)) {
$pid = $row[0];
$pname = $row[1];
$qty = $row[3];
$price = $row[4];
$amount = $row[5];
$products[] = array('pid' => $pid, 'pname' => $pname, 'qty' => $qty, 'price' => $price, 'amount' => $amount);

这工作正常。 但付款后，当我从贝宝重定向时，我得到了失败响应。但在我的发送箱帐户中，它显示我完成。并显示我购物车。我从贝宝获取响应的代码是：-

一切正常，但我收到失败响应。 如果我忘记了什么，请帮助我。
提前致谢
