我有关于电子商务网站的项目，车库和车主可以注册并创建买卖交易。我已经知道如何处理付款（买方=车主，卖方=车间）。但我不知道如何获取交易信息（从paypal到我的服务器），所以我可以将它保存到我的数据库。（例如，交易ID）。
这是我在车主购物车上的代码：
<div id="confrm-body">
<label> Summary of Service Requests:</label><br/>
<label>Services in your cart has been categorized by the shops the offer them. Please pay each service request respectively.</label>
<br/><label>Check out:0/3</label> <br/>
<?php get_sum_cart($_SESSION['cid']);?>
</div>
以下是功能：
<?php
function get_sum_cart($cid){
$q_get_sum_cart="select distinct(tbl_cart.shop_id),shop_name from tbl_services,tbl_carshop,tbl_cart where tbl_cart.svc_id=tbl_services.svc_id
and tbl_cart.shop_id=tbl_carshop.shop_id and tbl_cart.client_id='". $cid ."'";
$get_sum_result=mysql_query($q_get_sum_cart);
while($sum_row=mysql_fetch_array($get_sum_result)){
$shop_id=$sum_row['shop_id'];
$shop_name=$sum_row['shop_name'];
?>
<form action=<?php echo cart_url;?> method="post" >
<table class="tbl_summary">

return $t;
}
function get_discount($sub_total){
$disc=0;
$total=number_format($sub_total - ($sub_total * $disc),2);

这是配置文件：
function get_carshop_paypal($shop_id){
$get_p_add= "select pay_pal from tbl_carshop_paypal where shop_id='".$shop_id."'";
$result=mysql_query($get_p_add);
while($row=mysql_fetch_array($result)){
$shop_paypal=$row['pay_pal'];
}
return $shop_paypal;
}
define('base_url','http://'.$_SERVER['HTTP_HOST'].'/');
define('cart_currency','PHP');
define('cart_country','PH');
define('cart_url','https://www.sandbox.paypal.com/us/cgi-bin/webscr');
define('return_url',base_url.'/occs/accounts/client/index.php?p=con-transact&make='.$make.'&year='.$year.'&model='.$model);
这是我想要结合的东西（IPN_handler）：
class Paypal_IPN
{
private $_url;
public function __construct($mode = 'live')
{
if ($mode == 'live')
$this->_url = 'https://www.paypal.com/cgi-bin/webscr';
else
$this->_url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
}
public function run()
{
$postFields = 'cmd=_notify-validate';
foreach($_POST as $key => $value)
{
$postFields .= "&$key=".urlencode($value);
}
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $this->_url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => $postFields
));
$result = curl_exec($ch);
curl_close($ch);
$fh = fopen('result.txt', 'w');
fwrite($fh, $result . ' -- ' . $postFields);
fclose($fh);
echo $postFields;
}
}?>
你们能告诉我如何做到这一点吗？
答案 0 :(得分：0)
您需要做的就是自定义该IPN库以包含您自己的数据库插入，然后确保在您的PayPal帐户配置文件中启用了IPN。您还可以在按钮代码中使用notify_url来覆盖配置文件设置，但我喜欢将我的配置文件设置为默认的IPN侦听器。
您可能对我的PHP template for PayPal IPN感兴趣。它非常受欢迎，虽然它可以重新开发为面向对象的类（我打算这样做），它可以很好地工作，并为您提供一个可以在您的数据库中记录所有IPN的工作IPN解决方案。
我几乎用于所有项目。只需安装IPN模板（下载中包含的说明），然后您就可以使用记录ID将IPN数据与您自己的数据相关联。例如，我总是在我的PayPal请求中包含invoice参数，以便将我的本地记录ID传递给PayPal。这样它也会在IPN中作为发票参数返回。我只是将它用作现有表的关系，用于我正在工作的任何项目，并且所有IPN数据都可用于该记录而无需进一步定制。
你可以在大约10分钟内完成它。
