車屋と車の所有者が登録して売買取引を作成できる電子商取引サイトに関するプロジェクトがあります。支払いの処理方法はすでにわかっています (買い手 = 車の所有者、売り手 = 車屋)。しかし、トランザクション情報 (paypal からサーバーへ) を取得する方法がわからないので、データベースに保存できます (トランザクション ID など)。
車の所有者のショッピングカートにある私のコードは次のとおりです。
<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($_SESSION['cid']);?>
</div>
関数は次のとおりです。
<?php
function get_sum_cart($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

$get_sum_result=mysql_query($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'];

設定ファイルは次のとおりです。
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);

}
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);
そして、これが結合しようとしているものです(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;
}
}?>
これを行う方法について教えてもらえますか？
