PHP-PayPal集成,在接受付款后无法运行我的自定义交易功能
我曾经尝试过使用PayPal支付的教程脚本,但效果不错。现在没有了。脚本很简单,我只需要这一页来处理付款:PHP-PayPal集成,在接受付款后无法运行我的自定义交易功能,php,paypal,Php,Paypal,我曾经尝试过使用PayPal支付的教程脚本,但效果不错。现在没有了。脚本很简单,我只需要这一页来处理付款: <?php session_start(); include ('mydbconfig.php'); // payPal settings $paypal_email = 'seller@yahoo.com'; $return_url = 'https://www.mytestsite.com/paypal-thanks.php'; $cancel_url

// append amount& currency (£) to quersytring so it cannot be edited in html

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
if (!$fp) {

//function to insert transaction here
} else if (strcmp ($res, "INVALID") == 0) {
//something to do if failed

fclose ($fp);

?>
流程完成后,我进行了检查并成功支付了款项,但我的函数或我在//函数中编写的用于在此处插入交易的任何内容都不会执行。最后,我被迫在paypal-thanks.php页面上执行该函数。剧本里有什么不对劲吗
此脚本是否可用于发送多个采购项目?我的购物车是我自己定制的,我只想将商品名称、编号、价格详细信息和总价发送到PayPal订单摘要
我在这里查看了其他PayPal集成问题,其中大多数问题都会让我联想到PayPal教程、文档或集成向导,这让我很困惑。我以前使用过这个简单的脚本,因为我不理解PayPal文档(以及示例代码,它甚至不让我知道从哪里开始):(
最后,我的终极问题是,这个脚本是进行支付交易的正确且安全的方法吗?使用这个脚本
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);
而不是
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
我认为最好使用CURL而不是socket之前我遇到过类似的问题。PayPal指南中建议的代码没有更新。尝试使用:它是一个PHP5类,用于处理PayPal IPN通知,它很健壮,很容易使用。阅读本文后,我搜索了另一个简单的教程并找到了一个。稍微调整一下,我可以调整它在多项目(购物车)付款中,我会将链接发布为solution@eldblz
