javascript - 支付成功后无法找回Paypal信息

我正在尝试在销售网站上集成 Paypal 付款。客户部分运作良好，客户付款，钱存入卖家账户。第二部分允许恢复交易编号、金额、客户地址等数据，但不起作用。但我使用 Paypal 提供的脚本。

此文件index.php用于支付作品

hello, according to the advice of PHPology I set up the return call URL and of course used the PAYPAL script. I went to the history of IPN messages and I have an HTTP 500 error. I think there may be a syntax error in the PAYPAL script they are specialists in this kind of error.

     <?php
    function ipn($ipn_data) {

    define('SSL_P_URL', 'https://www.paypal.com/cgi-bin/webscr');
    define('SSL_SAND_URL', 'https://www.sandbox.paypal.com/cgi-bin/webscr');
    $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']);
    if (!preg_match('/paypal\.com$/', $hostname)) {
        $ipn_status = 'Validation post isn\'t from PayPal';
        if ($ipn_data == true) {
            //You can send email as well
        }
        return false;
    }

    // parse the paypal URL
    $paypal_url = ($_REQUEST['test_ipn'] == 1) ? SSL_SAND_URL : SSL_P_URL;
    $url_parsed = parse_url($paypal_url);

    foreach ($_REQUEST as $field => $value) {
        $post_string .= $field . '=' . urlencode(stripslashes($value)) . '&';
    }
    $post_string.="cmd=_notify-validate"; // append ipn command
    // get the correct paypal url to post request to
    $paypal_mode_status = $ipn_data; //get_option('im_sabdbox_mode');
    if ($paypal_mode_status == true)
        $fp = fsockopen('ssl://www.sandbox.paypal.com', "443", $err_num, $err_str, 60);

        $fp = fsockopen('ssl://www.sandbox.paypal.com', "443", $err_num, $err_str, 60);

    $ipn_response = '';

    if (!$fp) {
        // could not open the connection. If loggin is on, the error message
        // will be in the log.

最佳答案

我解决了这个问题。 Paypal 提供的脚本由于存在语法错误而无法运行。他们对这些方法的解释非常晦涩。最后，在进行一些语法和 url 修改后，我的 php IPN paypal IPN 监听器软件开始工作。

$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
$value = trim(urlencode(stripslashes($value)));
$req .= "&$key=$value";
}

//mysqli_query($dbconn,"INSERT INTO paytest (mess) VALUES ('$req')");
