Php Paypal IPN未更新数据库

我已经阅读了许多已经提交的帮助请求，但没有一个对我有帮助。所以我正在提交我的代码，看看是否有人可以帮助我

所以，当我做一个沙箱测试时，IPN得到了验证，但我的代码没有运行。有人能帮我吗

我之所以要更新，是因为当有人单击“购买”按钮时，它会在paypal中输入一个自定义字段，并带有一个记录id以进行跟踪，这是可行的，但不会被更新

IPNListener.php：

    <?php

    require_once("MAILER/smtpservice.php");

    function Connect()
    {
     $dbhost = "localhost";
     $dbuser = "root";
     $dbpass = "root";
     $dbname = "server";

     // Create connection
     $conn = new mysqli($dbhost, $dbuser, $dbpass, $dbname) or die($conn->connect_error);

     return $conn;
    }

    $conn = Connect();

    class PayPal_IPN {

function ipn($ipn_data) {
    define('SSL_P_URL', 'https://www.paypal.com/cgi-bin/webscr');

    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;

    }

    // get the correct paypal url to post request to
    $paypal_mode_status = $ipn_data; //get_option('im_sabdbox_mode');
