IPN paypal

[AxelHack]

salve a tutti, ho utilizzato l'ipn di paypal per il mio sito, avendo aggiornato il php da 5.3 a 5.5 non funziona più la funziona sqlsrv_query apposto di essa ho usato odbc_exec che dovrebbe funzionare, invece non aggiorna nulla al database, la connessione con odbc_connecct funziona tutto okay, ma il resto no potete aiutarmi perfavore?

<?php    error_reporting(E_ALL);        // Require the configuration file    require_once('../config.php');        // The current time    $time = date("F j, Y, g:i a"); 
    // The database connection info    //$connection_info = array("UID" => $DATABASE_USER, "PWD" => $DATABASE_PASS, "Database" => $USER_DATABASE);    $conn = odbc_connect("Driver={SQL Server};Server=$DATABASE_HOST;Database=$USER_DATABASE",$DATABASE_USER,$DATABASE_PASS) or die('Database Connection Error!');    if(!$conn){        exit("Connection failed:".odbc_errormsg());    }     // Connect to the server    //$con = sqlsrv_connect($DATABASE_HOST, $connection_info);
    if (!$conn) die ("failed");    // The e-mail of the user submitting the payment    $payer_email = isset($_REQUEST['payer_email']) ? $_REQUEST['payer_email'] : die("Payer email value not set!");        // The email of the user receiving the payment    $receiver_email = isset($_REQUEST['receiver_email']) ? $_REQUEST['receiver_email'] : die("Receiver email value not set!");        // The payment status    $payment_status = isset($_REQUEST['payment_status']) ? $_REQUEST['payment_status'] : die("Payment status value not set!");        // The amount paid    $amount_paid = isset($_REQUEST['mc_gross']) ? $_REQUEST['mc_gross'] : die("Amount paid value not set!");        // The tax paid    $tax_paid = isset($_REQUEST['tax']) ? $_REQUEST['tax'] : die("Tax value not set!");        // Check if the payment status is completed, and the receiver email matches that in the configuration    if ($payment_status == "Completed" && $receiver_email == $PAYMENT_EMAIL) {                // The custom field set, to verify the correct details        $custom_variable = isset($_REQUEST['custom']) ? $_REQUEST['custom'] : die("Custom value not set!");
        // Split the field to an array        $custom_array = explode(":", $custom_variable);                // The User ID        $user_id = $custom_array[0];                // The custom amount paid        $custom_paid = $custom_array[1];                $insert_amountpay=odbc_exec($conn, "INSERT INTO PS_UserData.dbo.DonationTest (message, UserId) VALUES ('Amount paid: '$amount_paid', Custom paid: '$custom_paid ', Tax: ' $tax_paid '!', ' $user_id ')");                // Check if the product id exists        if (isset($DONATION_VALUES[$custom_paid])) {                        // The entry            $entry = $DONATION_VALUES[$custom_paid];                            $insert_tax=odbc_exec($conn, "INSERT INTO PS_UserData.dbo.DonationTest (message) VALUES ('Tax paid: '$tax_paid'!')");                        // Calculate the expected amount            $expected_amount = ($tax_paid != 0 ? ($amount_paid + $tax_paid) : $amount_paid);                        // Check the price and amount paid match            if ($custom_paid == $expected_amount) {                                $pagamento = odbc_exec($conn,"INSERT INTO PS_UserData.dbo.DonationTest (message, UserId) VALUES ('Points added: '$entry ' ! to', '$user_id')");                                                // The amount of points to give                $points = $entry;                                    // Check if the connection failed                if (!$conn) die("Connection to the database failed!");                                    // The query                                $updatepoints = odbc_exec($conn, "UPDATE PS_UserData.dbo.Users_Master SET Point += '$points' WHERE UserId = '$user_id'");                                                    // End the script                die("Donation successful! '$points' has been added to: ' $user_id'");            } else {                die("Request tempered! Mismatching payment amount!");                }        } else {                die("Value not found!");            }    }    odbc_close($conn);?>

fino quando c'era la funziona sqlsrv_query funzionava, effettuando questa modifica in odbc_exec non funziona più, usando il sandbox comunica con ipn e manda tutto il necessario, però alla verifica delle query non funziona.

Utilizzo php 5.5.36 ed sql server 2012

Grazie ancora
