}
?>

the problem is this code is working 100% fine for sandbox now what i did for live version is to change the merchant email to client email and paypal_mode to false for live testing and one other thing i changed the

`$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');

in the ipn class to

`$ch = curl_init('https://www.paypal.com/cgi-bin/webscr');`

for live mode i have used ipn simulator to validate my file and it is ok more over i am sure about the ipn path i set in paypal for merchant that is also ok am sure of it, i dont know whats wrong! can anybody point me on the right direction?

Answer 1

As per downloading the newer PHP IPN code from here. You save the IPN class file to whereever you need it (exampled below in the same folder as your IPN file.

You will also need to setup a Exception catching routine as Paypal don't implement one by default (that's what the try{ ...} catch{} block does).

<?php
define("LOG_FILE", "paypal_ipn.log");
////edit
error_log("Log File Started:\n",3,LOG_FILE);

require('PaypalIPN.php'); //check path is correct. 
$ipn = new PayPalIPN();    
try {
    // Use the sandbox endpoint during testing.
    $ipn->useSandbox(); //comment this line out to use live version.
    $verified = $ipn->verifyIPN(); //returns true or false. 
    if ($verified) {
        /*****
         * Process IPN
         * A list of variables is available here:
         * https://developer.paypal.com/webapps/developer/docs/classic/ipn/integration-guide/IPNandPDTVariables/
         *
         * Here is where you add your data from your current setup, your own custom data to take the values from Paypal and process them.
         ****/
        // check whether the payment_status is Completed
        // check that txn_id has not been previously processed
        // check that receiver_email is your Primary PayPal email
        // check that payment_amount/payment_currency are correct
        // process payment

        // assign posted variables to local variables


        $price       = $_POST['mc_gross'];
        $currency    = $_POST['mc_currency'];
        $payer_email = $_POST['payer_email'];
        $txn_id      = $_POST['txn_id'];

        $item_name = $_POST['item_name'];
        if ($item_name == "Small Bundle Plan") {

            $item_name = "small";
        }

        parse_str($_POST['custom'], $_MYVAR);

        $custom    = $_MYVAR['id'];
        $unique_id = $_MYVAR['unique_id'];
        trim($custom);
        $txt           = $custom;
        $currency_code = $_POST['currency_code'];
        $fulldate      = gmdate('Y-m-d H:i:s');
        if ($txn_id) {

            $query = "UPDATE `puppy_pending_transaction` SET `status`=? WHERE unique_id=?";
            $stmt  = $db->prepare($query);
            if ($stmt) {
                $stmt->bind_param("ss", $status2, $unique_id);
                $stmt->execute();
                $stmt->close();
            }


            $query = "INSERT INTO `puppy_transaction_confirmed`(`transaction_id`,`unique_id`, `user_id`, `payer_email`, `transaction_time`, `package`, `amount`, `currency`,`status_delivery`) VALUES (?,?,?,?,?,?,?,?,?)";
            $stmt  = $db->prepare($query);

            if ($stmt) {
                $check = $stmt->bind_param("sssssssss", $txn_id, $unique_id, $custom, $payer_email, $fulldate, $item_name, $price, $currency, $status);
                $stmt->execute();
                $stmt->close();
            }

            $query = "INSERT INTO `puppy_paid_transaction_record`(`unique_id`, `month_delivered`, `total`,`status`) VALUES (?,?,?,?)";
            $stmt  = $db->prepare($query);
            if ($stmt) {
                $stmt->bind_param("ssss", $unique_id, $zero, $item_name, $status3);
                $stmt->execute();
                $stmt->close();
            }

            /***
             * End OP code
             ***/
        }
        // Reply with an empty 200 response to indicate to paypal the IPN was received correctly.
        header("HTTP/1.1 200 OK");
    }

}
catch (Exception $e) {
    error_log("There was a problem: ".$e->getMessage(),3,LOG_FILE);
}

I also highly recommend you download the associated .pem file and upload it to your server and adjust the reference to it on line 106 of the IPN class file. This pem file has a key for your server to communicate with the Paypal secure server and solves a large batch of historic problems relating to this.

You may need to tweak some of your own code for editing the incoming data but this script works for me much better than the older procedural Paypal code did.

.pem file clarification:

I may be easiest for at least testing perspective to simply have the Paypal Pem file in the same folder as you keep your paypal IPN class.

so line 106 of the class:

    if ($this->use_local_certs) {
        curl_setopt($ch, CURLOPT_CAINFO, "cacert.pem");
    }

and ensure that $this->use_local_certs = true;.
