Paypal Ipn Problem


Langstra

Recommended Posts

I successfully implemented paypal ipn on my website, I tested it on the paypal sandbox and everything worked. Then I changed the url from https://www.sandbox..../cgi-bin/webscr to https://www.paypal.com/cgi-bin/webscr. This should be standard procedure and everything should work fine.

Once again, when using the sandbox provided by paypal, there are no problems.

 

Now a few of my customers tried to buy things and nobody got there items. In my database I log everything and I logged this error:

http error=Unknown SSL protocol error in connection to www.paypal.com:443

 

I use paypal ipn for the payment, underneath will be the ipn.php (ipn call back script that paypal will post variables to when a payment has been done)

//Original source: https://cms.paypal.com/cms_content/US/en_US/files/developer/IPN_PHP_41.txt
//Modified sample code by Codex-m: http://www.php-developer.org
//WORKING DEMO HERE: http://www.php-developer.org/paypal_ipn_demo/
//Use your Paypal Sandbox buyer account to test.
$req = 'cmd=' . urlencode('_notify-validate');
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
//NEW CODE: using Curl instead of fsockopen
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://www.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Host: www.sandbox.paypal.com'));
$res = curl_exec($ch);
//assign posted variables to PHP variables
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$account=$_POST['custom'];
$productname=$_POST['item_name'];
$txn_type=$_POST['txn_type'];
$trans_id=$_POST['transaction[0].id'];
$trans_id_2=$_POST['transaction[0].id_for_sender'];
//Check if any error occured
if(curl_errno($ch)) { //HTTP ERROR occurred
//Log error to database for troubleshooting
$log='http error='.curl_error($ch); //Here the error message gets build
db_write($log); //Here it gets written to the database
} else {
//NO HTTP ERROR OCCURRED, CLEAN
//CHECK IF VERIFIED
if (strcmp ($res, "VERIFIED") == 0) {

Unfortunately, an "Unknown SSL protocol error in connection to www.paypal.com:443", with "Unknown" being the keyword, error is rather difficult to decipher.

 

You say "a few customers"... so not all customers, correct?  If so, then it might just be a temporary issue with Paypal.  Have you run a test purchase yourself to verify all systems are a go?

Sorry I meant a few of my customers as in, I got 100% customers and 10% of them bought something using paypal. Every customer using it got the problem.

 

Was it spread out over a period of time?  Or was each purchase made relatively close to eachother, ie. all happened within an hour.

 

And, have you tried again since?
