I just realized that my paypal ipn handler in php doesn’t work anymore (and I change nothing), I use the sample php script provided by paypal.

I tried to isolate the problem by making several test, and at this time I can say that the problem is not the “VERIFIED” or the “INVALID” thing but comes from these lines:

[…]

fputs ($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0)
        {
        // check the payment_status is Completed

[…]

Anyone know if paypal change something or why it doesn’t work?

thanks’

ps: if I put my code before all the paypal tests (before the line “if (!$fp)”) it just works fine

This is my code, I comment where the “database process” works and where it doesn’t.

<?php

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

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

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

// assign posted variables to local variables
$payment_status = $_POST['payment_status'];


// DATABASE PROCESS WORKS (BEFORE THE PAYPAL TESTS)



if (!$fp)
{
    // HTTP ERROR
}
else
   {

// DATABASE PROCESS WORKS

    fputs ($fp, $header . $req);
    while (!feof($fp))
    {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0)
        {
            // check 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


// DATABASE PROCESS NOT WORKING

        }
        else if (strcmp ($res, "INVALID") == 0)
        {
            // log for manual investigation

// DATABASE PROCESS NOT WORKING
        }
    }
fclose ($fp);
}
