  1. Thanks Michael! I just tested it this morning and it definitely works fine now. I won't be having many more headaches for a while now. I owe you a few rounds for that
  2. Well, I seem to be getting closer to solving this conundrum. Apparently, PayPal are planning to drop support for HTTP 1.0 for IPN, starting February 2013. Yet they've configured the sandbox to turn off support early. I've fixed up the code a bit so that it validates www.sandbox.paypal.com as the host: $header = "POST /cgi-bin/webscr HTTP/1.1\r\n"; $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; $header .= "Content-Length: " . strlen($req) . "\r\n\r\n"; $header .= "Host: www.sandbox.paypal.com\r\n"; fputs($fp, $header . $req); Part of the IPN process seemingly goes through, but then it hits another 400 error midway. Then the request fails to go through. Here's my latest error log that ipn.txt has produced: --- Received: Array ( [txn_type] => subscr_signup [subscr_id] => I-S74MY3AY6RFJ [last_name] => Powers [residence_country] => GB [mc_currency] => USD [item_name] => Knowledge is Power Membership [business] => seanpw_1345583968_biz@eternalrain.org [amount3] => 10.00 [recurring] => 1 [verify_sign] => A5S6uY74MvuexX795XG3CdYBOgQIAlUhrT9xU-RcnexACTDCtGUiDue8 [payer_status] => verified [test_ipn] => 1 [payer_email] => smaug1_1345584245_per@eternalrain.org [first_name] => Sean [receiver_email] => seanpw_1345583968_biz@eternalrain.org [payer_id] => LBG3RR7LYFWJ2 [reattempt] => 1 [subscr_date] => 10:22:48 Aug 27, 2012 PDT [btn_id] => 2578773 [custom] => 23 [charset] => windows-1252 [notify_version] => 3.5 [period3] => 1 Y [mc_amount3] => 10.00 [ipn_track_id] => cc2f701aa1fcd ) Sent: POST /cgi-bin/webscr HTTP/1.1 Content-Type: application/x-www-form-urlencoded Host: www.sandbox.paypal.com Content-Length: 662 cmd=_notify-validate&txn_type=subscr_signup&subscr_id=I-S74MY3AY6RFJ&last_name=Powers&residence_country=GB&mc_currency=USD&item_name=Knowledge+is+Power+Membership&business=seanpw_1345583968_biz%40eternalrain.org&amount3=10.00&recurring=1&verify_sign=A5S6uY74MvuexX795XG3CdYBOgQIAlUhrT9xU-RcnexACTDCtGUiDue8&payer_status=verified&test_ipn=1&payer_email=smaug1_1345584245_per%40eternalrain.org&first_name=Sean&receiver_email=seanpw_1345583968_biz%40eternalrain.org&payer_id=LBG3RR7LYFWJ2&reattempt=1&subscr_date=10%3A22%3A48+Aug+27%2C+2012+PDT&btn_id=2578773&custom=23&charset=windows-1252&notify_version=3.5&period3=1+Y&mc_amount3=10.00&ipn_track_id=cc2f701aa1fcd Received: HTTP/1.1 200 OK Received: Date: Mon, 27 Aug 2012 17:29:52 GMT Received: Server: Apache Received: X-Frame-Options: SAMEORIGIN Received: Set-Cookie: c9MWDuvPtT9GIMyPc3jwol1VSlO=bWQzBFA8HBkKg8ljA6rF-kzqIPUDWfTJ-s1hG0J90WLFZAyxzYDH16KsD3WY9xJUPiTy6AF06KvR_kLSYcGOuywTORTBHsqE-8jtV09BNNsiKIyEYOk40hvC0YkExostCOaTa0%7cL4rey604uUdT9zkdK7aT-5ztzfDtT9rnOQVHV6IsWDznR7fJb67gLy0h2iEfoK273nQQA0%7cyOouS-6v5pDCMLCpjtiU4FrXs6OAtHhZPJ40zQHP1zwAWlVW4kRZCoFUswoObQ5YFMGsQW%7c1346088592; domain=.paypal.com; path=/; Secure; HttpOnly Received: Set-Cookie: cookie_check=yes; expires=Thu, 25-Aug-2022 17:29:52 GMT; domain=.paypal.com; path=/; Secure; HttpOnly Received: Set-Cookie: navcmd=_notify-validate; domain=.paypal.com; path=/; Secure; HttpOnly Received: Set-Cookie: navlns=0.0; expires=Sun, 22-Aug-2032 17:29:52 GMT; domain=.paypal.com; path=/; Secure; HttpOnly Received: Set-Cookie: Apache=10.72.109.11.1346088592145913; path=/; expires=Wed, 20-Aug-42 17:29:52 GMT Received: X-Cnection: close Received: Transfer-Encoding: chunked Received: Content-Type: text/html; charset=UTF-8 Received: Received: 8 Received: VERIFIED Received: 0 Received: Received: Array ( [transaction_subject] => Knowledge is Power Membership [payment_date] => 10:31:52 Aug 27, 2012 PDT [txn_type] => subscr_payment [subscr_id] => I-PA7GM537VAHV [last_name] => Powers [exchange_rate] => 0.486111 [residence_country] => GB [item_name] => Knowledge is Power Membership [payment_gross] => 10.00 [mc_currency] => USD [business] => seanpw_1345583968_biz@eternalrain.org [payment_type] => instant [protection_eligibility] => Ineligible [verify_sign] => AKHFr8--kVOqhVOa1C0DPHdDlFWrADo4BhY7X.Tb7aaAafZGaEnkBRip [payer_status] => verified [test_ipn] => 1 [payer_email] => smaug1_1345584245_per@eternalrain.org [txn_id] => 19B157050C148792J [receiver_email] => seanpw_1345583968_biz@eternalrain.org [first_name] => Sean [payer_id] => LBG3RR7LYFWJ2 [receiver_id] => AANK57TL69S8S [settle_amount] => 4.55 [settle_currency] => GBP [payment_status] => Completed [payment_fee] => 0.64 [mc_fee] => 0.64 [mc_gross] => 10.00 [custom] => 24 [charset] => windows-1252 [notify_version] => 3.5 [ipn_track_id] => 8395752361bc8 ) Sent: POST /cgi-bin/webscr HTTP/1.1 Content-Type: application/x-www-form-urlencoded Content-Length: 889 Host: www.sandbox.paypal.com cmd=_notify-validate&transaction_subject=Knowledge+is+Power+Membership&payment_date=10%3A31%3A52+Aug+27%2C+2012+PDT&txn_type=subscr_payment&subscr_id=I-PA7GM537VAHV&last_name=Powers&exchange_rate=0.486111&residence_country=GB&item_name=Knowledge+is+Power+Membership&payment_gross=10.00&mc_currency=USD&business=seanpw_1345583968_biz%40eternalrain.org&payment_type=instant&protection_eligibility=Ineligible&verify_sign=AKHFr8--kVOqhVOa1C0DPHdDlFWrADo4BhY7X.Tb7aaAafZGaEnkBRip&payer_status=verified&test_ipn=1&payer_email=smaug1_1345584245_per%40eternalrain.org&txn_id=19B157050C148792J&receiver_email=seanpw_1345583968_biz%40eternalrain.org&first_name=Sean&payer_id=LBG3RR7LYFWJ2&receiver_id=AANK57TL69S8S&settle_amount=4.55&settle_currency=GBP&payment_status=Completed&payment_fee=0.64&mc_fee=0.64&mc_gross=10.00&custom=24&charset=windows-1252&notify_version=3.5&ipn_track_id=8395752361bc8 Received: HTTP/1.0 400 Bad Request Received: Server: BigIP Received: Connection: Keep-Alive Received: Content-Length: 19 Received:
  3. Found out what part of the problem was. My payment settings were set to ask first before converting currencies, so payment status was always set to pending. Just set it to "Convert automically". Still getting error 400 codes, though.
  4. I've checked my IPN history, and they seem to be being sent successfully. But here's the thing - the request's being sent out twice. Once for a transaction, which it accepts, and another for a recurring payment profile. Is this normal?
  5. Hi Larry and all, it's me again. I have a problem getting the IPN script to work properly. The IPN request is sent successfully, but the ipn.php script doesn't seem to be updating the database. I've checked my code against the one provided on this site, but I don't seem to be finding anything wrong with mine. Wrote in the function that logs IPN requests, and interestingly it reports back a HTTP 400 error code. Is there something I've missed or done wrong? Or could it be an issue with my host? Thanks for any help offered! <?php # Script 1.22 - ipn.php // Include the configuration file: require ('includes/config.inc.php'); // Open the text file: // Change this path to make it accurate. // The text file must be writable by PHP! $file = fopen('../../ipn.txt', 'a'); // Write the POST data to the file: fwrite($file, "Received:\n"); fwrite($file, print_r($_POST, true)); fwrite($file, "\n"); // Create a request variable: $req = 'cmd=_notify-validate'; // Add each received key=value pair to the request: foreach ($_POST as $key => $value){ $value = urlencode(stripslashes($value)); $req .= "&$key=$value"; } // Open a socket connection to PayPal: $fp = fsockopen('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30); // Test // If no connection was made, trigger an error: if (!$fp){ trigger_error('Could not connect to the IPN!'); // If a connection was made, send the request to PayPal: } else { $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) .

  6. Disregard this topic, I've fixed it now. I didn't include the login.inc.php file in my index.
  7. Hi Larry and all! I'm up to Chapter 4, User Accounts, creating a login form for the site. I can access it on index.php, but when I try to test it... nothing happens! No errors, not even a login confirmation. I've tried debugging it with the examples provided by this site, and I'm still having the same problem. Is it possible that one of my includes is causing this bug in some way? Thanks for anyone who helps me out!

But I'm posting it anyway just in case.) <?php # Script 1.7 - form_functions.inc.php // Define the function function create_form_input($name, $type, $errors){ // Check for and process the value: $value = FALSE; if (isset($_POST[$name])) $value=$_POST[$name]; // Strip the magic quotes: if ($value && get_magic_quotes_gpc()) $value = stripslashes($value); // Check the input type: if (($type == 'text') || ($type == 'password')){ // Create the input: echo '<input type="' . $type .

  8. Nevermind, I found out what the problem was - I was trying to link function.js to a non-existant directory. I've fixed it now, so it's now working as it should.
  9. Yes, I tried the same scripts in Internet Explorer, and still had the same problem.
  10. Hi there. I've been working through this book trying out the example scrips shown within, however I've recently come across a problem in chapter 11, Web Application Development. On images.php, none of my links will open up in a popup window, as is the intended action. I've tried copying the scripts as close as possible, and even tried comparing my scripts (function.js, images.php, show_image.php) with the hosted files, but still came up stumped. I've even tried downloading and running the example files myself, and even they won't work. I should also mention that I haven't attempted Script 11.6 yet with the updated images.php code, as I'm too busy pulling my hair out trying to pin down where I'm going wrong.
