I just want to know if there is a Full Version with all the bug fixes.

 

I've already opened a few files with nothing in them. I don't read Dutch.

Hi,

 

After a lot of study, I succeeded in getting Paypal_IPN working.

I discovered errors in the file /catalog/paypal_ipn.php that was added august 2009 to contribution number 2679.

 

Below is the whole file in the form which I use.

Please read my release notes in the file header.

 

I also made the language files for Dutch, ask me if you want them.

 

 

The original (English) Install instructions are not included in most of the packages; I found them in the package "PayPal IPN Module 2.3.4.7" of 4 Mar 2009.

Later versions include only a small text in German.

 

Eveline

Hello,

 

I've a problem with IPN. When I config payment and click on the button to come back on my shop, it says my order was successfully recorded.

It's the case but ...

Payment status is already on pending, no information in comments from paypal.

 

I've turned ON register globals and add a php.ini file in the paypal ipn ext folder but it's the same thing.

 

Configuration :

- Local installation (Windows XP)

- Wamp server with : Apache 2.2.11 // PHP 5.2.5 // MySQL 5.1.36

- OSC 2.2rc2a

- Paypal IPN v2.3.4.6

 

Thanks for help !

Payment status is already on pending, no information in comments from paypal.

 

This means that IPN is not reaching Your site.As IPN code is supposed to update order status and send email.

 

The probable reasons:

Improper IPN path.

IPN profile setting in Paypal disabled.

 

SO first step is make sure IPN are reaching where they should.

Hi, I'm using the Paypal IPN 2.3.4.7. I think I installed in correctly, but when I get to the paypal page, it shows a zero total and asks for an amount to be entered. Has anyone else encountered this issue and is there a fix? Basically, what am I doing wrong?

 

I am having the same problem. Any fix?

hi there,

 

i have just installed the paypal ipn addon version 2.3.4.7 (4th march 09) it works and i can recieve payments but the order status is not updating and not sending out emails.

 

i have searched the forums and there are many similar posts.

 

how can i fix this? i have no idea whats causing the problem. when i look at the IPN history in my paypal account and then message id i get retrying errors and the Notification URL is showing up as :https://www.mysite.co.uk/ipn.php?language=english i thought the ipn.php was supposed to be loacted in the ext/etc/etc?

 

i also have a dedicated ssl on the site if that makes a difference? the encrypted option is set to off.

 

thanks in advance

Having the same problem as in the post above. Not receiving any e-mails and the Comments field also remains blank. This is a serious problem for my shop.

 

As for my previous problem, fixed it by changing the Transaction Type.

I'm a bit confused. osCrc2a has a Paypal module (catalog>ext>modules>payment>paypal>standard_ipn.php). Isn't this all that's needed for IPN?

Ken - your confusion is understandable, but your assumption is wrong.

 

How it works is like this -

 

- Once the customer has entered checkout and chosen shipping, and shipping options (gift wrap, insurance etc), the next step is the payment method

 

- checkout_payments.php checks the customer address against the tax zones (geographic areas) for each payment method you have installed

- if the customer is in the allowed geo-zone for PayPal, it offers payPal as a payment method

- if the customer chooses PayPal, and goes to order confirmation, then checkout_confirmation.php assembles all the customer and order details and basically asks the customer if it is all correct, or if they want to edit anything. If they confirm it, then all that data is passed to /includes/modules/paypal_ipn.php

- /includes/modules/paypal_ipn.php then passes that data to PayPal and redirects the customer to the PayPal website to sign in and choose funding source etc. This part of the IPN also passes to PayPal the data return path for confirming payment has been transferred to the merchant's PayPal account.

- once the customer has done what's needed, and PayPal have moved the money to the Merchant's PayPal account, then the PayPal IPN server squirts a data stream back to your site - but the returned data goes to /ext/.../paypal_ipn.php NOT to /includes/modules/paypal_ipn.php

 

- /ext/.../paypal_ipn.php then records the payment details into the database and updates the order status and transaction record, I think it also confirms back to PayPal that the payment data was received from them, and failing to do so is one common cause of payment failures.

 

So the IPN has two parts -

- the first paypal_ipn.php which is the payment methods module, and sends the customer and order details to PayPal, this is in /includes/modules/

- the second paypal_ipn.php which is the response receiver and order updater, this one is in the /ext.../ folder

 

There is a third file in /includes/languages/{language-name}/modules/payments/paypal_ipn.php which controls the displayed language strings for the checkout pages and the admin payment modules page.

 

So .... nope, the /ext/.../paypal_ipn.php is not all that osC needs - it needs all three files for any individual payment processor's IPN in order for that payment processor's IPN to function - regardless of which payment processor you're using (e.g. MoneyBookers, NoChex, AlertPay, ppPay etc.n Google Checkout is a little different, as is Amazon Payments, but the idea is similar). Each set of files will be named after the payment processor they handle - e.g. MoneyBookers.php and so on.

 

Hope that helps?

 

Gaz

 

 

 

If any of the above is wrong, can someone post the correct process or logic - I think there's a few people get stuck with how the IPN's work.

Whoa - stop right there! In osC2rc2a there is no such code file as /includes/modules/paypal_ipn.php! So, having installed paypal website payments standard, I appear to have everything set up? All I appear to need to do is set up my profile to return to catalog/ext/modules/payment/paypal/standard_ipn.php?

OK, fair call - my bad, I was using generally understood shorthand pathing ... try this - /includes/modules/payment/paypal_ipn.php

 

Just for the record in RC2a ...

 

catalog/ext/modules/payment/paypal/standard_ipn.php

hooks up with

catalog/includes/modules/payment/paypal_standard.php

and

catalog/includes/languages/english/modules/payment/paypal_standard.php

 

Therefore as I originally answered - No your premise of the single file in /ext/.... is still incorrect, and my original answer SHOULD have given you enough information to track down the other two files of the trio. The overall process I described remains the same for the standard_ipn in RC2a, it's just handled slightly differently by the code.

 

Lastly, there perfectly well could be an /includes/modules/paypal_ipn.php in RC2a on a NON STANDARD install, which is actually the norm for osC sites - i.e. NON-standard (nobody uses it straight from the box and runs with it that way as a production site - that's just begging for hackers to visit your install).

 

All I appear to need to do is set up my profile to return to catalog/ext/modules/payment/paypal/standard_ipn.php?

 

You could do - if you only have one website, will only ever have one website, and that one website will only ever be the sole source of payments into your PayPal account (i.e. no instant payment buttons, no auction sites, no WordPress eShops etc etc etc) - otherwise, read the help files and the instructions - within osC, and at PayPal - enter your /ext/... path in there and EVERY IPN or PayPal Express callback confirmation from your PayPal account will be sent to your website, many will be irresolvable (because they did not originate from the IPN on your site) and could cause server resource abuse due to SQL query loops and timeouts, and your hosting account could get suspended (I've heard several stories of it happening).

 

If you ask for advice, listen to experience, and read between the lines if it's not an exact fit with your situation. Adapt what you're told to what you're experiencing ... and I do hope that's not "teaching granny to suck eggs"?

 

Alternatively - follow the osC forum credo - and post your full site and server spec with version numbers, plus screen shots of errors etc, then people who help you are not firing blindly and generically when they offer that help.

I build a shop for one of my customer. Now this shop receives 300-400 small orders each day. Many orders are done through paypal.

I am using paypal ipn latest version but have a big problem which is a real issue when receiving so many orders;

I know that we can not prevend a customer closing the paypal window after payment has been made.

But there must be a way that directly after paypals displays the screen where it confirms that the payment has been made the shop also

receives a message for this payment. The IPN notification is only send when customer goes back to the shop.

There must be something that can be done about this because manual check of all payments is impossible.

Hope someone can help.

There is no file paypal_ipn.php anywhere on the site.

 

Just for the record in RC2a ...

 

catalog/ext/modules/payment/paypal/standard_ipn.php

hooks up with

catalog/includes/modules/payment/paypal_standard.php

and

catalog/includes/languages/english/modules/payment/paypal_standard.php

 

Yes, that's all in position.

 

Lastly, there perfectly well could be an /includes/modules/paypal_ipn.php in RC2a on a NON STANDARD install, which is actually the norm for osC sites

 

There isn't on the two test sites I've set up using the full installation as downloaded.

 

You could do - if you only have one website, will only ever have one website, and that one website will only ever be the sole source of payments into your PayPal account (i.e. no instant payment buttons, no auction sites, no WordPress eShops etc etc etc) - otherwise, read the help files and the instructions - within osC, and at PayPal - enter your /ext/... path in there and EVERY IPN or PayPal Express callback confirmation from your PayPal account will be sent to your website, many will be irresolvable (because they did not originate from the IPN on your site) and could cause server resource abuse due to SQL query loops and timeouts, and your hosting account could get suspended (I've heard several stories of it happening).

 

According to paypal, if the calling program sends return URLs in the variables "notify_url" and "return" these will override the default return URLs set up in "Profile". This seems to work ok in paypal sandbox test environment for the two test osC sites I'm playing with at the moment.

 

As to "teaching granny to suck eggs", no problem. I'm always happy to learn from anybody with more experience than I. I hope you don't mind me pursuing what seems to be a bit anomalous.

I've now tried this with two live sites accessing the same Paypal account and with the variables "reply" and "notify_url" properly passed from each site. Absolutely perfect - no confusion. Both return to the correct checkout process and orders are correctly allocated and the shopping baskets cleared.

 

Hope this helps.

I have two OS Commerce shopping carts, both running Paypal IPN. One works fine. When the customer picks Paypal, they are given a split screen at Paypal.com where they can either enter there credit card info, or log into there Paypal account.

 

On the other cart, same setup but no matter what I do the customer can only log into Paypal.

 

Both Paypal accounts are business accounts, both can take credit cards.

 

I called Paypal on the not working cart and they said its something in my shopping cart, not on there end but I can't find anything wrong.

 

What am I missing here?

 

Thanks guys.

Log into your PayPal Account

 

Go To Profile>> Website Payment Preferences >> PayPal Account Optional. This should be checked "On"

I totally agree with what you say Martin. However, isn't it strange that one site was showing the split screen? I'd have thought that if "Paypal Account Optional" was 'off' then neither of his sites would have seen the split screen?

Hello forum.

 

I have a fairly big problem with getting the order status updates happening automatic. I am using the standard build in paypal module. And suddenly on 1 september at 12:10 the order updates stopped working. I have been testing a lot now and come to the following facts:

 

the ipn.php writes a ipn.txt with all the data from paypal which seems correct

 

in ipn history on paypal site all the notifications cause a http response code 500

when i discard the following check in ipn.php:(by adding || 1 == 1 to the if condition)

 

//Check both the receiver_email and business ID fields match

if (!$ipn->validateReceiverEmail(MODULE_PAYMENT_PAYPAL_ID,MODULE_PAYMENT_PAYPAL_BUSINESS_ID)) $ipn->dienice('500');

 

the notification does not cause the http response 500 error.

 

but still the order status is not updating automatic.

 

This is still displaying at the order status:

 

No PayPal Transaction Information Available(d4c201db922b26f9113c616dxxxxxxx)

 

I hope someone has encountered this problem before and can help me on my way with solving it.

 

Thanks for your time,

Yes Ken, but the OP infers that he has 2 PayPal accounts so perhaps one has the incorrect settings.

I have installed this contribution, but I can't quite seem to get it all figured out.

 

When I process the initial transaction and transfer to Paypal, I can see where an order is being created in my orders list - say order #190 for .01 in "preparing [paypal ipn] status. Then, I walk through the Paypal screens and when I click on the "confirm order" button in Paypal, a new order record is generated for me - order #191 fo .01. Everything about order #191 is identical to #190 including the preparing status.

 

If anyone has any ideas about what might be happening, or even thoughts about where I can begin looking, I would really appreciate it. I'm really pulling my hair out, and I really don't have that much more to spare!

 

Thanks!

Ah yes, of course. I missed the implication. Been so involved in settings for two carts accessing the same Paypal account my mind was pre-focussed. :blush:

Strange - I thought the confirm order button was on catalogue/checkout_confirmation.php - not at PayPal

 

I say that because it sounds like the checkout_confirmation order button is being activated twice or the checkout_confirmation.php page is being loaded twice (osC commits the order to the database when that page is loaded - including at a page refresh or if the back button is used to escape paypal). That's the most common cause of multiple records and order numbers for the same order.

 

Example - if your site "home currency" is not the same as the transaction currency, nor the "home currency" for your PayPal account, then rounding errors occur during the currency conversions, and even if only a few pennies, some customers will use the back button to check that the PayPal total is truly not the same as the one shown by checkout_confirmation - that will cause two orders to be logged on their account, in the database, and on the admin/Customers/orders page.

 

Other than that, I'd recommend you increase the level of server error logging to try and capture more information to point you to the culprit.

 

Sorry I can't be more helpful.

That was actually really helpful. As of my posting, I didn't even have a clue where to begin looking.... I will now dive into checkout_confirmation.php and see where I am going wrong.

 

Thank you very much for the tip!
