PayPal Issue - Ugraded from 1.3.8a to 1.3.8f

[harry2cool]

I just upgraded to 1.3.9f.

Paypal Ipn module was working on the test server.

However after my production server went live Paypal payments do not return a new order id.

I do receive the payment and my older order is shown in instead of a new one being generated.

Where could I be possibly wrong.

Help appreciated.

Sounds like you missed one or more files when upgrading.

I am developer worked for harry2cool and we meet the order id display issue using paypal payment method at 1.3.9f zen-cart version. it shows old order id instead of new one on successful page. We have upload all files and checked again.
Do you think maybe it cause by below reason:
1, The ipn_main_handler.php process a little slower then redirect to successful page, so the new order id does not put into $_SESSION['order_number_created'] parameter.

Yes, definitely.

That is why using Website Payments Standard is NOT recommended. Express Checkout is much better.

This issue did not occur on 1.3.8a version of zen-cart, but on 1.3.9f, maybe there are some work flow changes on 1.3.9f?

A new customer gets a blank order id on the success page, however it is passed in the admin/database.

If you're getting blank pages, then you've got PHP errors. When I search for "blank page" in the Tutorials/FAQ area I see this article: https://www.zen-cart.com/tutorials/index.php?article=82

[jarvis_ht2000]

No,No, we got blank order id not blank page. It means the ipn_main_handler.php file does not put order into database before redirect to successful page. It happed after upgrade zen-cart to 1.3.9f version. Are there some work flow change at this version?

[DrByte]

Yes, a LOT has changed: all improvements. And most are attempts to try to make paypal's unreliable IPN service work more reliably.

A better solution is to use Express Checkout instead, since it does NOT have to rely on an IPN to create an order in the database. (Express Checkout creates the order immediately when it is paid, and while the customer is on the site, instead of having to wait for PayPal to tell the store about the order via an IPN in the background.)

[harry2cool]

Dr Byte, your suggestion to use Paypal Express Checkout WORKS.

It's a much more better process than the the IPN, it's strange I was not aware of this.

Thanks for all the help.

Jarvis we are done dude :)
