PayPal Express Checkout Using NVP 84.0 [Support Thread]

[apollowilcox]

- Zen Cart version
- Additional plugins that might have altered /YOUR_ADMIN/orders.php
- Any debug-logs generated?

UPDATE: Did you see the screenshot that's present in this thread's first posting? The PayPal status history displays in the upper greyed-out section of the orders page, not as part of the orders status history.

Thanks Lat9:

- Ver 1.5.3.
- Other mods: I should have thought to check this - I'm sure we have at least 1, e.g. UPS Tracking... I'll look into this. Thank you for mentioning.
- Debug Logs - hadn't seen any specific to this, but i haven't looked very recently. Another great idea that I'll follow up upon.

Again, thank you. You mentioned looking closer in the a.m., but feel free to let me pursue these suggestions before you invest more of your time.

Much obliged,

Matt

No debug logs.
Also, while we do have some other mods affecting admin/orders.php, I uploaded the vanilla file as a quick check and have the same issue.

Upon further digging, I found two more pieces of info:
1. If I go back far enough (pre 7/13/15), the orders page looks right - it does display multiple paypal transactions for an order. So admin/orders.php seems to be okay.
2. So I looked at the table paypal_payment_status_history. The table has no records since 7/13/15. I have no idea what may have happened that day to stop that table from updating, but according to my search in Developer Tools, only two files use that table: /ipn_main_handler.php and /admin/paypal.php.

My ipn_main_handler is identical to the mod version (winmerge). /admin/paypal.php is vanilla from ZC 1.5.3. Nonetheless, I re-uploaded both files and tested. Still no updates to paypay_payment_status_history.

Any ideas?

Thanks.

It sounds like you need to "get to the bottom of" why the paypal_payment_status_history table has stopped updating. When the ipn_main_handler updates that table, it also updates the paypal table and adds a record to the associated order's status history.

Do these orders that "don't display fully" include the orders-status-history update associated with the PayPal transaction?

I agree. And yes - the paypal table is properly updated each time.

How about the orders-status-history record? Is that created?

[apollowilcox]

Yes. All of the order detail on the admin/orders-edit page is complete and accurate.

Since Zen Cart v1.5.5 includes a modified version of the PayPal Express Checkout (paypalwpp.php) module that uses the PayPal NVP 124.0 API, I'm declaring that this plugin is not supported for Zen Cart versions v1.5.5 and later.
