I’d like to verify that I’m attempting to do this the correct way and also get additional clarification on how to access the donation amount in my php auto action code.

I have a CBSubs donation plan setup that allows the user to specify a donation amount. Essentially what I’d like to do is have an Auto Action setup to execute php code that will write that donation amount out to an external database after the purchase is complete. I’ve used this post (www.joomlapolis.com/forum/255-developer-members-support/233410-solved-oncpayafterpaymentstatusupdateevent-and-var3) as an example, and have successfully utilized the onCPayUserStateChange trigger exactly as described in krileon’s initial reply to trigger the code when the donation payment is complete. This works even on repeat donations. It looks like the donation transaction must flip the [var2] User State to “A” / Active, and then sometime later revert back to a different state…and then back to “A” when the same user makes an additional donation. Nonetheless, combining that with the condition of a specific CBSubs plan ID # (as noted in the post) seems to work and trigger the code when the donation plan is purchased. What I’d like to do next is get the donation amount into my php code so that I can write it out to an external database. Is there a way to access the donation amount in my php code? The purchase of the donation plan can potentially be combined with the purchase of other subscription or merchandise plans, so the basket amount may not represent the donation amount. Of course there will always only be 1 donation purchase in any basket, but even when combined with other purchases I need the value of that specific donation.

Thanks,

I was not able to get the onCPayPaymentItemEvent to trigger given the conditions you suggested. But I am already doing a ‘code’ action with ‘php’ method. I need to do it this way in order to write the donation value out to my cloud external database. So I experimented with your first suggestion of using the onCPayAfterPaymentStatusUpdateEvent trigger. If I’m understanding this correctly, onCPayAfterPaymentStatusUpdateEvent will trigger whenever there is a payment status change…and as long as there are no further conditions associated with the auto action, it will trigger regardless of what’s in the basket. It will even trigger if there is an invalid payment transaction status change, such as a cancelled payment. But for a valid paid transaction, the $unifiedStatus (i.e.[var4]) should return “Completed”. So as long as I check for a completed transaction and then look at the basket items I should be able to pull in, and process, the donation value. Is that basically correct?

But I’m have having problems accessing the basket items and many of the return values from the event trigger in my php code . From this link (www.joomlapolis.com/documentation/18358-using-cb-triggers) and the definition of the function as
$_PLUGINS->trigger( 'onCPayAfterPaymentStatusUpdateEvent', array( &$user, &$paymentBasket, &$subscriptions, $unifiedStatus, $previousUnifiedStatus, $eventType, &$notification ))
It looks like when I specify [var2] in my php code it is replaced with &$paymentBasket, which is a pointer to an array. How do I index into those arrays?

$FirstBasketItem = [var2][0];
Doesn’t seem to work.

$NewPaymentStatus = [var4];
As a non-array value, this does return “Completed”, which is the correct payment status after a valid payment transaction.

Finally, are there examples or documentation of any of this on joomlapolis.com?

Thanks,
Jim

I have a follow-up on this thread.

I’m trying to understand conceptually how the PayPal communication takes place and how / when the onCPayAfterPaymentStatusUpdateEvent event gets triggered, as I’m getting some odd results under certain situations.

My situation: I have implemented this Auto Action Trigger on three different websites…one is a non-public website behind on my local network, the other two are public sites use for testing. The auto action is relatively simple (summary code included below), where the php code is triggered onCPayAfterPaymentStatusUpdateEvent. The code looks for “Completed” PayPal transactions and then looks for a specific plan ID (the ID of my donation plan), and then gets the donation amount and writes that to cloud storage.

When testing this on all three systems (all in different tabs of the same browser) I received odd results in that it would work on one site at one moment, but then not a bit later. Just very inconsistent. Also, up until today, I was able to get this to work on the non-public website as well, but today I’m receiving an “incorrect PayPal address” error from PayPal on this site.

Questions:

How does the communication flow between the website and PayPal? I’ve set the IPN and PDT (Payment Data Transfer) correctly back at PayPal, but I noticed that the URLs set within PayPal don’t seem to matter in the communication flow or return of payment data with CBSubs.

In addition, with the first site not being public, how does the PayPal information get received by this website? Should the PayPal transaction even work correctly with a non-public site? I don’t fully understand how it worked in the past and returned correctly to my private website from PayPal.

When exactly does the onCPayAfterPaymentStatusUpdateEvent get triggered…when the customer returns to my site from PayPal in their browser?

How does the browser session factor into this functionality? I seem to get inconsistent results if I run transactions on my websites from different tabs within the same browser, and seemingly consistent results if I run transactions on my sites from completely different browsers (Chrome, Firefox, etc.)

Thanks,
Jim
