Update:
when it gets stuck on “Place Order”, the order actually gets placed, it appears in the back end and has a status pending although i never was able to get to the Paypal site to pay for it.

Update on the chained payments fix.

Like I’ve said before I don’t know php, and am not a programmer I only go by logic that I think may be true. I read the code, and sort of know what it does, but do not edit, unless I am following a tutorial or copy/paste from a trusted source.

With that being said, I am sort of proud of myself 🙂 for managing to get this working, or at least worked on the test purchase I made. Here is what I did, in case someone is experiencing similar issues and needs an option to try.

Jaime, please let me know if what I’ve done makes sense and if I should keep it like that, or you think there is a better way to go about this.

I was getting stuck on the Place Order page. Right after clicking the button it seemed like the site is trying to connect to PayPal but just kept trying with no luck. I knew it has something to do with the communication between the sites, but wasn’t sure where to look, or what to look for.

After circling around it for few hours, I decided to activate the debug mode in wp_config, and see if it may show something I can use.
With the debug=true, it showed an error on the checkout page, when trying to Place Order, that pointed to /var/www/mysite/wp-content/plugins/wcvendors/WCVendors/classes/gateways/PayPal_AdvPayments/PayPal_AP/classes/adaptivepayments-sdk/lib/auth/PPAuth.php

I downloaded the file on to my desktop to see what it may be.
What I also did is, I got the same file, but from Matt’s plugin directories.

Searched both files for references to PV_vendor, or WC, or Vendor and I didn’t find any in either of them, so I figured, let me override the WCVendors PPAuth.php file with the one from Matt’s plugin. No changes were made to either of the files.
I did save the original PPAuth.php from WCVendors, in case I need to go back to it.

When I did that…..drum roll….it worked. I was able to place the order and get to PayPal’s site for payment. I made a purchase with my sandbox credentials, and sure enough, it went through, and commission was deducted, and everything seemed to work fine.

The email that got sent to the buyer had some errors related to:

WCVendors/classes/class-shipping.php
WCVendors/classes/admin/emails/class-wc-notify-vendor.php
WCVendors/views/emails/admin-new-order.php

I also saw a reference in the class-shipping.php to Table Rate Shipping 2. Did you make WCVendors play nice with TRS2 or that’s a future plan?

Jamie, does that fix for the chained payments seem legit?

Hi Jamie,
Thanks for the fix.
I tested it with the file you provided, had the same thing happen, getting stuck in the place order stage.

Fixed it when I did the PPAuth replacement again. I guess I’ll just keep that fix. I remember I had “invalid transaction” error a while back and I got a developer to take a look at it and fix it. I was told at the time that it was related to crone. Is there a chance they may have changes something in the PPAuth?
I’ll ask them later today and post back here.

Sure thing.
I put them in a dropbox folder
https://www.dropbox.com/sh/66mawdcjsi1yq2x/AADGeOSXEyTEkLK4RxJdPZsZa

let me know if you have trouble accessing it.

Majaz,
I had this invalid transaction message a while back, and if I remember correctly the guy that worked on fixing it told me it was a cron issue, I did’not had it installed and working properly.

Your email warning messages: I had that too, and still not sure why it showed, but when the wp_config debug mode is off it does not show.

Hi Jamie,
I know you said you’re away, but I wanted to put this up here so you see it whenever you log back in.

After being able to make a sandbox payment, and all seemed to work fine, I now tried to switch to live credentials, and stuff is not working again…arrrgh.

I posted in a new tread, but I’ll repeat here, because I think it is relevant to the chained payments issue.

1) What happens if I want to sell products that are not by any vendor but by me (the website) meaning I may have stuff in stock that will be sold by me? How is that handled, do you know? Any suggestions?

2) I have put all the live credentials in place:
paypal email is the one I use to log in to paypal
API username is the one that I find in Profile>Selling Tools>API credentials
API pass and API signature are from the same place.
I have created an app for advanced payments and have put it’s ID in too.

However, I can’t seem to be able to checkout. It gives me Invalid Transaction Error.
When I get back to the page and try again, it gives me this

Error ID: 550001. User is not allowed to perform this action
Error ID: 580022. Invalid request parameter: payKey cannot be null

Is there anything else that needs to be done? As far as I know, that should be it…but for some reason not working as expected.

Update:

I contacted the person that sent me the PayPal app approval notice. There is a link next to the message with their nickname where you can click and view their profile, and send personal messages.

I send personal message and asked about the parallel payment and chained payment authorizations. They were very quick to respond, and basically just said..”Chained Payment has been enabled”. So yes, that was the problem for why the “Error ID: 550001. User is not allowed to perform this action” message was appearing.

I tried it now, after they enabled chained payments and seemed like it went through. I didn’t complete a transaction because I am using one of my vendor’s emails on a test product, just to see if I’ll be able to get to the PayPal payment screen, which I did.

…That is a relief…Hopefully this helps someone that experiences same Error issues.
Check to see what your app was approved for. I did send a form with both Parallel, and chained payment selected, but for some reason only had it approved for Parallel.

Sure Jamie, glad if I am able to help.
It took me a while to come to that, and it is a relatively simple “fix”.
