Hi Q,

Our shop uses 1.4.9.1 and I just updated the two files u mentioned in the post above.
Unfortunately the paypal link doesnt work at all now. It says that the link has wrongly formatted value in it.

Any ideas? Reason for us to update was that we have the issue with coupons not getting properly applied by paypal if the discount is bigger or equal to the subtotal.

Cheers,

Newbie

Should you not update your first post and change/add this to it?
In your first post it still says that 1.4.9.x user should not use the files in the download.

Ok I've updated Paypal Standard in the first post. This version is NEWER than the one in v1.4.9.3.
I found and fixed quite a few problems with currency conversion and discount checking that should hopefully fix a lot of problems people were having.


NOTE ABOUT MULTIPLE CURRENCIES
OpenCart and Paypal get their exchange rates from different sources at different times of the day. This means that when customers are using a currency that is not your default currency, the exchange rate for the Total could vary slightly from what Paypal shows. There is no easy fix for this as paypal doesn't allow passing the exchange rate value currently used. This is just a fact of life that has always existed.

One Alternative for this if it really bothers you, is to force paypal to always use your default currency. So if the customer sees GBP on the checkout page, when they goto Paypal they will see USD (or whatever your default is).

Another alternative is to forcibly switch the customer's selected currency on the site to your default currency when reaching the checkout/confirm page. This means they see the final page in your default currency instead of their currency.

And finally, and perhaps the best, would be to just include a simple javascript popup when clicking the checkout button that the price on paypal may vary slightly due to exchange rates.

Yes it can be used in production
No it will not reset settings
just overwrite the files and double check all settings in the admin paypal configuration area

Due to new paypal india policy - https://www.thepaypalblog.com/2011/01/a ... for-india/
Perhaps best if you move to a less silly country :) USA has $2000 limit

That is pretty bad tbh. Forcing you to take money out of your PP account within 7 days and not allowed to buy goods with it. I know exactly why they are doing it but it's a bit tedious if you ask me. paypal may as well just automatically send the money straight to your bank account (although they wont so that they can get interest on your money sitting there of course). I'm just wondering is this for paypal standard only in India or PP pro as well (do they have PP pro in India?)

You won't be able to split the payment into two and only require the customer to check out once, it just won't happen

It will definitely hinder things yes for people purchasing from/selling to India. I'm not sure exactly how most people would feel about having to do two checkouts to complete a transaction, not to mention the logistics of it

This is a separate "feature" that needs to be addressed.. this has always been there and happens when the payer has a & or other "strange" characters in their name. It would have happened with the previous version too.. but you still need the fixes in this version.

Ipn is getting the mismatch. You likely have PDT enabled so it is recovering itself and completing

Ok I figured out the problem with the handling fee when discount is greater than subtotal and fixed it.

Another issue that paypal can't process 0.00. So when the discount results in the cart total = 0.00, paypal will simply ignore the discount completely because they are stupid like that.

So I've added a little fix to the ajax confirm function that gets called when clicking submit. If the total = 0.00, it just completes the order and bypasses the paypal login.

Updated the zip in the first post here:

be sure to update all catalog files as a few of them have changes

Im Currently running paypal 1.4.2 and am finding it REALLY slow to respond between checkout/confirm page and paypal. (40 secconds+)

Would upgrading fix this?

I intend to upgrade anyhow but i want to know if this could be an issue that wont be resolved by upgrading.

I had my first scammer today buy a bunch of my extensions using a stolen PayPal account. Does the newest version of the paypal module check whether the OpenCart e-mail matches the PayPal e-mail? I know it says this:
Many additional validation steps to cut down on scammers (price match, email match, referrer, etc)
but I just wanted to check if that's what "email match" refers to.

Anyone have any other tips on preventing these things from happening?

No there is no check that their account email = paypal email as that isn't always the case. Email match means that in case they catch and alter the message and change the seller email to their own account and then fake the ipn back to you. Not likely but just in case.

I am looking into adding an email verification option like daniel did to the extension store. Then you could choose to enable that extra security.
