Express Checkout payment module

[philip937]

Ok leave it with me and I'll try and do more testing, the first issue is becoming less of an issue now so might have just been a glitch and coincidence I had two in a row.

Is there a way you can manually force a customers cart to process in the event of such an occurrence? I.e if you know the customer has paid but the order doesn't create? Would be great to have a list of unapproved orders and the ability to manually approve?

Please stay on this thread and I'll post back when I have more info, cheers Doc

Dr Byte, appologised for the delay, I'm actually away this week so will be doing testing of the express checkout at the weekend.
I have just had another order through payments standard that has had the same problem where it isn't creating the order. Any ideas what could be causing a session value not to be stored against the order which causes the details not to be found?

[DrByte]

Problems with Standard are usually currency or price mismatches, and would be shown in the logs if logging is enabled.

The problem I have with standard is the error I posted above where it's not finding a matching session id. I was wondering if there is anything that would cause that to happen?

[DrByte]

Well, then either you've got your site seriously broken by altering all manner of core code, or those particular log messages are coming from PayPal/eBay transactions which originated from outside your store.

Odd, well only started to happen since I switched to PayPal standard so hopefully going back to express should fix it??

[DrByte]

Hopefully.

Doc,

Just had another order on the payments standard not create the order, i've just looked at the logs and say the following at the bottom:


| mc_currency = GBP
| submitted_currency = GBP
| order_currency = GBP
| mc_gross = 36.37
| converted_amount = 36.36
| order_amount = 36.3632

Dec 05 2012 16:47 -- IPN NOTICE :: Failed because of currency mismatch.


how can I fix this? so that when i resend the IPN the order will go through?

Thanks

Phil

I just resent the IPN and the error now says similar to the other logs I saw:

Dec 05 2012 17:20 -- NOTICE: IPN Processing Aborted due to missing matching transaction data, as per earlier debug message. Perhaps this transaction was already entered via PDT? Thus there is no need to process this incoming IPN notification.

So I guess the first error and reason orders are not created is due to currency mis match, and the second do do with the fact that the IPN resending is not finding the order info? is the order info being deleted when the first process runs? and hence the second message?

For now I have found this two liner fix for the currency mis-match but I assume it only works when an order is created from scratch?

  //  $this->totalsum = $order->info['total'];
    $my_currency = select_pp_currency();
    $this->totalsum = $order->info['total'] = zen_round($order->info['total'], $currencies->get_decimal_places($my_currency)); 

I saw in the same thread this was fixed in v1.5, however I don't have time to upgrade at present, is there a better way to do a fix for this or is the two liner above the only way on 1.3.9h ?

I'm guessing that discounts ect I have set are rounding incorrectly which is what is causing the problem?

Thanks Phil

[philip937]

with the two liner fix how is it working? I have just simulated the order (without placing it) with this altered code.

The shopping cart total shows as
£36.36

and when at paypal is:
£36.37

this is the same as before i changed the code, does this mean its not working or is the modified rounding done when the data is sent back to confirm the order?
