Hello,

We are having problems with Offline Credit Card Checkout on the payment screen which is returning an error....

"Unfortunately, we are unable to accept your transaction. There may be a problem with the payment information you entered, or our online processor may be experiencing technical difficulties at the present time. You can attempt to process your order again, or contact us to discuss other payment options."

This is only happening with this payment type yet Paypal, Google Checkout, and all check, money order, etc seem unaffected.

I ran the debug and there is much information just for this one event. I have no idea what I'm looking at.

Any Suggestions?

Thanks

I'm not sure if this helps but here's the display code....

I think we figured out that the customer was entering the credit card number with spaces like XXXX XXXX XXXX XXXX causing the error and we weren't using a mod10 card number to test it. We wound up modifying the field description

from:

Code:

'Enter your credit card number.'));

to:

Code:

'Enter your credit card number without spaces or dashes.'));

Hopefully this will make it clear enough to the purchaser from here on out.

If this is what is happening CCP should remove all non numeric characters to avoid any errors.

Dave · 03-20-2012 16:19:51

CCP does no checking or modifying of data entered into any fields on any forms (though for a CC field it does a simple mod10 as a basic sanity check). Cleaning up the CC field has been asked for since about day 2 of the V6 release.

polarize · 03-20-2012 18:02:04

I thought there was also something in the code to parse out spaces and dashes in version 7. The mod10 check is good though. Perhaps a good idea for the customer is if the field will change to red or something to alert the customer to what the error is as opposed to such a generalization error upon submit.

Nope.

cyberws · 03-21-2012 09:04:50

CCP should really except it either way and just strip out ALL none numeric characters using preg_replace.

Below is an example as the field name isn't right. But it does illustrate how easy it can be done with this code and proper variable name placed into the correct file.

Code:

$creditcardnum=preg_replace('/[^0-9]/','',$creditcardnum);

In private/ecom/ECOM_Olp\etc\offline.php

Change

$cgi['ccnum'] = $this->CORE_Crypt->encrypt($cgi['ccnum']);

to

$cgi['ccnum'] = preg_replace('/[^0-9]/','',$this->CORE_Crypt->encrypt($cgi['ccnum']));

I haven't tested it, but that should work.

cyberws · 03-21-2012 10:56:32

The code above will run the encryption but then preg_replace will remove any none numeric characters and thus it will fail on decrypt.

So it should first remove all non numeric characters then the encrypt field so if non numeric characters are generated they won't be removed.

Code:

$cgi['ccnum']  = preg_replace('/[^0-9]/','',$cgi['ccnum']);
$cgi['ccnum']  = $this->CORE_Crypt->encrypt($cgi['ccnum']);
