Hiya -

 

This seems to be a continual problem with UK debit cards - my cc_validate file will not allow debit cards to be processed, and well frankly I just have no idea how to amend the file to add the debit card bin number ranges in.

 

The key part of cc_validate.php is currently:

 

if (ereg('^4[0-9]{12}([0-9]{3})?$', $this->cc_number)) {

$this->cc_type = 'Visa';

} elseif (ereg('^5[1-5][0-9]{14}$', $this->cc_number)) {

$this->cc_type = 'Master Card';

} elseif (ereg('^3(0[0-5]|[68][0-9])[0-9]{11}$', $this->cc_number)) {

$this->cc_type = 'Diners Club';

} elseif (ereg('^6011[0-9]{12}$', $this->cc_number)) {

$this->cc_type = 'Discover';

} elseif (ereg('^(3[0-9]{4}|2131|1800)[0-9]{11}$', $this->cc_number)) {

$this->cc_type = 'JCB';

} else {

return -1;

 

Does anyone have the relevant range codes for Delta/Electron/Maestro/Switch & Solo?

 

I have up to date bin ranges for the cards, but as I don't even understand the format of the coding (Barely a basic php newbie!) I just don't know how to start adding them in...

 

Can anyone help with the code or decipher the above card number format info so I could have a stab at it myself?

 

Thanks everso...!

Hi,

 

This is the code I use for one of my customers. I ripped it from a Zencart module and commented out the lines for the cards my customer didn't accept. Simply comment out the Return -1 and uncomment the card name. Just remember to backup first.

 

Hope it's ok for you.

 

Mark.

:blink: Still having problems with debit payment cards using optimal payments .... but different ones!

 

I think the problem is because the Optimal Payment module I am using does not collect an issue number which is found on some debit cards.

 

The relevant code in the optimal/firepay module is:

 

<?php

#

# Payment Module SureFire Commerce via FirePay for osCommerce (
)

# Developed by mike wOZniewski,

# If you find bugs, have questions, please email mike@OZmediaSolutions.com

#

# API information, white papers, protocol info can be found at

#

# IMPORTANT NOTES FOR THIS VERSION:

# - Since FirePay does not return a message in the header, this module uses CURL to post and receive a response. This MUST be installed on your server if this module is to work (found at
.

# - You cannot use your regular account, username, and password if you are using the TEST mode; you must contact SureFire and request a test account.

# - Currencies are NOT sent to SureFire. Your SureFire account has a specific default currency, and any order totals should be in that currency.

#

# THINGS STILL TO DO:

# - Add currency conversion for order total to convert it to your SureFire default currency.

# - Modify the cc_validation.php class to accept FirePay Payments

#

So what I ned to do is add an extra field to capture an issue number and start date if present (so not required fields).... I think!

 

Does anyone have any idea where to start? I have discussed this with the payment processor who told me it would be a simple thing for anyone with php knowledge... thanks... helpful... not!

 

...thank you ....
