Splitting Middle CC Digits.

[RosscoB]

Can anyone just point me into the right direction....

I need to know if it's possible to split the middle CC number sent by email into 2 parts... so instead of looking like this:

xxxxxxxx

it looks like this:

xxxx xxxx

Thanks
Ross.

Hi,

I commented on another thread on this topic.

Im not sure if I misunderstood your answer or you misunderstood what I was asking.

I don't want the email to be sent to 2 different addresses, nor do i want the ENTIRE CC number split.

What I am asking, is that when you receive the email msg with the middle digits, the middle digits look like this:

56781234

What I was wondering, if the email msg can be formatted so that the middle CC digits appear like this:

5678 1234 (a gap between the block of 4 numbers!).

This is just cosmetic change, so there shouldnt be any security risk, this is why I am asking.

Thanks
Ross.

It is customary - on practically all webshop systems - for card numbers to be entered by customers WITHOUT gaps - so this is the data that is captured. You may be able to cobble some javascript that splits this after 4 digits, but I'm no expert in that field. Connor Kerr (CEON) may have some advice here as he has built a good offline c-card module.

You could do some custom coding and edit your /includes/modules/payment/cc.php file to add a space before the email is sent.

Hi,
Thanks for pointing me in the right direction.
I found this bit of code in the cc.php file...

$this->cc_middle = substr($_POST['cc_number'], 4, ($len-8));

I presume this is what gets the middle 8 digits.
I don't know much about javascript (i'm a vb person! lol)...but im thinking something like this should do the trick...

$this->cc_middle = substr($_POST['cc_number'], 4, ($len-4)) + " " + substr($_POST['cc_number'], 8, ($len-4));

Am I close? Can anyone help me out with the syntax if I don't have it right?

Thanks
Rossco.

No, don't touch that part of the code or you'll have security issues.

A few lines later, you'll see this:

    $message = sprintf(MODULE_PAYMENT_CC_TEXT_MIDDLE_DIGITS_MESSAGE, $insert_id, $this->cc_middle);

change it to this:

    $message = sprintf(MODULE_PAYMENT_CC_TEXT_MIDDLE_DIGITS_MESSAGE, $insert_id, substr($this->cc_middle, 0, 4) . ' ' . substr($this->cc_middle, -4));
