Credit Card with CVV2

Well I finally got it working after a few problems. But I need to know how I can make that field required so that everyone that uses a credit card will have to input that?
Anyhelp would be great. Thank you.

in the cc validation class check for CVV and if blank then return an error.
Also in the check box when the user fill placea red *** showing that it is compulsry.

Have you found out the solution? What files do we need to change to make the CVV2 entry a MUST filed for customers to fill ?

Also how do we setup a link next to the CVV to explain what is CVV?

I installed this mod ... a version after the "fix for the database" but mine does not write the cvv to the database as far as I can tell. When I go into admin the CVV is blank. Was this not implimented in the newer version? I'm having a hard time finding the differences between the two..

In includes/classes/cc_validation.php
function validate($number, $expiry_m, $expiry_y) change to function validate($number, $expiry_m, $expiry_y,$ccv) .
Pass $ccv additionally to this function.

if ($ccv)
{}
else
{return an error}

I am having the same problem-when go into admin the CVV is blank.

The program is writing the CCV to teh database because I can see it in the database, but I do not see it in admin.

I got this contrib to work properly, but I need it to make CCV field have red asterisk and make it a required field. Anybody know how to do this? I can't get this part to work right.

class cc_validation {
var $cc_type, $cc_number, $cc_expiry_month, $cc_expiry_year, $cc_cvv2;

function validate($number, $expiry_m, $expiry_y, $cvv2) {
$this->cc_number = ereg_replace('[^0-9]', '', $number);

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)) {
$this->cc_type = 'Master Card';
} elseif (ereg('^3[47][0-9]{13}$', $this->cc_number)) {
$this->cc_type = 'American Express';
} elseif (ereg('^3(0[0-5]|[68][0-9])[0-9]{11}$', $this->cc_number)) {

$this->cc_type = 'Australian BankCard';
} else {
return -1;

$this->cc_expiry_month = $expiry_m;
} else {
return -2;
}

$expiry_y = substr($current_year, 0, 2) . $expiry_y;
if (is_numeric($expiry_y) && ($expiry_y >= $current_year) && ($expiry_y <= ($current_year + 10))) {

} else {
return -3;
}
