Need to make CVV2 required field

Recommended Posts

I don't need anything fancy, just an easy fix would be appreciated. I am not much of a coder so this is very hard for me to figure out.

Greetings,

I installed this:

http://www.oscommerce.com/community/contri...all/search,cvv2

 

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.

Which cc validation class? I am not all that great at coding and havent worked much with the code so this is pretty new to me. Which files would I end up editing?

Thanks a ton for your reply satish

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?

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 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..

I am using ccv version 2, so my class cc_validation looks like this:

{

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);

 

Right after this I am adding

if ($ccv2)

{}

else

{return an error}

 

and I get a blank white screen if the customer does not enter a CCV and clicks continue

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.

Here is the latest edit I have done but still get blank screen

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 = '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';

} elseif (ereg('^5610[0-9]{12}$', $this->cc_number)) {

$this->cc_type = 'Australian BankCard';

} else {

return -1;

}

 

if (is_numeric($expiry_m) && ($expiry_m > 0) && ($expiry_m < 13)) {

$this->cc_expiry_month = $expiry_m;

} else {

return -2;

}

 

$current_year = date('Y');

$expiry_y = substr($current_year, 0, 2) . $expiry_y;

if (is_numeric($expiry_y) && ($expiry_y >= $current_year) && ($expiry_y <= ($current_year + 10))) {

$this->cc_expiry_year = $expiry_y;

} else {

return -3;

}

 

if ($expiry_y == $current_year) {

if ($expiry_m < date('n')) {

return -4;

}

}

 

if ( (strlen($cvv2) < 3) or (strlen($cvv2) > 4)) {

return -5;

}

 

return $this->is_valid();

}

 

if ($ccv2)

{}

else

{return an error}

 

function is_valid() {

$cardNumber = strrev($this->cc_number);

$numSum = 0;

 

for ($i=0; $i<strlen($cardNumber); $i++) {

$currentNum = substr($cardNumber, $i, 1);

I know this post is a little old, but I find the "helpful" posts to be very unhelpful. So here is how to make CVV a required field:

 

In your payment module in includes/modues/payment/ add these pieces of code where appropriate:

 

In the javascript validation section:

'	if (cc_checkcode == "" || cc_checkcode.length < "3" || cc_checkcode.length > "4") {' . "\n".
		 '	  error_message = error_message + "' . MODULE_PAYMENT_YOUR_PAYMENT_MODULE_TEXT_CVV_ERROR_CODE . '";' . "\n" .
		 '	  error = 1;' . "\n" .
		 '	}' . "\n" .

 

Where you see $selection = array add this:

array('title' => MODULE_PAYMENT_YOUR_PAYMENT_MODULE_TEXT_CREDIT_CARD_CHECKNUMBER,
					 'field' => tep_draw_input_field('your_payment_module_cc_checkcode', '', 'size="4" maxlength="4"') . ' <small>' . MODULE_PAYMENT_YOUR_PAYMENT_MODULE_TEXT_CREDIT_CARD_CHECKNUMBER_LOCATION . '</small>')),

 

Below this:

$this->cc_expiry_year = $cc_validation->cc_expiry_year;

add this:

$this->cc_checkcode = $cc_validation->cc_checkcode;

 

where you see this: $confirmation = array

insert this:

array('title' => MODULE_PAYMENT_YOUR_PAYMENT_MODULE_TEXT_CREDIT_CARD_CHECKNUMBER,
												'field' => $HTTP_POST_VARS['your_module_cc_checkcode']),

 

where you see this:

$process_button_string

insert this:

tep_draw_hidden_field('cc_checkcode', $HTTP_POST_VARS['your_module_cc_checkcode']) .

 

to pass the cvv code to the card processing company use something like this in amongst all the other informaton to be passed:

 

$cc_checkcode = iconv(CHARSET, 'UTF-8', $HTTP_POST_VARS['cc_checkcode']);

 

Then make sure that you have the TEXT defines from above in includes/languages/english/modules/payment/your_module.php

 

I won't be monitoring this thread, and won't be replying to posts on it - but this should help you out.
