Heeeeeeeeeelp Cvv Code Error!

nykik · June 25, 2007

I used the contribution from sep 06 to add the cvv code for processing. Now receiving the following error. I asked for hep for 4 days with no responses. I need someone who has successfully installed the module to help me. I'm receiving the following error:

Warning: Missing argument 4 for validate() in /web/osc/includes/classes/cc_validation.php on line 16

Warning: Cannot modify header information - headers already sent by (output started at /web/osc/includes/classes/cc_validation.php:16) in /web/osc/includes/functions/general.php on line 29

(Please note that I did recall changing any information on the functions/general php.)

Here is my validation file per the recommendations. Please help me correct the problem. I'm new but eager to learn and make this work as I've had some customer complaints:

DAY 5, still trying to fix this. I found some cc_validation files, which fixed previous error, but now receiving NEW error after entering card number, expiration date and cvv code, received the following error.

[Credit Card Error

CVV code is 3 or 4 digits]

In the browser I see the following:

[checkout_payment.php?payment_error=cc&error=CVV+code+is+3+or+4+digits&cc_owner=Jane=Doe&cc_expires_month=04&cc_expires_year=10&osCsid=9023078f20dd1392a4c068584a4c0c82]

[Credit Card Error

CVV code is 3 or 4 digits]

Please help me! I haven't received any responses for this issue.

June 26, 2007

it suggests you have not install the mod correctly - the cvv value is not being passed to the new cc_validation.php file hence the error "Warning: Missing argument 4 for validate() in /web/osc/includes/classes/cc_validation.php on line 16" and the 4th argument being $cvv2.

re-download the contribution, carefully read the install instructions and see if you have missed any files or file edits

Tom

nykik · June 26, 2007

I'm doing exactly what you suggested. I no longer receive the argument error. I now see the follwing error in check_out payment.php

[Credit Card Error

CVV code is 3 or 4 digits]

In the browser I see the following:

[checkout_payment.php?payment_error=cc&error=CVV+code+is+3+or+4+digits&cc_owner=Jane=Doe&cc_expires_month=04&cc_expires_year=10&osCsid=9023078f20dd1392a4c068584a4c0c82]

I looked in this file, and the download and don't see instructions to add a code to this file. Do you have an idea on this?

If you are entering a 3 or 4 digit value for the cvv then this error probably means that the vlaue is not being passed correctly from checkout_payment.php to the payment module, so the module is reporting the error.

Which contrib are you using - post the link here

Tom

nykik · June 26, 2007

I'm using this contribution from PenguinMan98 from 7Sep 06'

Let me know what you think. Your help is appreciated beyond measure.

June 26, 2007

Looking at the code in the contrib I can't see any obvious problem.

Have you freshly re-uploaded the 2 files in the contribution to the correct places (i.e. catalog/includes/classes/cc_validation.php and catalog/includes/modules/payment/cc.php)?

Have you modified checkout_payment.php in any way for other contributions?

Which version of PHP are you using?

nykik · June 27, 2007

Yes! After I installed each file, I saved each change as I made them before going to next file. I can see 1 improvement, but the 3 or 4 digit error ist now showing, the argument 4 is missing is no longer showing.

I'm using version phpMyAdmin2.10.0.2

I did not do any changes to the checkout_payment.php because I did not see instructions to do so. I would think I would have add the code into this file, but did not. I copied it below:

[ require('includes/application_top.php');

// if the customer is not logged on, redirect them to the login page

if (!tep_session_is_registered('customer_id')) {

$navigation->set_snapshot();

tep_redirect(tep_href_link(FILENAME_LOGIN, '', 'SSL'));

}

// if there is nothing in the customers cart, redirect them to the shopping cart page

if ($cart->count_contents() < 1) {

tep_redirect(tep_href_link(FILENAME_SHOPPING_CART));

}

// if no shipping method has been selected, redirect the customer to the shipping method selection page

if (!tep_session_is_registered('shipping')) {

tep_redirect(tep_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL'));

}

// avoid hack attempts during the checkout procedure by checking the internal cartID

if (isset($cart->cartID) && tep_session_is_registered('cartID')) {

if ($cart->cartID != $cartID) {

tep_redirect(tep_href_link(FILENAME_CHECKOUT_SHIPPING, '', 'SSL'));

}

// Stock Check

if ( (STOCK_CHECK == 'true') && (STOCK_ALLOW_CHECKOUT != 'true') ) {

$products = $cart->get_products();

for ($i=0, $n=sizeof($products); $i<$n; $i++) {

if (tep_check_stock($products[$i]['id'], $products[$i]['quantity'])) {

tep_redirect(tep_href_link(FILENAME_SHOPPING_CART));

break;

}

// if no billing destination address was selected, use the customers own address as default

if (!tep_session_is_registered('billto')) {

tep_session_register('billto');

$billto = $customer_default_address_id;

} else {

// verify the selected billing address

$check_address_query = tep_db_query("select count(*) as total from " . TABLE_ADDRESS_BOOK . " where customers_id = '" . (int)$customer_id . "' and address_book_id = '" . (int)$billto . "'");

$check_address = tep_db_fetch_array($check_address_query);

if ($check_address['total'] != '1') {

$billto = $customer_default_address_id;

if (tep_session_is_registered('payment')) tep_session_unregister('payment');

}

require(DIR_WS_CLASSES . 'order.php');

$order = new order;
