Disabling MasterCard doesn't work with own payment module

[mscro]

We have our own payment module (created by a 3rd party) for processing creditcards, which is working fine, but now we don't want to process MasterCard transactions through that account.

I tested it with "Credit Card Enable Status - MasterCard - Value 0" at Configuration -> Credit Cards, but this doesn't work. I still can go to the "step 3 of 3" checkout procdure without getting a error.

Is that possible because there are some things missing in the payment module? Is there another way how we can disable MasterCard transactions?

Thanks!

We are using:
Zen Cart 1.3.0.1
Database Patch Level: 1.3.0.1

We tried to update to the latest zen-cart version, but that doesn't work. Errors at the payment.php

Any solution to disable mastercard with this version?

Is there any manual for creating your own payment module?

I think you need to get with the developer that created your payment module. It sounds as if there may be hardcoded values that are causing problems.

He don't work any more

Any way I try to find some solution to put java script on page checkout_payment.php Step 2 of 3 to disable master card, but i'm not sure where i need to put this script.

Maybe someone know some tutorials about payment scripts??
In short time we also need to change our payment system, and with new system we will try to make with latest version of zen-cart.

Thanks!

I found this function



$ccnValidation = "var nrcField = document.checkout_payment.number.value;\n" .
"if ( nrcField.length < " . CC_NUMBER_MIN_LENGTH . ") {\n" .
" error_message = error_message + 'Invalid credit card number.\\n';\n" .
" error = 1;\n" .
"}\n";

this check only for lenght of min. number, can this check if is there master card first number :5 ?


here is complete function:





function javascript_validation()
{
$ccvValidation = "var ccvField = document.checkout_payment.cvc.value;\n" .
"if ( ccvField.length < " . CC_CVV_MIN_LENGTH . ") {\n" .
" error_message = error_message + 'Invalid CCV entered.\\n';\n" .
" error = 1;\n" .
"}\n";
$zipValidation = "var zipField = document.checkout_payment.zip.value;\n" .
"if ( zipField.length < 4) {\n" .
" error_message = error_message + 'Invalid ZIP code entered.\\n';\n" .
" error = 1;\n" .
"}\n";
$addValidation = "var addField = document.checkout_payment.address.value;\n" .
"if ( addField.length < 3) {\n" .
" error_message = error_message + 'Invalid address entered.\\n';\n" .
" error = 1;\n" .
"}\n";
$nameValidation = "var fnameField = document.checkout_payment.firstname.value;\n" .
"var lnameField = document.checkout_payment.lastname.value;\n" .
"var tName = fnameField + ' ' + lnameField;\n" .
"if ( tName.length < " . CC_OWNER_MIN_LENGTH . " ) {\n" .
" error_message = error_message + 'Input name length to low!\\n';\n" .
" error = 1;\n" .
"}\n";
$ccnValidation = "var nrcField = document.checkout_payment.number.value;\n" .
"if ( nrcField.length < " . CC_NUMBER_MIN_LENGTH . ") {\n" .
" error_message = error_message + 'Invalid credit card number.\\n';\n" .
" error = 1;\n" .
"}\n";
$valChecks = $nameValidation . $addValidation . $zipValidation . $ccvValidation . $ccnValidation;
return($valChecks);
}
