American Express Card Invalid Number

[Guest cdupuis]

I had a problem where people could not pay using an American Express card.

In case any other person has it here is the solution that was provided right away by Cubecart:

================Beginning=================

Please can you open classes/validate/validateCart.php

Find line: 48

$americanExpress = "^3[47][0-9]{13}$";

Replace with:

$americanExpress = "((^3[47])|(^3[37]))((\d{11}$)|(\d{13}$))";

That allows the card length to be 13 or 15 digits long starting 47 or 37.

=============== End ======================

Take care

$americanExpress = "((^3[47])|(^3[37]))((\d{11}$)|(\d{13}$))";

I haven't been able to get this to work... has anyone else run into this and made the AMEX validation work?

Help!

[Guest akumar]

is this still the same solution?

The new string in CC4.3 classes/validate/validateCart.php is:

'AMERICAN EXPRESS' => '#^[34|37|47]([0-9]{14}|[0-9]{13}|[0-9]{12})$#',

I just had a customer that had problems with her AmEx card on an order but was able to place the order with a different card. Anyone else having trouble with American Express cards using PayPal Pro via Alternative Checkout?
