How can I keep customers from using american express, my customer doesnt accept that card, only visa and mastercard?

 

in catalog/includes/classes/cc_validation.php look for:

 

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;

}

 

 

and replace with:

 

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';

} else {

return -1;

}

Thank you very much!

Except that code will block any Maestro cards, which are issued by MasterCard.

 

Whether this is a problem or not will depend on whether Maestro cards are issued in your country and whether you are allowed to accept them. If you are in the UK it would be a major issue - they account for about 10% of our sales.

 

If MasterCard or Visa issue any cards that fail those checks, you will be rejecting them.

 

I allow all valid credit card numbers through the validation. Sometimes people will pay by American Express which I can't accept, but the hastle from these orders is better than losing orders due to a valid card number being rejected.
