Blocking Discover and Amex

[ziggy13]

I need to block Amex and Discover credit cards because my company does not accept them. I have put up notices and images on my website showing that we only take Visa & MC but people still put Discover cards in. I want to completely block people from being able to enter a Visa or Discover card on my site. What is the best way to do this?

open /catalog/includes/classes/cc_validation.php and remove these two if statements:

 

elseif (ereg('^6011[0-9]{12}$', $this->cc_number)) {

$this->cc_type = 'Discover';

}

 

and

 

elseif (ereg('^3[47][0-9]{13}$', $this->cc_number)) {

$this->cc_type = 'American Express';

}
