cc.php error on checkout confirmation

[sackling]

I am getting this error at the top of the page at checkout confirmation:

 

Warning: str_repeat() [function.str-repeat]: Second argument has to be greater than or equal to 0 in /home1/mysite/public_html/includes/modules/payment/cc.php on line 137

 

This is what is on line 137:

 

  'field' => substr($this->cc_card_number, 0, 4) . str_repeat('X', (strlen($this->cc_card_number) - 8)) . substr($this->cc_card_number, -4)),

 

Any advice on what I can do to fix this?

actually just realized it is not "taking" the entered credit card number. and the field is left blank on confirmation.

 

This is now a pretty big problem!

You don't use the built-in credit card processing function -- it's not secure, and should be removed from osC. Use one of the add-ons or payment-gateway-supplied processors.

If your site processes or stores CC info you'd better be PCI Compliant ( <= it's a link, click it to read more).

 

If you violate the PCI mandates and are caught fines can run in the hundreds of thousands of dollars and you can be banned from getting a merchant account for life...
