I was getting an error telling me the Credit Card Expiration Year was incorrect when I tried to process credit cards. I did a little more research and found linkpoint needs the years to be in 2 digits instead of 4 digits.
In the linkpoint module there is a line that is supposed to truncate the year down to 2 digits:
$xml .="<cardexpyear>" . date('y', $order->payment_details['cc_exp_year']) . "</cardexpyear> ";This wasn't working for me so I removed that line and replaced it with:
$cardexpyr = substr($order->payment_details['cc_exp_year'], 2, 2);
$xml .="<cardexpyear>" . $cardexpyr . "</cardexpyear> ";As of 10/8/2007 this module appears to be fully functioning for me.
