Enables the credit card fields for Gravity Forms and provides a function to get the credit card details which are not available through the filter $form or $entry

Gravity Forms Get Credit Card Details

//Turn on our credit card field for admin and front end
add_action("gform_enable_credit_card_field", "enable_creditcard");
function enable_creditcard($is_enabled){
    return true;
}
//Email encoded card details when the form is submitted.
add_action('gform_after_submission', 'email_encoded_cc', 10, 2);
function email_encoded_cc($entry, $form) {
function get_creditcard_field($form){
        $fields = GFCommon::get_fields_by_type($form, array("creditcard"));
        return empty($fields) ? false : $fields[0];
    }
        $card_field = get_creditcard_field($form);
        $card_number = rgpost("input_{$card_field["id"]}_1");
        $expiration_date = rgpost("input_{$card_field["id"]}_2");
        $expire_month = $expiration_date[0];
        $expire_year = $expiration_date[1];
        $security_code = rgpost("input_{$card_field["id"]}_3");
        $card_name = rgpost("input_{$card_field["id"]}_5");
$cc_detail_string =  "CCName $card_name CCNum $card_number CCexp $expire_month-$expire_year CCV $security_code  " ;
//remember base 64 is not encryption - just encoding!
$encoded_cc_detail_string = base64_encode($cc_detail_string);
//send encoded cc details via email
$to = "[email protected]"; /*your email here*/
$subject = "For your eyes only";
$body = $cc_detail_string; /*or encoded string*/
$message = "Here are some cc details $body";
$from = "[email protected]";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
}

Thank you so much for this code! I spent hours trying to figure this out.
