problems with cybersource payment module

[jobber99]

so in tpl_checkout_payment_default.php, there's this line:

<div class="messageStackError"><?php echo zen_output_string_protected($_GET['credit_class_error']); ?></div>


it seems like when i have longer errors, this craps out.
i.e.:
http://MyDomain/index.php?main_page=...er+credit+card

errors out (i.e. blank page) but if you trim that to:

http://MyDomain/index.php?main_page=...ing+with++was+

it's fine. is there something with zen_output_string_protected that would choke on longer strings?

The problem is not with zen_output_string_protected.

Your problem is that you're using a payment module written for an old version of Zen Cart, and it's passing very long error messages via the URL instead of via the $messageStack.

Rewrite your module to use current methods and you'll be fine.

thanks. we are using cybersource, and followed this guide:

http://www.zen-cart.com/forum/showthread.php?t=55738

is there a newer guide to implementing cybersource?

[jobber99]

also, can i get an example of how to implement the $messagestack->add_session?
i tried looking around and attempted this:

$messagestack->add_session('checkout_payment', 'hello world','error');

but this gives me a 500 server error

Here's an example of it from one of the authorize.net modules:

    global $messageStack;
    $messageStack->add_session('checkout_payment', MODULE_PAYMENT_AUTHORIZENET_TEXT_ERROR_MESSAGE, 'error');
    zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL', true, false));
