Payment module porting from oscommerce problem

[filippo]

Hello!
I'm having a problem with ported oscommerce module. I made some changes and everything was fine, but then an error occured.

Here's code:

// if there is nothing in the customers cart, redirect them to the shopping cart page
  if ($cart->count_contents() < 1) {
    zen_redirect(zen_href_link(FILENAME_SHOPPING_CART));
  }

After last step in checkout I get blank page and debug log says:

[11-May-2009 14:56:06] PHP Fatal error:  Call to a member function count_contents() on a non-object in C:\wamp\www\mariola\zencart\ext\modules\payment\platnosci\checkout_platnosci.php on line 30

I am newbie with this stuff so maybe someone know how to resolve this problem.

Function count_contents() is method of shoppingCart class.

$cart should be $_SESSION['cart'] in Zen Cart v1.x
