What does "content-type" do in shoppingCart class?

[g_p_java]

Hello,

 

in file includes/classes/shopping_cart.php the shopping cart class has an attribute

named "content-type".

1. What does that attribute do??There is a method in the class named "get_content_type()",i assume that it returns the content_type in the basket, right??Also, this method is used in the following files: catalog/ext/modules/payment/paypal/express.php and express_uk.php, in catalog/includes/classes/order.php and in catalog/includes/classes/shopping_cart.php.

 

In other lines of the file includes/classes/shopping_cart.php, the values "mixed" and "physical" are assigned to the attribute content-type.

e.g.

$this->content_type = 'mixed';
$this->content_type = 'physical';

2. Also, is the attribute cartID ONLY created in includes/classes/shopping_cart.php??

 

thanks, in advance

content type determines whether an order is "mixed", "physical" or "virtual". An order with all Virtual products skip shipping.
