List of Common Classes used in Classic Commerce
The main class is woocommerce which is available globally via the $woocommerce variable. This handles the main functions of Classic Commerce and initializes other classes, stores site-wide variables, and handles error/success messages.
The woocommerce class initializes the following classes when constructed:
- WC_Query – stored in
$woocommerce->query - WC_Customer – stored in
$woocommerce->customer - WC_Shipping – stored in
$woocommerce->shipping - WC_Payment_Gateways – stored in
$woocommerce->payment_gateways - WC_Countries – stored in
$woocommerce->countries
Other classes are auto-loaded on demand.
WC_Product
Classic Commerce has several product classes responsible for loading and outputting product data. This can be loaded through PHP using:
$product = wc_get_product( $post->ID );
In the loop this is not always necessary since calling the_post() will automatically populate the global $product variable if the post is a product.
WC_Customer
The customer class allows you to get data about the current customer, for example:
global $woocommerce;
$customer_country = $woocommerce->customer->get_country();
WC_Cart
The cart class loads and stores the users cart data in a session. For example, to get the cart subtotal you could use:
global $woocommerce;
$cart_subtotal = $woocommerce->cart->get_cart_subtotal();
