## [List of Classes in WooCommerce](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-1)
|
||
|
||
For a list of Classes in WooCommerce, please see the [WooCommerce Code Reference](https://woocommerce.github.io/code-reference/packages/WooCommerce-Classes.html).
|
||
|
||
## [Common Classes](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-2)
|
||
|
||
### [WooCommerce](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-3)
|
||
|
||
The main class is `woocommerce` which is available globally via the `$woocommerce` variable. This handles the main functions of WooCommerce and init’s other classes, stores site-wide variables, and handles error/success messages. The woocommerce class initializes the following classes when constructed:
|
||
|
||
- `WC_Query` – stored in `$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.
|
||
|
||
View the [WooCommerce Class Code Reference](https://woocommerce.github.io/code-reference/classes/WooCommerce.html) for a full list of methods contained in this class.
|
||
|
||
### [WC_Product](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-4)
|
||
|
||
WooCommerce 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](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-5)
|
||
|
||
The customer class allows you to get data about the current customer, for example:
|
||
|
||
```php
|
||
global $woocommerce;
|
||
$customer_country = $woocommerce->customer->get_country();
|
||
```
|
||
|
||
View the [WC_Customer Code Reference](https://woocommerce.github.io/code-reference/classes/WC-Customer.html) for a full list of methods contained in this class.
|
||
|
||
### [WC_Cart](https://github.com/woocommerce/woocommerce/blob/trunk/docs/extension-development/class-reference#section-6)
|
||
|
||
The cart class loads and stores the users cart data in a session. For example, to get the cart subtotal you could use:
|
||
|
||
```php
|
||
global $woocommerce;
|
||
$cart_subtotal = $woocommerce->cart->get_cart_subtotal();
|
||
```
|
