* 2 More Hooks
* But there also 2 more hooks which are very similar – woocommerce_before_add_to_cart_form and woocommerce_after_add_to_cart_form.
* The hook woocommerce_before_add_to_cart_form will be fired a little bit earlier that woocommerce_before_add_to_cart_button, before <form> tag.
* The hook woocommerce_after_add_to_cart_form will be fired a little bit later than woocommerce_after_add_to_cart_button, after the closing </form> tag.

* $product
***** It is a product object – it could be WC_Product_Simple or WC_Product_Variable or even WC_Product_Subscription if you are using WooCommerce Subscriptions plugin. You can obtain $product->id from these objects for example.
* $args
***** It just contains button attributes like quantity, class names etc
