[Plugin: WooCommerce] Buy Now or Auto-Redirect from "Add to Cart"

I did find the option “redirect to Cart page” after adding to cart. But for the Cart widget, how do I set it to only display when there are items in the cart?

Thanks!

Not sure about the cart widget but you can listen for the javascript event: added_to_cart or you could hook on to the filter
add_to_cart_redirect.

So if you wanted to do something after you added something to the cart you can do:

jQuery(document).on('added_to_cart', function(){
    //... do something
});
