title: woocommerce how to get $cart_item_key for a single product
body: <p>I'm implementing a Remove Item button next to the add to cart button however I have a problem getting the variable $cart_item_key for a single product. I have the global variables $woocommerce and $product but the only way  $cart_item_key  is used is a foreach which doesn't  help me at all as I need my code to be added in add-to-cart.php.</p>
