Update my custom theme cart to show correct product link

As default the links within cart should reflect the original shop where they pushed to the cart. In some cases a custom theme is not using the recommended WooCommerce template implementation which conclude to wrong url. Fortunate this is a small update, explained in the following lines.

Many themes use something like this to output the cart:

            global $woocommerce;
            $carts = array_reverse( $woocommerce->cart->get_cart() );
            foreach ( $carts as $cart_item_key => $values ) : ?>

                <?php $_product = $values['data'];
                    if ( $_product->exists() && $values['quantity'] > 0 ): ?>

                    <div class="product">

                        ... more code ...
                    </div>
                    <!--/product -->

                <?php endif; ?>
            <?php endforeach; ?>

This need a bit of update to include the switch_to_blog() and restore_current_blog() so add the 2 new lines:

            global $woocommerce;
            $carts = array_reverse( $woocommerce->cart->get_cart() );
            foreach ( $carts as $cart_item_key => $values ) : ?>
                <?php switch_to_blog($values['blog_id']); ?>
                <?php $_product = $values['data'];
                    if ( $_product->exists() && $values['quantity'] > 0 ): ?>

                    <div class="product">

                        ... more code ...
                    </div>
                    <!--/product -->

                <?php endif; ?>
                <?php restore_current_blog() ?>
            <?php endforeach; ?>

At this point the products within the cart, pushed on other shops will use the correct links back to original shop.
