I have the same question:
How I can get quantity of product and show in another part of my site?
For ex. in some small box - on the left - like in sidebar (with .hover() function)
On the left I have got fixed sidebar with menu etc. and at the bottom I'd like to show "my" orders. Exactly => quantity of products.
Plugins have got some widget called WooCommerce Cart but they are showing everything. I need only quantity of products.
Is this possible with "cart class" or something like that?
