Hi to everyone.
I would like to know how I can restrict the use of "Add to cart" button to only registered user, in order I can be sure that non-member users could not perform any shopping without login or register.
I am thinking to add an "IF" check in the function that controls the "Add to cart" button, something like this:
if is_user_logged_in {do the normal routine}
else {redirect to login-register page}
but I couldn't find where in eShop plugin is stored this button action.
Could you please give me some advice?
