add to cart with subscription option or update cart item with subscription option in custom page

[stevechoi]

Hi. We have Woocommerce variable product and bundle product, and want to add these products to cart with 'subscribe all the thing'`s subscription option like '2_weeks' or '3_weeks' in our custom page but I cannot find how to do that.

Is there a proper way?

I tried to do following methods.

1. $cart_item_key = WC()->cart->add_to_cart(11121, 1, 11151);
   => Item is inserted in cart. (is there way to set subscription option in this add to cart step?)

2. WC()->cart->cart_contents[ $cart_item_key ][ 'wcsatt_data' ][ 'active_subscription_scheme' ] = '5_week';

=> item's subscription option in cart not changed.

Thanks.

The approach seems right, but is 5_week a valid key?
