Enhanced package quantity restriction enforcement by hiding the cart
quantity input field when restrictions are enabled. This prevents
customers from modifying quantities in the cart to bypass package
restrictions.
Changes:
- Added cart quantity input hiding for restricted products
- Implemented woocommerce_cart_item_quantity filter hook
- Created maybe_hide_cart_quantity_input() method in WC_TPP_Cart
- Fixed cart quantity bypass vulnerability
- Cart displays quantity as read-only text for restricted products
