magdev 4ece4dd69e Release version 1.1.2 - Catalog button modification 
Enhanced package quantity restriction enforcement by replacing "Add to Cart"

restricted products directly from shop/category pages.

Changes:
- Added catalog button modification for restricted products
- Implemented "View Options" button with eye icon styling
- Created has_quantity_restriction() helper method
- Extended CSS loading to all WooCommerce pages
- Added modify_catalog_add_to_cart_button() filter method
- Updated translations with 2 new strings (en_US, de_DE, de_CH_informal)

Add to Cart Validation (v1.1.0)

Settings

Use Cases

Scenario 1: Bulk-Only Sales

Enable restriction globally to sell products only in bulk quantities.

Example:

  • Package 1: 100 units at $500
  • Package 2: 250 units at $1,100
  • Package 3: 500 units at $2,000

Customers can only purchase these exact quantities on both product page and in cart.

Create fixed sample packs with no custom quantities.

Example:

Quantity cannot be changed in cart - customers must return to product page to select a different package.
