Fixed critical plugin activation error that was preventing the plugin from
being activated on WordPress 6.9.x and WooCommerce 10.x.
The issue was introduced in v1.1.3 when admin classes were still being
instantiated immediately at file include time, before WooCommerce was loaded.
While v1.1.6 fixed this for Frontend and Cart classes, the Admin and
Product Meta classes were missed.
Critical Fix:
- Removed immediate instantiation from WC_TPP_Admin class
- Removed immediate instantiation from WC_TPP_Product_Meta class
- Both classes now instantiated via woocommerce_loaded hook
- Ensures all WooCommerce hooks are available before registration
Technical Changes:
- Removed "new WC_TPP_Admin();" from class-wc-tpp-admin.php
- Removed "new WC_TPP_Product_Meta();" from class-wc-tpp-product-meta.php
- Added both classes to init_classes() method in main plugin file
- All four main classes now follow consistent initialization pattern
Impact:
- Plugin now activates correctly on all WordPress/WooCommerce versions
- Resolves fatal errors during plugin activation
- Last working version was v1.1.2, now fixed in v1.1.8
Updated Files:
- includes/class-wc-tpp-admin.php (removed auto-instantiation)
- includes/class-wc-tpp-product-meta.php (removed auto-instantiation)
- wc-tier-and-package-prices.php (version 1.1.8, init_classes updated)
- composer.json (version 1.1.8)
- CHANGELOG.md (v1.1.8 section added)

Fixed critical bug that prevented plugin activation in v1.1.3, v1.1.4, and v1.1.5.
Root Cause:
- WC_TPP_Cart and WC_TPP_Frontend classes were instantiated immediately when
their files were loaded (via `new ClassName();` at bottom of files)
- This happened BEFORE WooCommerce was fully loaded
- Hook registration attempted to access WooCommerce functions before they existed
- Result: Fatal error during plugin activation
Solution:
- Removed immediate instantiation from class-wc-tpp-cart.php (line 251)
- Removed immediate instantiation from class-wc-tpp-frontend.php (line 186)
- Added init_classes() method to main plugin class
- Classes now instantiated via woocommerce_loaded hook
- Ensures WooCommerce is fully initialized before any hooks are registered
Changes:
- includes/class-wc-tpp-cart.php - Removed `new WC_TPP_Cart();`
- includes/class-wc-tpp-frontend.php - Removed `new WC_TPP_Frontend();`
- wc-tier-and-package-prices.php - Added init_classes() and woocommerce_loaded hook
- CHANGELOG.md - Added v1.1.6 section
- composer.json - Version 1.1.6
- All translation files updated to 1.1.6
- All .mo files recompiled
This fix ensures proper WordPress plugin lifecycle:
1. Plugin file loaded
2. Classes defined (but not instantiated)
3. WooCommerce loads
4. woocommerce_loaded hook fires
5. Classes instantiated with full WooCommerce availability

CRITICAL FIX: Resolved fatal error that prevented plugin activation in
versions 1.1.3 and 1.1.4. The add_cart_quantity_css() method was attempting
to access WooCommerce cart object during wp_head action, causing failures
when WooCommerce wasn't fully initialized or on admin pages.
Fixes:
- Plugin activation error in v1.1.3 and v1.1.4
- Fatal error when WooCommerce cart object not available
- Frontend errors on admin pages
- Issues during plugin initialization
Technical Changes:
- Added function_exists('WC') check before accessing WooCommerce
- Added is_admin() check to prevent CSS injection on admin pages
- Enhanced add_cart_quantity_css() with proper guards
- Line 191: if (!function_exists('WC') || !WC()->cart || is_admin())
Root Cause:
The add_cart_quantity_css() method (added in v1.1.3) hooks into wp_head
but didn't properly check if WooCommerce cart was available, causing
errors during plugin activation and on admin pages.
Updated Files:
- includes/class-wc-tpp-cart.php (enhanced error checking)
- wc-tier-and-package-prices.php (version 1.1.5)
- composer.json (version 1.1.5)
- CHANGELOG.md (v1.1.5 section)
- All translation files (.pot, .po, .mo) updated to version 1.1.5

restricted products directly from shop/category pages.
Changes:

- 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)

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
