# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [1.1.12] - 2025-12-31 ### Fixed - **CRITICAL**: Variable product variations still not appearing in product selector after v1.1.11 release - Changed variation retrieval method from `get_available_variations()` to `get_children()` for more reliable variation ID retrieval - `get_available_variations()` returns complex data arrays which may not work in all contexts - `get_children()` returns simple array of variation IDs directly, ensuring consistent results ### Technical - Modified file: includes/Product_Type.php (lines 171-184) - Changed from `$product->get_available_variations()` to `$product->get_children()` - More direct and reliable method for retrieving variation IDs - Each variation ID passed to `wc_get_product()` for full product object - Maintains all stock and purchasability checks from v1.1.11 ### Notes - This is a patch release fixing the variable product support introduced in v1.1.11 - User reported "nope, still no product selectable" after v1.1.11 - Root cause: `get_available_variations()` returns variation data arrays instead of clean IDs - `get_children()` is the standard WooCommerce method for retrieving variation IDs - All translation files remain at 100% completion (57/57 strings - no changes needed) ## [1.1.11] - 2025-12-31 ### Added - **FEATURE**: Variable product support - composable products can now include variable products and their variations - Variable products automatically expand to show all available variations as selectable items - Each variation displays with full attribute information (e.g., "Product - Color: Red, Size: Large") ### Fixed - Products not showing in selector when all available products were variable products - Variable products were being filtered out because parent products aren't directly purchasable ### Changed - Modified `get_available_products()` to detect and handle variable products - Variable products now expand into their individual variations - Each variation checked individually for stock status and purchasability - Simple products continue to work exactly as before ### Technical - Modified file: includes/Product_Type.php (lines 160-188) - Added logic to detect `is_type('variable')` products - Uses `get_available_variations()` to retrieve all variations - Each variation validated with `is_in_stock()` and `is_purchasable()` - Maintains backward compatibility with simple products ### Notes - This is a feature enhancement release, not a bug fix - Resolves the issue where categories containing only variable products showed no selections - Variations display with their parent product name plus selected attributes - Stock management works correctly for both simple products and variations - All translation files remain at 100% completion (57/57 strings - no new strings added) ## [1.1.10] - 2025-12-31 ### Fixed - **CRITICAL**: Admin panel - Both General and Composable tabs visible simultaneously on initial page load - **CRITICAL**: Frontend - No products showing in product selector, only cart button and pricing visible - Empty product grid now shows helpful message instead of blank space ### Changed - Added explicit `display: none` to `#composable_product_data` panel for proper initial hiding - Panel now only shows when `body.product-type-composable` class is present - Added empty state message in product selector template when no products are configured - Cleared Twig cache to ensure template changes take effect ### Added - Empty state message: "No products available for selection. Please configure the product criteria in the admin panel." - Translations for empty state message in all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH) - Recompiled .mo translation files ### Technical - Modified files: assets/css/admin.css (lines 7-16), templates/product-selector.twig (lines 12-15) - Root cause (admin): Panel lacked explicit CSS hiding rule, relied only on `hidden` class - Root cause (frontend): No feedback when products array is empty - Solution: CSS specificity + empty state conditional in Twig template ### Notes - This release fixes two critical bugs discovered immediately after v1.1.9 - Admin interface now correctly hides composable panel until product type is selected - Frontend provides clear user feedback when product selection is unavailable - All translation files now 100% complete (57/57 strings) ## [1.1.9] - 2025-12-31 ### Fixed - **CRITICAL**: Admin rendering completely broken - tabs disappeared and fields appeared out of context after v1.1.8 release - CSS selectors were too broad, hiding tab navigation along with field groups - Removed `!important` flags that caused overly aggressive hiding ### Changed - Made CSS selectors more specific: `.options_group.show_if_composable` for field groups only - Added separate rule for tab links: `.product_data_tabs li.composable_options` - Tab navigation now works correctly without hiding itself ### Technical - Modified files: assets/css/admin.css (lines 22-40) - Root cause: `.show_if_composable` class used by WooCommerce for both tab links AND field groups - Solution: Separate selectors for each use case to prevent unintended hiding ### Notes - This release fixes critical regression introduced in v1.1.8 - Admin interface now renders correctly with visible tabs and properly positioned fields - No `!important` flags needed with specific selectors ## [1.1.8] - 2025-12-31 ### Fixed - **CRITICAL**: Admin rendering bug where both General and Composable Options tabs showed simultaneously on initial page load - **CRITICAL**: Frontend product selector not appearing on product pages - WooCommerce's default add-to-cart button now hidden for composable products - **CRITICAL**: Price formatting not localized - prices now display with proper currency symbols, decimal separators, and thousand separators for all locales ### Added - `wc_price()` Twig function for proper price formatting in templates - `formatPrice()` JavaScript method with full WooCommerce locale support - Price format localization data passed to frontend JavaScript (decimal/thousand separators, currency position, number of decimals) - `hide_default_add_to_cart()` method to prevent WooCommerce's default purchase UI for composable products ### Changed - Enhanced CSS specificity with `!important` flags for proper tab visibility control - Template now uses `{{ fixed_price_html|raw }}` instead of raw currency concatenation - Product selector passes pre-formatted price HTML from `wc_price()` function - Frontend JavaScript updates prices dynamically using WooCommerce format settings ### Technical - Modified files: assets/css/admin.css (+24 lines), includes/Cart_Handler.php (+14 lines), includes/Plugin.php (+7 lines), includes/Product_Selector.php (+2 lines), templates/product-selector.twig, assets/js/frontend.js (+28 lines) - All PHP files pass syntax validation - Supports Swiss format (CHF 50.-), European format (50,00 €), US format ($50.00), and all other WooCommerce locales - Thousand separator support: comma (1,000), dot (1.000), apostrophe (1'000), space (1 000) ### Notes - This release fixes all three critical UI bugs reported in CLAUDE.md - Admin tabs now display correctly on initial page load without JavaScript flicker - Frontend product selector is now the only purchase interface (no WooCommerce default button) - All prices maintain proper locale formatting during dynamic updates ## [1.1.7] - 2025-12-31 ### Added - Compiled .mo translation files for all 6 supported locales (de_DE, de_DE_informal, de_CH, de_CH_informal, fr_CH, it_CH) - WordPress can now load translations in admin and frontend areas ### Fixed - **CRITICAL**: Missing translations in WordPress admin when using non-English locales - Settings page ("Composable Products", "Default Selection Limit", etc.) now properly translated - Product settings ("Composable Options", "Selection Criteria", etc.) now properly translated ### Technical - Compiled .mo files from .po sources using msgfmt - All 6 locales now have complete translation coverage (56/56 strings translated and compiled) - .mo files required for WordPress i18n system to display translations ### Notes - Previous versions included .po translation files but WordPress requires compiled .mo files - This release makes all existing translations actually visible to users ## [1.1.6] - 2025-12-31 ### Added - Complete translations for all admin area strings across all 6 supported locales - "Fixed Price" field label and description translations ### Changed - Updated translation template (.pot) to version 1.1.6 - Simplified "How to calculate the price" description text ### Technical - All .po files now include translations for v1.1.4 admin strings - 100% translation coverage maintained across all locales (56/56 strings) - German formal/informal variants properly differentiated (Sie vs. du) ## [1.1.5] - 2025-12-31 ### Fixed - **CRITICAL**: Fixed Twig template error "Unknown 'esc_attr' filter" when rendering product selector - Template compatibility issue when other plugins (e.g., WooCommerce Tier and Package Prices) use Twig - WordPress escaping functions now properly registered as both Twig functions AND filters ### Technical - Added `TwigFilter` registrations for `esc_html`, `esc_attr`, and `esc_url` in `Plugin::init_twig()` - Template can now use both syntax styles: `{{ value|esc_attr }}` (filter) and `{{ esc_attr(value) }}` (function) - Prevents conflicts when multiple plugins bundle their own Twig installations ### Notes - Previous versions only registered escaping functions as Twig functions, not filters - Template used filter syntax (`|esc_attr`) which failed when parsed by external Twig instances - Fix ensures compatibility regardless of which Twig instance processes the template ## [1.1.4] - 2025-12-31 ### Added - Fixed price field in Composable Options tab for easier price configuration - JavaScript toggle to show/hide fixed price field based on selected pricing mode ### Changed - Simplified pricing mode description text in admin interface - Fixed price field now appears dynamically when "Fixed" pricing mode is selected ### Technical - Added `_regular_price` field with `composable_fixed_price_field` CSS class in `Product_Data.php` - Implemented `toggleFixedPriceField()` JavaScript function in `assets/js/admin.js` - Progressive disclosure pattern improves admin UX by showing relevant fields only ## [1.1.3] - 2024-12-31 ### Added - WooCommerce HPOS (High-Performance Order Storage) compatibility declaration - Prevents duplicate price calculations to avoid conflicts with other pricing plugins ### Fixed - WooCommerce compatibility warnings with Analytics and other WooCommerce extensions - Price calculation conflicts with third-party pricing plugins ### Technical - Added `before_woocommerce_init` hook to declare HPOS compatibility - Implemented static flag in `Cart_Handler::calculate_cart_item_price()` to prevent multiple executions - Added `composable_price_calculated` flag to cart items to prevent re-calculation by other plugins - Ensures composable products work with WooCommerce's modern order storage system ## [1.1.2] - 2024-12-31 ### Fixed - **CRITICAL**: Fixed persistent "Class WC_Settings_Page not found" error that continued in v1.1.1 - Root cause: Settings.php was being included too early (during plugin init) before WC_Settings_Page was loaded - Solution: Delayed Settings.php inclusion until `woocommerce_get_settings_pages` filter when class is guaranteed to exist ### Technical - Removed `require_once Settings.php` from `Plugin::includes()` (line 93) - Added `require_once Settings.php` to `Plugin::add_settings_page()` (line 196) - Settings file now loads on-demand when WooCommerce requests settings pages - Previous hook change (woocommerce_init) was insufficient - class loading order was the real issue ### Notes - v1.1.1 attempted to fix this with hook change but the error persisted - This version addresses the actual root cause: premature class extension ## [1.1.1] - 2024-12-31 ### Fixed - Settings page initialization timing issue causing "Class WC_Settings_Page not found" error - Changed hook from `woocommerce_loaded` to `woocommerce_init` to ensure WC_Settings_Page class is available - Plugin now initializes after all WooCommerce core classes are loaded ### Technical - Hook changed from `woocommerce_loaded` to `woocommerce_init` in wc-composable-product.php:65 - `woocommerce_init` fires after WooCommerce has finished loading all its core classes including settings ## [1.1.0] - 2024-12-31 ### Added - **Stock Management Integration**: Complete inventory tracking system for composable products - Stock validation during product selection and add-to-cart - Automatic stock deduction when orders are completed/processed -

Low stock warnings when 5 or fewer items remain - Prevention of out-of-stock item selection - Order notes documenting stock changes ### Technical - New `Stock_Manager` class handling all stock operations - Integration with WooCommerce order status hooks - Stock information passed to frontend via Twig template - Enhanced CSS styling for stock status badges - Stock data stored in order item meta for accurate tracking - Backorder support detection and handling ### Translation - Added 8 new translatable strings for stock messages - Updated Italian (Switzerland) translation with stock-related terms - Updated translation template (.pot file) ## [1.0.1] - 2024-12-31 ### Fixed - Fatal error "Class WC_Settings_Page not found" during plugin activation - Changed initialization hook from `plugins_loaded` to `woocommerce_loaded` to ensure WooCommerce classes are available before plugin initialization - Settings page now correctly integrates as a tab in WooCommerce > Settings ### Technical - Plugin now waits for `woocommerce_loaded` action before initializing - Prevents race condition where WooCommerce classes weren't loaded yet - Settings tab appears correctly in WooCommerce settings interface ## [1.0.0] - 2024-12-31 ### Added - Initial release - Composable product type for WooCommerce - Product selection by category, tag, or SKU -
