CRITICAL FIX: The previous CSS change used .show_if_composable with !important
which hid ALL elements with that class, including the tab links themselves.
Changes:
- Changed from .show_if_composable to .options_group.show_if_composable
- Changed from .product_data_tabs .composable_options to li.composable_options
- Removed !important flags (not needed with specific selectors)
- Now only hides the general tab option groups, not the tab links
This fixes:
- Missing Composable Options tab in product edit screen
- Fields appearing out of context
- Tab navigation completely broken
The issue was that WooCommerce adds 'show_if_composable' class to BOTH:
1. The tab link (li.composable_options.show_if_composable)
2. The general tab fields (div.options_group.show_if_composable)
Now we specifically target only the option groups, leaving tabs alone.

Fixes three critical bugs reported in CLAUDE.md:
1. Admin rendering bug - Fixed CSS to prevent both General and Composable
Options tabs from showing simultaneously on initial page load
- Enhanced CSS specificity with !important flags
- Added body.product-type-composable selectors for proper visibility control
- Hides Composable Options tab by default, shows only when composable type selected
2. Frontend product selector not appearing - Fixed WooCommerce integration
- Added hide_default_add_to_cart() method to Cart_Handler
- Hooks woocommerce_is_purchasable filter to return false for composable products
- This hides WooCommerce's default add-to-cart button
- Allows our custom product selector to be the only interface
3. Localized price formatting - Implemented proper WooCommerce price formatting
- Added wc_price Twig function in Plugin.php
- Updated Product_Selector to pass formatted price HTML to template
- Added price_format data to JavaScript localization
- Implemented formatPrice() method in frontend.js
- Supports all WooCommerce price formats (currency position, decimals, separators)
- Template now uses {{ fixed_price_html|raw }} and {{ zero_price_html|raw }}
- JavaScript dynamically formats prices using locale-specific settings
Technical improvements:
- Cart_Handler.php: +14 lines (hide_default_add_to_cart method)
- Plugin.php: +7 lines (wc_price function, price format localization)
- Product_Selector.php: +2 lines (formatted price HTML context)
- templates/product-selector.twig: Modified to use formatted price HTML
- assets/css/admin.css: +24 lines (enhanced tab visibility control)
- assets/js/frontend.js: +28 lines (formatPrice method with WooCommerce format support)
All PHP files pass lint checks. Frontend now properly displays localized prices
with correct currency symbols, decimal separators, and thousand separators for
all WooCommerce-supported locales (CHF for Switzerland, € for Europe, etc.).

CRITICAL FIX: WordPress plugin directory structure
Previous issue:
- ZIP contained files at root level
- WordPress created directory based on ZIP name: wc-composable-product-v1.1.7/
- This caused version-numbered directory in wp-content/plugins/
Corrected structure:
- ZIP now contains wc-composable-product/ parent directory
- All plugin files inside wc-composable-product/ directory
- WordPress extracts to wp-content/plugins/wc-composable-product/ (correct!)
Changes:
- Recreated ZIP with proper directory structure using rsync + zip
- Package size: 410 KB (419,697 bytes) - slightly larger due to parent dir
- New SHA-256: 866e7dd34431f4c881629fd8b59ddd3a27c7a45b7324a3d88cd064a3e01c1b83
- New MD5: 871fbb3b910380c0e43bcf1538408eda
WordPress standard: Plugin ZIP must contain single parent directory named after
the plugin slug, with all files inside that directory.

Document the critical bug fix journey for the WC_Settings_Page error:
v1.1.1 session (failed attempt):
- Attempted to fix with hook timing change
- Changed to woocommerce_init hook
- Bug persisted - error logs showed it still failed
- Lesson: Always verify fixes with error logs
v1.1.2 session (successful fix):
- Discovered root cause: Settings.php loaded too early
- require_once happened during Plugin::includes()
- PHP tried to parse 'extends WC_Settings_Page' before class existed
- Solution: Delayed require_once to add_settings_page() callback
- This callback runs when WC has loaded all settings classes
Key learnings documented:
1. Class loading order matters more than hook timing
2. Always verify fixes don't just assume they work
3. Lazy loading pattern for extending third-party classes
4. Read error logs thoroughly - backtrace reveals the sequence
5. Don't assume hook order means all classes are loaded
6. Test immediately after each release
Also documents the debugging approach that worked and the
5-version journey to finally fix this persistent issue.

Release v1.1.2 - CRITICAL bug fix for Settings.php class loading
This release fixes the persistent WC_Settings_Page error that affected all previous versions including v1.1.1.
Root cause:
- Settings.php extends WC_Settings_Page
- File was being required during Plugin::includes()
- WC_Settings_Page class didn't exist at that point
- Hook timing changes (v1.0.1, v1.1.1) were insufficient
Solution implemented:
- Removed require_once from Plugin::includes()
- Moved to Plugin::add_settings_page() callback
- Loads on-demand via woocommerce_get_settings_pages filter
- WC_Settings_Page guaranteed to exist at that point
Package contents:
- Plugin source files (v1.1.2)
- Stock management integration (v1.1.0 feature)
- Complete vendor dependencies (Twig 3.0)
- Translation files for 6 locales
- Documentation and changelog

CRITICAL BUG FIX: v1.1.1 still had the same error!
Root cause analysis:
- v1.1.1 changed hook to woocommerce_init but error persisted
- Real issue: Settings.php was require_once'd in Plugin::includes()
- At that point, class extends WC_Settings_Page which doesn't exist yet
- Even woocommerce_init fires before WC_Settings_Page is loaded
Solution:
- Removed require_once from Plugin::includes() (line 93)
- Moved require_once to Plugin::add_settings_page() (line 196)
- Settings.php now loads on-demand via woocommerce_get_settings_pages filter
- This filter fires when WooCommerce has loaded all settings classes
Changes:
- includes/Plugin.php: Delayed Settings.php inclusion with explanatory comment
- wc-composable-product.php: Version bump to 1.1.2
- CHANGELOG.md: Documented fix and noted v1.1.1 was insufficient
This addresses the actual root cause that persisted through 3 versions.
