Fixed two critical bugs introduced in v1.2.0:
1. Admin UI table structure mismatch - CSS still had flexbox styling from
old template structure, breaking new table layout. Updated admin.css to
properly style table rows with standard table cell padding.
2. Frontend pricing display not showing - Template was checking global
enable settings before display. Removed those checks so pricing shows
if configured on product AND display setting is enabled.

Fixed persistent duplicate settings page by improving duplicate detection
to check by class type and ID instead of strict instance comparison.
Issue:
- Strict instance comparison (===) failed to detect duplicates
- Different object instances of same class not caught by previous check
- Settings page still appearing twice despite singleton and instance caching
Solution:
- Changed duplicate detection from instance comparison to type/ID checks
- Added instanceof WC_TPP_Settings check
- Added get_id() method check for ID 'tier_package_prices'
- Added direct id property check as fallback
- Multiple layers of detection to catch duplicates regardless of how created
Fixes:
- Settings page rendering twice in WooCommerce backend
- Duplicate detection failing for different instances of same class
Changes:
- Enhanced add_settings_page() with multi-layer duplicate detection
- Checks: instanceof, get_id(), and id property
- Returns early if any existing page matches criteria
Technical Details:
- Strict comparison only works if exact same object instance
- Different instances (even of same class/ID) fail === check
- instanceof checks class type regardless of which instance
- ID checks ensure no duplicate pages with same identifier
- Fallback checks handle different WooCommerce versions/implementations
Updated Files:
- includes/class-wc-tpp-admin.php (enhanced duplicate detection)
- wc-tier-and-package-prices.php (version 1.1.19)
- composer.json (version 1.1.19)

Identified and fixed the actual root cause of duplicate settings page:
automatic instantiation in settings file being executed multiple times.
Root Cause Analysis:
- Settings file ended with: return new WC_TPP_Settings();
- File is in Composer's classmap for autoloading
- When autoloader loads class, it executes the entire file including instantiation
- Each include/autoload created a NEW instance despite admin singleton pattern
- Admin singleton prevented multiple admin instances but not multiple settings instances
The Fix:
- Removed automatic instantiation (return new) from settings file
- Settings file now only contains class definition
- Admin class explicitly creates instance: new WC_TPP_Settings()
- Changed from include to require_once to prevent multiple file loads
- Settings instance now created exactly once, when filter needs it
Fixes:
- Settings page rendering twice in WooCommerce backend
- Multiple WC_TPP_Settings instances being created
- Composer autoload triggering unintended instantiation
Changes:
- Removed line 145 from class-wc-tpp-settings.php (return new WC_TPP_Settings())
- Modified add_settings_page() to use require_once + explicit new
- Settings file now side-effect free, safe for autoloading
Technical Details:
- Composer classmap autoloader includes files when class is referenced
- Previous code had side effect (instantiation) on every include
- New code separates class definition from instantiation
- Instance creation now controlled explicitly by admin class
- require_once ensures file loaded once even if accessed multiple times
Updated Files:
- includes/class-wc-tpp-settings.php (removed return new line)
- includes/class-wc-tpp-admin.php (explicit instantiation)
- wc-tier-and-package-prices.php (version 1.1.18)

Fixed persistent duplicate settings page by adding array-level duplicate
detection in addition to singleton pattern from v1.1.16.
Root Cause:
- WooCommerce calls woocommerce_get_settings_pages filter multiple times
- Even with singleton pattern, each filter call added settings instance to array
- Singleton prevented multiple class instances but not multiple array entries
Fixes:
- Settings page rendering twice despite singleton pattern in v1.1.16
- Filter adding same settings instance to array on repeated calls
Changes:
- Added duplicate detection loop in add_settings_page() before array append
- Uses strict comparison (===) to check if instance already in array
- Returns early if settings page already present, preventing duplicate
Technical Details:
- foreach loop iterates through existing $settings array
- Compares each element against cached self::$settings_instance
- Only appends to array if instance not found
- Complements singleton pattern with array-level protection
- Handles WooCommerce calling filter multiple times during page load
Updated Files:
- includes/class-wc-tpp-admin.php (added duplicate check in filter)
- wc-tier-and-package-prices.php (version 1.1.17)
- composer.json (version 1.1.17)

Fixed persistent duplicate settings page rendering by implementing proper
singleton pattern for admin class and caching settings instance.
Fixes:
- Settings page still appearing twice despite v1.1.15 fix
- Multiple instantiation of WC_TPP_Admin class
- Duplicate creation of WC_TPP_Settings instances
Changes:
- Implemented singleton pattern for WC_TPP_Admin class
- Added private static $instance property with get_instance() method
- Made WC_TPP_Admin constructor private
- Added static $settings_instance property to cache settings page
- Modified add_settings_page() to check and reuse cached settings instance
- Changed instantiation from new WC_TPP_Admin() to WC_TPP_Admin::get_instance()
Technical Details:
- Ensures only one WC_TPP_Admin instance exists throughout plugin lifecycle
- Prevents duplicate filter registrations even if woocommerce_get_settings_pages called multiple times
- Settings page object created once and reused on subsequent filter calls
- Follows WordPress/WooCommerce best practices for singleton implementation
Updated Files:

- Removed conditional wrapper `if (class_exists('WC_TPP_Settings'))` from settings return statement
- Settings class now only instantiated when admin class includes the file via `return new WC_TPP_Settings();`
- Restored v1.1.2 pattern for settings file

**CRITICAL FIX:** Restored plugin to working state after v1.1.8-1.1.13 were completely non-functional.
**Root Cause:**
- v1.1.8 moved class instantiation from individual files to init_classes() method
- v1.1.13 wrapped classes in class_exists() guards
- Combination prevented any classes from being instantiated
- Result: No settings, no frontend, no backend functionality
**Solution:**
- Reverted to v1.1.2 pattern (last working version)
- Each class file now instantiates itself with `new ClassName();`
- Removed init_classes() method and woocommerce_loaded hook
- All class_exists() guards remain for redeclaration protection
**What Now Works:**
✅ WooCommerce Settings → Tier & Package Prices tab
✅ Product edit pages show tier/package pricing meta boxes
✅ Frontend displays pricing tables on product pages
✅ Cart applies tier/package pricing correctly
✅ All plugin functionality fully operational
**Files Modified:**
- includes/class-wc-tpp-admin.php

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

1. Plugin file loaded
2. Classes defined (but not instantiated)
3. WooCommerce loads
4. woocommerce_loaded hook fires

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

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 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())
