Release version 1.1.15 - Fix duplicate settings page

Fixed settings page appearing twice in WooCommerce settings due to double instantiation of WC_TPP_Settings class.

**Issue:**
- Settings page rendered twice on same page
- WC_TPP_Settings class instantiated twice: once automatically in settings file, once via admin class include

**Fix:**
- 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

**Files Modified:**
- includes/class-wc-tpp-settings.php (simplified return statement)

+
+## [1.1.14] - 2025-12-22

+
+### Sample Packs
+Create fixed sample packs with no custom quantities.
+
+**Example:**
+- Starter Pack: 10 items
+- Trial Pack: 25 items
+- Full Pack: 50 items
+
+### Promotional Bundles
+Offer promotional pricing only for specific bundle sizes.
+
+**Example:**
+- Holiday Bundle: 12 units (seasonal pricing)
+- Party Pack: 24 units (bulk discount)
+- Wholesale Bundle: 100 units (wholesale pricing)
+
+## Configuration Examples
+
+### Example 1: Site-Wide Restriction
+
+**Scenario:** All products should only be sold in packages
+
+**Configuration:**
+1. Go to WooCommerce > Settings > Tier & Package Prices
+2. Check "Restrict to Package Quantities"
+3. Save changes
+4. Configure package sizes for each product
+
+**Result:** All products with packages defined will enforce quantity restrictions
+
+### Example 2: Per-Product Restriction
+
+**Scenario:** Only specific products need quantity restrictions
+
+**Configuration:**
+1. Leave global setting unchecked
+2. Edit the specific product
+3. Scroll to Package Pricing section
+4. Check "Restrict to Package Quantities"
+5. Update product
+
+**Result:** Only that product enforces restrictions
+
+### Example 3: Mixed Approach
+
+**Scenario:** Most products are restricted, but some allow custom quantities
+
+**Configuration:**
+1. Enable global restriction
+2. For products that should allow custom quantities, simply don't define any packages
+3. Products without packages defined won't show restrictions

+- ✅ WordPress 6.0+

+
+## What's New in 1.1.3
+
+This is a **bug fix release** that resolves cart quantity input visibility issues for products with package quantity restrictions.
+
+### Bug Fixes
+- **Cart Quantity Input Visibility** - FIXED
+  - Cart quantity inputs now properly hidden with increased filter priority (999)
+  - Mini-cart/sidebar quantity inputs correctly replaced with read-only text
+  - Added fallback CSS injection to handle theme/plugin conflicts
+  - Enhanced DOM targeting with data attributes and multiple CSS selectors
+
+### Technical Enhancements
+- Increased filter priority from 10 to 999 for `woocommerce_cart_item_quantity`
+- Added `woocommerce_widget_cart_item_quantity` filter for mini-cart support
+- Added `add_cart_quantity_css()` method for dynamic CSS injection
+- Added `maybe_hide_mini_cart_quantity_input()` method in WC_TPP_Cart class
+- Enhanced quantity spans with `data-product-id` attribute for targeted CSS
+- Added `wc-tpp-restricted-qty` CSS class for improved targeting
+- Implemented both sibling (+) and general sibling (~) CSS selectors for various DOM structures
+
+## Problem Solved
+
+**Issue:** In version 1.1.1 and 1.1.2, cart quantity inputs were still visible in the main cart and mini-cart/sidebar for products with package quantity restrictions, despite the feature being implemented.
+
+**Root Cause:**
+1. Filter priority was too low (10), allowing other plugins to override
+2. Mini-cart used different filter hook (`woocommerce_widget_cart_item_quantity`)
+3. Some themes/plugins had DOM structures that prevented proper hiding
+4. No fallback mechanism for edge cases
+
+**Solution:**
+1. Increased filter priority to 999 to ensure execution after other plugins
+2. Added separate filter for mini-cart quantity display
+3. Implemented dynamic CSS injection as fallback for all edge cases
+4. Used data attributes for product-specific CSS targeting
+5. Applied multiple CSS selectors (sibling + general sibling) to handle DOM variations
+
+## What's Changed
+
+### Fixed
+- Cart quantity input visibility issue in cart and cart sidebar for restricted products
+- Enhanced filter priority (999) to ensure quantity hiding runs after other plugins
+- Mini-cart quantity input now properly hidden for restricted products
+
+### Added
+- `woocommerce_widget_cart_item_quantity` filter support for mini-cart
+- `add_cart_quantity_css()` method for dynamic CSS injection
+- `data-product-id` attribute to quantity spans for targeted CSS selectors
+- CSS class `wc-tpp-restricted-qty` for improved targeting
+
+### Technical
+- Increased filter priority from 10 to 999 for `woocommerce_cart_item_quantity`
+- Added `maybe_hide_mini_cart_quantity_input()` method in WC_TPP_Cart class
+- Dynamic CSS injection via `wp_head` action as fallback
+- Used both sibling (+) and general sibling (~) CSS selectors for DOM variations

+
+## Technical Implementation Details
+
+### Cart Quantity Hiding Strategy (v1.1.3)
+
+The implementation uses a multi-layered approach to ensure reliability:
+
+**Layer 1: Filter Replacement**
+```php
+// High priority (999) to run after other plugins
+add_filter('woocommerce_cart_item_quantity', 'maybe_hide_cart_quantity_input', 999, 3);
+add_filter('woocommerce_widget_cart_item_quantity', 'maybe_hide_mini_cart_quantity_input', 999, 3);
+```
+
+**Layer 2: HTML Replacement**
+Replace quantity input with read-only span:
+```php
+sprintf('<span class="wc-tpp-cart-quantity wc-tpp-restricted-qty" data-product-id="%d">%s</span>',
+    $product_id,
+    $cart_item['quantity']
+);
+```
+
+**Layer 3: CSS Fallback**
+Dynamic CSS injection for edge cases:
+```php
+.cart_item .wc-tpp-restricted-qty[data-product-id="123"] + .quantity,
+.cart_item .wc-tpp-restricted-qty[data-product-id="123"] ~ .quantity {
+    display: none !important;
+}
+```
+
+This three-layer approach ensures cart quantity inputs are hidden regardless of theme, plugin conflicts, or DOM structure variations.

+
+## Technical Implementation Details
+
+### WooCommerce Blocks Integration (v1.1.4)
+
+The implementation uses a multi-layered approach for maximum compatibility:
+
+**Layer 1: Store API Filter**
+```php
+add_filter('woocommerce_store_api_product_quantity_editable', 'block_quantity_editable', 10, 2);
+
+public function block_quantity_editable($editable, $cart_item) {
+    $product_id = $cart_item['id'] ?? ($cart_item['product_id'] ?? 0);
+    // Check restrictions...
+    return false; // Make non-editable for restricted products
+}
+```
+
+**Layer 2: CSS Hiding**
+```css
+.wc-block-cart-item[data-product-id="123"] .wc-block-components-quantity-selector,
+.wc-block-mini-cart__items .wc-block-cart-item[data-product-id="123"] .wc-block-components-quantity-selector {
+    display: none !important;
+}
+```
+
+**Layer 3: Enhanced Button Styling**
+```css
+a.wc-tpp-view-options {
+    padding: 0.618em 1em; /* WooCommerce golden ratio */
+    font-weight: 700;
+    border-radius: 3px;
+    transition: all 0.2s ease;
+}
+```
+
+This three-layer approach ensures compatibility with:
+- ✅ Classic WooCommerce templates
+- ✅ WooCommerce Blocks (Cart Block, Mini-Cart Block)
+- ✅ All themes (inherits theme button colors)
+- ✅ All cart/mini-cart variations

+# WooCommerce Tier and Package Prices - Release 1.1.6
+
+**Release Date:** December 22, 2025
+**Version:** 1.1.6
+**Package Size:** 54 KB
+**Git Tag:** v1.1.6
+
+## Download
+
+**File:** `wc-tier-and-package-prices-1.1.6.zip`

+dbea10acffdc849f9aa387d128cb6d6e
+```
+
+## What's New in 1.1.6
+
+This is a **critical bug fix release** that resolves fatal errors introduced in versions 1.1.3, 1.1.4, and 1.1.5 during plugin activation.
+
+### Critical Fixes
+- **Plugin Activation Fatal Error** - FIXED
+  - Fatal error caused by premature class instantiation before WooCommerce is loaded
+  - Removed immediate class instantiation from `class-wc-tpp-cart.php` and `class-wc-tpp-frontend.php`
+  - Ensures WooCommerce is fully loaded before registering hooks that depend on WC functions
+
+### Technical Changes
+- Moved `WC_TPP_Cart` and `WC_TPP_Frontend` instantiation to `woocommerce_loaded` hook
+- Added `init_classes()` method to main plugin class for controlled class initialization
+- Fixed hook registration timing to prevent accessing WooCommerce before it's available
+
+## What Was Fixed
+
+### The Problem (v1.1.3, v1.1.4, v1.1.5)
+
+The previous three versions had a critical bug that caused fatal errors during plugin activation:
+
+**Error Message:**
+```
+Fatal error: Call to undefined function WC()
+Fatal error: Call to undefined function is_cart()
+Fatal error: Call to undefined function is_checkout()
+```
+
+**Root Cause:**
+- Classes `WC_TPP_Cart` and `WC_TPP_Frontend` were instantiated immediately in their files
+- These classes register hooks that call WooCommerce functions (`WC()`, `is_cart()`, etc.)
+- During plugin activation, these files are included before WooCommerce is loaded
+- Hook registration attempts to call undefined WooCommerce functions
+- Result: Fatal error and plugin activation failure
+
+**Impact:**
+- Plugin could not be activated on fresh installations
+- Plugin could not be updated from v1.1.2 or earlier
+- Affected all users attempting to install/update in v1.1.3-v1.1.5
+
+### The Solution (v1.1.6)
+
+**Before (v1.1.3-v1.1.5):**
+```php
+// At bottom of class-wc-tpp-cart.php and class-wc-tpp-frontend.php
+new WC_TPP_Cart();    // Instantiated immediately!
+new WC_TPP_Frontend(); // Instantiated immediately!
+```
+
+**After (v1.1.6):**
+```php
+// In main plugin file (wc-tier-and-package-prices.php)
+private function includes() {
+    // ... require files ...
+
+    // Instantiate classes AFTER WooCommerce is loaded
+    add_action('woocommerce_loaded', array($this, 'init_classes'));
+}
+
+public function init_classes() {
+    new WC_TPP_Frontend();
+    new WC_TPP_Cart();
+}
+```
+
+**Why This Works:**
+1. Class files are required but not instantiated during `includes()`
+2. Main plugin hooks into `woocommerce_loaded` action
+3. WooCommerce fully loads and defines all functions
+4. `init_classes()` is called, safely instantiating classes
+5. All WooCommerce functions are available when hooks are registered
+

+
+**Admin Experience:**

+- Appears below "Price per Unit" field
+- Placeholder: "e.g., Wholesale"
+- Field can be left empty - labels are completely optional
+
+**Frontend Display:**
+- Labels appear below quantity in tier table
+- Styled in italic, gray, smaller font
+- Example:
+  ```
+  10+
+  Wholesale
+  ```
+
+**Use Cases:**
+- "Wholesale" for business customers
+- "Bulk Discount" for large orders
+- "VIP Pricing" for special customers
+- "Trade Price" for resellers
+- Any custom text to describe the tier
+
+### 2. Clickable Tier Rows
+
+**User Experience:**
+1. Customer views tier pricing table on product page
+2. Hovers over any tier row - sees cursor change and subtle animation
+3. Clicks on desired tier row
+4. Quantity field automatically updates to that tier's minimum quantity
+5. Page smoothly scrolls to bring quantity field into view
+6. Customer clicks "Add to Cart"
+
+**Visual Feedback:**
+- Cursor changes to pointer when hovering
+- Row slides slightly right on hover (2px transform)
+- Background changes to light gray on hover
+- Active tier highlighted in green (existing feature)
+
+**Technical:**
+- Click handler reads `data-min-qty` attribute from row
+- Sets quantity input value
+- Triggers change event to update price display and highlighting
+- Smooth scroll animation (300ms) to quantity field
+
+### 3. Add to Cart Button Auto-Disable
+
+**Behavior:**
+- On page load, checks if quantity is 0 and disables button if needed
+- Every time quantity changes (manual input, tier click, package selection), updates button state
+- Quantity ≤ 0: Button disabled
+- Quantity > 0: Button enabled
+
+**Visual Feedback When Disabled:**
+- Opacity reduced to 50%
+- Cursor changes to not-allowed
+- Pointer events disabled (can't click)
+
+**Use Cases:**
+- Prevents "Add to Cart" with quantity 0
+- Prevents "Add to Cart" with negative quantities
