Release version 1.1.5 - Critical bug fix for plugin activation

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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

+- ✅ Global setting to enable restrictions site-wide
+- ✅ Per-product override for individual products
+- ✅ Located in: WooCommerce > Settings > Tier & Package Prices
+
+## User Flow Comparison
+
+### Before v1.1.2
+**Shop Page:** "Add to Cart" button → **Result:** Ajax add fails with error OR quantity validation error
+
+### After v1.1.2
+**Shop Page:** "View Options" button → **Product Page:** Select package → **Add to Cart:** Success
+
+The improved flow eliminates customer confusion and failed add-to-cart attempts.
+
+## Use Cases
+
+### Scenario 1: Bulk-Only Product Catalog
+Enable restriction globally. Shop pages show "View Options" for all products.
+
+**Customer Experience:**
+- Browse shop → See "View Options" on bulk products
+- Click "View Options" → Product page opens
+- Select from available packages (e.g., 100, 250, 500 units)
+- Add to cart → Success with no errors
+
+### Scenario 2: Mixed Catalog
+Some products restricted, others not. Shop page shows appropriate buttons.
+
+**Customer Experience:**
+- Browse shop → See mix of "Add to Cart" and "View Options"
+- Regular products: "Add to Cart" works normally
+- Restricted products: "View Options" → Product page → Package selection
+
+### Scenario 3: Sample Pack Products
+Products sold only in fixed sample packs.
+
+**Customer Experience:**
+- Browse samples → All show "View Options"
+- Click button → Product page shows package choices
+- Select "Starter Pack (10)", "Trial Pack (25)", or "Full Pack (50)"
+- Quantity cannot be modified in cart

+
+## 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)

magdev	9765c5f119	Release version 1.1.5 - Critical bug fix for plugin activation CRITICAL FIX: Resolved fatal error that prevented plugin activation in versions 1.1.3 and 1.1.4.
