+# eBay Store Category Mapping
+
+## Overview
+
+This document describes how the FAS e-commerce platform synchronizes and maintains exact 3-level category hierarchy from eBay store to ensure perfect alignment between the website and eBay store categories.
+
+## Architecture
+
+### Database Schema
+
+Products now store the complete eBay store category hierarchy with 6 new columns:
+
+- `ebay_store_cat1_id` (INT) - Level 1 category ID
+- `ebay_store_cat1_name` (VARCHAR) - Level 1 category name (e.g., "MOTORCYCLE")
+- `ebay_store_cat2_id` (INT) - Level 2 category ID
+- `ebay_store_cat2_name` (VARCHAR) - Level 2 category name (e.g., "Honda")
+- `ebay_store_cat3_id` (INT) - Level 3 category ID
+- `ebay_store_cat3_name` (VARCHAR) - Level 3 category name (e.g., "CR500")
+
+All columns are indexed for efficient querying.
+
+### Category Hierarchy
+
+eBay stores support a 3-level category structure:
+
+1. **Level 1 (Top Level)**: Main product category (Motorcycle, ATV, Boat, etc.)
+2. **Level 2 (Manufacturer)**: Product manufacturer or subcategory
+3. **Level 3 (Model)**: Specific model or sub-subcategory
+
+### Synchronization Process
+
+When products are synced from eBay:
+
+1. The eBay API fetches store category IDs for each product
+2. The full category hierarchy is extracted using `getStoreCategories()`
+3. All 3 levels are stored in the database
+4. The hierarchy is preserved exactly as defined in the eBay store
+
+## Implementation Details
+
+### Product Model Methods
+
+#### `extractStoreCategoryHierarchy($storeCategoryId, $storeCategory2Id, $ebayAPI)`
+Extracts the complete 3-level hierarchy from eBay store categories.
+
+**Returns:**
+```php
+[
+    'cat1_id' => int|null,
+    'cat1_name' => string|null,
+    'cat2_id' => int|null,
+    'cat2_name' => string|null,
+    'cat3_id' => int|null,
+    'cat3_name' => string|null
+]
+```
+
+#### `getEbayStoreCategoryPath($product)`
+Returns a formatted category path string.
+
+**Example:**
+```php
+"MOTORCYCLE > Honda > CR500"
+```
+
+#### `getEbayStoreCategoryArray($product)`
+Returns categories organized by level.
+
+**Example:**
+```php
+[
+    1 => 'MOTORCYCLE',
+    2 => 'Honda',
+    3 => 'CR500'
+]
+```
+
+### Sync Behavior
+
+**For New Products:**
+- All 6 eBay store category columns are populated
+- The `category` field is set based on the mapped website category
+- Products maintain exact eBay store classification
+
+**For Existing Products:**
+- eBay store category columns are ALWAYS updated to match current eBay store structure
+- The `category` field is preserved (admin override)
+- This ensures eBay store changes are reflected while respecting admin customizations
+
+## Display
+
+### Product Detail Page
+Shows the full eBay store category path in the product details section:
+```
+eBay Category: MOTORCYCLE > Honda > CR500
+```
+
+### Admin Product List
+Hover over the "eBay" badge to see the full category path in a tooltip.
+
+### Admin Product Edit
+For products synced from eBay, displays the full category hierarchy with badges:
+- L1: MOTORCYCLE
+- L2: Honda
+- L3: CR500
+
+## Migration
+
+To add category support to an existing database:
+
+```bash
+php database/migrate-add-ebay-store-categories.php
+```
+
+This migration:
+- Adds all 6 new columns
+- Creates indexes
+- Is idempotent (safe to run multiple times)
+
+## Benefits
+
+1. **Exact Synchronization**: Website categories perfectly match eBay store structure
+2. **Data Preservation**: Products maintain their exact eBay classification
+3. **Automatic Updates**: Category changes in eBay store are reflected on next sync
+4. **No Data Loss**: All 3 levels preserved, no information discarded
+5. **Efficient Queries**: Indexed columns enable fast category-based searches
+
+## Future Enhancements
+
+Potential improvements:
+- Filter products by eBay store categories on website
+- Display category breadcrumbs on product listings
+- Category-based product recommendations
+- Store category analytics and reporting
+
+## Notes
+
+- The `category` field (motorcycle, atv, boat, etc.) remains for website navigation
+- eBay store categories are for reference and sync accuracy
+- Products without eBay categories (manual products) have null values in these columns
+- The hierarchy supports partial categorization (1, 2, or 3 levels)

+# Database Migration Guide
+
+## eBay Store Category Columns Migration
+
+This migration adds support for storing the complete 3-level eBay store category hierarchy in the products table.
+
+### What This Migration Does
+
+Adds 6 new columns to the `products` table:
+- `ebay_store_cat1_id` - Level 1 category ID (e.g., ID for "MOTORCYCLE")
+- `ebay_store_cat1_name` - Level 1 category name (e.g., "MOTORCYCLE")
+- `ebay_store_cat2_id` - Level 2 category ID (e.g., ID for "Honda")
+- `ebay_store_cat2_name` - Level 2 category name (e.g., "Honda")
+- `ebay_store_cat3_id` - Level 3 category ID (e.g., ID for "CR500")
+- `ebay_store_cat3_name` - Level 3 category name (e.g., "CR500")
+
+### How to Run the Migration
+
+**IMPORTANT:** You must run this migration before syncing products, otherwise you'll get an error like:
+```
+SQLSTATE[HY000]: General error: 1 table products has no column named ebay_store_cat1_id
+```
+
+#### Step 1: Navigate to the project directory
+```bash
+cd /path/to/FAS
+```
+
+#### Step 2: Run the migration script
+```bash
+php database/migrate-add-ebay-store-categories.php
+```
+
+#### Step 3: Verify the migration
+You should see output like:
+```
+Adding eBay store category columns to products table...
+Adding column 'ebay_store_cat1_id'...
+Adding column 'ebay_store_cat1_name'...
+Adding column 'ebay_store_cat2_id'...
+Adding column 'ebay_store_cat2_name'...
+Adding column 'ebay_store_cat3_id'...
+Adding column 'ebay_store_cat3_name'...
+
+Successfully added columns: ebay_store_cat1_id, ebay_store_cat1_name, ebay_store_cat2_id, ebay_store_cat2_name, ebay_store_cat3_id, ebay_store_cat3_name
+
+Migration completed successfully!
+```
+
+If the columns already exist, you'll see:
+```
+All eBay store category columns already exist. No changes needed.
+```
+
+### After Running the Migration
+
+Once the migration completes successfully, you can:
+1. Run eBay sync normally - products will now store the full 3-level category hierarchy
+2. View product details pages to see the complete category path (e.g., "MOTORCYCLE > Honda > CR500")
+3. Check admin product listings to see category information in tooltips
+
+### Troubleshooting
+
+**Error: Config file not found**
+- Make sure you have `src/config/config.php` set up
+- Copy `src/config/config.example.php` to `src/config/config.php` if needed
+
+**Error: Database not found**
+- Initialize the database first using `php database/init-sqlite.php`
+
+**Error: Permission denied**
+- Ensure the database file has write permissions
+- Check that the database directory is writable
+
+**Already ran but getting errors?**
+- The migration is idempotent (safe to run multiple times)
+- It will skip columns that already exist
+- If you see the error again after running successfully, check your database connection
+
+### Manual Migration (Alternative)
+
+If the automated script doesn't work, you can add the columns manually:
+
+**For SQLite:**
+```sql
+ALTER TABLE products ADD COLUMN ebay_store_cat1_id INTEGER;
+ALTER TABLE products ADD COLUMN ebay_store_cat1_name TEXT;
+ALTER TABLE products ADD COLUMN ebay_store_cat2_id INTEGER;
+ALTER TABLE products ADD COLUMN ebay_store_cat2_name TEXT;
+ALTER TABLE products ADD COLUMN ebay_store_cat3_id INTEGER;
+ALTER TABLE products ADD COLUMN ebay_store_cat3_name TEXT;
+```
+
+**For MySQL:**
+```sql
+ALTER TABLE products ADD COLUMN ebay_store_cat1_id INT NULL;
+ALTER TABLE products ADD COLUMN ebay_store_cat1_name VARCHAR(255) NULL;
+ALTER TABLE products ADD COLUMN ebay_store_cat2_id INT NULL;
+ALTER TABLE products ADD COLUMN ebay_store_cat2_name VARCHAR(255) NULL;
+ALTER TABLE products ADD COLUMN ebay_store_cat3_id INT NULL;
+ALTER TABLE products ADD COLUMN ebay_store_cat3_name VARCHAR(255) NULL;
+```
+
+### Support
+
+If you encounter issues:
+1. Check the error message carefully
+2. Verify your database is accessible
+3. Ensure PHP has permissions to modify the database
+4. Review the migration script at `database/migrate-add-ebay-store-categories.php`

Subject: [PATCH 08/24] Implement dynamic eBay category navigation with 3-tier
 sidebar

- Remove hard-coded categories from navigation menus
- Add getStoreCategoriesHierarchical() method to EbayAPI for hierarchical category structure
- Update Product model with getAllByEbayCategory() and getCountByEbayCategory() for filtering
- Replace products.php with sidebar showing eBay store categories (3 levels)
- Support filtering by eBay category IDs (cat1, cat2, cat3)
- Display full category path in product cards
- Remove category dropdown from header navigation (replaced with simple Products link)

Subject: [PATCH 09/24] Update admin product form to display eBay 3-tier
 categories clearly

- Relabel legacy "Category" field as "Website Category (Legacy)"
- Enhance eBay store category display with clear level indicators
- Show each of the 3 category levels (Level 1, Level 2, Level 3) separately
- Add warning when eBay categories are missing
- Clarify that eBay categories are auto-synced and read-only

Subject: [PATCH 13/24] Add comprehensive logging for eBay store category
 extraction

- Log when EbayAPI instance or store_category_id is missing
- Log API return status (null vs empty array vs data)
- Log count of categories retrieved from eBay GetStore API
- Log category lookup results (found/not found)
- Log each level extraction (L1, L2, L3) with names
- Log complete hierarchy result for each product during sync
- Shows exactly which API call is used (GetStore) and what data is received
- Helps diagnose why categories aren't being populated

Subject: [PATCH 14/24] Use GetItem API to fetch store category IDs for
 products

- Extract store_category_id and store_category2_id from GetItem API response
- GetItem returns Storefront data including StoreCategoryID and StoreCategory2ID
- Override GetSellerEvents category IDs with GetItem data (more reliable)
- GetItem is already called for every product to fetch SKU and condition
- Ensures products get accurate store category associations from authoritative source

Subject: [PATCH 15/24] Fix product.php mobile overflow and simplify category
 display

- Add max-width and overflow-x handling to prevent mobile overflow issues
- Add flex-shrink: 0 to thumbnail images to prevent squishing
- Remove old legacy category field (motorcycle/atv/boat categories)
- Rename "eBay Category" to just "Category" (now the primary category system)
- Add word-break styling to table cells for better mobile text wrapping
- Add white-space: nowrap to labels to prevent label wrapping

Subject: [PATCH 17/24] Fix subcategories display and prevent menu collapse on
 desktop

- Return updated sidebar HTML in AJAX response to show/hide subcategories dynamically
- Reattach category click handlers after sidebar update
- Move category handlers to reusable function attachCategoryHandlers()
- API now generates sidebar HTML when include_sidebar=1 parameter is set
- Subcategories now expand/collapse correctly based on selected category
- Mobile menu still auto-closes after selection as intended
- Desktop menu remains open while subcategories update dynamically

Subject: [PATCH 19/24] Add comprehensive error handling and debugging for AJAX
 loading

- Parse response as text first, then JSON for better error messages
- Log API responses to console for debugging
- Add null checks for sidebar container
- Provide specific error messages for JSON parse failures
- Log response text on parse errors to identify issues
- This should help identify why products don't appear after category change

Subject: [PATCH 20/24] Improve category sidebar UX - red active color and
 collapsed menu behavior

- Add red background color for active categories in light mode (matches theme)
- Change menu expansion behavior to show only active category path
- Only the selected category and its parent hierarchy remain expanded
- All other categories collapse to reduce clutter and improve navigation
- Example: Selecting Motorcycles > Kawasaki only shows those categories expanded
- Applied to both products.php and api/products.php for consistency

Subject: [PATCH 21/24] Add comprehensive error handling and debugging for AJAX
 API

- Add error handler to catch PHP errors and return as JSON
- Wrap JSON encoding in try-catch for better error reporting
- Add detailed console logging (response status, length, keys, content)
- Log first 500 and last 100 chars of response for debugging
- Show parsed data structure info in console
- Display specific error messages to users
- This will help identify why products HTML is not displaying after category change

Subject: [PATCH 23/24] Fix AOS animation blocking product display after AJAX
 load

- Add setTimeout wrapper for AOS refresh to allow DOM to settle
- Dispatch scroll event to trigger AOS animations immediately
- This fixes issue where products HTML was inserted but not visible
- AOS was waiting for scroll/intersection events that never fired on dynamic content
- Products now display immediately after category selection

Subject: [PATCH 24/24] Disable AOS animations on AJAX-loaded products to fix
 visibility

- Remove data-aos attributes from dynamically loaded content
- Remove AOS classes (aos-init, aos-animate) that hide elements
- Clear AOS inline styles (opacity, transform) that keep products invisible
- Products now display immediately after AJAX load without animation delay
- AOS animations still work on initial page load
- This fixes the issue where products existed in DOM but were completely invisible
