### Next Steps:

1. **Run Database Migration:**
   ```sql
   -- Import the updated schema.sql or run these commands:
   USE event_order;
   
   CREATE TABLE IF NOT EXISTS crystals (
       id INT AUTO_INCREMENT PRIMARY KEY,
       name VARCHAR(100) NOT NULL,
       image_path VARCHAR(255) DEFAULT NULL,
       description TEXT,
       display_order INT DEFAULT 0,
       created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
   );
   
   INSERT INTO crystals (name, image_path, description, display_order) VALUES
   ('Crystal 1', 'uploads/crystal1.jpg', 'Premium crystal type 1', 1),
   ('Crystal 2', 'uploads/crystal2.jpg', 'Premium crystal type 2', 2),
   ('Crystal 3', 'uploads/crystal3.jpg', 'Premium crystal type 3', 3),
   ('Crystal 4', 'uploads/crystal4.jpg', 'Premium crystal type 4', 4),
   ('Crystal 5', 'uploads/crystal5.jpg', 'Premium crystal type 5', 5),
   ('Crystal 6', 'uploads/crystal6.jpg', 'Premium crystal type 6', 6),
   ('Crystal 7', 'uploads/crystal7.jpg', 'Premium crystal type 7', 7);
   ```

2. **Replace Crystal Images:**
   - Upload your actual crystal images to the `uploads/` folder
   - Name them: crystal1.jpg, crystal2.jpg, crystal3.jpg, etc.
   - Or update the image_path in the database to match your file names

3. **Test the Application:**
   - Visit http://localhost/pos_crown1/index.php
   - Follow the 3-step customization process
   - Verify all validations work correctly

## Notes
- All validation messages in English
- Crystal images will be small (50x50px)
- Placeholder images use SVG fallback if actual images not found
- Single page flow - no redirect to customize.php
- Cart.php already handles custom items with crystal breakdown
