## Order Status Workflow

### Status Progression:
```
Pending/New Order
       ↓
    Packed (vendor prepares order)
       ↓
   Dispatched (handed to courier)
       ↓
   In Transit (shipping in progress)
       ↓
Out For Delivery (out for final delivery)
       ↓
   Delivered (customer received)

Alternative:
    Cancelled (order cancelled at any stage)
```

### Vendor Actions:
1. **New Order** → Mark as "Packed" when ready
2. **Packed** → Update to "Dispatched" when shipped
3. **Dispatched** → Update to "In Transit"
4. **In Transit** → Update to "Out For Delivery"
5. **Out For Delivery** → Mark "Delivered" when confirmed

---

## Security Implementation

### Ownership Verification:
Every order page verifies the product belongs to the vendor:

```php
// In order-details.php
SELECT o.*, p.vendor_id
FROM orders o 
JOIN products p ON o.productId = p.id 
WHERE o.id = [order_id] AND p.vendor_id = [vendor_id]

if (mysqli_num_rows($query) == 0) {
    // Unauthorized - redirect to all-orders.php
}
```

This prevents vendors from:
- Viewing other vendors' orders
- Updating other vendors' order status
- Accessing unauthorized order data

---

## Database Operations

### Status Update:
```php
// Update order status
UPDATE orders 
SET orderStatus = 'Dispatched' 
WHERE id = [order_id]

// Create tracking entry
INSERT INTO ordertrackhistory (orderId, status, remark) 
VALUES ([order_id], 'Dispatched', 'Shipped via courier')
```

### Tracking History Query:
```sql
SELECT * FROM ordertrackhistory 
WHERE orderId = [order_id] 
ORDER BY id DESC
```

---

## Print Functionality

### Implementation:
- Print button in header
- CSS media query for print layout
- Hides navigation, buttons, forms on print
- Shows only order information
- Clean invoice-style layout

**CSS:**
```css
@media print {
    .no-print, .sb-topnav, #layoutSidenav_nav, .page-header {
        display: none !important;
    }
}
```

---

## UI/UX Features

### Order List Tables:
- DataTables for powerful search
- Sortable columns
- Product image thumbnails
- Formatted currency (₵ symbol)
- Date formatting (M d, Y)
- Status color coding

### Order Details Layout:
- Two-column layout (8-4 grid)
- Left: Order info, product, customer
- Right: Status update form, tracking history
- Responsive design
- Print-optimized

### Status Update:
- Dropdown pre-selects current status
- Optional remarks field
- Success message after update
- Redirects back to details page

---

## Statistics & Metrics

### Dashboard Metrics:
- **Total Orders:** COUNT of all orders
- **Pending Orders:** COUNT where status is NULL/empty/Packed
- Displayed as stat cards
- Real-time calculation from database

### Calculated Values:
```php
// Total amount per order
$totalAmount = $productPrice * $quantity
```

---

- "View Orders" → all-orders.php

- Quick actions integrated

### Links from Product List:
- (Future) View orders for specific product

## Error Handling
