# Notification System Enhancements - Implementation Plan

## Overview

This document outlines the complete implementation plan for notification system enhancements, including dynamic URLs, activity logging, and customer notifications.

---

## 1. Customer Email Notifications

### Current State
- WooCommerce handles customer emails automatically
- WooNooW notifications are for admin alerts only
- Recipient field exists but not fully utilized

### Strategy: Integration, Not Replacement

**Decision:** Keep WooCommerce's customer email system, add admin notification layer

**Why:**
- ✅ WooCommerce emails are battle-tested
- ✅ Merchants already customize them
- ✅ Templates, styling, and logic already exist
- ✅ We focus on admin experience

**What We Add:**
- Admin notifications (email + push)
- Real-time alerts for admins
- Activity logging
- Better UI for managing notifications

### Implementation

**No code changes needed!** System already supports:
- `recipient: 'admin'` - Admin notifications
- `recipient: 'customer'` - Customer notifications (via WooCommerce)
- `recipient: 'both'` - Both (admin via WooNooW, customer via WooCommerce)

**Documentation Update:**
- Clarify that customer emails use WooCommerce
- Document integration points
- Add filter for custom recipient logic

---

## 2. Activity Log System

### Current State
- WooCommerce has order notes (limited)
- No comprehensive activity log
- No UI for viewing all activities

### Strategy: Build Custom Activity Log

**Why Build Our Own:**
- ✅ Full control over what's logged
- ✅ Better UI/UX
- ✅ Searchable and filterable
- ✅ Integration with notifications
- ✅ Real-time updates

### Data Structure

```php
// wp_woonoow_activity_log table
CREATE TABLE wp_woonoow_activity_log (
    id BIGINT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    user_id BIGINT UNSIGNED NOT NULL,
    action VARCHAR(50) NOT NULL,
    object_type VARCHAR(50) NOT NULL,
    object_id BIGINT UNSIGNED NOT NULL,
    description TEXT,
    metadata LONGTEXT, -- JSON
    ip_address VARCHAR(45),
    user_agent TEXT,
    created_at DATETIME NOT NULL,
    INDEX idx_user_id (user_id),
    INDEX idx_action (action),
    INDEX idx_object (object_type, object_id),
    INDEX idx_created_at (created_at)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
```

### Activity Types

**Orders:**
- `order.created` - Order created
- `order.updated` - Order updated
- `order.status_changed` - Status changed
- `order.payment_completed` - Payment completed
- `order.refunded` - Order refunded
- `order.deleted` - Order deleted

**Products:**
- `product.created` - Product created
- `product.updated` - Product updated
- `product.stock_changed` - Stock changed
- `product.deleted` - Product deleted

**Customers:**
- `customer.created` - Customer registered
- `customer.updated` - Customer updated
- `customer.deleted` - Customer deleted

**Notifications:**
- `notification.sent` - Notification sent
- `notification.failed` - Notification failed
- `notification.clicked` - Notification clicked

**Settings:**
- `settings.updated` - Settings changed
- `channel.toggled` - Channel enabled/disabled
- `event.toggled` - Event enabled/disabled

### Implementation Files

**Backend:**
1. `includes/Core/ActivityLog/Logger.php` - Main logger class
2. `includes/Core/ActivityLog/ActivityLogTable.php` - Database table
3. `includes/Api/ActivityLogController.php` - REST API
4. Hook into WooCommerce actions

**Frontend:**
1. `admin-spa/src/routes/ActivityLog/index.tsx` - Activity log page
2. `admin-spa/src/routes/ActivityLog/ActivityItem.tsx` - Single activity
3. `admin-spa/src/routes/ActivityLog/Filters.tsx` - Filter UI

---

## 3. Dynamic Push Notification URLs

### Current State
- Global URL: `/wp-admin/admin.php?page=woonoow#/orders`
- All notifications go to same page

### Strategy: Event-Specific Deep Links

### URL Templates

```php
$url_templates = [
    // Orders
    'order_placed'      => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
    'order_processing'  => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
    'order_completed'   => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
    'order_cancelled'   => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
    'order_refunded'    => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
    
    // Products
    'low_stock'         => '/wp-admin/admin.php?page=woonoow#/products/{product_id}',
    'out_of_stock'      => '/wp-admin/admin.php?page=woonoow#/products/{product_id}',
    
    // Customers
    'new_customer'      => '/wp-admin/admin.php?page=woonoow#/customers/{customer_id}',
    'customer_note'     => '/wp-admin/admin.php?page=woonoow#/orders/{order_id}',
];
```

### Template Variables

**Available Variables:**
- `{order_id}` - Order ID
- `{product_id}` - Product ID
- `{customer_id}` - Customer ID
- `{user_id}` - User ID
- `{site_url}` - Site URL
- `{admin_url}` - Admin URL

### Implementation

**Backend:**
1. Add URL template field to push settings
2. Parse template variables when sending
3. Store parsed URL in notification metadata

**Frontend:**
1. Add URL template field to Templates page
2. Show available variables
3. Preview parsed URL

---

## 4. Rich Notification Content

### Event-Specific Icons

```php
$notification_icons = [
    'order_placed'      => '🛒',
    'order_processing'  => '⚙️',
    'order_completed'   => '✅',
    'order_cancelled'   => '❌',
    'order_refunded'    => '💰',
    'low_stock'         => '📦',
    'out_of_stock'      => '🚫',
    'new_customer'      => '👤',
    'customer_note'     => '💬',
];
```

### Event-Specific Images

**Order Notifications:**
- Show first product image
- Fallback to store logo

**Product Notifications:**
- Show product image
- Fallback to placeholder

**Customer Notifications:**
- Show customer avatar (Gravatar)
- Fallback to default avatar

### Rich Content Structure

```json
{
    "title": "New Order #1234",
    "body": "John Doe ordered 2 items (Rp137.000)",
    "icon": "🛒",
    "image": "https://example.com/product.jpg",
    "badge": "https://example.com/logo.png",
    "data": {
        "url": "/wp-admin/admin.php?page=woonoow#/orders/1234",
        "order_id": 1234,
        "customer_name": "John Doe",
        "total": 137000
    },
    "actions": [
        {
            "action": "view",
            "title": "View Order",
            "icon": "👁️"
        },
        {
            "action": "mark_processing",
            "title": "Mark Processing",
            "icon": "⚙️"
        }
    ]
}
```
