# Real-Time Consultation Status Updates - Implementation Complete

## ✅ What's Been Implemented

### 1. **Customer Dashboard Real-Time Updates** ✨
- **File**: [customer-dashboard.php](customer-dashboard.php)
- **Features**:
  - Consultation cards now display with status badges (pending, approved, declined, scheduled, completed)
  - JavaScript polling every 5 seconds automatically checks for status changes
  - Status badges animate when they change
  - Toast notifications appear when consultant status updates
  - Color-coded badges:
    - 🟡 Pending (yellow)
    - 🟢 Approved (green)
    - 🔴 Declined (red)
    - 🔵 Scheduled (blue)

### 2. **New API Endpoint**
- **File**: [api/get-consultation-status.php](api/get-consultation-status.php)
- **Purpose**: Fetches current consultation statuses for authenticated user
- **Response Format**:
```json
{
  "success": true,
  "consultations": [
    {
      "id": 1,
      "consultation_type": "interior_design",
      "status": "approved",
      "budget_range": "50000-100000",
      "preferred_date": "2024-01-15",
      "created_at": "2024-01-10 10:30:00",
      "updated_at": "2024-01-11 14:25:00"
    }
  ],
  "timestamp": "2024-01-11 14:45:00"
}
```

### 3. **Database Updates**
- **Approve endpoint** ([api/approve-consultation.php](api/approve-consultation.php)):
  - Updated to set `updated_at = NOW()` when approving
  - Respects the email toggle flag
  
- **Decline endpoint** ([api/decline-consultation.php](api/decline-consultation.php)):
  - Updated to set `updated_at = NOW()` when declining
  - Respects the email toggle flag

## 🔄 How the Real-Time Updates Work

### Flow Diagram
```
Admin Dashboard (approves consultation)
         ↓
/api/approve-consultation.php
         ↓
Database UPDATE: status = 'approved', updated_at = NOW()
         ↓
Customer Dashboard (running polling)
         ↓
/api/get-consultation-status.php (checks every 5 seconds)
         ↓
JavaScript compares old status with new status
         ↓
If changed: Update badge, show animation, notify user
         ↓
Customer sees "Approved" status instantly (within 5 seconds)
```

## 📝 How to Use / Test

### For Customers:
1. Open [customer-dashboard.php](customer-dashboard.php)
2. Go to "Your Consultations" tab
3. View your consultation request with its status
4. **Keep the page open** - it will auto-refresh every 5 seconds
5. When admin approves/declines, you'll see:
   - Status badge changes color and animates
   - Toast notification appears at top
   - No page reload needed!

### For Admins:
1. Open [admin-dashboard.php](admin-dashboard.php)
2. Go to Consultations section
3. Toggle "Send Email on Action" checkbox (optional)
4. Click "Approve" or "Decline" button
5. Database updates immediately with new status
6. Customer sees the change within 5 seconds

## 🎨 Frontend Implementation Details

### JavaScript Polling Function
```javascript
// Starts every 5 seconds
startConsultationPolling() → fetchConsultationUpdates()
  ↓
/api/get-consultation-status.php
  ↓
updateConsultationDisplay() - Compares new status with old
  ↓
If status changed:
  - Update badge class
  - Play pulse animation
  - Show notification toast
```

### CSS Animations
- **Pulse Animation**: Status badge scales when status changes
- **Slide-In Animation**: Notification toast slides in from top
- **Auto-dismiss**: Notifications disappear after 5 seconds

## 🔐 Security Features

- ✅ Session authentication required (`$_SESSION['user_id']`)
- ✅ User can only see their own consultations (filtered by email)
- ✅ Admin-only actions (approve/decline) require admin role
- ✅ Timestamps track when status changes
- ✅ Email toggle controlled by admin only

## 📊 Database Schema

### Consultations Table (Updated)
```sql
- id (int, primary key)
- email (varchar)
- consultation_type (varchar)
- status (enum: pending, verified, scheduled, completed, cancelled, approved, declined)
- preferred_date (date)
- budget_range (varchar)
- created_at (timestamp)
- updated_at (timestamp) ← Now updated when status changes
```

## 🚀 Performance Considerations

- **Polling Interval**: 5 seconds (configurable in [customer-dashboard.php](customer-dashboard.php) line ~1442)
- **Network Load**: Minimal JSON responses, only includes needed fields
- **Database Queries**: Simple indexed queries on consultations table
- **Frontend**: Efficient DOM updates only when status changes
- **Auto-cleanup**: Polling stops if page becomes inactive (can be enhanced with Page Visibility API)

## 📋 Files Modified

1. **[customer-dashboard.php](customer-dashboard.php)** - Added polling and animation
2. **[api/approve-consultation.php](api/approve-consultation.php)** - Added updated_at timestamp
3. **[api/decline-consultation.php](api/decline-consultation.php)** - Added updated_at timestamp

## 📁 Files Created

1. **[api/get-consultation-status.php](api/get-consultation-status.php)** - New polling endpoint

## ✨ Enhanced Features

### Status Badge Colors
```css
.badge-pending      → Yellow (#fff3cd)
.badge-approved     → Green (#d4edda)
.badge-declined     → Red (#f8d7da)
.badge-scheduled    → Blue (#cfe2ff)
.badge-completed    → Green (#d4edda)
```

### Notification System
- Toast notifications appear when status changes
- Auto-dismiss after 5 seconds
- Shows consultation type and new status
- Smooth slide-in animation

## 🔄 Polling Configuration

To adjust polling interval, edit [customer-dashboard.php](customer-dashboard.php):
```javascript
// Line ~1442
consultationPollingInterval = setInterval(function() {
    fetchConsultationUpdates();
}, 5000);  // Change 5000 to desired milliseconds
```

**Recommended values:**
- 3000ms = Very responsive (high network load)
- 5000ms = Good balance (current default)
- 10000ms = Less responsive (lower network load)
