/**
 * Integration Guide: Update Navigation to Use Real-Time Dashboard
 * 
 * This file shows how to integrate the new real-time staff dashboard
 * into your existing navigation and templates.
 */

// ============================================================
// STEP 1: Update Staff Login Redirect
// ============================================================
// In: staff-login.php
// After successful authentication, change:

// OLD:
// header('Location: dashboards/staff-dashboard.php');

// NEW:
// header('Location: dashboards/staff-dashboard-realtime.php');


// ============================================================
// STEP 2: Update Navigation Links
// ============================================================
// In: header.php or nav template
// Update any staff dashboard links:

// OLD:
// <a href="dashboards/staff-dashboard.php">Staff Dashboard</a>

// NEW:
// <a href="dashboards/staff-dashboard-realtime.php">Staff Dashboard</a>


// ============================================================
// STEP 3: Update Menu Items
// ============================================================
// In: navigation menus or sidebars
// Change dashboard links:

// OLD:
// $dashboardURL = 'dashboards/staff-dashboard.php';

// NEW:
// $dashboardURL = 'dashboards/staff-dashboard-realtime.php';


// ============================================================
// STEP 4: Optional - Create Redirect Page
// ============================================================
// If you want to keep old dashboard name but redirect:
// Create: dashboards/staff-dashboard.php
// With content:

?>
<?php
// Redirect to real-time dashboard
header('Location: staff-dashboard-realtime.php', true, 301);
exit;
?>
<?php
// ============================================================


// ============================================================
// STEP 5: Verify Access in config.php (Already Done)
// ============================================================
// Make sure config.php has:
// - inquiries table (existing)
// - appointments table (existing)  
// - realtime_updates table (auto-created)
// - Session management for staff
//
// These are all auto-created on first access!


// ============================================================
// STEP 6: Test the Integration
// ============================================================
// After updating links, test:

// 1. Login as staff user
// 2. Should redirect to real-time dashboard
// 3. Dashboard should load in < 2 seconds
// 4. Real-time data should appear within 5 seconds
// 5. Clicking Approve/Decline should work instantly

// ============================================================
// STEP 7: Debug If Needed
// ============================================================
// If dashboard doesn't load, check:

// 1. Check browser console (F12 > Console tab)
//    - Should see: "Real-Time Staff Dashboard Started"
//    - No red error messages

// 2. Check Network tab (F12 > Network tab)
//    - All API calls should return 200 OK
//    - Check for failed requests

// 3. Check database (phpMyAdmin)
//    - inquiries table should exist
//    - appointments table should exist
//    - realtime_updates table auto-created

// 4. Check staff user exists
//    - users table should have role='staff'
//    - $_SESSION['user_id'] should be set
//    - $_SESSION['role'] should be 'staff'

<?php
/**

<?php
/**
 * This is not recommended because:
 * - Less responsive
 * - Polling conflicts
