# KSO Chandigarh Management System
## Production Deployment Guide - Notification System Upgrade

### 🚀 **LIVE HOSTING DEPLOYMENT PLAN**

---

## 📋 **Pre-Deployment Checklist**

### 1. **Backup Your Database** (CRITICAL!)
```sql
-- Create a complete backup before any changes
mysqldump -u [username] -p [database_name] > kso_backup_$(date +%Y%m%d_%H%M%S).sql

-- Alternative: Use your hosting control panel backup feature
-- cPanel: File Manager → Database Backups
-- Plesk: Databases → Export Dump
```

### 2. **Check Current Database State**
- Upload `admin/notifications/db_check.php` to your server
- Visit: `yoursite.com/admin/notifications/db_check.php`
- Verify current notification table structure

---

## 🔧 **Deployment Steps**

### **STEP 1: Upload New Files**
Upload these new files to your hosting:
```
/admin/notifications/
├── api.php              ← Real-time notification API
├── manage.php           ← Admin management interface
├── test.php             ← Testing interface
├── setup.php            ← Setup interface
├── setup_handler.php    ← Setup logic
├── db_check.php         ← Database checker
└── db_check.html        ← Visual database checker

/js/
└── kso-notifications.js ← Notification system JavaScript

/css/
└── kso-notifications.css ← Notification system styles

/includes/
├── admin-notifications.php ← Admin integration helper
└── member-notifications.php ← Member integration helper

/sql/
└── notification_migration.sql ← Safe migration script
```

### **STEP 2: Database Migration** (Safe Upgrade)
```sql
-- Option A: Via phpMyAdmin/hosting control panel
-- 1. Login to phpMyAdmin
-- 2. Select your database
-- 3. Go to "Import" tab
-- 4. Upload notification_migration.sql
-- 5. Execute

-- Option B: Via command line (if available)
mysql -u [username] -p [database_name] < notification_migration.sql
```

### **STEP 3: File Integration Updates**
The migration script automatically handles database changes, but you need to update these existing files:

#### A. **Admin Dashboard Integration**
Update your main admin dashboard file to include notifications:
```php
<!-- Add to <head> section -->
<link href="<?php echo BASE_URL; ?>/css/kso-notifications.css" rel="stylesheet">

<!-- Add before closing </body> -->
<script src="<?php echo BASE_URL; ?>/js/kso-notifications.js"></script>
<script>
document.addEventListener('DOMContentLoaded', function() {
    if (typeof KSONotificationManager !== 'undefined') {
        window.notificationManager = new KSONotificationManager({
            apiUrl: '<?php echo BASE_URL; ?>/admin/notifications/api.php',
            soundEnabled: true,
            browserNotificationsEnabled: true,
            userRole: 'admin',
            userId: <?php echo get_current_user_id(); ?>
        });
    }
});
</script>
```

#### B. **Member Dashboard Integration**
Update your member dashboard similarly:
```php
<!-- Add to <head> section -->
<link href="../css/kso-notifications.css" rel="stylesheet">

<!-- Add before closing </body> -->
<script src="../js/kso-notifications.js"></script>
<script>
document.addEventListener('DOMContentLoaded', function() {
    if (typeof KSONotificationManager !== 'undefined') {
        window.notificationManager = new KSONotificationManager({
            apiUrl: '../admin/notifications/api.php',
            soundEnabled: true,
            browserNotificationsEnabled: true,
            userRole: 'member',
            userId: <?php echo $_SESSION['member_id'] ?? 0; ?>
        });
    }
});
</script>
```

### **STEP 4: Test the System**
1. Visit: `yoursite.com/admin/notifications/db_check.html`
2. Verify all tables are created
3. Visit: `yoursite.com/admin/notifications/test.php`
4. Test notification functionality
5. Visit: `yoursite.com/admin/notifications/manage.php`
6. Send test notifications

---

## ⚠️ **PRODUCTION SAFETY MEASURES**

### **Maintenance Mode** (Recommended)
```php
// Add to top of index.php temporarily
if (!isset($_SESSION['admin_maintenance_bypass'])) {
    die('System under maintenance. Please try again in a few minutes.');
}
```

### **Rollback Plan**
```sql
-- If something goes wrong, restore from backup:
mysql -u [username] -p [database_name] < kso_backup_YYYYMMDD_HHMMSS.sql

-- Remove new notification files:
rm -rf admin/notifications/
rm js/kso-notifications.js
rm css/kso-notifications.css
```

### **Gradual Rollout**
1. Deploy during low-traffic hours
2. Test with admin accounts first
3. Monitor error logs
4. Enable for all users once stable

---

## 🔍 **Post-Deployment Verification**

### **Database Checks:**
```sql
-- Verify notification tables exist
SHOW TABLES LIKE 'notification%';

-- Check sample data
SELECT COUNT(*) FROM notifications;
SELECT COUNT(*) FROM notification_settings;

-- Verify user settings created
SELECT user_type, COUNT(*) FROM notification_settings GROUP BY user_type;
```

### **File Checks:**
- [ ] Notification bell appears in admin/member topbars
- [ ] No JavaScript errors in browser console
- [ ] CSS styles loading correctly
- [ ] API endpoints responding (test with browser dev tools)

### **Functionality Tests:**
- [ ] Send test notification from manage.php
- [ ] Verify real-time delivery
- [ ] Test browser notifications
- [ ] Check sound notifications
- [ ] Verify read/unread status

---

## 📱 **Browser Compatibility**

### **Supported Features:**
- **Chrome/Edge**: Full support (SSE, notifications, sounds)
- **Firefox**: Full support (SSE, notifications, sounds)
- **Safari**: Limited (polling fallback, basic notifications)
- **Mobile**: Responsive design, touch-friendly

### **Fallback Mechanisms:**
- Server-Sent Events → Polling fallback
- Browser notifications → Toast notifications
- Sound notifications → Visual indicators

---

## 🔧 **Configuration Options**

### **Environment Variables** (add to config/init.php):
```php
// Notification system settings
define('NOTIFICATION_POLLING_INTERVAL', 5000); // 5 seconds
define('NOTIFICATION_MAX_PER_PAGE', 20);
define('NOTIFICATION_SOUND_ENABLED', true);
define('NOTIFICATION_CLEANUP_DAYS', 30);
```

### **Server Requirements:**
- PHP 7.4+ (JSON support)
- MySQL 5.7+ (JSON column support)
- Apache/Nginx with mod_rewrite
- HTTPS recommended for browser notifications

---

## 🚨 **Common Issues & Solutions**

### **Issue: Notifications not loading**
```javascript
// Check browser console for errors
// Verify API endpoint is accessible
fetch('/admin/notifications/api.php?action=fetch')
  .then(r => r.json())
  .then(console.log)
  .catch(console.error);
```

### **Issue: Browser notifications not working**
- Ensure HTTPS is enabled
- Check browser notification permissions
- Verify domain is not blocked

### **Issue: Database connection errors**
- Verify database credentials in config/database.php
- Check hosting provider MySQL version compatibility
- Ensure sufficient database permissions

---

## 📞 **Support & Monitoring**

### **Error Monitoring:**
- Check server error logs: `/var/log/apache2/error.log`
- Monitor PHP errors in hosting control panel
- Set up database query logging

### **Performance Monitoring:**
- Monitor SSE connection count
- Track notification delivery success rate
- Monitor database query performance
