## Database Integration

The AdminLTE integration fully utilizes your existing database structure:

### Core Tables Used
- `members` - Member management with KSO ID auto-generation
- `admins` - Admin users with role-based permissions
- `dependents` - Family member management
- `events` - Event management and registrations
- `finance` - Payment and fee tracking
- `expenses` - Expense management
- `activity_logs` - System activity tracking
- `notifications` - System notifications

### New Features
- Auto-generated KSO IDs (KSOCHD001, KSOCHD002, etc.)
- Enhanced activity logging
- Real-time statistics
- Advanced search capabilities

## Admin Roles & Permissions

The system maintains your existing role hierarchy:

1. **President** (Level 9) - Full access to all features
2. **Vice President** (Level 8) - Member, event, finance management
3. **General Secretary** (Level 7) - Member and event management
4. **Finance Secretary** (Level 6) - Finance and reporting
5. **Assistant General Secretary** (Level 5) - Member and event support
6. **Secretaries** (Level 4) - Specialized access based on department

### Permission System
```php
// Check permissions in your pages
if (has_permission('manage_members')) {
    // Show member management features
}

if (has_permission('manage_finance')) {
    // Show finance features
}
```

## Using the New System

### 1. Migration Process

1. **Backup Current System**
   ```
   Visit: /admin/migrate-to-adminlte.php
   Execute each migration step safely
   ```

2. **Update Entry Points**
   - `/admin/index.php` → redirects to AdminLTE dashboard
   - `/admin/login.php` → preserved, new `/admin/login-adminlte.php` available

3. **Gradual Migration**
   - Both old and new systems can run simultaneously
   - Migrate individual pages gradually using the helper functions

### 2. Creating New Admin Pages

```php
<?php
require_once(__DIR__ . '/../../config/init.php');
require_admin();

$page_title = 'Your Page Title';

// Include AdminLTE header
include_once(__DIR__ . '/../templates/header.php');
include_once(__DIR__ . '/../templates/navbar.php');
include_once(__DIR__ . '/../templates/sidebar.php');
?>

<!-- Content Wrapper -->
<div class="content-wrapper">
    <!-- Content Header -->
    <div class="content-header">
        <div class="container-fluid">
            <div class="row mb-2">
                <div class="col-sm-6">
                    <h1><?php echo $page_title; ?></h1>
                </div>
                <div class="col-sm-6">
                    <ol class="breadcrumb float-sm-right">
                        <li class="breadcrumb-item"><a href="<?php echo ADMIN_URL; ?>">Home</a></li>
                        <li class="breadcrumb-item active"><?php echo $page_title; ?></li>
                    </ol>
                </div>
            </div>
        </div>
    </div>

    <!-- Main content -->
    <section class="content">
        <div class="container-fluid">
            <!-- Your content here -->
            <div class="card">
                <div class="card-header">
                    <h3 class="card-title">Card Title</h3>
                </div>
                <div class="card-body">
                    <!-- Your content -->
                </div>
            </div>
        </div>
    </section>
</div>

<?php include_once(__DIR__ . '/../templates/footer.php'); ?>
```

### 3. Migrating Existing Pages

For existing pages, use the helper functions:

```php
// At the top of existing pages
require_once(__DIR__ . '/adminlte-helper.php');

// Replace old header includes
// include_once('old-header.php');
include_adminlte_header('Page Title');

// Your existing content here

// Replace old footer includes  
// include_once('old-footer.php');
include_adminlte_footer();
```
