## 🚀 How to Install

### Step 1: Run Installation
```
Visit: http://localhost/copmadinaarea/install_module_management.php
```

**What it does:**
1. Creates database tables
2. Migrates existing modules
3. Sets up access permissions
4. Adds Module Management module itself

### Step 2: Access the Module
After installation:
1. Check your sidebar menu
2. Navigate to: **System → Module Management**
3. You'll see the module management dashboard

---

## 💡 How to Use

### Control Module Access
For any module, you can toggle access for each level:

**Example 1: Hide "Member Accounts" from Assembly Admins**
```
1. Find "Member Accounts" row
2. Toggle OFF under "Assembly" column
3. Assembly admins no longer see this module
```

**Example 2: Enable "Events" for All Levels**
```
1. Find "Events" row
2. Ensure all 4 toggles are ON
3. All admin levels can access Events
```

**Example 3: Create District-Only Module**
```
1. Find the module
2. Set: Assembly OFF, District ON, Area ON, Superuser ON
3. Only District admins and above can access
```

### Activate/Deactivate Modules
Use the power button in Actions column:
- Deactivates module for ALL users
- Can be reactivated anytime
- Critical modules cannot be deactivated

---

## 🧪 Testing

### 1. Create Test Users
Use the existing `create_test_users.php`:
```
Creates 3 test accounts:
- assembly_admin (Password: Test@2025)
- district_admin (Password: Test@2025)
- area_admin (Password: Test@2025)
```

### 2. Test Access Control
```
1. As superuser: Disable "Events" for Assembly level
2. Log out
3. Log in as assembly_admin
4. Verify "Events" is NOT in sidebar
5. Log back in as superuser
6. Check audit log to confirm change
```

### 3. Test Sidebar Updates
```
1. Make module changes
2. Log out and back in
3. Sidebar automatically reflects new access
4. No code changes needed!
```

## 📊 Database Structure

### New Tables Created

**module_access_levels:**
```
- Tracks which access levels can see each module
- One row per module-level combination
- Includes who enabled it and when
```

**module_access_audit:**
```
- Logs all access control changes
- Shows who, what, when, why
- Action: enabled or disabled
- Never deleted (permanent history)
```

### Updated Table

**module_management:**
```
Added columns:
- is_system_critical (Boolean)
- category (VARCHAR)
```

---

## 🔐 Security Features

### What You CAN Do:
✅ Enable/disable modules for Assembly, District, Area admins  
✅ Deactivate non-critical modules  
✅ View complete audit trail  
✅ Organize modules by category  

### What You CANNOT Do:
❌ Disable critical modules (Dashboard, Settings, Users, Notifications)

## 📋 Module Categories

All modules are organized into categories:

4. **User Management** - User and account management

## 🔄 How It Works

### Before (Hardcoded):
```php
// Sidebar had hardcoded menu items
$menuStructure = [
    ['name' => 'Events', 'access' => 'viewer'],
    // Fixed in code
];
```

### After (Database-Driven):
```php
// Sidebar queries database
SELECT m.* FROM module_management m
LEFT JOIN module_access_levels mal ON m.id = mal.module_id
WHERE mal.access_level = 'assembly'
AND mal.is_enabled = 1
// Dynamic from database!
```

**Benefits:**
- No code changes to update menu
- Real-time access control
- Audit trail included
- Centralized management

## 🎯 Use Cases

### Scenario 1: Restrict Assembly Admins
```
Purpose: Assembly admins should only see basic features
Solution: Disable advanced modules for Assembly level
Example: Disable Users, Settings, Email Management
```

### Scenario 2: Gradual Feature Rollout
```
Purpose: Test new module with District admins first
Solution: Enable for District+ only, expand later
Example: New reporting feature
```

### Scenario 3: Organizational Hierarchy
```
Purpose: Match system access to church structure
Solution: Higher levels see more features
Example: Area admins manage multiple districts
```

## 🔍 Troubleshooting

**Problem:** Changes not showing  
**Solution:** User must log out and log back in

**Problem:** Cannot disable module  
**Solution:** It's a critical module - these cannot be disabled

**Problem:** Lost access to Module Management  
**Solution:** Only superusers can access - log in as superuser

**Problem:** Module not in list  
**Solution:** May need to add module to database first
