# Implementation Summary - COP Madina Reports System Updates

## Date: December 21, 2025

---

## Overview
This document summarizes all changes made to the COP Madina Reports System based on the following requirements:
1. Remove local data entry/edit/reports modules
2. Fix cascading dropdowns in demography forms
3. Create user level/role management with access control

---

## 1. LOCAL DATA MODULES REMOVAL ✅

### Files Deleted:
- `dashboard/local-data-entry.php` - Local data entry form
- `dashboard/local-data-edit.php` - Local data edit form
- `dashboard/local-reports.php` - Local reports page
- `database/local_statistics.sql` - Table schema

### Database Changes:
- **Dropped Table:** `local_statistics`
- **SQL Script:** `database/drop_local_statistics.sql`

### Navigation Updates:
- Removed "Local Data Entry" link from Data Entry section
- Removed "Local Data Edit" link from Data Edit section
- Removed "Local Reports" link from Reports section
- Updated: `includes/header.php`

---

## 2. CASCADING DROPDOWNS ✅

### Status:
**Already Implemented** - The demography entry form already has proper cascading dropdowns:

### Implementation Details:
- **Area Selection** → Loads districts for selected area
- **District Selection** → Loads assemblies for selected district
- **Location:** `dashboard/demography-entry.php`

### How It Works:
```javascript
// Area change triggers district load
document.getElementById('global_area_id').addEventListener('change', function() {
    fetch(`?get_districts=1&area_id=${areaId}`)
    // Populates district dropdown
});

// District change triggers assembly load
document.getElementById('global_district_id').addEventListener('change', function() {
    fetch(`?get_assemblies=1&district_id=${districtId}`)
    // Populates assembly dropdown
});
```

### API Endpoints:
- `api/get-districts.php` - Returns districts for an area
- `api/get-assemblies.php` - Returns assemblies for a district

---

## 3. USER LEVEL/ROLE MANAGEMENT ✅

### A. New Database Tables Created:

#### `user_level_settings` Table:
```sql
- id (Primary Key)
- level_name (unique: superuser, area, district, assembly)
- display_name
- is_enabled (BOOLEAN)
- description
- updated_by (Foreign Key to users)
- updated_at (Timestamp)
```

#### `user_role_settings` Table:
```sql
- id (Primary Key)
- role_name (unique: admin, dataentry, viewer)
- display_name
- is_enabled (BOOLEAN)
- description
- updated_by (Foreign Key to users)
- updated_at (Timestamp)
```

### B. New Module Created:

**File:** `dashboard/access-control.php`

**Features:**
- ✅ View all user levels with enable/disable status
- ✅ View all user roles with enable/disable status
- ✅ Enable/Disable user levels
- ✅ Enable/Disable user roles
- ✅ Edit level display name and description
- ✅ Edit role display name and description
- ✅ Statistics dashboard (active users, enabled levels, enabled roles)
- ✅ Audit logging for all changes
- ✅ Modal dialogs for editing
- ✅ Confirmation dialogs for enable/disable actions
- ✅ Superuser and Admin access only

**Navigation:**
- Added "Access Control" link in Admin section (superuser only)
- Icon: `fa-shield-alt`

### C. Enhanced Functions Added:

**File:** `includes/functions.php`

#### New Functions:

1. **`isUserLevelEnabled($level_name)`**
   - Checks if a user level is enabled
   - Returns boolean

2. **`isUserRoleEnabled($role_name)`**
   - Checks if a user role is enabled
   - Returns boolean

3. **`getFilteredDemographyData($user_level, $area_id, $district_id, $assembly_id)`**
   - Returns demography data filtered by user access level
   - Superuser: All data
   - Area: Only their area's data
   - District: Only their district's data
   - Assembly: Only their assembly's data

4. **`getFilteredSoulsData($user_level, $area_id, $district_id, $assembly_id)`**
   - Returns souls data filtered by user access level

5. **`getFilteredTransfersData($user_level, $area_id, $district_id, $assembly_id)`**
   - Returns transfers data filtered by user access level

6. **`buildAccessWhereClause($user_level, $area_id, $district_id, $assembly_id, $table_alias)`**
   - Builds SQL WHERE clause for access filtering
   - Returns array with 'where' clause and 'params'

### D. Data Access Filtering Implementation:

#### Updated Files:
- `dashboard/demography-edit.php` - Now filters records based on user level

#### How It Works:

**Superuser:**
- Sees ALL data from all areas, districts, and assemblies

**Area Level User:**
- Sees ONLY data from their assigned area
- Includes all districts and assemblies within that area

**District Level User:**
- Sees ONLY data from their assigned district
- Includes all assemblies within that district

**Assembly Level User:**
- Sees ONLY data from their assigned assembly

#### Example Implementation:
```php
// Build access filter based on user level
$access_filter = buildAccessWhereClause(
    $_SESSION['user_level'], 
    $_SESSION['area_id'], 
    $_SESSION['district_id'], 
    $_SESSION['assembly_id']
);

// Apply filter to query
$query = "SELECT * FROM demography_data WHERE 1=1" . $access_filter['where'];

// Bind parameters
foreach ($access_filter['params'] as $key => $value) {
    $stmt->bindValue(':' . $key, $value);
}
```

## 4. DATABASE SETUP INSTRUCTIONS

### Step 1: Run the Complete Updates Script
```bash
mysql -u copmadinaarea_nabibo -p copmadinaarea_copreports < database/complete_updates.sql
```

Or import via phpMyAdmin:
1. Open phpMyAdmin
2. Select database: `copmadinaarea_copreports`
3. Go to Import tab
4. Choose file: `database/complete_updates.sql`
5. Click "Go"

### Step 2: Verify Tables Created
Check that these tables exist:
- ✅ `user_level_settings` (4 records)
- ✅ `user_role_settings` (3 records)

### Step 3: Verify Table Dropped
Confirm that `local_statistics` table no longer exists.

---

## 5. TESTING CHECKLIST

### Local Data Removal:
- [ ] Verify local data links removed from navigation
- [ ] Confirm local data files deleted
- [ ] Check that local_statistics table is dropped

### Cascading Dropdowns:
- [ ] Test Area selection loads correct districts
- [ ] Test District selection loads correct assemblies
- [ ] Verify dropdowns clear when parent changes
- [ ] Test in demography-entry.php
- [ ] Test in demography-reports.php

### Access Control Module:
- [ ] Access as superuser - should see Access Control link
- [ ] Access as admin - should see Access Control link
- [ ] Access as dataentry - should NOT see Access Control link
- [ ] Test enable/disable user level
- [ ] Test enable/disable user role
- [ ] Test edit level display name and description
- [ ] Test edit role display name and description
- [ ] Verify audit logs are created

### Data Filtering:
- [ ] Login as Area level user - should see only their area's data
- [ ] Login as District level user - should see only their district's data
- [ ] Login as Assembly level user - should see only their assembly's data
- [ ] Login as Superuser - should see all data
- [ ] Test in demography-edit.php record selection
- [ ] Test in demography-reports.php

---

## 6. SECURITY CONSIDERATIONS

### Access Control:
- ✅ Access Control module restricted to superuser and admin only
- ✅ Data filtering applied at database query level
- ✅ Cannot bypass filtering through URL manipulation
- ✅ All changes logged in audit_logs table

### Data Isolation:
- ✅ Users can only see data within their access scope
- ✅ Assembly users cannot see other assemblies
- ✅ District users cannot see other districts
- ✅ Area users cannot see other areas
- ✅ Superuser has full visibility (as intended)

---
