# Records Auditing & Analytics Summary

## Overview
This document explains the individual user record auditing and analytics implementation across different dashboards.

---

## 📊 Current Implementation

### 1. **User Dashboard** ([public/dashboard.php](public/dashboard.php))
**✅ FULLY IMPLEMENTED - Individual User Analytics**

**Features:**
- **Personal Statistics**: Shows only the logged-in user's data
  - Total forms created by user
  - Completed forms by user
  - Draft forms by user
  - Today's forms by user
  - This week's forms by user
  - This month's forms by user

- **Charts & Analytics**:
  - Weekly Activity Trend (last 7 days) - User-specific
  - Form Status Distribution (Pie chart) - User-specific
  - Monthly Performance (last 12 months) - User-specific

- **Recent Activity**: Shows user's last 5 forms

**SQL Filtering**:
```php
WHERE created_by = ? // User ID
```

**Location**: Lines 21-76 implement user-specific filtering

---

### 2. **Records Page** ([public/records.php](public/records.php))
**✅ NOW FIXED - Role-Based Record Access**

**Before Fix (SECURITY ISSUE):**
- ❌ Showed ALL records from ALL users to everyone
- ❌ Privacy/security violation
- ❌ No user-specific filtering

**After Fix (SECURE):**
- ✅ **Regular Users**: See ONLY their own records
- ✅ **Admins**: See ALL records from all users
- ✅ Statistics filtered by user role
- ✅ Clear header indicating user vs admin view

**Implementation:**
```php
// Line 38-41
if (!is_admin()) {
    $where_conditions[] = "created_by = ?";
    $params[] = $current_user['id'];
}
```

**Features by Role:**

**For Regular Users:**
- View only personal records
- Personal statistics (completed, today, this week)
- Search/filter within own records only
- Export only own records to CSV
- Header: "View and manage your personal records"

**For Admins:**
- View ALL records from ALL users
- System-wide statistics
- Search/filter across all records
- Export all records to CSV
- Header: "View and manage all records from all users"

---

### 3. **Admin Dashboard** ([admin/dashboard.php](admin/dashboard.php))
**✅ CORRECTLY IMPLEMENTED - System-Wide Analytics**

**Features:**
- **System-Wide Statistics**:
  - Total forms (all users)
  - Today's forms (all users)
  - Active users count

- **Recent Forms Table**: Shows last 10 forms from all users
- **No User Filtering**: Intentional - admins need to see everything

**Purpose**: Administrative oversight of the entire system

## 🔒 Security & Privacy

### Access Control
| Page | Regular User Access | Admin Access |
|------|-------------------|--------------|
| `public/dashboard.php` | ✅ Own data only | ✅ Own data only |
| `public/records.php` | ✅ Own records only | ✅ ALL records |
| `admin/dashboard.php` | ❌ No access | ✅ ALL data |

### Data Isolation
- **Regular Users**:
  - Cannot see other users' records
  - All queries filtered by `created_by = current_user_id`
  - Statistics computed only from their data

- **Admins**:
  - Can see all records (needed for oversight)
  - System-wide analytics
  - Can manage all users' data

## 🔧 Technical Implementation

### User Filtering Pattern
```php
// Check if admin
if (is_admin()) {
    // No filter - show all records
    $sql = "SELECT * FROM prehospital_forms";
    $stmt = db_query($sql);
} else {
    // Filter by current user
    $sql = "SELECT * FROM prehospital_forms WHERE created_by = ?";
    $stmt = db_query($sql, [$current_user['id']]);
}
```

### Statistics Pattern
```php
if (is_admin()) {
    $sql = "SELECT COUNT(*) FROM prehospital_forms";
    $stmt = db_query($sql);
} else {
    $sql = "SELECT COUNT(*) FROM prehospital_forms WHERE created_by = ?";
    $stmt = db_query($sql, [$current_user['id']]);
}
```
