# Claude Memory - BlackMural Bulk SMS Frontend Development

## Project Overview
Comprehensive frontend development for BlackMural Bulk SMS platform with multi-tenant architecture (SuperAdmin → Admins → Clients → Users). Built using SneatDashboard theme with Bootstrap 5 integration.

## Completed Work

### 1. Dashboard Creation
- **SuperAdmin Dashboard**: Complete interface using agent-sneat-frontend-builder
- **Admin Dashboard**: Full dashboard following forms.md specifications
- **Client Dashboard**: Fixed existing Gemini-created files, completed 19 missing files

### 2. Authentication & Session Management
- Fixed login system field mismatches (email vs username)
- Updated header.php files for proper session management
- Enhanced error message handling across login forms
- Fixed session variable assignments in login models

### 3. Database Operations Standardization
- Updated all queries to use `select_rows()` function per db_operations.md
- Fixed array to JSON conversion for variables fields
- Corrected `security_get()` usage patterns (removed $_GET parameter passing)
- Used agent-mysql-schema-builder for database structure updates

### 4. Field Name Corrections
- Fixed sender_id_id field references in assignment queries
- Removed non-existent fields (price, sms_count, validity_days from packages)
- Updated admin/reports.php to use existing database fields
- Corrected delivery_status to status in campaign performance

### 5. Message Personalization
- Implemented variable replacement in bulk SMS (standard + custom JSON fields)
- Fixed SMS template variables from first_name/last_name to single 'name'
- Enhanced template form with proper variables[] array handling

### 6. UI/UX Improvements
- Added JavaScript to clear GET parameters after page load
- Updated sidebar navigation with missing menu items
- Fixed bulk upload field name mismatch (csv_file vs contacts_file)
- Added campaign selection interface in performance view

## Recent Fixes

### client/campaign_performance.php
- Added campaign selection when no campaign_id provided
- Fixed database field references (delivery_status → status)
- Removed non-existent api_response field and related modal
- Updated to use select_rows() with proper foreach iteration

### admin/reports.php
- Removed price field references from packages table
- Updated revenue calculation to use package assignments count
- Fixed queries to match actual database structure

### Multiple Admin Files
- Fixed security_get() usage across 15 files
- Updated field references to match database schema
- Standardized error handling and user feedback

## Technical Patterns Established

### Database Operations
```php
// Standard pattern for data retrieval
$result = select_rows("SELECT * FROM table WHERE condition");

// Array to JSON conversion for variables
$variables = array_filter($_POST['variables'] ?? []);
$data['variables'] = !empty($variables) ? json_encode($variables) : null;

// Proper security_get usage
$field_value = security_get('field_name'); // NOT security_get($_GET['field_name'])
```

### Message Personalization
```php
// Standard field replacement
$personalized_message = str_replace('{name}', $contact['name'] ?? '', $message);

// Custom fields from JSON
$custom_fields = json_decode($contact['custom_fields'], true);
foreach ($custom_fields as $key => $value) {
    $personalized_message = str_replace('{' . $key . '}', $value ?? '', $personalized_message);
}
```

### Form Validation & Feedback
```php
// Error handling pattern
<?php if ($error): ?>
<div class="alert alert-danger alert-dismissible" role="alert">
    <?= htmlspecialchars($error) ?>
    <button type="button" class="btn-close" data-bs-dismiss="alert"></button>
</div>
<?php endif; ?>
```
