# File Upload Functionality - Fixes Applied

## Issues Found & Fixed

### 1. **HTML Form - Missing Multipart Encoding** ✅ FIXED
**Problem**: Form was missing `enctype="multipart/form-data"` attribute
**Impact**: Files could not be properly uploaded to server
**Fix Applied**: Added `enctype="multipart/form-data"` to `<form id="reportForm">`

### 2. **Form Fields - Missing Name Attributes** ✅ FIXED
**Problem**: Data Compromised, Financial Impact, and Business Impact fields had no `name` attributes
**Impact**: Form data for these fields were not being submitted
**Fix Applied**:
- Added `name="dataCompromised"` to data compromised select
- Added `name="financialImpact"` to financial impact select
- Added `name="businessImpact"` and `value` attributes to all 4 checkboxes

### 3. **Database Table Names - Incorrect References** ✅ FIXED
**Problem**: 
- Using non-existent table `incident_files` instead of `evidence_files`
- Using non-existent table `incident_activity_log` instead of `incident_activities`

**Fix Applied**:
- Changed: `INSERT INTO incident_files` → `INSERT INTO evidence_files`
- Changed: `INSERT INTO incident_activity_log` → `INSERT INTO incident_activities`
- Updated column names: `activity_description` instead of `description`

### 4. **Upload Directory Path - Incorrect** ✅ FIXED
**Problem**: Path was `../images/uploads/incidents/` (relative, unreliable)
**Impact**: Directory may not be created in the correct location
**Fix Applied**: 
- Changed to: `__DIR__ . '/../uploads/incidents/'` (absolute path)
- Creates directory at: `/htdocs/bci/uploads/incidents/`

### 5. **File Error Handling - Incomplete** ✅ FIXED
**Problem**: 
- Used simple `UPLOAD_ERR_OK` check without handling other error codes
- Errors were added to `$response['errors']` stopping all uploads
- No distinction between fatal errors and file-specific errors

**Fix Applied**:
- Created separate `$fileUploadErrors[]` array for file upload issues
- Added handlers for all PHP upload error codes:
  - `UPLOAD_ERR_INI_SIZE` - exceeds php.ini limit
  - `UPLOAD_ERR_FORM_SIZE` - exceeds form limit
  - `UPLOAD_ERR_PARTIAL` - partial upload
  - `UPLOAD_ERR_NO_TMP_DIR` - temp directory missing
  - `UPLOAD_ERR_CANT_WRITE` - write failure
  - `UPLOAD_ERR_EXTENSION` - blocked by extension
- Empty file slots are now properly skipped
- File upload errors don't block incident report submission

### 6. **File Validation - Missing MIME Type** ✅ FIXED
**Problem**: Variable name was `$fileType` but column is `mime_type`
**Fix Applied**: Changed variable to `$fileMimeType` for consistency

### 7. **File Path Storage - Missing Hash** ✅ FIXED
**Problem**: 
- Not storing file path or hash in database
- Cannot verify file integrity

**Fix Applied**:
- Added `hash_sha256` calculation using `hash_file('sha256', ...)`
- Store relative file path: `/uploads/incidents/[filename]`
- Added to database insert: `file_path` and `hash_sha256`

### 8. **Response - Missing File Upload Feedback** ✅ FIXED
**Problem**: User doesn't know how many files uploaded or if there were file errors
**Fix Applied**: 
- Added to JSON response:
  - `uploadedFiles`: Count of successfully uploaded files
  - `uploadErrors`: Array of file-specific error messages

### 9. **MIME Type Validation** ✅ VERIFIED
**Status**: Already correct in form
- Allowed types: JPEG, PNG, PDF, TXT, ZIP
- Proper validation using `mime_content_type()` function

### 10. **AJAX FormData** ✅ VERIFIED
**Status**: Already properly implemented
- Using `new FormData(reportForm)` - automatically includes file uploads
- Properly handles multipart form data

## Database Query Testing

```sql
-- Check uploaded incidents
SELECT id, reference_id, reporter_full_name, priority_level, status 
FROM incident_reports 
ORDER BY submission_date DESC 
LIMIT 10;

-- Check uploaded files
SELECT ef.*, ir.reference_id 
FROM evidence_files ef
JOIN incident_reports ir ON ef.incident_id = ir.id
ORDER BY ef.uploaded_at DESC;

-- Verify file integrity with hash
SELECT original_filename, hash_sha256, file_size, uploaded_at 
FROM evidence_files 
WHERE incident_id = [incident_id];
```
