## 📊 Before vs After
|
||||
|
||||
| Metric | Before | After | Improvement |
|
||||
|--------|--------|-------|-------------|
|
||||
| **CSS Size** | ~200KB | ~9KB | **95% smaller** |
|

## 🎨 Design System
|
||||
|
||||
### Color Palette
|
||||
```css
|
||||
--color-primary: #c104fc /* Purple - main accent */
|
||||
--color-secondary: #4da870 /* Green - secondary accent */
|
||||
--color-text: #333 /* Dark gray - main text */
|
||||

|
||||
---
|
||||
|
||||
## 📞 Support
|
||||
|
||||
The new CSS maintains full compatibility with the existing HTML structure. All Bulma classes still work, but are now implemented with custom, lightweight CSS.
|
||||
|
||||
To revert to Bulma (not recommended):
|
||||
```html
|
||||
<!-- In apps/public/inc/header.php -->
|
||||
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bulma@0.9.4/css/bulma.min.css">
|
||||
```
|
||||
|
||||
But the custom CSS is faster, smaller, and fully customizable! 🎉

|
||||
- `LIENS`
|
||||

|
||||
|
||||
(These codes must match exactly what exists in the `ap_programs` table)
|
||||
|
||||
### Language Values
|
||||
Languages should be provided with capital first letter:
|
||||
- `Français`
|
||||
- `English`
|
||||
- `Nederlands`
|
||||
- etc.
|

### Format Values
|
||||
Common format values (case-insensitive, will be normalized):

|
||||
- `Video`
|
||||
- `Audio`
|
||||
- `Installation`
|
||||
- `Web`
|
||||
- etc.
|
||||
|
||||
## Import Behavior
|
||||
|
||||
### Row Processing
|
||||
1. Empty rows (no title and no identifier) are skipped
|
||||
2. Each row is processed in a transaction
|
||||
3. If a row fails, it is skipped and logged, but processing continues
|
||||
|
||||
### Data Validation
|
||||
- If title or year is missing, the row is rejected
|
||||
- Invalid orientation codes result in no orientation being set (null)
|
||||
- Invalid AP codes result in no AP program being set (null)
|
||||
- Keywords are limited to first 10 if more are provided
|
||||
|
||||
### Data Normalization
|
||||
- All string fields are trimmed of whitespace
|
||||
- Language and format values are normalized (first letter capitalized, rest lowercase)
|
||||
- Empty strings are converted to NULL in the database
|
||||
|
||||
### Entity Creation
|
||||
- Authors, supervisors, and keywords are automatically created if they don't exist
|
||||
- Existing authors are matched by name
|
||||
- Contact email is only associated with the first author
|
||||
|
||||
## Example CSV Structure
|
||||
|
||||

```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Common Issues
|
||||
1. **Encoding problems**: Ensure file is saved as UTF-8
|
||||
2. **Missing columns**: All 21 columns must be present, even if empty
|
||||
3. **Line breaks in fields**: Ensure fields containing newlines are properly quoted
|
||||
4. **Quote escaping**: Use double quotes (`""`) to escape quotes within fields
|
||||
|
||||
### Import Results
|
||||
After import, the system will display:
|
||||
- Number of theses successfully imported
|
||||
- Number of rows skipped due to errors
|
||||
- Detailed line-by-line results with success (✓) or error (✗) indicators
|
||||
|
||||
## Notes
|
||||
|
||||
- The import process preserves the order of authors, supervisors, and keywords
|
||||
- The first author gets the contact email if provided
|
||||
- Duplicate detection is not performed - each import creates new entries
|
||||
- Failed rows do not stop the import process
|
||||
- All errors are logged to the server error log

# Migration from YAML to SQLite
|
||||
|
||||
## Overview
|
||||
|
||||
The Post-ERG thesis submission form has been completely overhauled to use a SQLite database instead of flat YAML files. This provides better data integrity, querying capabilities, and prepares the system for a full-featured web application.
|
||||
|
||||
## What Changed
|
||||
|
||||
### Database Implementation
|
||||
|
||||
**Before:** Form data was saved as individual YAML files in `data/yaml/`, with file uploads scattered in `data/content/` and `data/cover/`.
|
||||
|
||||
**After:** All thesis data is now stored in a relational SQLite database (`../db/posterg.db`) with proper normalization and foreign key relationships.
|
||||
|
||||
### New Architecture
|
||||
|
||||
```
|
||||
Form Submission Flow:
|
||||
1. User fills out enhanced form (index.php)
|
||||
2. Form validates input and begins database transaction
|
||||
3. Creates/links: author, thesis, supervisors, keywords, languages, formats
|
||||
4. Uploads files with random names for security
|
||||
5. Records file metadata in database
|
||||
6. Commits transaction (all-or-nothing)
|
||||
7. Redirects to confirmation page showing database data
|
||||
```
|
||||
|
||||
### Database Schema Highlights
|
||||
|
||||
- **19 tables** including junction tables and views
|
||||
- **Normalized structure** (3rd Normal Form)
|
||||
- **Automatic timestamps** via triggers
|
||||
- **Cascade deletes** for referential integrity
|
||||
- **Predefined lookup tables** for orientations, AP programs, finalities, etc.
|
||||
- **Views** for simplified querying (v_theses_full, v_theses_public)
|
||||
|
||||
## New Files
|
||||
|
||||
### `Database.php`
|
||||
Database helper class providing:
|
||||
- PDO connection with error handling
|
||||
- Transaction management
|
||||
- Find-or-create methods for entities
|
||||
- Prepared statement helpers
|
||||
- Lookup methods for all reference data
|
||||
|
||||
**Key Methods:**
|
||||
```php
|
||||
$db = new Database();
|
||||
$authorId = $db->findOrCreateAuthor($name, $email);
|
||||
$keywordId = $db->findOrCreateKeyword($keyword);
|
||||
$orientations = $db->getAllOrientations();
|
||||
$thesis = $db->getThesis($id);
|
||||
```
|
||||
|
||||
## Modified Files
|
||||
|
||||
### `index.php`
|
||||
**Enhancements:**
|
||||
- Dynamically loads form options from database
|
||||
- Added required fields per schema:
|
||||
- Subtitle (optional)
|
||||
- Synopsis (~200 words, required)
|
||||
- Finality (Approfondi/Enseignement/Spécialisé)
|
||||
- Languages (multiple selection with checkboxes)
|
||||
- Formats (multiple selection with checkboxes)
|
||||
- Better form organization with sections
|
||||
- Improved accessibility (proper labels, IDs)
|
||||
|
||||
**New Form Fields:**
|
||||
| Field | Type | Required | Notes |
|
||||
|-------|------|----------|-------|
|
||||
| Subtitle | Text | No | New field |
|
||||
| Synopsis | Textarea | Yes | ~200 words |
|
||||
| Finality | Select | Yes | From finality_types table |
|
||||
| Languages | Checkboxes | Yes | Multiple selection |
|
||||
| Formats | Checkboxes | No | Multiple selection |
|
||||
|
||||
### `formulaire.php`
|
||||
**Complete rewrite** with:
|
||||
|
||||
1. **Transaction-Based Processing:**
|
||||
- `BEGIN TRANSACTION` at start
|
||||
- All insertions in single transaction
|
||||
- `COMMIT` on success or `ROLLBACK` on error
|
||||
- Ensures data consistency
|
||||
|
||||
2. **Prepared Statements:**
|
||||
- All SQL queries use PDO prepared statements
|
||||
- Protection against SQL injection
|
||||
- Parameter binding for all user input
|
||||
|
||||
3. **Entity Creation:**
|
||||
- Finds or creates authors (by name)
|
||||
- Finds or creates supervisors (by name)
|
||||
- Finds or creates keywords (by text)
|
||||
- Links all entities via junction tables
|
||||
|
||||
4. **Identifier Generation:**
|
||||
- Format: `YYYY-NNN` (e.g., "2026-001")
|
||||
- Automatically increments per year
|
||||
- Unique constraint in database
|
||||
|
||||
5. **File Handling:**
|
||||
- Random cryptographic filenames (32 hex chars)
|
||||
- Organized by year and identifier: `data/theses/YYYY/YYYY-NNN/`
|
||||
- Cover images separate: `data/covers/`
|
||||
- Metadata stored in `thesis_files` table
|
||||
|
||||
6. **Validation:**
|
||||
- Year range: 2000 to current year + 1
|
||||
- Max 10 keywords enforced
|
||||
- At least one language required
|
||||
- URL format validation
|
||||
- File type and size validation
|
||||
|
||||
### `thanks.php`
|
||||
**Complete redesign:**
|
||||
|
||||
- Reads from database using thesis ID
|
||||
- Displays data from `v_theses_full` view
|
||||
- Shows all relationships: authors, supervisors, keywords, languages, formats
|
||||
- Lists uploaded files with metadata (type, size, date)
|
||||
- Responsive CSS grid layout
|
||||
- Publication status indicator
|
||||
|
||||
**Security:**
|
||||
- Validates thesis ID (integer only)
|
||||
- Uses prepared statements
|
||||
- No path traversal vulnerability
|
||||
- Error messages don't expose system details
|
||||
|
||||
## Database Files

## Data Mapping
|
||||
|
||||
### YAML to Database Mapping
|
||||
|
||||
| Old YAML Field | New Database Location | Notes |
|
||||
|----------------|----------------------|-------|
|
||||
| `auteurice` | `authors.name` | Normalized, reusable |
|
||||
| `email` | `authors.email` | Now in authors table |
|
||||
| `année` | `theses.year` | Integer field |
|
||||
| `titre` | `theses.title` | Required |
|
||||
| - | `theses.subtitle` | New field |
|
||||
| `description` | `theses.synopsis` | Renamed for clarity |
|
||||
| `problématique` | (not yet used) | Can be added to schema |
|
||||
| `orientation` | `theses.orientation_id` | Foreign key to orientations |
|
||||
| `ap` | `theses.ap_program_id` | Foreign key to ap_programs |
|
||||
| - | `theses.finality_id` | New field (required) |
|
||||
| `promoteurice` | `supervisors.name` + `thesis_supervisors` | Many-to-many |
|
||||
| `tag` | `keywords.keyword` + `thesis_keywords` | Many-to-many, max 10 |
|
||||
| `lien` | `theses.baiu_link` | URL validation |
|
||||
| `files` | `thesis_files` table | Full metadata |
|
||||
| `couverture` | (stored as file, not in DB yet) | Could add cover_path column |
|
||||
|
||||
## Migration Path for Existing Data
|
||||
|
||||
If you have existing YAML files to import:
|
||||
|
||||
1. **Parse YAML files:**
|
||||
```php
|
||||
$yamlFiles = glob('data/yaml/*.yaml');
|
||||
foreach ($yamlFiles as $file) {
|
||||
$data = Yaml::parseFile($file);
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
2. **Insert into database:**
|
||||
```php
|
||||
$db->beginTransaction();
|
||||
try {
|
||||
$authorId = $db->findOrCreateAuthor($data['auteurice'], $data['email']);
|
||||
// Insert thesis
|
||||
// Link relationships
|
||||
$db->commit();
|
||||
} catch (Exception $e) {
|
||||
$db->rollback();
|
||||
}
|
||||
```
|
||||
|
||||
3. **Verify data:**
|
||||
```sql
|
||||
SELECT COUNT(*) FROM theses;
|
||||
SELECT * FROM v_theses_full LIMIT 5;
|
||||
```
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
Before production deployment:
|
||||
|
||||
- [ ] Form loads without errors
|
||||
- [ ] All dropdown options populate from database
|
||||
- [ ] Form submission creates thesis record
|
||||
- [ ] Author is created or found correctly
|
||||
- [ ] Supervisors linked properly
|
||||
- [ ] Keywords created and linked (test max 10)
|
||||
- [ ] Languages required (test validation)
|
||||
- [ ] Formats optional (test multiple selection)
|
||||
- [ ] Files upload successfully
|
||||
- [ ] File metadata recorded in database
|
||||
- [ ] Thanks page displays all data correctly
|
||||
- [ ] Transaction rollback works on error
|
||||
- [ ] CSRF token validated
|
||||
- [ ] Invalid data rejected (year, URL, etc.)
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No cover_path column:** Cover images uploaded but path not stored in `theses` table (can be added)
|
||||
2. **No problématique field:** Old field not yet in schema (can be added to `theses.remarks` or new column)
|
||||
3. **File type detection:** Basic (by extension), could be enhanced
|
||||
4. **No duplicate detection:** Same thesis can be submitted multiple times
|
||||
5. **No edit capability:** Once submitted, no UI to edit (admin interface needed)
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. **Initialize production database:**
|
||||
```bash
|
||||
cd /path/to/production/db
|
||||
sqlite3 posterg.db < schema.sql
|
||||
```
|
||||
|
||||
2. **Set permissions:**
|
||||
```bash
|
||||
chmod 644 posterg.db
|
||||
chown www-data:www-data posterg.db
|
||||
```
|
||||
|
||||
3. **Test form submission:**
|
||||
- Submit test thesis
|
||||
- Verify all fields saved
|
||||
- Check file uploads
|
||||
- Test thanks page
|
||||
|
||||
4. **Import existing data:**
|
||||
- Create migration script
|
||||
- Parse old YAML files
|
||||
- Bulk insert into database
|
||||
- Verify integrity
|
||||
|
||||
5. **Build admin interface:**
|
||||
- CRUD operations for theses
|
||||
- User management
|
||||
- Approval workflow
|
||||
- Bulk operations
|
||||
|
||||
6. **Build public website:**
|
||||
- Search and filter theses
|
||||
- Respect access controls
|
||||
- Display thesis details
|
||||
- Static pages management
|
||||
|
||||
## Compatibility Notes
|
||||
|
||||
### PHP Requirements
|
||||
- PHP 7.4+ (tested on PHP 8.x)
|
||||
- PDO extension with SQLite support
|
||||
- Composer for Symfony YAML (still used for potential migration)
|
||||
|
||||
### Database
|
||||
- SQLite 3.8.0+
|
||||
- File-based database (no server needed)
|
||||
- Single file: `db/posterg.db`
|
||||
|
||||
### Dependencies
|
||||
```json
|
||||
{
|
||||
"require": {
|
||||
"symfony/yaml": "^6.2",
|
||||
"behat/transliterator": "^1.5"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Note: YAML library retained for potential data migration from old files.
|
||||
|
||||
## Backup Strategy
|
||||
|
||||
SQLite database is a single file - easy to backup:
|
||||
|
||||
```bash
|
||||
# Simple copy
|
||||
cp db/posterg.db db/backups/posterg_$(date +%Y%m%d).db
|
||||
|
||||
# SQL dump (portable)
|
||||
sqlite3 db/posterg.db .dump > backups/posterg_$(date +%Y%m%d).sql
|
||||
|
||||
# Compressed backup
|
||||
tar -czf backups/posterg_$(date +%Y%m%d).tar.gz db/posterg.db data/
|
||||
```
|
||||
|
||||
Set up automated daily backups via cron.
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
- **Indexes:** All critical foreign keys and search fields indexed
|
||||
- **Views:** Pre-computed joins for common queries
|
||||
- **Transactions:** Ensure atomicity without locking issues
|
||||
- **File I/O:** Random filenames prevent directory listing overhead
|
||||
|
||||
For large datasets (1000+ theses):
|
||||
- Consider WAL mode: `PRAGMA journal_mode=WAL;`
|
||||
- Optimize with `ANALYZE;` periodically
|
||||
- Monitor database size and `VACUUM` if needed
|
||||
|
||||
## Rollback Plan
|
||||
|
||||
If issues arise, you can roll back to YAML-based system:
|
||||
|
||||
1. Use previous jj commit: `jj checkout <commit-id>`
|
||||
2. Old YAML files in `data/yaml/` still intact
|
||||
3. Database changes don't affect old YAML code
|
||||
4. Can run both systems in parallel during transition
|
||||

## Example Searches
|
||||
|
||||
### Basic Search
|
||||
```
|
||||
search.php?query=urbain
|
||||
→ Finds "Espaces Urbains et Narration Collective"
|
||||
```
|
||||
|
||||
### Year Filter
|
||||
```
|
||||
search.php?year=2024

```
|
||||
|
||||
---
|
||||
|
||||
## Security Highlights
|
||||
|
||||
### Input Validation
|
||||
|
||||
**Before (Vulnerable)**:
|
||||
```php
|
||||
$bindings[':query'] = '%' . $params['query'] . '%';
|
||||
// User input "%" → matches EVERYTHING
|
||||
```
|
||||
|
||||
**After (Secure)**:
|
||||
```php
|
||||
$validated = $this->escapeLikeString($params['query']);
|
||||
$bindings[':query'] = '%' . $validated . '%';
|
||||
// User input "%" → escapes to "\%" → matches literal %
|
||||
// SQL: LIKE :query ESCAPE '\'
|
||||
```
|
||||
|
||||
### Rate Limiting Flow
|
||||
|
||||
```
|
||||
Request → RateLimit::check()
|
||||
↓
|
||||
Allowed? ───No──→ HTTP 429 + Error page
|
||||
↓
|
||||
Yes
|
||||
↓
|
||||
Process search → Return results
|
||||
↓
|
||||
Send X-RateLimit-* headers
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Production Deployment
|
||||
|
||||
### Pre-deployment Checklist
|
||||
|
||||
- [x] All tests passing
|
||||
- [x] Security validated
|
||||
- [x] Rate limiting configured
|
||||
- [x] Cache directory created (755)
|
||||
- [x] Error handling in place
|
||||
- [x] Documentation complete
|
||||
|
||||
### Server Requirements
|
||||
|
||||
- [ ] PHP 7.4+ with PDO SQLite
|
||||
- [ ] Write permissions on cache/ directory
|
||||
- [ ] HTTPS enabled (recommended)
|
||||
- [ ] Error logging configured
|
||||
|
||||
### Post-deployment
|
||||
|
||||
1. Monitor `error.log` for issues
|
||||
2. Check rate limit cache growth
|
||||
3. Analyze search patterns
|
||||
4. Adjust rate limits if needed
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Rate Limiting Not Working
|
||||
|
||||
**Check**:
|
||||
```bash
|
||||
# Cache directory exists and is writable
|
||||
ls -la cache/rate_limit
|
||||
# Should show: drwxr-xr-x
|
||||
```
|
||||
|
||||
**Fix**:
|
||||
```bash
|
||||
mkdir -p cache/rate_limit
|
||||
chmod 755 cache/rate_limit
|
||||
```
|
||||
|
||||
### Search Returns No Results
|
||||
|
||||
**Check**:
|
||||
1. Database exists: `ls ../formulaire/test.db`
|
||||
2. Database has data: `php test_search.php`
|
||||
3. Theses are published: `is_published = 1`
|
||||
|
||||
### Validation Errors
|
||||
|
||||
If users see "Search query too long":
|
||||
- Current limit: 200 characters
|
||||
- Adjust in `Database.php` → `validateSearchParams()`
|
||||
|
||||

|
||||
|
||||
## Performance Notes
|
||||
|
||||
### Optimized For
|
||||
- SQLite full-text search across multiple fields
|
||||
- Efficient LIKE queries with proper escaping
|
||||
- Indexed columns (year, published, orientation, AP)
|
||||
- Limited result sets (max 100/page)
|
||||
|
||||

## Testing the Search Feature
|
||||
|
||||
### 1. Create Test Database
|
||||
Run the script to generate sample data:
|
||||
```bash
|
||||
cd /home/padlock/dev/posterg-website/front-backend
|
||||
php create_test_db.php
|
||||
```
|
||||
|
||||
This will create `test.db` in the `formulaire/` directory with:
|
||||
- 6 sample theses (various years, orientations, and programs)
|
||||
- 5 sample authors
|
||||
- 3 sample supervisors
|
||||
- 20 keywords
|
||||
- Complete relationships (authors, supervisors, keywords, formats, languages)
|
||||
|
||||
### 2. Access the Search Page
|
||||
Navigate to: `search.php`
|
||||
|
||||
### 3. Test Search Scenarios
|
||||
|
||||
#### Scenario 1: Full-text Search
|
||||
- Enter "urbain" in the search field
|
||||
- Should find: "Espaces Urbains et Narration Collective"
|
||||
|
||||
#### Scenario 2: Filter by Year
|
||||
- Select year: 2024
|
||||
- Should find: 3 theses from 2024
|
||||
|
||||
#### Scenario 3: Filter by Orientation
|
||||
- Select orientation: "Installation-Performance"
|
||||
- Should find: 2 theses
|
||||
|
||||
#### Scenario 4: Filter by AP Program
|
||||
- Select AP: "Narration Spéculative"
|
||||
- Should find: 2 theses
|
||||
|
||||
#### Scenario 5: Combined Filters
|
||||
- Enter "performance" in search field
|
||||
- Select year: 2024
|
||||
- Should find: 1 thesis ("Corps et Technologies")
|
||||
|
||||
#### Scenario 6: Keyword Search
|
||||
- Select keyword: "écologie"
|
||||
- Should find: "Écologies Affectives"
|
||||
|
||||
## Database Schema Reference
|
||||
|
||||
The search uses the `v_theses_public` view which combines:
|
||||
- Main thesis data from `theses` table
|
||||
- Related authors via `thesis_authors` junction table
|
||||
- Related supervisors via `thesis_supervisors` junction table
|
||||
- Related keywords via `thesis_keywords` junction table
|
||||
- Related formats via `thesis_formats` junction table
|
||||
- Related languages via `thesis_languages` junction table
|
||||
- Predefined values from lookup tables (orientations, ap_programs, finality_types, etc.)
|
||||
|
||||
## Features
|
||||
|
||||
### Pagination
|
||||
- Results are paginated (20 items per page)
|
||||
- Previous/Next navigation
|
||||
- Numbered page links
|
||||
|
||||
### Result Display
|
||||
- Shows total number of results
|
||||
- Card-based layout matching the main index page
|
||||
- Displays: title, author, year, synopsis excerpt
|
||||
- Links to full thesis detail page
|
||||
|
||||
### User Experience
|
||||
- All filters are optional
|
||||
- Filters can be combined
|
||||
- "Réinitialiser" button to clear all filters
|
||||
- Maintains filter state during pagination
|
||||
|
||||
## Security Considerations
|
||||
|
||||
- All user inputs are sanitized using `htmlspecialchars()`
|
||||
- SQL queries use prepared statements with parameter binding
|
||||
- No direct SQL injection risk
|
||||
- Only published theses are searchable (`is_published = 1`)
|
||||
|
||||
## Future Enhancements
|
||||
|
||||
Potential improvements:
|
||||
1. **Auto-complete** - Suggest keywords/authors as user types
|
||||
2. **Faceted search** - Show filter counts (e.g., "Peinture (12)")
|
||||
3. **Sort options** - Sort by year, title, relevance
|
||||
4. **Save searches** - Allow users to bookmark search queries
|
||||
5. **Export results** - Export search results as CSV/JSON
|
||||
6. **Advanced boolean search** - Support AND/OR/NOT operators
|
||||
7. **Search highlights** - Highlight matching terms in results
|
||||
8. **Related theses** - Show similar works based on keywords
|
||||
9. **Statistics** - Show search analytics and popular queries
|
||||
10. **AJAX search** - Live search without page reload
|
||||
|
||||
## Technical Notes
|
||||
|
||||
- Uses SQLite LIKE operator for text matching (case-insensitive)
|
||||
- Searches across GROUP_CONCAT fields in the view for many-to-many relationships
|
||||
- Efficient use of indexes defined in schema.sql
|
||||
- Compatible with existing Database.php singleton pattern

# Security Improvements
|
||||
|
||||
## Changes Made
|
||||
|
||||
### 1. Critical Vulnerability Fixes
|
||||
|
||||
#### Path Traversal in thanks.php (CRITICAL)
|
||||
- **Before**: User could access ANY file on the system via `?file=../../../../etc/passwd`
|
||||
- **After**:
|
||||
- Validates file path using `realpath()` to resolve symlinks
|
||||
- Ensures file is within allowed `data/yaml/` directory
|
||||
- Verifies file extension is `.yaml`
|
||||
- Proper error handling without exposing system paths
|
||||
|
||||
#### CSRF Protection
|
||||
- **Before**: Form could be submitted from any website
|
||||
- **After**:
|
||||
- Session-based CSRF tokens generated for each form load
|
||||
- Token validated on submission using timing-safe comparison (`hash_equals()`)
|
||||
- Token cleared after successful submission
|
||||
|
||||
### 2. Input Validation & Sanitization
|
||||
|
||||
#### Deprecated Functions Replaced
|
||||
- **Before**: Used `FILTER_SANITIZE_STRING` (deprecated in PHP 8.1+)
|
||||
- **After**: Custom `sanitize_string()` function using `htmlspecialchars()` and `strip_tags()`
|
||||
|
||||
#### Enhanced Validation
|
||||
- Required fields properly validated with custom `validate_required()` function
|
||||
- Email validation using `FILTER_VALIDATE_EMAIL`
|
||||
- URL validation using `FILTER_VALIDATE_URL`
|
||||
- Year validation with reasonable range checking (2000 to current year + 1)
|
||||
- Comprehensive error messages for validation failures
|
||||
|
||||
### 3. File Upload Security
|
||||
|
||||
#### Random Filenames
|
||||
- **Before**: Used original or predictable filenames (author + timestamp)
|
||||
- **After**:
|
||||
- Generates cryptographically secure random filenames using `random_bytes()`
|
||||
- Prevents file overwrites
|
||||
- Prevents path traversal attacks via malicious filenames
|
||||
- Stores mapping to original filename for reference
|
||||
|
||||
#### Enhanced File Validation
|
||||
- MIME type checking using `finfo`
|
||||
- File extension whitelist
|
||||
- File size limits (50MB max)
|
||||
- Proper error handling for upload errors
|
||||
- Cover image restricted to JPEG/PNG only
|
||||
|
||||
### 4. Bug Fixes
|
||||
|
||||
- Fixed undefined variable `$memoireFolder` (used before definition)
|
||||
- Fixed undefined variable `$resume` (should be `$description`)
|
||||
- Fixed variable ordering (generate `$uniqueId` before using it)
|
||||
- Added proper `__DIR__` prefix for absolute paths
|
||||
|
||||
### 5. Error Handling
|
||||
|
||||
- Try-catch block wraps entire form processing
|
||||
- Detailed error logging (not exposed to users)
|
||||
- User-friendly error messages
|
||||
- Proper exit after redirect
|
||||
- No system path exposure in error messages
|
||||
|
||||
## Nginx Configuration Notes
|
||||
|
||||
Since this form is behind nginx password authentication, additional security layers:
|
||||
|
||||
### Recommended nginx config:
|
||||
```nginx
|
||||
location /formulaire {
|
||||
auth_basic "Restricted Access";
|
||||
auth_basic_user_file /etc/nginx/.htpasswd;
|
||||
|
||||
# Rate limiting
|
||||
limit_req zone=form_limit burst=5 nodelay;
|
||||
|
||||
# File upload size
|
||||
client_max_body_size 100M;
|
||||
|
||||
# Timeout settings
|
||||
client_body_timeout 60s;
|
||||
|
||||
# Prevent access to sensitive files
|
||||
location ~ /\. {
|
||||
deny all;
|
||||
}
|
||||
|
||||
location ~ /(vendor|composer\.(json|lock)|error\.log)$ {
|
||||
deny all;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Additional Recommendations
|
||||
|
||||
### 1. Database Migration (In Progress)
|
||||
Moving to SQLite will provide:
|
||||
- Structured data storage
|
||||
- Better query capabilities
|
||||
- Easier data management
|
||||
- Prepared statements for SQL injection prevention
|
||||
|
||||
### 2. File Storage
|
||||
- Consider moving uploaded files outside web root
|
||||
- Serve files through PHP script with access control
|
||||
- Implement file scanning for malware if possible
|
||||
|
||||
### 3. Monitoring
|
||||
- Regularly review `error.log` for suspicious activity
|
||||
- Monitor file upload patterns
|
||||
- Set up alerts for failed CSRF validations
|
||||
|
||||
### 4. Backup Strategy
|
||||
- Regular backups of `data/` directory
|
||||
- Version control for code changes
|
||||
- Test restore procedures
|
||||
|
||||
### 5. PHP Configuration
|
||||
Ensure these settings in php.ini:
|
||||
```ini
|
||||
file_uploads = On
|
||||
upload_max_filesize = 100M
|
||||
post_max_size = 100M
|
||||
max_execution_time = 60
|
||||
max_input_time = 60
|
||||
memory_limit = 256M
|
||||
|
||||
# Security
|
||||
expose_php = Off
|
||||
allow_url_fopen = Off
|
||||
allow_url_include = Off
|
||||
display_errors = Off
|
||||
log_errors = On
|
||||
```
|
||||
|
||||
## Testing Checklist
|
||||
|
||||
- [ ] Form submission with all fields
|
||||
- [ ] Form submission with minimal required fields
|
||||
- [ ] Invalid email format
|
||||
- [ ] Invalid URL format
|
||||
- [ ] Invalid year
|
||||
- [ ] File upload (various formats)
|
||||
- [ ] Large file upload (>50MB, should fail)
|
||||
- [ ] Invalid file types
|
||||
- [ ] Multiple file uploads
|
||||
- [ ] Cover image upload
|
||||
- [ ] CSRF token validation (try submitting with wrong token)
|
||||
- [ ] Path traversal attempt in thanks.php
|
||||
- [ ] Error handling for missing directories
|
||||
|
||||
## Known Limitations
|
||||
|
||||
1. **No atomic transactions**: File operations and YAML save not atomic
|
||||
2. **No rollback**: Failed submissions may leave partial files
|
||||
3. **Session storage**: CSRF tokens in default PHP session (consider database sessions)
|
||||
4. **No upload progress**: Large files have no progress indicator
|
||||
5. **No duplicate detection**: Same submission can be made multiple times
|
||||
|
||||
These limitations will be addressed in the SQLite migration.

# Security Analysis - Search Feature
|
||||
|
||||
## Current Security Status
|
||||
|
||||
### ✅ Protections in Place
|
||||
|
||||
1. **SQL Injection Prevention**
|
||||
- ✅ Uses PDO prepared statements
|
||||
- ✅ All parameters bound with `bindValue()`
|
||||
- ✅ No direct concatenation of user input into SQL
|
||||
- ✅ Dynamic WHERE clause built from hardcoded strings only
|
||||
|
||||
2. **XSS (Cross-Site Scripting) Prevention**
|
||||
- ✅ All output uses `htmlspecialchars()`
|
||||
- ✅ Form values escaped when displayed
|
||||
- ✅ Search results escaped before rendering
|
||||
|
||||
3. **Access Control**
|
||||
- ✅ Only published theses searchable (`is_published = 1`)
|
||||
- ✅ Uses read-only view (`v_theses_public`)
|
||||
|
||||
4. **Type Safety**
|
||||
- ✅ Year parameter uses `intval()`
|
||||
- ✅ Boolean values properly cast
|
||||
|

|
||||
|
||||
## ⚠️ Security Vulnerabilities
|
||||
|
||||
### 1. LIKE Wildcard Injection (Low Severity)
|
||||
|
||||
**Issue:** Users can inject SQL LIKE wildcards (`%`, `_`) to match unintended patterns.
|
||||
|
||||
**Example Attack:**
|
||||
```
|
||||
Search query: "%"
|
||||
Result: Matches ALL theses (bypasses search intent)
|
||||
|
||||
Search query: "a%b%c%d%e%f%g%h%i%j%k%l%m%n%o%p%q%r%s%t%u%v%w%x%y%z"
|
||||
Result: Forces inefficient pattern matching, potential DoS
|
||||
```
|
||||
|
||||
**Current Code:**
|
||||
```php
|
||||
$bindings[':query'] = '%' . $params['query'] . '%';
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Not SQL injection (still uses prepared statements)
|
||||
- Allows overly broad searches
|
||||
- Performance degradation with complex patterns
|
||||
- Information disclosure through pattern matching
|
||||
|
||||
**Fix:** Escape wildcards before using in LIKE:
|
||||
```php
|
||||
private function escapeLikeString($string) {
|
||||
return str_replace(['\\', '%', '_'], ['\\\\', '\\%', '\\_'], $string);
|
||||
}
|
||||
|
||||
// In query:
|
||||
$bindings[':query'] = '%' . $this->escapeLikeString($params['query']) . '%';
|
||||
|
||||
// In SQL:
|
||||
"title LIKE :query ESCAPE '\\'"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. No Input Length Validation (Medium Severity)
|
||||
|
||||
**Issue:** No limits on search string length.
|
||||
|
||||
**Example Attack:**
|
||||
```php
|
||||
// 10MB query string
|
||||
$query = str_repeat('a', 10 * 1024 * 1024);
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Memory exhaustion
|
||||
- Database query slowdown
|
||||
- Denial of Service (DoS)
|
||||
|
||||
**Fix:** Validate input length:
|
||||
```php
|
||||
if (strlen($params['query']) > 200) {
|
||||
throw new InvalidArgumentException("Search query too long");
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. No Rate Limiting (Medium Severity)
|
||||
|
||||
**Issue:** Unlimited search requests allowed.
|
||||
|
||||
**Example Attack:**
|
||||
```bash
|
||||
# Spam 10,000 requests
|
||||
for i in {1..10000}; do
|
||||
curl "http://site.com/search.php?query=test&page=$i" &
|
||||
done
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Database overload
|
||||
- Server resource exhaustion
|
||||
- Denial of Service for legitimate users
|
||||
|
||||
**Fix:** Implement rate limiting (see solution below)
|
||||
|
||||
---
|
||||
|
||||
### 4. No Pagination Limits (Low Severity)
|
||||
|
||||
**Issue:** Users can request excessive offset values.
|
||||
|
||||
**Example:**
|
||||
```
|
||||
search.php?page=999999999
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Database scans large result sets
|
||||
- Wasted resources on impossible pages
|
||||
|
||||
**Fix:** Validate pagination:
|
||||
```php
|
||||
$limit = max(1, min(100, intval($limit))); // Max 100 per page
|
||||
$offset = max(0, intval($offset));
|
||||
|
||||
// Optionally limit max offset
|
||||
if ($offset > 10000) {
|
||||
throw new InvalidArgumentException("Page too high");
|
||||
}
|
||||
```
|

## 🔒 Recommended Security Improvements
|
||||
|
||||
### Priority 1: Apply Input Validation (HIGH)
|
||||
|
||||
Use the enhanced `Database_secure.php` class which includes:
|
||||
- Wildcard escaping
|
||||
- Length validation
|
||||
- Range validation
|
||||
- ESCAPE clause in LIKE queries
|
||||
|
||||
### Priority 2: Implement Rate Limiting (MEDIUM)
|
||||
|
||||
Example using simple file-based rate limiting:
|
||||
|
||||
```php
|
||||
<?php
|
||||
// rate_limit.php - Simple rate limiter
|
||||
|
||||
function checkRateLimit($identifier, $maxRequests = 10, $timeWindow = 60) {
|
||||
$cacheDir = __DIR__ . '/cache/rate_limit';
|
||||
if (!is_dir($cacheDir)) {
|
||||
mkdir($cacheDir, 0755, true);
|
||||
}
|
||||
|
||||
$file = $cacheDir . '/' . md5($identifier) . '.json';
|
||||
|
||||
$data = file_exists($file) ? json_decode(file_get_contents($file), true) : [];
|
||||
|
||||
// Clean old entries
|
||||
$now = time();
|
||||
$data = array_filter($data, function($timestamp) use ($now, $timeWindow) {
|
||||
return ($now - $timestamp) < $timeWindow;
|
||||
});
|
||||
|
||||
// Check if limit exceeded
|
||||
if (count($data) >= $maxRequests) {
|
||||
return false;
|
||||
}
|
||||
|
||||
// Add new request
|
||||
$data[] = $now;
|
||||
file_put_contents($file, json_encode($data));
|
||||
|
||||
return true;
|
||||
}
|
||||
|
||||
// In search.php:
|
||||
$userIP = $_SERVER['REMOTE_ADDR'];
|
||||
if (!checkRateLimit($userIP, 20, 60)) { // 20 requests per minute
|
||||
http_response_code(429);
|
||||
die('Too many requests. Please try again later.');
|
||||
}
|
||||
```
|
||||
|
||||
### Priority 3: Add Content Security Policy (LOW)
|
||||
|
||||
Add to header:
|
||||
```php
|
||||
header("Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline' cdn.jsdelivr.net;");
|
||||
header("X-Content-Type-Options: nosniff");
|
||||
header("X-Frame-Options: DENY");
|
||||
header("X-XSS-Protection: 1; mode=block");
|
||||
```
|
||||
|
||||
### Priority 4: Add Query Logging (LOW)
|
||||
|
||||
Log suspicious search patterns:
|
||||
```php
|
||||
// Detect potential attacks
|
||||
if (preg_match('/[%_]{10,}/', $params['query'])) {
|
||||
error_log("Suspicious search pattern from {$_SERVER['REMOTE_ADDR']}: {$params['query']}");
|
||||
}
|
||||
```
|
||||
|
||||

|
||||
|
||||
## Security Best Practices Checklist
|
||||
|
||||
- [x] Use prepared statements (SQL injection)
|
||||
- [x] Escape output with htmlspecialchars() (XSS)
|
||||
- [ ] Escape LIKE wildcards (wildcard injection)
|
||||
- [ ] Validate input lengths (DoS)
|
||||
- [ ] Implement rate limiting (DoS)
|
||||
- [ ] Validate pagination limits (resource waste)
|
||||
- [x] Restrict to published data only (access control)
|
||||
- [ ] Add security headers (defense in depth)
|
||||
- [ ] Log suspicious activity (monitoring)
|
||||
- [ ] Use HTTPS in production (encryption)
|
||||
|
||||
---
|
||||
|
||||
## Testing Security
|
||||
|
||||
### Test 1: SQL Injection
|
||||
```bash
|
||||
# These should NOT cause errors or expose data
|
||||
curl "search.php?query=' OR 1=1--"
|
||||
curl "search.php?query='; DROP TABLE theses;--"
|
||||
curl "search.php?year=' OR '1'='1"
|
||||
```
|
||||
**Expected:** Treated as literal search strings, no SQL execution
|
||||
|
||||
### Test 2: XSS
|
||||
```bash
|
||||
curl "search.php?query=<script>alert('XSS')</script>"
|
||||
```
|
||||
**Expected:** Script tags displayed as text, not executed
|
||||
|
||||
### Test 3: Wildcard Injection
|
||||
```bash
|
||||
curl "search.php?query=%"
|
||||
```
|
||||
**Current:** Returns all results ❌
|
||||
**After fix:** Searches for literal "%" character ✅
|
||||
|
||||
### Test 4: DoS via Long Input
|
||||
```bash
|
||||
curl "search.php?query=$(python3 -c 'print("a"*100000)')"
|
||||
```
|
||||
**Current:** Processes full string ❌
|
||||
**After fix:** Rejects with error ✅
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
**Current Status:** The search system has **good baseline security** against SQL injection and XSS, but needs hardening for production use.
|
||||
|
||||
**Recommended Actions:**
|
||||
1. Apply wildcard escaping (use `Database_secure.php`)
|
||||
2. Add input length validation
|
||||
3. Implement rate limiting
|
||||
4. Add security headers
|
||||
5. Monitor for suspicious patterns
|
||||
|
||||
**Risk Level:**
|
||||
- Current: **Medium** (suitable for internal/development use)
|
||||
- After improvements: **Low** (production-ready)

# Security Implementation - Production Ready
|
||||
|
||||
## Overview
|
||||
|
||||
The search system has been hardened with comprehensive security measures and is now **production-ready**.
|
||||
|
||||
## Security Features Implemented
|
||||
|
||||
### ✅ 1. SQL Injection Protection
|
||||
- **Method**: PDO prepared statements with parameter binding
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: All injection attempts treated as literal strings
|
||||
- **Coverage**: All database queries
|
||||
|
||||
### ✅ 2. XSS (Cross-Site Scripting) Protection
|
||||
- **Method**: `htmlspecialchars()` on all output
|
||||
- **Status**: ✅ SECURE
|
||||
- **Coverage**: All user-generated content display
|
||||
|
||||
### ✅ 3. Wildcard Injection Prevention
|
||||
- **Method**: Escape LIKE wildcards (`%`, `_`) before queries
|
||||
- **Implementation**: `escapeLikeString()` private method
|
||||
- **SQL**: Uses `ESCAPE '\\'` clause in all LIKE queries
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: Searching for `%` returns 0 results instead of all records
|
||||
|
||||
**Example:**
|
||||
```php
|
||||
// User input: "%"
|
||||
// Before: '%' . $query . '%' → "%%%" (matches everything)
|
||||
// After: '%' . escapeLikeString($query) . '%' → "%\%%" (matches literal %)
|
||||
```
|
||||
|
||||
### ✅ 4. Input Length Validation
|
||||
- **Limits**:
|
||||
- Query: 200 characters max
|
||||
- Orientation/AP/Finality: 100 characters max
|
||||
- Keywords/Formats: 100 characters max
|
||||
- Languages: 50 characters max
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: 4000-character input rejected with error message
|
||||
|
||||
### ✅ 5. Year Range Validation
|
||||
- **Allowed Range**: 1900-2100
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: Year 999999 rejected with "Invalid year" error
|
||||
|
||||
### ✅ 6. Pagination Limits
|
||||
- **Maximum per page**: 100 results
|
||||
- **Minimum per page**: 1 result
|
||||
- **Offset validation**: Non-negative values only
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: Request for 500 results limited to 100
|
||||
|
||||
### ✅ 7. Rate Limiting (NEW)
|
||||
- **Limit**: 30 requests per minute per IP address
|
||||
- **Method**: File-based tracking
|
||||
- **HTTP Status**: 429 Too Many Requests when exceeded
|
||||
- **Headers Sent**:
|
||||
- `X-RateLimit-Limit: 30`
|
||||
- `X-RateLimit-Remaining: N`
|
||||
- `X-RateLimit-Reset: timestamp`
|
||||
- `Retry-After: seconds`
|
||||
- **Status**: ✅ SECURE
|
||||
- **Test Result**: All tests pass, 6th request blocked correctly
|
||||
|
||||
**Features:**
|
||||
- Automatic cleanup of old rate limit files
|
||||
- Per-IP tracking (handles X-Forwarded-For for proxies)
|
||||
- Graceful error message in French
|
||||
- 1% chance of cleanup on each request (low overhead)

|
||||
|
||||
## Configuration
|
||||
|
||||
### Rate Limiting
|
||||
|
||||
Current settings in `search.php`:
|
||||
```php
|
||||
$rateLimit = new RateLimit(30, 60); // 30 requests per minute
|
||||
```
|
||||
|
||||
To adjust:
|
||||
```php
|
||||
// More restrictive (10 requests per minute)
|
||||
$rateLimit = new RateLimit(10, 60);
|
||||
|
||||
// More permissive (60 requests per minute)
|
||||
$rateLimit = new RateLimit(60, 60);
|
||||
|
||||
// Different time window (100 requests per hour)
|
||||
$rateLimit = new RateLimit(100, 3600);
|
||||
```
|
||||
|
||||
### Pagination
|
||||
|
||||
Current setting in Database.php:
|
||||
```php
|
||||
$limit = max(1, min(100, intval($limit))); // Max 100 per page
|
||||
```
|
||||
|
||||
Default in search.php:
|
||||
```php
|
||||
$itemsPerPage = min(100, isset($_GET['per_page']) ? intval($_GET['per_page']) : 20);
|
||||
```
|
||||
|
||||
Users can request different page sizes:
|
||||
- `search.php?per_page=50` - 50 results per page
|
||||
- `search.php?per_page=1000` - Capped at 100
|
||||
|
||||
---
|
||||
|
||||
## Security Headers
|
||||
|
||||
Consider adding these to production (in header.php or .htaccess):
|
||||
|
||||
```php
|
||||
// Content Security Policy
|
||||
header("Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline' cdn.jsdelivr.net; style-src 'self' 'unsafe-inline' cdn.jsdelivr.net;");
|
||||
|
||||
// Prevent MIME sniffing
|
||||
header("X-Content-Type-Options: nosniff");
|
||||
|
||||
// Prevent clickjacking
|
||||
header("X-Frame-Options: DENY");
|
||||
|
||||
// XSS Protection
|
||||
header("X-XSS-Protection: 1; mode=block");
|
||||
|
||||
// Referrer Policy
|
||||
header("Referrer-Policy: strict-origin-when-cross-origin");
|
||||
```
|
||||
|
||||

|
||||
|
||||
---
|
||||
|
||||
## Error Handling
|
||||
|
||||
### User-Facing Errors
|
||||
|
||||
1. **Rate Limit Exceeded** (429):
|
||||
```
|
||||
Trop de requêtes
|
||||
Vous avez dépassé la limite de 30 recherches par minute.
|
||||
Veuillez réessayer dans X secondes.
|
||||
```
|
||||
|
||||
2. **Validation Error** (400):
|
||||
```
|
||||
Erreur de validation : Search query too long (max 200 characters)
|
||||
```
|
||||
|
||||
3. **Database Error** (500):
|
||||
```
|
||||
Une erreur est survenue lors de la recherche.
|
||||
```
|
||||
|
||||
### Error Logging
|
||||
|
||||
All errors are logged to `error.log`:
|
||||
- Database connection failures
|
||||
- Search validation errors
|
||||
- Unexpected exceptions
|
||||
- Rate limit violations (can be enabled)
|
||||
|
||||
---
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Database Indexes
|
||||
|
||||
Ensure these indexes exist (from schema.sql):
|
||||
- `idx_theses_year` - Year filtering
|
||||
- `idx_theses_published` - Published filter
|
||||
- `idx_theses_orientation` - Orientation filtering
|
||||
- `idx_theses_ap_program` - AP program filtering
|
||||
- `idx_thesis_keywords_thesis` - Keyword searches
|
||||
|
||||
### Rate Limit Cache
|
||||
|
||||
- Location: `front-backend/cache/rate_limit/`
|
||||
- File per IP: `{md5_hash}.json`
|
||||
- Automatic cleanup: Old files removed after 24h
|
||||
- Permissions: Ensure directory is writable (755)
|
||||
|
||||
---
|
||||
|
||||
## Monitoring Recommendations
|
||||
|
||||
### Metrics to Track
|
||||
|
||||
1. **Search patterns**:
|
||||
- Most searched terms
|
||||
- Filter combinations used
|
||||
- Peak search times
|
||||
|
||||
2. **Rate limiting**:
|
||||
- Number of 429 errors
|
||||
- IPs hitting rate limits
|
||||
- Potential abuse patterns
|
||||
|
||||
3. **Performance**:
|
||||
- Search query duration
|
||||
- Database response time
|
||||
- Cache file growth
|
||||
|
||||
### Log Analysis
|
||||
|
||||
Monitor `error.log` for:
|
||||
- `Search validation error:` - Invalid inputs
|
||||
- `Error in search:` - Database issues
|
||||
- `Suspicious search pattern from` - Potential attacks (can be enabled)
|
||||
|
||||
---
|
||||
|
||||
## Maintenance
|
||||
|
||||
### Weekly Tasks
|
||||
- Review error logs
|
||||
- Check rate limit violations
|
||||
- Monitor disk usage of cache directory
|
||||
|
||||
### Monthly Tasks
|
||||
- Analyze search patterns
|
||||
- Review and update security measures
|
||||
- Test backup restoration
|
||||
|
||||
### As Needed
|
||||
- Adjust rate limits based on usage
|
||||
- Update input validation rules
|
||||
- Optimize slow queries
|
||||

# PHP Testing Best Practices
|
||||
|
||||
## Standard PHP Testing Structure
|
||||
|
||||
### Industry Standard: PHPUnit
|
||||
|
||||
The de facto standard for PHP testing is **PHPUnit**. Here's how professional PHP projects handle testing:
|
||||
|
||||
## Proper Directory Structure
|
||||
|
||||
```
|
||||
front-backend/
|
||||
├── src/ # Application code (or keep in root for small projects)
|
||||
│ ├── Database.php
|
||||
│ ├── RateLimit.php
|
||||
│ └── ...
|
||||
├── tests/ # All tests go here
|
||||
│ ├── Unit/ # Unit tests (test individual methods)
|
||||
│ │ ├── DatabaseTest.php
|
||||
│ │ └── RateLimitTest.php
|
||||
│ ├── Integration/ # Integration tests (test multiple components)
|
||||
│ │ └── SearchTest.php
|
||||
│ └── Security/ # Security-specific tests
|
||||
│ └── SecurityTest.php
|
||||
├── public/ # Public-facing files (or web root)
|
||||
│ ├── index.php
|
||||
│ ├── search.php
|
||||
│ └── assets/
|
||||
├── vendor/ # Dependencies (git-ignored, not deployed)
|
||||
├── cache/ # Runtime cache (not deployed)
|
||||
├── composer.json # Dependency management
|
||||
├── phpunit.xml # PHPUnit configuration
|
||||
└── .gitignore # Excludes tests, vendor, cache from git
|
||||
```
|
||||
|
||||
## What We Currently Have (Non-Standard)
|
||||
|
||||
```
|
||||
front-backend/
|
||||
├── test_search.php ❌ Tests in root
|
||||
├── test_security.php ❌ No framework
|
||||
├── test_rate_limit.php ❌ Would deploy to production
|
||||
├── create_test_db.php ❌ Test fixture in root
|
||||
└── Database.php ✓ OK
|
||||
```
|
||||
|
||||
## How Professional Projects Work
|
||||
|
||||
### 1. Composer Configuration
|
||||
|
||||
**composer.json** - Proper setup:
|
||||
```json
|
||||
{
|
||||
"require": {
|
||||
"php": "^7.4|^8.0"
|
||||
},
|

"phpunit/phpunit": "^9.5",
|
||||
"symfony/var-dumper": "^6.0"
|
||||
},
|
||||
"autoload": {
|

```
|

|
||||
**Key points:**
|
||||
- `require`: Production dependencies
|
||||
- `require-dev`: Development/testing dependencies (not deployed)
|
||||
- `autoload-dev`: Test autoloading (not in production)
|
||||
- `scripts`: Convenient test commands
|
||||
|
||||
### 2. PHPUnit Configuration
|
||||
|
||||
**phpunit.xml** - Test configuration:
|
||||
```xml
|
||||
<?xml version="1.0" encoding="UTF-8"?>
|
||||
<phpunit bootstrap="vendor/autoload.php"
|
||||
colors="true"
|
||||
verbose="true">
|
||||
<testsuites>
|
||||
<testsuite name="Unit">
|
||||
<directory>tests/Unit</directory>
|
||||
</testsuite>
|
||||
<testsuite name="Integration">
|
||||
<directory>tests/Integration</directory>
|
||||
</testsuite>
|
||||
<testsuite name="Security">
|
||||
<directory>tests/Security</directory>
|
||||
</testsuite>
|
||||
</testsuites>
|
||||
<coverage>
|
||||
<include>
|
||||
<directory suffix=".php">src</directory>
|
||||
</include>
|
||||
<exclude>
|
||||
<directory>vendor</directory>
|
||||
<directory>tests</directory>
|
||||
</exclude>
|
||||
</coverage>
|
||||
</phpunit>
|
||||
```
|
||||
|
||||
### 3. Example PHPUnit Test
|
||||
|
||||
**tests/Unit/DatabaseTest.php**:
|
||||
```php
|
||||
<?php
|
||||
|
||||
namespace Tests\Unit;
|
||||
|
||||
use PHPUnit\Framework\TestCase;
|
||||
use Database;
|
||||
|
||||
class DatabaseTest extends TestCase
|
||||
{
|
||||
private $db;
|
||||
|
||||
protected function setUp(): void
|
||||
{
|
||||
$this->db = Database::getInstance();
|
||||
}
|
||||
|
||||
public function testGetPublishedTheses()
|
||||
{
|
||||
$results = $this->db->getPublishedTheses(10, 0);
|
||||
|
||||
$this->assertIsArray($results);
|
||||
$this->assertLessThanOrEqual(10, count($results));
|
||||
}
|
||||
|
||||
public function testSearchThesesWithWildcard()
|
||||
{
|
||||
$results = $this->db->searchTheses(['query' => '%'], 10, 0);
|
||||
|
||||
// Should return 0 results (wildcards are escaped)
|
||||
$this->assertCount(0, $results);
|
||||
}
|
||||
|
||||
public function testSearchThesesRejectsLongInput()
|
||||
{
|
||||
$this->expectException(\InvalidArgumentException::class);
|
||||
$this->expectExceptionMessage('Search query too long');
|
||||
|
||||
$longQuery = str_repeat('a', 201);
|
||||
$this->db->searchTheses(['query' => $longQuery]);
|
||||
}
|
||||
|
||||
public function testSearchThesesRejectsInvalidYear()
|
||||
{
|
||||
$this->expectException(\InvalidArgumentException::class);
|
||||
$this->expectExceptionMessage('Invalid year');
|
||||
|
||||
$this->db->searchTheses(['year' => 999999]);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Running Tests
|
||||
|
||||
```bash
|
||||
# Install dependencies (including dev dependencies)
|
||||
composer install
|
||||
|
||||
# Run all tests
|
||||
composer test
|
||||
# or
|
||||
./vendor/bin/phpunit
|
||||
|
||||
# Run specific test suite
|
||||
./vendor/bin/phpunit --testsuite Unit
|
||||
|
||||
# Run specific test file
|
||||
./vendor/bin/phpunit tests/Unit/DatabaseTest.php
|
||||
|
||||
# Run with coverage report
|
||||
composer test:coverage
|
||||
```
|
||||
|
||||
### 5. .gitignore Configuration
|
||||
|
||||
**.gitignore**:
|
||||
```
|
||||
# Dependencies
|
||||
/vendor/
|
||||
|
||||
# Test artifacts
|
||||
/coverage/
|
||||
/.phpunit.cache/
|
||||
/phpunit.xml.local
|
||||
|
||||
# Cache
|
||||
/cache/
|
||||
|
||||
# Environment
|
||||
.env
|
||||
.env.local
|
||||
|
||||
# IDE
|
||||
/.idea/
|
||||
/.vscode/
|
||||
*.swp
|
||||
|
||||
# OS
|
||||
.DS_Store
|
||||
Thumbs.db
|
||||
|
||||
# Logs
|
||||
*.log
|
||||
error.log
|
||||
```
|
||||
|
||||
**Important:** Tests themselves ARE committed to git, but:
|
||||
- `vendor/` is excluded (regenerated via `composer install`)
|
||||
- Test coverage reports are excluded
|
||||
- Cache is excluded
|
||||
|
||||
## Production Deployment
|
||||
|
||||
### What Gets Deployed
|
||||
|
||||
```bash
|
||||
# Option 1: composer install without dev dependencies
|
||||
composer install --no-dev --optimize-autoloader
|
||||
|
||||
# This installs ONLY 'require' packages, NOT 'require-dev'
|
||||
# Result: No PHPUnit, no test dependencies
|
||||
```
|
||||
|
||||
**Deployed:**
|
||||
- Application code (`src/` or root PHP files)
|
||||
- Production dependencies (`vendor/` - only `require`)
|
||||
- Public assets (`public/`, `assets/`)
|
||||
|
||||
**NOT Deployed:**
|
||||
- `tests/` directory (excluded via deployment config)
|
||||
- Dev dependencies (PHPUnit, etc.)
|
||||
- `cache/` directory
|
||||
- `.git/` directory
|
||||
|
||||
### Deployment Configurations
|
||||
|
||||
**Option 1: .deployignore** (custom deploy scripts):
|
||||
```
|
||||
/tests/
|
||||
/coverage/
|
||||
/.git/
|
||||
/.github/
|
||||
/cache/
|
||||
phpunit.xml
|
||||
phpunit.xml.dist
|
||||
.env.example
|
||||
README*.md
|
||||
*.md
|
||||
```
|
||||
|
||||
**Option 2: rsync with excludes** (like your justfile):
|
||||
```bash
|
||||
rsync -avz \
|
||||
--exclude 'tests/' \
|
||||
--exclude 'coverage/' \
|
||||
--exclude 'cache/' \
|
||||
--exclude '.git/' \
|
||||
--exclude 'phpunit.xml' \
|
||||
--exclude '*.md' \
|
||||
./ server:/var/www/html/
|
||||
```
|
||||
|
||||
**Option 3: Build artifact** (best for large projects):
|
||||
```bash
|
||||
# Build step
|
||||
composer install --no-dev --optimize-autoloader
|
||||
# Creates clean vendor/ with only production deps
|
||||
|
||||
# Then deploy only necessary files
|
||||
```
|
||||
|
||||
## Continuous Integration (CI/CD)
|
||||
|
||||
Professional projects run tests automatically:
|
||||
|
||||
**GitHub Actions** (.github/workflows/tests.yml):
|
||||
```yaml
|
||||
name: Tests
|
||||
|
||||
on: [push, pull_request]
|
||||
|
||||
jobs:
|
||||
test:
|
||||
runs-on: ubuntu-latest
|
||||
steps:
|
||||
- uses: actions/checkout@v2
|
||||
|
||||
- name: Setup PHP
|
||||
uses: shivammathur/setup-php@v2
|
||||
with:
|
||||
php-version: '8.1'
|
||||
|
||||
- name: Install dependencies
|
||||
run: composer install --prefer-dist --no-progress
|
||||
|
||||
- name: Run tests
|
||||
run: composer test
|
||||
|
||||
- name: Check security
|
||||
run: ./vendor/bin/phpunit --testsuite Security
|
||||
```
|
||||
|
||||
## Test Types
|
||||
|
||||
### Unit Tests
|
||||
Test individual methods in isolation:
|
||||
```php
|
||||
public function testEscapeLikeString()
|
||||
{
|
||||
$db = new Database();
|
||||
$reflection = new ReflectionClass($db);
|
||||
$method = $reflection->getMethod('escapeLikeString');
|
||||
$method->setAccessible(true);
|
||||
|
||||
$result = $method->invoke($db, 'test%value_here');
|
||||
$this->assertEquals('test\%value\_here', $result);
|
||||
}
|
||||
```
|
||||
|
||||
### Integration Tests
|
||||
Test multiple components together:
|
||||
```php
|
||||
public function testSearchWithMultipleFilters()
|
||||
{
|
||||
$db = Database::getInstance();
|
||||
$results = $db->searchTheses([
|
||||
'query' => 'urbain',
|
||||
'year' => 2024,
|
||||
'orientation' => 'Arts Numériques'
|
||||
]);
|
||||
|
||||
$this->assertNotEmpty($results);
|
||||
foreach ($results as $result) {
|
||||
$this->assertEquals(2024, $result['year']);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Security Tests
|
||||
Test security measures:
|
||||
```php
|
||||
public function testSqlInjectionPrevention()
|
||||
{
|
||||
$db = Database::getInstance();
|
||||
|
||||
// These should not cause errors or expose data
|
||||
$malicious = ["' OR 1=1--", "'; DROP TABLE theses;--"];
|
||||
|
||||
foreach ($malicious as $injection) {
|
||||
$results = $db->searchTheses(['query' => $injection]);
|
||||
// Treated as literal strings, returns valid results or empty
|
||||
$this->assertIsArray($results);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Comparison: Current vs. Standard
|
||||
|
||||
| Aspect | Current Approach | Standard Approach |
|
||||
|--------|------------------|-------------------|
|
||||
| **Location** | Root directory | `tests/` directory |
|
||||
| **Framework** | Raw PHP scripts | PHPUnit |
|
||||
| **Naming** | `test_*.php` | `*Test.php` |
|
||||
| **Running** | `php test_file.php` | `composer test` |
|
||||
| **CI/CD** | Manual | Automated |
|
||||
| **Production** | Must manually exclude | Auto-excluded |
|
||||
| **Coverage** | None | Built-in reporting |
|
||||
| **Assertions** | Manual echoing | PHPUnit assertions |
|
||||
|
||||
## Migration Path for Your Project
|
||||
|
||||
### Minimal Changes (Keep it Simple)
|
||||
|
||||
If you want to keep the current simple approach but make it safer:
|
||||
|
||||
1. **Move tests to `tests/` directory:**
|
||||
```bash
|
||||
mkdir tests
|
||||
mv test_*.php tests/
|
||||
mv create_test_db.php tests/fixtures/
|
||||
```
|
||||
|
||||
2. **Update justfile to exclude tests:**
|
||||
```just
|
||||
deploy:
|
||||
rsync -vur --progress \
|
||||
--exclude 'tests/' \
|
||||
--exclude 'cache/' \
|
||||
--exclude '*.db' \
|
||||
./front-backend/ server:/var/www/html/
|
||||
```
|
||||
|
||||
3. **Add .gitignore:**
|
||||
```
|
||||
/cache/
|
||||
/vendor/
|
||||
*.log
|
||||
test.db
|
||||
```
|
||||
|
||||
### Recommended Approach (Industry Standard)
|
||||
|
||||
For a more professional setup:
|
||||
|
||||
1. **Install PHPUnit:**
|
||||
```bash
|
||||
composer require --dev phpunit/phpunit
|
||||
```
|
||||
|
||||
2. **Convert tests to PHPUnit** (I can help with this)
|
||||
|
||||
3. **Add phpunit.xml configuration**
|
||||
|
||||
4. **Update deployment to use `composer install --no-dev`**
|
||||
|
||||
## Benefits of Standard Approach
|
||||
|
||||
1. **Automatic Exclusion**: Tests never deployed by accident
|
||||
2. **Better Assertions**: PHPUnit provides rich assertion library
|
||||
3. **Coverage Reports**: See which code is tested
|
||||
4. **CI/CD Integration**: Automated testing on every commit
|
||||
5. **IDE Support**: Better integration with PHPStorm, VSCode
|
||||
6. **Mocking**: Easy to mock dependencies
|
||||
7. **Data Providers**: Test same logic with multiple inputs
|
||||
8. **Professional**: Expected by other developers
|
||||
|
||||
## Quick Decision Guide
|
||||
|
||||
**Keep Simple Approach If:**
|
||||
- ✓ Small project (< 10 files)
|
||||
- ✓ Solo developer
|
||||
- ✓ No CI/CD pipeline
|
||||
- ✓ You manually test before deploy
|
||||
|
||||
**Use PHPUnit If:**
|
||||
- ✓ Team project
|
||||
- ✓ Growing codebase
|
||||
- ✓ Want automated testing
|
||||
- ✓ Need coverage reports
|
||||
- ✓ Planning CI/CD
|
||||
|
||||
## Recommendation for Your Project
|
||||
|
||||
Given your project size, I'd suggest a **hybrid approach**:
|
||||
|
||||
1. **Move tests to `tests/` directory** (immediate)
|
||||
2. **Update deployment to exclude `tests/`** (immediate)
|
||||
3. **Keep simple PHP test scripts for now** (works fine)
|
||||
4. **Migrate to PHPUnit later** (when project grows)
|
||||
|
||||
