Théophile Gervreau-Mercier 8613f71112 security: add PHP session auth guard for admin panel (item #2, CRITICAL)
- lib/AdminAuth.php: new class with requireLogin(), login(), logout(),
  isAuthenticated(); starts session with hardened cookie params
  (HttpOnly, SameSite=Strict, Secure, Path=/admin) — also resolves
  item #8 (session cookie hardening)
- requireLogin() auto-authenticates from nginx Basic Auth credentials
  ($_SERVER['PHP_AUTH_PW']) so the user only sees one browser prompt;
  falls back to /admin/login.php if the proxy is absent/misconfigured
- config/admin_credentials.php: gitignored credential store; define
  ADMIN_PASSWORD_HASH with a bcrypt hash to enable PHP auth
- config/admin_credentials.example.php: template for the above
- config/bootstrap.php: auto-loads admin_credentials.php if present
- .gitignore: exclude config/admin_credentials.php
- public/admin/login.php: fallback login form (shown only when nginx
  Basic Auth is bypassed / proxy absent)
- public/admin/logout.php: session destruction + redirect to login
- All 7 admin PHP files: replace session_start() with
  AdminAuth::requireLogin() (defence-in-depth behind nginx Basic Auth)
- public/admin/inc/head.php: Déconnexion button when ADMIN_PASSWORD_HASH
  is defined
- nginx/PHP_AUTH_LAYER.md: documents dual-auth architecture, UX flow,
  and setup instructions
- docs/TODO.SECURITY.md: items #2 and #8 moved to Resolved; priority
  order updated (all CRITICAL done)

# Admin Panel Structure
This directory contains the admin panel for managing Post-ERG thesis database.
## Directory Structure
```
public/admin/
├── index.php # List all theses (main page)
├── add.php # Add new thesis form
├── edit.php # Edit existing thesis form
├── import.php # CSV import form
├── thanks.php # Thank you page after submission
├── actions/ # Backend processing scripts (no HTML output)
│ ├── formulaire.php # Process thesis submission from add.php
│ └── publish.php # Toggle publish/unpublish status
├── inc/ # Shared templates
│ ├── head.php # HTML head, CSS, navigation
│ └── footer.php # HTML footer
└── data/ # Upload directory (not in git)
├── theses/ # PDF files
└── covers/ # Cover images
```
## File Types
### User-Facing Templates (Root Directory)
Files that display HTML to users:
- **index.php** - Lists all theses with filters and bulk actions
- **add.php** - Form to add a new thesis
- **edit.php** - Form to edit an existing thesis
- **import.php** - CSV import interface
- **thanks.php** - Success confirmation page
### Backend Scripts (actions/)
Files that process forms and redirect (no HTML output):
- **formulaire.php** - Processes thesis submission from add.php
- **publish.php** - Handles publish/unpublish actions
### Shared Templates (inc/)
Reusable HTML components:
- **head.php** - HTML head, CSS links, navigation menu
- **footer.php** - HTML footer
## Workflow
### Adding a Thesis
1. User visits `add.php` (displays form)
2. User submits form to `actions/formulaire.php` (processes data)
3. On success, redirects to `thanks.php?id=123`
4. On error, redirects back to `add.php` with error message
### Publishing/Unpublishing
1. User clicks publish/unpublish button in `index.php`
2. Form submits to `actions/publish.php` (processes action)
3. Redirects back to `index.php` with success/error message
## Security
- All pages require HTTP Basic Auth (configured in nginx) — primary layer
- All pages require PHP session auth (`AdminAuth::requireLogin()`) — defence-in-depth
- CSRF tokens protect all forms
- File uploads validated and sanitized
- Database queries use prepared statements
- Upload directory outside public/ in production
See `nginx/PHP_AUTH_LAYER.md` for details on the dual-auth architecture.
## Templates
The `inc/` folder contains shared templates:
- `head.php` - Included at the top of each page (DOCTYPE, CSS, nav)
- `footer.php` - Included at the bottom of each page (closing tags)
Usage:
```php
<?php include "inc/head.php" ?>
<!-- Page content here -->
<?php include "inc/footer.php" ?>
```
## URL Structure
- `/admin/` - List theses (index.php)
- `/admin/add.php` - Add new thesis
- `/admin/edit.php?id=123` - Edit thesis #123
- `/admin/import.php` - Import CSV
- `/admin/thanks.php?id=123` - Thank you page
Backend actions (not directly accessed):
- `/admin/actions/formulaire.php` - Form processor
- `/admin/actions/publish.php` - Publish toggle
## Development
### Adding a New Page
1. Create the template in `/admin/yourpage.php`:
```php
<?php
require_once __DIR__ . "/../../config/bootstrap.php";
require_once __DIR__ . '/../../lib/AdminAuth.php';
AdminAuth::requireLogin();
$pageTitle = "Your Page Title";
?>
<?php include "inc/head.php" ?>
<!-- Your content here -->
<?php include "inc/footer.php" ?>
```
2. Add navigation link in `inc/head.php` if needed
### Adding a New Action
1. Create the script in `/admin/actions/youraction.php`:
```php
<?php
require_once __DIR__ . "/../../config/bootstrap.php";
require_once __DIR__ . '/../../lib/AdminAuth.php';
AdminAuth::requireLogin();
// Verify CSRF token
if (!hash_equals($_SESSION['csrf_token'], $_POST['csrf_token'])) {
$_SESSION['error'] = "Security error";
header('Location: ../index.php');
exit;
}
// Process action...
// Redirect
header('Location: ../yourpage.php');
exit;
```
2. Create form in template that posts to `actions/youraction.php`
## Notes
- Bootstrap path from actions/: `__DIR__ . "/../../config/bootstrap.php"`
- Redirects from actions/: use `../` prefix (e.g., `../index.php`)
- Database class: `require_once __DIR__ . '/../../lib/Database.php'`
- All forms must include CSRF token from `$_SESSION['csrf_token']`
