1. User Authentication – Login /login & Register /register with password hashing. Pre‑seeded demo accounts (password: password).
2. Session Creation – Any user can start a food session, paste menu items, and invite colleagues.
3. Self‑Ordering – Browse active sessions, select multiple items, set quantities and notes.
4. Bill Calculation – Host enters final prices, app computes each participant’s bill and generates copy‑ready markdown.

How to Run (SQLite)

Option 1: PHP Built‑in Server

php -S localhost:8000 -t public

Visit http://localhost:8000.

Option 2: Docker Compose

docker compose up -d --build

Visit http://localhost:8080.

Option 3: Apache

Point the VirtualHost DocumentRoot to the public/ directory (rewrites handled by public/.htaccess).

Database Setup (SQLite)

1. Copy the example env file and set SQLite configuration:

cp .env.example .env

Edit .env:

DB_CONNECTION=sqlite
DB_DATABASE=storage/database.sqlite

2. Create the SQLite file and run the schema initialization (executed automatically on first request):

mkdir -p storage
touch storage/database.sqlite
php -r "require 'public/index.php'; App\\Core\\Database\\Database::initSchema();"

The initSchema() method creates all tables and seeds initial data if the database is empty.

Resetting Data

To start from a clean slate:

rm storage/database.sqlite
mkdir -p storage
touch storage/database.sqlite
php -r "require 'public/index.php'; App\\Core\\Database\\Database::initSchema();"

Or invoke the built‑in reset:

php -r "require 'public/index.php'; App\\Core\\Database\\Database::initSchema();"

(Calling initSchema() drops existing tables and recreates them.)

Troubleshooting

• Missing PDO SQLite extension – Install via sudo apt-get install php8.2-sqlite3.
• File permission issues – Ensure the web server user can read/write storage/.
• Database connection errors – Verify .env settings and that storage/database.sqlite exists.

Key Features

1. User Authentication (Zero Framework):

   • Login (/login) & Register (/register) with secure password hashing (password_hash()).
   • Pre-seeded test accounts (Password: password):
     • dea (Dea - Coordinator)
     • alex (Alex Turner)
     • sarah (Sarah Jenkins)
     • budi (Budi Santoso)
     • michael (Michael Chen)
   • 1-click Quick Demo Account switcher on login page.

2. Session Creation by Anyone:

   • Any team member can click "➕ Start a Food Session" to coordinate canteen lunch, boba/coffee runs, or snack orders.
   • Hosts paste today's menu choices directly from chat (no prices needed upfront).

3. Self-Ordering from Any Session:

   • Logged-in colleagues browse all active sessions on the dashboard.
   • Multi-Select Interactive Menu: Click multiple items, adjust quantities (+ / -), and add specific notes ("no spicy", "extra egg").
   • The app automatically assigns the order to the authenticated coworker.

4. Grouped Canteen Placement & Bill Settlement:

   • 1-Click "Copy Canteen Text" aggregates quantities into a formatted WhatsApp/chat message.
   • When food arrives with the receipt, the host enters the final prices per item.
   • The app automatically computes every coworker's personal bill!
   • 1-Click "Copy Mattermost Breakdown" generates a ready-to-paste markdown table tagging @coworker with their exact individual bill and payment status (Unpaid / Paid).
