# CanteenHub - Multi-User Collaborative Canteen & Food Ordering System

A zero-framework PHP application built to replace informal Mattermost/chat lunch ordering threads. Anyone on the team can log in, start a food session, join any colleague's session, and place their own orders with automatic bill calculation upon food arrival.

## 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`).
