# PackIt

PackIt is a smart packing list generator for outdoor activities. Select the activities you're planning — camping, skiing, kayaking, and more — and PackIt produces a deduplicated, grouped checklist of everything you need to bring.

## How it works

1. **Choose your activities** — Pick one or more activities from the activity selection page. Activities are organised into groups (e.g. Overnight, Water Activities, Winter Sports).
2. **Generate your list** — PackIt merges all item requirements across your selected activities, removing duplicates, and groups the result by category (Clothing, Shelter, Navigation, etc.).
3. **Pack and check off** — Work through the interactive checklist, ticking items as you pack them. A progress bar tracks how far along you are.
4. **Share or print** — Every list gets a permanent, shareable URL. You can also print the list directly from the browser.

## Features

- **Activity-based list generation** — Items are mapped to activities in the database. Selecting multiple activities produces a single merged list with no duplicate entries.
- **Grouped items** — Items are organised into logical categories (Clothing, Shelter, Navigation, Medical, Water & Food, Safety Gear) for easy scanning.
- **Interactive checklist** — Click any item to mark it as packed. Checked items are visually struck through and a progress bar updates in real time.
- **Shareable URLs** — Each unique activity selection is stored with a SHA-256 hash and accessible via a permanent link you can send to teammates or trip partners.
- **Print support** — The packing list page has a print stylesheet that removes UI chrome and renders a clean black-and-white checklist.
- **Admin panel** — A password-protected admin interface at `/admin/` lets you manage all content:
  - Activity groups and activities
  - Item groups and items
  - Activity-to-item mappings
  - Dashboard with counts of all entities

## Tech stack

- **Backend:** PHP with PDO
- **Database:** MySQL (schema in `schema.sql`)
- **Frontend:** Vanilla HTML/CSS/JS — no build step required

## Setup

1. Create the database by running `schema.sql`:
   ```
   mysql -u <user> -p < schema.sql
   ```
2. Copy `config.php` and set your database credentials.
3. Serve the project with any PHP-capable web server (Apache, Nginx, PHP built-in server).
4. Open the site in a browser and start selecting activities.
