Chess Captcha
=============

[](#chess-captcha)

##### Requirements: php >= 5.4, jquery > 1.8 | Latest Version 2.0.2

[](#requirements-php--54-jquery--18--latest-version-202)

This is a captcha system where the user either recreates the position of the pieces on the board - *non chess savvy users* - or she solves a mate-in-one puzzle by putting the piece on the square where it gives the checkmate - *chess savvy users only*. There is also a no js fallback that exists mostly as a placeholder for future iterations; don't use it. Chesscaptcha was built for fun, it is a work in progress so feel free to make pull requests and contribute!

Implementation:
===============

[](#implementation)

#### Through Composer

[](#through-composer)

```
composer require elioair/chesscaptcha

```

After composer finishes importing the package:

- You may remove the `/vendor/elioair/chesscaptcha/examples` directory
- Place the `/vendor/elioair/chesscaptcha/assets` directory or it's contents where it suits your project. **Note** that the image files are used both by the `js` client and the `php` server side.
- Fix the image paths in the `/vendor/elioair/chesscaptcha/src/ChessCaptcha/BoardImageCreator.php`

#### Directly cloning the repo

[](#directly-cloning-the-repo)

Clone the repository and see immediately how it works by going to the `/examples` folder. You might need to `require_once` the files of the classes involved in the class files in the `src/ChessCaptcha` folder.

*Quick tip: run `composer install` and then `composer dump-autoload --optimize` and include the loader.*

**Working Example:** `/examples/chesscaptcha-example.php`
