## About

Easy-to-use Facebook login wrapper for [`Nette Framework`](https://github.com/nette/).

## Installation

```bash
composer require contributte/facebook
```

## Setup

```neon
extensions:
	facebook: Contributte\Facebook\DI\Nette\FacebookExtension
```

If you are using PHP 8.0+, you need to use forked version of `facebook/graph-sdk`. You can rely on our fork [holyfork/facebook-graph-sdk](https://github.com/holyfork/facebook-graph-sdk), it's tested and working.

```json
{
  "repositories": [
    { "type": "git", "url": "https://github.com/holyfork/facebook-graph-sdk" }
  ]
}
```

## Configuration

You need to create a FacebookApp and supply these parameters:

* **appId**
* **appSecret**
* **defaultGraphVersion** (optional)
* **persistentDataHandler** (optional) default value: **session**
* **httpClientHandler** (optional)

```neon
facebook:
	appId: %yourAppId%
	appSecret: %yourAppSecret%
```

## Usage

Simple example how to use Facebook Login in Presenter

```php
namespace App\Presenters;

use Contributte\Facebook\Exceptions\FacebookLoginException;
use Contributte\Facebook\FacebookLogin;
use Nette\Application\Responses\RedirectResponse;
use Nette\Application\UI\Presenter;
use Nette\Security\AuthenticationException;

final class SignPresenter extends Presenter
{

/** @var FacebookLogin @inject */
	public $facebookLogin;

public function actionFacebook()
	{
		// Redirect to FB and ask customer to grant access to his account
		$url = $this->facebookLogin->getLoginUrl($this->link('//facebookAuthorize'), ['email', 'public_profile']);
		$this->sendResponse(new RedirectResponse($url));
	}

/**
	 * Log in user with accessToken obtained after redirected from FB
	 *
	 * @return void
	 */
	public function actionFacebookAuthorize()
	{
		// Fetch User data from FB and try to login
		try {
			$token = $this->facebookLogin->getAccessToken();

$this->user->login('facebook', $this->facebookLogin->getMe($token->getValue(), ['first_name', 'last_name', 'email', 'gender']));
			$this->flashMessage('Login successful :-).', 'success');
		} catch (FacebookLoginException | AuthenticationException $e) {
			$this->flashMessage('Login failed. :-( Try again.', 'danger');
		}
	}

}

```

If you need to specify your own state param (more info [here](https://developers.facebook.com/docs/facebook-login/security/#stateparam) mind also checking Enable Strict Mode). `Facebook::getLoginUrl()` takes optional third parameter `$stateParam` which FB passes back unchanged.

## JavaScript Login

You can also use FB login button, for example:

```html
<div
    class="fb-login-button"
    onlogin="fbAfterLogin()"
    data-width="200"
    data-max-rows="1"
    data-size="medium"
    data-button-type="continue_with"
    data-show-faces="false"
    data-auto-logout-link="false"
    data-use-continue-as="true"
    data-scope="email,public_profile"
>
Login
</div>
```

And use `onlogin` event to call backend code which takes care of registration/login process:

```php
/**
 * Log in user with accessToken from cookie/session after javascript authorization
 */
public function actionFacebookCookie()
{
	// Fetch User data from FB and try to login
	try {
		$token = $this->facebookLogin->getAccessTokenFromCookie();

$this->user->login('facebook', $this->facebookLogin->getMe($token, ['first_name', 'last_name', 'email', 'gender']));
		$this->flashMessage('Login successful :-).', 'success');
	} catch (FacebookLoginException | AuthenticationException $e) {
		$this->flashMessage('Login failed. :-( Try again.', 'danger');
	}
}
```
