# Captcha for Laravel 4
A simple [Laravel 4](http://four.laravel.com/) service provider for including the [Captcha for Laravel 4](https://github.com/sayakb/captcha).
## Preview
## Installation
The Captcha Service Provider can be installed via [Composer](http://getcomposer.org) by requiring the
`sayakb/captcha` package and setting the `minimum-stability` to `dev` (required for Laravel 4) in your
project's `composer.json`.
```json
{
"require": {
"laravel/framework": "4.1.*",
"sayakb/captcha": "dev-master"
},
"minimum-stability": "dev"
}
```
Update your packages with ```composer update``` or install with ```composer install```.
## Usage
To use the Captcha Service Provider, you must register the provider when bootstrapping your Laravel application. There are
essentially two ways to do this.
Find the `providers` key in `app/config/app.php` and register the Captcha Service Provider.
```php
'providers' => array(
// ...
'Sayakb\Captcha\CaptchaServiceProvider',
)
```
Find the `aliases` key in `app/config/app.php`.
```php
'aliases' => array(
// ...
'Captcha' => 'Sayakb\Captcha\Facades\Captcha',
)
```
## Configuration
To use your own settings, publish config.
```$ php artisan config:publish sayakb/captcha```
## Example Usage
```php
// [your site path]/app/routes.php
Route::any('/captcha-test', function()
{
if (Request::getMethod() == 'POST')
{
$rules = array('captcha' => array('required', 'captcha'));
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails())
{
echo '<p style="color: #ff0000;">Incorrect!</p>';
}
else
{
echo '<p style="color: #00ff30;">Matched :)</p>';
}
}
$content = Form::open(array(URL::to(Request::segment(1))));
$content .= '<p>' . HTML::image(Captcha::img(), 'Captcha image') . '</p>';
$content .= '<p>' . Form::text('captcha') . '</p>';
$content .= '<p>' . Form::submit('Check') . '</p>';
$content .= '<p>' . Form::close() . '</p>';
return $content;
});
```
