reCAPTCHA for the Laravel framework

This is a bundle of the reCAPTCHA library now developed by Google. This bundle will allow you to validate captchas using the reCAPTCHA API. Please note that this is for the server-side validation only!

Please see the reCAPTCHA Introduction on the Google Developers website for help with getting the client-side configured as well as any customization you may wish to do.

Installation

Install reCAPTCHA via Artisan:

php artisan bundle:install recaptcha

Add the following to your application/bundles.php file:

'recaptcha' => array('auto' => true);

reCATPCHA registers a validation rule (validate_recaptcha) to your custom validators in its start.php file.

Usage

This bundle is designed to be used with Laravels validator but it can just as easily be used as a standalone class.
Here is an example validation method:

$rules = array(
    'recaptcha_response_field' => 'recaptcha:RECAPTCHA_PRIVATE_KEY'
);

$validator = Validator::make($input, $rules);

if($validator->valid())
{
    // reCAPTCHA was entered correctly
}

Remember you'll need to get your public and private keys by signing up above.

If you'd prefer to check a captcha without using the Validator you can simply try the following:

$recaptcha = Recaptcha\Recaptcha::recaptcha_check_answer('RECAPTCHA_PRIVATE_KEY', Laravel\Request::ip(), Laravel\Input::get('recaptcha_challenge_field'), Laravel\Input::get('recaptcha_response_field'));

if($recaptcha->is_valid)
{
    // reCAPTCHA was entered correctly
}

Further Information

This bundle just uses the PHP class from the reCAPTCHA library. If you have any further questions try looking through the reCAPTCHA documentation on the Google Developers website.
