Usage

Render JS
```
{!! Recaptcha::renderJs() !!}
```
Create Recaptcha field

this is a hidden input field that gets filled with a recaptcha token.
```
{!! Recaptcha::field('login') !!}
```

Validate

$validate = Validator::make(Input::all(), [
   'g-recaptcha-response' => 'required|recaptcha:login'
]);

Done

Custom Validation Message

Add the following values to the custom array in the validation language file:

'custom' => [     
    'g-recaptcha-response' => [
        'required' => 'Please verify that you are not a robot.',
        'recaptcha' => 'Captcha error! try again later or contact site admin.',
    ],
],

Then check for captcha errors in the Form:

@if ($errors->has('g-recaptcha-response'))
    <p>{{ $errors->first('g-recaptcha-response') }}</p>
@endif

Validate Score Manually

Alternatively, you can get the score and take variable action:

$token = $request->get('g-recaptcha-response');
$action = 'home';
$score = 0;

$score = app('recaptcha')->verify($token, $action, $score);

if($score > 0.7) {
    // is valid
} 
else if($score > 0.3) {
    // require additional email verification
} 
else {
    return abort(400, 'Bad request');
}
