Display reCAPTCHA

{!! app('captcha')->display($attributes) !!}

OR use Facade: add 'Captcha' => '\Buzz\LaravelGoogleCaptcha\CaptchaFacade', to the aliases array in config/app.php and in template use:

{!! Captcha::display($attributes) !!}

OR use Form

{!! Form::captcha($attributes) !!}

With custom language support:

{!! app('captcha')->display($attributes = [], $options = ['lang'=> 'vi']) !!}

With

// element attributes
$attributes = [
    'data-theme' => 'dark',
    'data-type' => 'audio',
];

// package options
$options = [
    'data-theme' => 'dark',
    'data-type'	=> 'audio',
];

Validation

Add 'g-recaptcha-response' => 'required|captcha' to rules array.

use Validator;
use Illuminate\Support\Facades\Input;

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

Testing

When using the Laravel Testing functionality, you will need to mock out the response for the captcha form element. For any form tests involving the captcha, you can then mock the facade behaviour:

// Prevent validation error on captcha
        CaptchaFacade::shouldReceive('verify')
            ->andReturn(true);
            
// Provide hidden input for your 'required' validation
        CaptchaFacade::shouldReceive('display')
            ->andReturn('<input type="hidden" name="g-recaptcha-response" value="1" />');
            
// Add these when testing multiple captchas on a single page
        CaptchaFacade::shouldReceive('displayJs');
        CaptchaFacade::shouldReceive('displayMultiple');
        CaptchaFacade::shouldReceive('multiple');
