Usage
Init js source
With default options :
{!! HCaptcha::renderJs() !!}
With language support or onloadCallback option :
{!! HCaptcha::renderJs('fr', true, 'recaptchaCallback') !!}
Display reCAPTCHA
Default widget :
{!! HCaptcha::display() !!}
With custom attributes (theme, size, callback ...) :
{!! HCaptcha::display(['data-theme' => 'dark']) !!}
Invisible reCAPTCHA using a submit button:
{!! HCaptcha::displaySubmit('my-form-id', 'submit now!', ['data-theme' => 'dark']) !!}
Notice that the id of the form is required in this method to let the autogenerated callback submit the form on a successful captcha verification.
Validation
Add 'h-captcha-response' => 'required|captcha'
to rules array :
$validate = Validator::make(Input::all(), [ 'h-captcha-response' => 'required|captcha' ]);
Custom Validation Message
Add the following values to the custom
array in the validation
language file :
'custom' => [ 'h-captcha-response' => [ 'required' => 'Please verify that you are not a robot.', 'captcha' => 'Captcha error! try again later or contact site admin.', ], ],
Then check for captcha errors in the Form
:
@if ($errors->has('h-captcha-response')) <span class="help-block"> <strong>{{ $errors->first('h-captcha-response') }}</strong> </span> @endif
Testing
When using the Laravel Testing functionality, you will need to mock out the response for the captcha form element.
So for any form tests involving the captcha, you can do this by mocking the facade behavior:
// prevent validation error on captcha HCaptcha::shouldReceive('verifyResponse') ->once() ->andReturn(true); // provide hidden input for your 'required' validation HCaptcha::shouldReceive('display') ->zeroOrMoreTimes() ->andReturn('<input type="hidden" name="h-captcha-response" value="1" />');
You can then test the remainder of your form as normal.
When using HTTP tests you can add the h-captcha-response
to the request body for the 'required' validation:
// prevent validation error on captcha HCaptcha::shouldReceive('verifyResponse') ->once() ->andReturn(true); // POST request, with request body including g-recaptcha-response $response = $this->json('POST', '/register', [ 'h-captcha-response' => '1', 'name' => 'John', 'email' => 'john@example.com', 'password' => '123456', 'password_confirmation' => '123456', ]);
Without Laravel
Checkout example below:
<?php require_once "vendor/autoload.php"; $secret = 'CAPTCHA-SECRET'; $sitekey = 'CAPTCHA-SITEKEY'; $captcha = new \ZBrettonYe\HCaptcha\HCaptcha($secret, $sitekey); if (! empty($_POST)) { var_dump($captcha->verifyResponse($_POST['h-captcha-response'])); exit(); } ?> <form action="?" method="POST"> <?php echo $captcha->display(); ?> <button type="submit">Submit</button> </form> <?php echo $captcha->renderJs(); ?>
