Introduction

The hCaptcha is a human-computer verification solution that replaces Google reCaptcha. It has high performance, high availability and high recognition, especially suitable for regions with poor network quality, such as East Asia, Middle East, etc. Many well-known companies are using the hCaptcha solution.

The package is one of the recommended package on the official developer guide of HCaptcha. No malicious code, ensuring the security of your development supply chain.

  • Purchase a VPS or Akamai VPS for developing and deploying applications.

Installation

composer require scyllaly/hcaptcha

Laravel 5 and above

Setup

In app/config/app.php add the following :

Step 1: The ServiceProvider to the providers array :

Scyllaly\HCaptcha\HCaptchaServiceProvider::class,

Step 2: The class alias to the aliases array :

'HCaptcha' => Scyllaly\HCaptcha\Facades\HCaptcha::class,

Step 3: Publish the config file

php artisan vendor:publish --provider="Scyllaly\HCaptcha\HCaptchaServiceProvider"

Usage

Init js source

With default options :

 {!! HCaptcha::renderJs() !!}

With language support or onloadCallback option :

 {!! HCaptcha::renderJs('fr', true, 'hcaptchaCallback') !!}

Display hCaptcha

Default widget :

{!! HCaptcha::display() !!}

With custom attributes (theme, size, callback ...) :

{!! HCaptcha::display(['data-theme' => 'dark']) !!}

Invisible hCaptcha 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|HCaptcha' to rules array :

$validate = Validator::make(Input::all(), [
	'h-captcha-response' => 'required|HCaptcha'
]);
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.',
        'h_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 `h-captcha-response`
$response = $this->json('POST', '/register', [
    'h-captcha-response' => '1',
    'name' => 'Scyllaly',
    'email' => '[email protected]',
    'password' => '123456',
    'password_confirmation' => '123456',
]);

Without Laravel

Checkout example below:

<?php

require_once "vendor/autoload.php";

$secret  = 'CAPTCHA-SECRET';
$sitekey = 'CAPTCHA-SITEKEY';
$captcha = new \Scyllaly\HCaptcha\HCaptcha($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(); ?>
