https://packagist.org/packages/summergeorge/no-captcha

For Laravel 4 use v1 branch.

Installation

composer require summergeorge/no-captcha

Laravel 5

Setup

NOTE This package supports the auto-discovery feature of Laravel 5.5, So skip these Setup instructions if you're using Laravel 5.5.

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

1- The ServiceProvider to the providers array :

Summergeorge\NoCaptcha\NoCaptchaServiceProvider::class,

2- The class alias to the aliases array :

'NoCaptcha' => Summergeorge\NoCaptcha\Facades\NoCaptcha::class,

3- Publish the config file

php artisan vendor:publish --provider="Summergeorge\NoCaptcha\NoCaptchaServiceProvider"

Configuration

Add NOCAPTCHA_SECRET and NOCAPTCHA_SITEKEY in .env file :

NOCAPTCHA_SECRET=secret-key
NOCAPTCHA_SITEKEY=site-key

(You can obtain them from here)

Usage

Init js source

With default options :

 {!! NoCaptcha::renderJs() !!}

With language support or onloadCallback option :

 {!! NoCaptcha::renderJs('fr', true, 'recaptchaCallback') !!}

Display reCAPTCHA

Default widget :

{!! NoCaptcha::display() !!}

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

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

Invisible reCAPTCHA using a submit button:

{!! NoCaptcha::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 'g-recaptcha-response' => 'required|captcha' to rules array :

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

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.',
        'captcha' => 'Captcha error! try again later or contact site admin.',
    ],
],

Then check for captcha errors in the Form :

@if ($errors->has('g-recaptcha-response'))
    <span class="help-block">
        <strong>{{ $errors->first('g-recaptcha-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
NoCaptcha::shouldReceive('verifyResponse')
    ->once()
    ->andReturn(true);

// provide hidden input for your 'required' validation
NoCaptcha::shouldReceive('display')
    ->zeroOrMoreTimes()
    ->andReturn('<input type="hidden" name="g-recaptcha-response" value="1" />');

You can then test the remainder of your form as normal.

When using HTTP tests you can add the g-recaptcha-response to the request body for the 'required' validation:

// prevent validation error on captcha
NoCaptcha::shouldReceive('verifyResponse')
    ->once()
    ->andReturn(true);

// POST request, with request body including g-recaptcha-response
$response = $this->json('POST', '/register', [
    'g-recaptcha-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';
$captcha = new \Summergeorge\NoCaptcha\NoCaptcha($secret, $sitekey);

if (! empty($_POST)) {
    var_dump($captcha->verifyResponse($_POST['g-recaptcha-response']));
    exit();
}

?>

<form action="?" method="POST">
    <?php echo $captcha->display(); ?>
    <button type="submit">Submit</button>
</form>

<?php echo $captcha->renderJs(); ?>
