Laravel package for Recaptcha V3

The main motivation for this project was the fact that I could not find an existing package for recaptcha v3 that met two conditions:

possible reading of scores for requests (without rejecting if the score is too low)
the recaptcha token should be generated just before sending the request (and not when generating the page), which may result in an expired token.

Installation

To get started, use Composer to add the package to your project's dependencies:

composer require recurloop/laravel-recaptcha:dev-main

Add RECAPTCHA_SITE_KEY and RECAPTCHA_SECRET_KEY to your .env file. (You can get them here)

RECAPTCHA_SITE_KEY=sitekey
RECAPTCHA_SECRET_KEY=secret

Optionally, you can publish the config file:

php artisan vendor:publish --provider="RecurLoop\Recaptcha\Providers\RecaptchaServiceProvider"

Usage

Init Recaptcha

recaptcha v3 should be loaded on every page to track user activity:

<head>
    ...
    {!! Recaptcha::initJs() !!}
</head>

Forms

a recaptcha token should be sent with each form along with the name of the action performed:

<form method="post" action="/contact">
    <button onclick="{!! Recaptcha::onClickSubmitJs('contact') !!}">Send message</button>
</form>

or

<form method="post" action="/contact" onsubmit="{!! Recaptcha::addTokenJs('contact') !!}">
    <button type="submit">Send message</button>
</form>

Request validation

Register the middleware in your Kernel.php file.

protected $routeMiddleware = [
    ...
    'recaptcha' => \App\Http\Middleware\VerifyRecaptchaScore::class,
    ...
];

You can then reject requests if they do not reach the minimum specified in the config.

Route::post('contact', fn() => null)->middleware('recaptcha:contact');

or with given minimum

Route::post('contact', fn() => null)->middleware('recaptcha:contact,0.7');

Check the score

Alternatively, you can check if the score has been reached directly in the code:

use RecurLoop\Recaptcha\Exceptions\InvalidTokenException;
use RecurLoop\Recaptcha\Facades\Recaptcha;

try {
    // Regardless of the action
    Recaptcha::checkScore(request());
    // Including a token (the token will be invalid if the action does not match)
    Recaptcha::checkScore(request(), 'contact');
    // Taking into account the action and the minimum score
    Recaptcha::checkScore(request(), 'contact', 0.75);
} catch (InvalidTokenException $exception) {
    ...
}

Retrieve the score

Alternatively, you can retrieve the score

use RecurLoop\Recaptcha\Exceptions\InvalidTokenException;
use RecurLoop\Recaptcha\Facades\Recaptcha;

try {
    // Regardless of the action
    $score = Recaptcha::retrieveScore(request());
    // Including a token (the token will be invalid if the action does not match)
    $score = Recaptcha::retrieveScore(request(), 'contact');
} catch (InvalidTokenException $exception) {
    ...
}

Hiding the ReCAPTCHA Badge

Add to your CSS file:

.grecaptcha-badge { visibility: hidden !important; }

Localization

By default, the package follows the default application locale, which is defined in config/app.php. If you want to change this behavior, you can specify what locale to use by adding a new environment variable :

RECAPTCHA_LOCALE=en
