README

This package adds a validation rule and controller trait for easier integration with Google Recaptcha

Installation

Install this package through Composer.

composer require origami/captcha

Requirements

This package is designed to work with Laravel >= 10 currently. If you require 5.8 support, use version 1. If you require 6-7 support use version 2.

Setup

1. Signup for a Google Recaptcha account at https://www.google.com/recaptcha/admin

2. You should add a recatpcha section to your config/services.php file:

    
    'recaptcha' => [
        'key' => env('RECAPTCHA_KEY'),
        'secret' => env('RECAPTCHA_SECRET'),
    ],

1. Update your .env file with the key and secret:

RECAPTCHA_KEY=
RECAPTCHA_SECRET=

1. Add a language line to your validation file(s), e.g. resources/lang/en/validation.php

    'recaptcha' => 'The reCAPTCHA check was invalid',

Usage

Validator

$validator = Validator::make($request->all(), [
    'recaptcha' => [new Origami\Captcha\Rules\Recaptcha],
]);

Controller Validation

(Assuming your Controller has the ValidatesRequests trait)

class Contact extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'recatpcha' => [new Origami\Captcha\Rules\Recaptcha]
        ]);
    }
}

Changing Google secret

If you have multiple Recaptcha secrets (e.g. for different versions), you can customise in the rule params. Otherwise it will default to config('services.recaptcha.secret')

class Contact extends Controller
{
    public function store(Request $request)
    {
        $this->validate($request, [
            'recatpcha' => [new Origami\Captcha\Rules\Recaptcha(secret: '123')]
        ]);
    }
}

Controller with ValidatesCaptcha Trait

use Origami\Captcha\ValidatesCaptcha;

class Contact extends Controller
{
    use ValidatesCaptcha;

    public function store(Request $request)
    {
        $this->validateRecaptcha($request);

        // The above will throw a ValidationException when the recaptcha fails.
    }

}

Blade Helpers

This packages registers two Blade helpers:

@recaptchaField is the equivalent of:

<div class="g-recaptcha" data-sitekey="{{ config('services.recaptcha.key') }}"></div>

@recaptchaScript is the equivalent of:

<script src="https://www.google.com/recaptcha/api.js"></script>

Upgrading

From v2 to v3

Version 3 was created to add Laravel 11.x support and drop support for Laravel versions before 10.x. This is a breaking change as the package now relies on Rule Objects.

// Before
$validator = Validator::make($request->all(), [
    'recaptcha' => 'recaptcha',
]);

// After
$validator = Validator::make($request->all(), [
    'recaptcha' => [new Origami\Captcha\Rules\Recaptcha],
]);

The ValidatesCaptcha trait validateReCaptcha method has been renamed validateRecaptcha
