Laravel ReCaptcha

Easily integrate Google's reCAPTCHA into your Laravel 5+ project.

Installation

composer require nissicreative/laravel-recaptcha

Setup

Add the service provider to the providers array in app/config/app.php.

Nissi\ReCaptcha\ReCaptchaServiceProvider::class,

Configuration

Visit https://google.com/recaptcha and register a new site. You will be assigned a Site Key and a Secret Key.

Add these reCAPTCHA keys to your .env file:

RECAPTCHA_KEY=my-site-key
RECAPTCHA_SECRET=my-secret-key

This is the default config file:

<?php

return [
    'key'           => env('RECAPTCHA_KEY'),
    'secret'        => env('RECAPTCHA_SECRET'),
    'script_url'    => 'https://www.google.com/recaptcha/api.js',
    'verify_url'    => 'https://www.google.com/recaptcha/api/siteverify',
    'error_message' => 'reCAPTCHA validation failed. Please try again.',
    'log_responses' => false,
];

If you would like to modify the config file and/or views, you may run:

php artisan vendor:publish

Usage: The Form Page

In your page's <head> section, add this line to include the remote Google JavaScript file:

@include('recaptcha::script')

Then inside your form, insert the widget:

@include('recaptcha::widget')

That's it! You should now see the reCAPTCHA widget when you refresh the page.

Validating the Response

Validation is simple: Just add a recaptcha rule to your validator. For example, in a controller:

$this->validate($request, [
    'g-recaptcha-response' => 'required|recaptcha',
    // Other rules...
]);

The recaptcha rule takes care of sending the input to Google's servers via Guzzle, and returns true upon successful validation.
