Integrating Google ReCaptcha in Laravel 5.8

reCAPTCHA is a free service from Google. It’s a CAPTCHA-like system designed to recognize that the user is human and, at the same time, assist in the digitization of books. It helps to protects your website from spam and abuse.

Note :

If you’re running the Laravel Project at your Local Server. It’s also acceptable for testing Google reCAPTCHA.

In this tutorial, You’ll learn to integrate Google reCAPTCHA in your Laravel Project. Follow the step by step guide to create the application.

  1. Create reCAPTCHA for your Domain

First, You need to create reCAPTCHA for your domain by logging into Google reCAPTCHA Admin Console.

  1. Set the Keys in .env file

After creating the account, Obtain the Key and Secret. Add them to the .env file as shown below,


RECAPTCHA_KEY='your recaptcha key' RECAPTCHA_SECRET='your recaptcha secret'
Code language: JavaScript (javascript)

You can name the key and secret as you like. I have named them as RECAPTCHA_KEY, RECAPTCHA_SECRET .It is required later in the validation form.

  1. Create the Form Request Validaiton

Create the Custom Validation Rules using form request validation in by typing the following command,

php artisan make:request ReCaptchaFormRequest
Code language: CSS (css)

The generated class will be stored in in the app/Http/Requests file directory. Open ReCaptchaFormRequest.php from the directory and add the validation rules inside the rules method

<?php namespace App\Http\Requests; use Illuminate\Foundation\Http\FormRequest; class ReCaptchaFormRequest extends FormRequest { public function authorize() { return true; } public function rules() { return [ 'g-recaptcha-response'=>'required|recaptcha' ]; } }
Code language: HTML, XML (xml)
  1. Create the Custom Validation with Guzzle

If you don’t have Guzzle, Install it by typing the command below at your terminal

composer require guzzlehttp/guzzle
Code language: JavaScript (javascript)

After installing Guzzle, Create a directory as Validation, Inside the Validation folder, Create a PHP file as ReCaptcha.php and add the code below,


<?php namespace App\Validation; use GuzzleHttp\Client; class ReCaptcha { public function validate($attribute, $value, $parameters, $validator) { $client = new Client(); $response = $client->post( '', ['form_params' => [ 'secret' => env('RECAPTCHA_SECRET'), 'response' => $value ] ] ); $body = json_decode((string)$response->getBody()); return $body->success; } }
Code language: HTML, XML (xml)

The next step is to register Validation in AppServiceProvider’s Boot method.

public function boot() { Validator::extend('recaptcha','App\\Validation\\ReCaptcha@validate'); }
Code language: CSS (css)
  1. Create the Captcha Controller

Type the following command at your terminal to create CaptchaController.php file in controllers

php artisan make:controller CaptchaController
Code language: CSS (css)

Create two methods as index and captcha in CaptchaController.


<?php namespace App\Http\Controllers; use App\Http\Requests\ReCaptchaFormRequest; use Illuminate\Http\Request; class CaptchaController extends Controller { public function index() { return view('index'); } public function captcha(ReCaptchaFormRequest $reCaptchaFormRequest) { return "Done!"; } }
Code language: HTML, XML (xml)
  1. Create the Routes

In this step, Go to ‘routes->web.php’ file and add the following code.

Route::get('/','CaptchaController@index'); Route::post('/','CaptchaController@captcha');
Code language: PHP (php)
  1. Create the index.php View File

The final step is to create the index.php file in views directory
