![contact form](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/0igml8mev7ub4bb6tww7.jpg) I spent some time digging up the internet on how to send mail in Laravel and integrate reCaptcha to secure. Although the [documentation](https://laravel.com/docs/9.x/mail#main-content) is pretty straightforward, I wanted some samples and a step-by-step guide. So, here I’ll show you how to integrate reCAPTCHA into your Laravel application to enhance the security of your mail forms. **Note:** I’m using Laravel 9 and will be programmatically invoking the challenge when using reCAPTCHA v3. You may automatically bind the challenge to a button. 1. Generating necessary files: the Model, Migration, Controller, and Markdown Mailable 2. Mail setup 3. reCAPTCHA setup 4. Form view file ## 1. Generating necessary files: the Model, Migration, Controller, and Markdown Mailable ``` php artisan make:model ContactMail -mrc ``` ``` php artisan make:mail ContactMail --markdown=emails.contact-mail ``` ## 2. Mail setup Add the mail host, port, address .etc to the .env file. ``` MAIL_MAILER=log MAIL_HOST=mailhog MAIL_PORT=1025 MAIL_USERNAME=null MAIL_PASSWORD=null MAIL_ENCRYPTION= MAIL_FROM_ADDRESS="email@email.com" MAIL_FROM_NAME="${APP_NAME}" ``` **ContactMail.php** Update the constructor. ``` public $data; /** * Create a new message instance. * * @return void */ public function __construct($data) { $this->data = $data; } ``` **contact-mail.blade** ``` email: {{ $data->email }} **{{ $data->subject }}**
{{ $data->message }}
``` **web.php (route)** ``` Route::name('contact.') ->prefix('contact/') ->group(function () { Route::get('', 'ContactMailController@index')->name('index'); Route::post('store', 'ContactMailController@store')->name('store'); }); ``` ## 3. reCAPTCHA setup Register your reCAPTCHA v3 keys on the [reCAPTCHA Admin console](https://www.google.com/recaptcha/admin/create) here. Add it to your .env file. ``` RECAPTCHA_SITE_KEY= RECAPTCHA_SECRET_KEY= ``` **ContactMailController.php** ``` /** * Display a listing of the resource. * * @return \Illuminate\Http\Response */ public function index() { return view('pages.contact.index'); } ``` ``` /** * Store a newly created resource in storage. * * @param \Illuminate\Http\Request $request * @return \Illuminate\Http\Response */ public function store(Request $request) { // form validation $data = $request->all(); $rules = [ 'email' => 'nullable|email', 'subject' => 'required', 'message' => 'required', ]; $validator = Validator::make($data, $rules); // if form validation fails if ($validator->fails()) { return Response::json(array( 'validation' => false, 'message' => $validator->getMessageBag()->toArray() ), 200); // 400 invalid requests } // verify and get validation $response = Http::asForm()->post('https://www.google.com/recaptcha/api/siteverify', [ 'secret' => env('RECAPTCHA_SECRET_KEY'), 'response' => $request->recaptchaToken, ]); $recaptchaResponse = $response->json(); // if captcha valid if ($recaptchaResponse['success'] == true) { ContactMail::create($request->all()); $message = [ 'success' => true, 'message' => 'Thank you for taking the time to report your concerns.', ]; return response()->json($message, 200); } // if captcha invalid elseif ($recaptchaResponse['success'] == false) { $message = [ 'success' => false, 'message' => 'You a robot?', ]; return response()->json($message, 200); } else { $recaptchaFail = 'Something went wrong.'; return response()->json($recaptchaFail, 200); } } ``` You got to import the necessary facades. ## 4. Form view file **contact.blade** ``` ``` ``` ``` Integrating Google reCAPTCHA into your Laravel mail forms is an effective solution for enhancing the security of your web application. This guide provides a step-by-step approach for adding reCAPTCHA, making it easy for developers of all skill levels to send secure emails.
