Hello buddies,
How are you guys? Today I am going to show you how to add google Recaptcha to your laravel web application. Let’s look at an example of integrating Recaptcha in laravel application. This article will go over how to implement google Recaptcha in Laravel 8. I’ll teach you how to use Google’s v3 ReCAPTCHA with Laravel 8 forms in this article. This tutorial will show you how to use Recaptcha in laravel.
Create Laravel project
composer create-project --prefer-dist laravel/laravel blogSet Database Configuration properties
Go to the .env file and set your Database name, Database username, and password.
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravelblog
DB_USERNAME=root
DB_PASSWORD=Install Laravel josiasmontag/laravel-recaptchav3
We need josiasmontag/laravel-recaptchav3 package. you can install the google v3 Recaptcha validation package in laravel 8 google v3 Recaptcha validation app. So let’s open the terminal and run the below command:
composer require josiasmontag/laravel-recaptchav3 Github-link: josiasmontag/laravel-recaptchav3
After installing the above package, you can add providers and aliases in the config file. So let’s run the below command to publish the config file:
php artisan vendor:publish --provider="Lunaweb\RecaptchaV3\Providers\RecaptchaV3ServiceProvider"Then add the site key and secret key on the .env file provided by the google Recaptcha website.
NOCAPTCHA_SITEKEY=your_secret_site_key
NOCAPTCHA_SECRET=your_secret_key Create Model and Migration
We are going to create a Google Recaptcha v3 application for the contact-us page in my laravel app. So run the below command:
php artisan make:model ContactUs -mAdd the following code to your database/migrations file
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateContactUsTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('contact_us', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('email');
$table->string('subject');
$table->text('message');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('contact_us');
}
}
Migrate
php artisan migrateNow you can add all table columns in fillable So let’s open the model file and put the below code.
app/Models/ContactUs.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class ContactUs extends Model
{
use HasFactory;
protected $table = 'contact_us';
protected $fillable = ['name', 'email','subject','message'];
}
Create Routes

Go to the .env file and create the following routes respectively
routes/web.php
Route::get('contact-us', [GoogleV3CaptchaController::class, 'index']);
Route::post('validate-g-recaptcha', [GoogleV3CaptchaController::class, 'validateGCaptch']);Create Controller
Now it’s time to create our controller, run the below command:
php artisan make:controller recaptcha\GoogleV3CaptchaControllerapp/Http/Controllers/recaptcha/GoogleV3CaptchaController.php
<?php
namespace App\Http\Controllers\recaptcha;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use App\Models\ContactUs;
use Validator;
use Session;
class GoogleV3CaptchaController extends Controller
{
public function index()
{
return view('contact');
}
public function validateGCaptch(Request $request)
{
$input = $request->all();
$validator = Validator::make($input,[
'name' => 'required',
'email' => 'required',
'subject' => 'required',
'message' => 'required',
'g-recaptcha-response' => 'required',
]);
if ($validator->passes()){
ContactUs::create($input);
return redirect('contact-us')->with('status', 'Google V3 Recaptcha has been validated form');
}
return redirect()->back()->withErrors($validator)->withInput();
}
}
Create Blade File(contact)
We need to add a blade view so first create a new file contact.blade.php file and put the below code:
resources/views/contact.blade.php
<!DOCTYPE html>
<html>
<head>
<title>Google Recaptcha Validation In Laravel 8 Form</title>
<meta name="csrf-token" content="{{ csrf_token() }}">
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
</head>
<body>
<div class="container mt-4">
@if(session('status'))
<div class="alert alert-success">
{{ session('status') }}
</div>
@endif
<div class="card">
<div class="card-header text-center font-weight-bold">

<div class="card-body">

<div class="form-group">

<script src="https://www.google.com/recaptcha/api.js?render={{ config('services.recaptcha.sitekey') }}"></script>

grecaptcha.ready(function() {
grecaptcha.execute('{{ config('services.recaptcha.sitekey') }}', {action: 'contact'}).then(function(token) {
if (token) {
document.getElementById('recaptcha').value = token;
}
});
});
</script>
<!-- <script src="https://www.google.com/recaptcha/api.js?render={{ config('services.recaptcha.sitekey') }}"></script> -->
