Download laravel 6 Setup

First We need to Download fresh laravel 6 setups. Use the below command to download the laravel 6 fresh setup on your system.

composer create-project --prefer-dist laravel/laravel blog

Setup Database Credentials

After successfully download laravel 6 Application, Go to your project .env file and set up database credential and move next step :

  DB_CONNECTION=mysql 
  DB_HOST=127.0.0.1 
  DB_PORT=3306 
  DB_DATABASE=here your database name here
  DB_USERNAME=here database username here
  DB_PASSWORD=here database password here

Install Google Captcha Package

Now We will Install the Google Captcha Package in your laravel 6 application. Use the below command and install this package in your laravel application.

composer require anhskohbo/no-captcha

After successfully Install Google Captcha Packages, open config/app.php file and add service provider and alias.

 
 config/app.php
 
 
 'providers' => [
 
 
 Anhskohbo\NoCaptcha\NoCaptchaServiceProvider::class
 
 
 ],
 
 
 'aliases' => [
 
 
 'NoCaptcha' => Anhskohbo\NoCaptcha\Facades\NoCaptcha::class,
 
 
 ]  

Get Google Captcha Secrets

Now I will create google Recaptcha site_key and secret_key for showing the Recaptcha in laravel application. If you have already site_key and secret_key, so you need to put the .env file. If you don’t know where we will get secret_key and secret_site click below the link and create your own secret credentials. Recaptcha new site registration

When you click this link Recaptcha new site registration you will see the form look like. Here fill all the details and submit the form.

You will submit the above form after that you will see your secret_site and secret_key, Copy your credentials here and put your .env file

After that, we will set the google captcha secret in .env files, let’s open .env file and add this credentials here :

 NOCAPTCHA_SITEKEY=secret_site_key
 NOCAPTCHA_SECRET=secret_key

Create Route

Now We will add two routes in the web.php file as below. The first is showing form and second is store form data into the database.

Open routes/web.php file

 Route::get('captcha-form', '[email protected]');
 Route::post('store-captcha-form', '[email protected]');

Create Controller

We need to create new controller CaptchaController that will manage two methods. lets use this below command and create a Controller.

php artisan make:controller CaptchaController

Now open the controller let’s go to the => app/Http/Controllers/CaptchaController.php. Now create some methods for showing and storing data into a database.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Validator,Redirect,Response;
use App\User;

class CaptchaController extends Controller
{
    public function captchaForm()
    {
       return view('captchaform');
    }  
    public function storeCaptchaForm(Request $request)
    {
        request()->validate([
        'name' => 'required',
        'email' => 'required',
        'mobile_number' => 'required',
        'g-recaptcha-response' => 'required|captcha',
        ]);

        dd('successfully validate');
    }
}

Create Blade View

Next, create a captchaform.blade.php file in resources/views/ folder and copy-paste the following code.

<!doctype html>
<html lang="en">
  <head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
  <meta name="csrf-token" content="{{ csrf_token() }}">
