Step 4 – Create Model & Migration File For Contact Us Form

In step 4, create model and migration file for contact us form by using the following command:

php artisan make:model ContactUs -m

The above command will create two files into your laravel 8 google v2 recaptcha validation application, which is located inside the following locations:

  • LaravelGoogleV2/app/Models/ContactUs.php
  • LaravelGoogleV2/database/migrations/2020_09_09_025857_create_contact_us_table.php

So, find create_contact_us_table.php file inside LaravelGoogleV2/database/migrations/ directory. Then open this file and add the following code into function up() on this file:

    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();
        });
    }

Now, open again your terminal and type the following command on cmd to create tables into your selected database:

php artisan migrate

Step 5 – Create Routes

In step 5, open your web.php file, which is located inside routes directory. Then add the following routes into web.php file:

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\GoogleV2Controller;


/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('google-v2-contact-us', [GoogleV2Controller::class, 'index']);
Route::post('validate-store', [GoogleV2Controller::class, 'store']);

Step 6 – Creating Controller

In step 6, create form controller by using the following command:

php artisan make:controller GoogleV2Controller

The above command will create GoogleV2Controller.php file, which is located inside LaravelGoogleV2/app/Http/Controllers/ directory.

The following laravel validation rules will validate google recaptcha form data before save into database in laravel:

        $validatedData = $request->validate([
	        'name' => 'required',
	        'email' => 'required',
	        'subject' => 'required',
	        'message' => 'required',
	        'g-recaptcha-response' => 'required|captcha',
        ]);

So open GoogleV2Controller.php file and add the following code into it:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\ContactUs;


class GoogleV2Controller extends Controller
{
    public function index()
    {
        return view('google-v2-recaptcha');
    }

    public function store(Request $request)
    {
        
        $validatedData = $request->validate([
            'name' => 'required',
            'email' => 'required',
            'subject' => 'required',
            'message' => 'required',
            'g-recaptcha-response' => 'required|captcha',
        ]);


        $save = new ContactUs;

        $save->name = $request->name;
        $save->email = $request->email;
        $save->subject = $request->subject;
        $save->message = $request->message;

        $save->save();

        return redirect('google-v2-contact-us')->with('status', 'Google V2 Recaptcha has been validated form');

    }
}

Step 7 – Create Blade File For Contact Us Form

In step 7, create new blade view file that named google-v2-recaptcha.blade.php inside resources/views directory for display contact us form with google v2 recaptcha validation in laravel.

The following code display error message in laravel forms. So do not forget to add the following code along laravel forms fields:

          @error('title')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror

One more thing for use google v2 recaptcha with laravel forms, you need to add the following code on laravel form:

      <div class="form-group">
        <label for="captcha">Captcha</label>
          {!! NoCaptcha::renderJs() !!}
          {!! NoCaptcha::display() !!}
          @error('g-recaptcha-response')
              <div class="alert alert-danger mt-1 mb-1">{{ $message }}</div>
          @enderror
      </div>

Don’t worry i have already added the validation error message display code along with each form fields and google v2 recaptcha validation code.

So, you can add the following php and html form code into google-v2-recaptcha.blade.php:
