Step 4 – Create Model & Migration
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 google v3 recaptcha validation application, which is located inside the following locations:
- LaravelGoogleV3Recaptcha/app/Models/ContactUs.php
- LaravelGoogleV3Recaptcha/database/migrations/create_contact_us_table.php
So, find create_contact_us_table.php file inside LaravelGoogleV3Recaptcha/database/migrations/ directory. Then open create_contact_us.php 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:
use App\Http\Controllers\GoogleV3CaptchaController;
Route::get('google-v3-recaptcha', [GoogleV3CaptchaController::class, 'index']);
Route::post('validate-g-recaptcha', [GoogleV3CaptchaController::class, 'validateGCaptch']);
Step 6 – Create Controller
In step 6, create Google v3 recaptcha controller by using the following command:
php artisan make:controller GoogleV3CaptchaController
The above command will create GoogleV3CaptchaController.php file, which is located inside LaravelGoogleV3Recaptcha/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|recaptchav3:contact-us,0.5'
]);
So open GoogleV3CaptchaController.php file and add the following code into it:
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\ContactUs;
class GoogleV3CaptchaController extends Controller
{
public function index()
{
return view('google-v3-recaptcha');
}
public function validateGCaptch(Request $request)
{
$validatedData = $request->validate([
'name' => 'required',
'email' => 'required',
'subject' => 'required',
'message' => 'required',
'g-recaptcha-response' => 'required|recaptchav3:contact-us,0.5'
]);
$save = new ContactUs;
$save->name = $request->name;
$save->email = $request->email;
$save->subject = $request->subject;
$save->message = $request->message;
$save->save();
return redirect('google-v3-recaptcha')->with('status', 'Google V3 Recaptcha has been validated form');
}
}
Step 7 – Create Blade File
In step 7, create new blade view file that named google-v3-recaptcha.blade.php inside resources/views directory for display contact us form with google v3 recaptcha validation in laravel.
One more thing for use google v3 recaptcha with laravel forms, you need to add the following code on laravel form:
{!! RecaptchaV3::initJs() !!}
{!! RecaptchaV3::field('contact-us') !!}
Don’t worry we have already added the validation error message display code along with each form fields and google v3 recaptcha validation code.
So, you can add the following php and html form code into google-v3-recaptcha.blade.php:
<!DOCTYPE html>
<html>
