Creating a CAPTCHA verification system in Laravel can help protect your website or application from automated bots and spam. You can use the "laravel-captcha" package to easily integrate CAPTCHA into your Laravel project. Here's a step-by-step guide on how to set up CAPTCHA verification in Laravel using the "laravel-captcha" package:

1. Install the "laravel-captcha" Package:
   Use Composer to install the "laravel-captcha" package.
   composer require mews/captcha

2. Service Provider Configuration:
   After installing the package, add the service provider to your config/app.php file in the providers array:
   'providers' => [ // ... Mews\Captcha\CaptchaServiceProvider::class, ],

3. Publish Configuration and Assets:
   Publish the package's configuration file and assets (fonts and images) to your Laravel project:
   php artisan vendor:publish --tag=captcha

4. Generate CAPTCHA Image:
   In your controller or route handler, generate a CAPTCHA image and display it in a view. Here's an example route handler:
   use Mews\Captcha\Facades\Captcha;
public function showCaptcha() { $captcha = Captcha::create(); return view('captcha', compact('captcha')); }

5. Display CAPTCHA Image in a View:
   Create a view (e.g., captcha.blade.php) to display the CAPTCHA image along with an input field for users to enter the CAPTCHA code.
   <img src="{{ $captcha['image'] }}" alt="CAPTCHA">
<input type="text" name="captcha">

6. Validate CAPTCHA:
   In your form processing logic, validate the CAPTCHA code provided by the user. You can use Laravel's built-in validation to do this:
   use Illuminate\Http\Request;
   `public function processForm(Request $request)
   {
   $request->validate([
   'captcha' => 'required|captcha',
   // Add other validation rules here.
   ]);

   // If the CAPTCHA is valid, continue processing the form.
   }`
   The 'captcha' validation rule is provided by the "laravel-captcha" package.

7. Customize CAPTCHA Settings:
   You can customize the CAPTCHA appearance and behavior by editing the configuration file located at config/captcha.php. For example, you can change font size, image size, and more.

8. Testing:
   Test your CAPTCHA system by loading the CAPTCHA image, submitting the form, and verifying that the CAPTCHA code is validated correctly.

use "reCaptcha" by Google
create an account by visiting the reCaptcha by google website
generate API keys

install recaptcha package on your laravel app
composer require anhskohbo/no-captcha

configure laravel to use the package
'providers' => [ // ... Anhskohbo\NoCaptcha\NoCaptchaServiceProvider::class, ],

also don't forget to add the alias
'aliases' => [ // ... 'NoCaptcha' => Anhskohbo\NoCaptcha\Facades\NoCaptcha::class, ],

add the configuration for recaptcha into your .env file
NOCAPTCHA_SECRET=your-secret-key
NOCAPTCHA_SITEKEY=your-site-key

use captcha on your view
`

@csrf Name:

@captcha

<button type="submit">Submit</button>

` handle the captcha verification at your controller ` use Illuminate\Http\Request; use Illuminate\Support\Facades\Validator; use Anhskohbo\NoCaptcha\NoCaptcha;

public function submitForm(Request $request, NoCaptcha $noCaptcha)
{
// Validate the CAPTCHA
$validator = Validator::make($request->all(), [
'name' => 'required',
'g-recaptcha-response' => 'required|captcha'
]);

if ($validator->fails()) {
    // CAPTCHA validation failed
    return back()->withErrors($validator)->withInput();
}

// CAPTCHA validation passed, continue processing the form
// ...

return redirect()->to('/success-page');

}
you can also use it like this

` ` use Illuminate\Http\Request; use Illuminate\Support\Facades\Validator;

public function store(Request $request)
{
// Validate the reCAPTCHA response
$validator = Validator::make($request->all(), [
'g-recaptcha-response' => 'required|captcha',
]);

if ($validator->fails()) {
    // CAPTCHA validation failed, return an error response or redirect back with an error message.
    return back()->withErrors($validator)->withInput();
}

// CAPTCHA validation succeeded, continue with your form processing logic.
// ...

}
`
