EU CAPTCHA for Laravel

Frequently Asked Questions

• How do I add EU CAPTCHA to a Laravel application?

  Require the EU CAPTCHA PHP client via Composer and add your secret key to .env. In your Blade templates, load verify.js and place the EU CAPTCHA widget div with your sitekey inside the form. In your controller or Form Request, read $request->input('eu-captcha-response') and call the client's verify method before processing the submitted data.

• Does EU CAPTCHA work with Laravel's Form Request validation?

  Yes. The cleanest integration in Laravel is adding the CAPTCHA verification inside a custom Form Request class. Override the withValidator method or add a custom rule in the rules array that calls the EU CAPTCHA PHP client. If verification fails, Laravel's validation response automatically returns the user to the form with the appropriate error message.

• Is there an official EU CAPTCHA package for Laravel?

  EU CAPTCHA provides an official PHP client via Composer that works with Laravel. You can bind it in a service provider as a singleton and inject it into your controllers or Form Request classes using Laravel's dependency injection container. This follows standard Laravel patterns and makes the CAPTCHA service available throughout your application.

• How do I verify a CAPTCHA token in a Laravel controller?

  Inject the EU CAPTCHA PHP client into your controller via the constructor or method injection. In your store or update method, call $captcha->verify($request->input('eu-captcha-response')) after retrieving the token from the request. If verification fails, use back()->withErrors(['captcha' => 'Verification failed']) to redirect the user back to the form.

• Can I use EU CAPTCHA with Laravel Livewire?

  Yes. In a Livewire component, include the EU CAPTCHA widget div in your Blade template with the sitekey. When the form is submitted through a Livewire action, read the eu-captcha-response from the request using request()->input('eu-captcha-response') and call the EU CAPTCHA PHP client to verify it before running your component action logic.

• How do I protect Laravel's default authentication forms with EU CAPTCHA?

  Override Laravel's default login and registration controllers or use Laravel Fortify's pipeline to add EU CAPTCHA verification. For Breeze or Jetstream, modify the store method in the auth controllers to include the verification step before the standard authentication logic. Add the widget div to the corresponding Blade views.

• Is EU CAPTCHA GDPR compliant for Laravel applications?

  Yes. EU CAPTCHA is operated by an EU-based company, is hosted entirely in Germany, and does not rely on US cloud providers or infrastructure subject to US surveillance laws. The service processes only the data necessary to provide and verify the CAPTCHA (such as IP address and technical browser or device information) in line with the requirements of the GDPR.
