TYPO3 Extension to make use of googles nocaptcha. Now supports googles
invisible reCAPTCHA.

To install the extension add “evoweb/recaptcha” to your project
composer.json or download it from the TER
https://typo3.org/extensions/repository/view/recaptcha and activate the
extension in the extension manager.

Integrate invisible recaptcha in tx_form typoscript forms
---------------------------------------------------------

To be able to use the captcha add the static include of this extension
to your template.

After that, add in the typoscript of the form.

::

   lib.contactForm = FORM
   lib.contactForm {
       70 < lib.invisibleRecaptchaIntegration.10

       rules {
           7 < lib.invisibleRecaptchaIntegration.rules.1
       }
   }

Integrate invisible recaptcha in own forms
------------------------------------------

To be able to use the captcha add the static include of this extension
to your template.

Afterwards modify your form output by replacing the submit button with
something like this:

::

   <button 
       data-sitekey="6LfmFxQUAAAAAGiMRvzLHGYQ8KiQiqgBuY5NswDz"
       data-callback="onContactformCaptchaSubmit"
       class="g-recaptcha"
       type="button" name="tx_form_form[tx_form][id-11]"
       value="absenden">
           absenden
   </button>

After that your are ready on the frontend but still need to call the
validation in your php code.

::

   $validCaptcha = true;

   $captcha = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
       \Evoweb\Recaptcha\Services\CaptchaService::class
   );
   $status = $captcha->validateReCaptcha();

   if ($status == false || $status['error'] !== '') {
       $validCaptcha = false;
   }
