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;
}
