CaptchaFox Extension for Typo3 CMS

You can protect the forms of your Typo3 website using the CaptchaFox Extension.

Configuration

The extension can be configured through the Extension Manager. Important options defined in ext_conf_template.txt include your site key, secret key and language:

site_key = <YOUR_SITE_KEY>
secret_key = <YOUR_SECRET_KEY>
lang = en

Additional options like robotMode and enforceCaptcha control whether the CAPTCHA should be shown during automated testing or development environments.

Usage

After installation you can add the “CaptchaFox” element to a form using the form editor. Internally the partial Resources/Private/Partials/CaptchaFox.html renders the widget and inserts the required scripts:

<div class="captchafox"
     data-sitekey="{configuration.site_key}"
     data-mode="{element.renderingOptions.displayMode}"
     data-lang="{configuration.lang}"
     data-callback="cfVerifyAndSubmit"></div>

Validation is handled by the service in Classes/Services/CaptchaService.php, which sends the user response to the configured verification server.
