README

CaptchaFox offers CAPTCHA protection for TYPO3 forms. This extension integrates the CaptchaFox service into the TYPO3 form framework. After installation a new form element and validator become available inside the form editor, allowing editors to easily protect forms against bots.

Compatibility

Extension version	Supported TYPO3 versions
10.x	TYPO3 v10 and v11
12.x	TYPO3 v12 and v13

Installation

Install via Composer and choose the appropriate version for your TYPO3 installation:

composer require captchafox/captchafox-typo3:^12   # TYPO3 12 or 13
# or
composer require captchafox/captchafox-typo3:^10   # TYPO3 10 or 11

Activate the extension in the Extension Manager or via the TYPO3 CLI.

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 = sk_11111111000000001111111100000000
secret_key = ok_11111111000000001111111100000000
lang = de

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.
