ReCaptchaV2 integrates Version 2 of Google's ReCaptcha service into MODX as a FormIt hook.

It can also be used with the Login Extra as a preHook, as of version 1.0.0

Version 2+ updates the base Google Recaptcha class to the latest 1.1.2, including autoloading and cURL support. https://github.com/google/recaptcha

You must generate API keys for your domain here: https://www.google.com/recaptcha/admin and enter them into the System Settings before you can use ReCaptchaV2.

###USAGE EXAMPLE:

[[!FormIt?
   &hooks=`recaptchav2,email`
   ...
]]

OR

[[!Login? &preHooks=`recaptchav2`]]

You will also need to call the accompanying form element renderer snippet somewhere in your html form, for example:

<div class="form-item">
    [[!recaptchav2_render]]
    [[!+fi.error.recaptchav2_error]]
</div>

As of 2.3+, you can use the "Invisible Recaptcha" implementation:

<form id="login-form">
[[!recaptchav2_render?
    &tpl=`recaptchav2_invisible_html`
    &form_id=`login-form`
]]
</form>

In this usage, the recaptchav2_invisible_html renders a button with the necessary data attributes to trigger Recaptcha.

The render snippet may or may not be usable as a preHook for FormIt at this time.
