Dynamic reCAPTCHA Language

The language of the reCAPTCHA is stored as a Ninja Forms setting, which can be dynamically set on page load to accommodate multi-lingual sites or language specific forms.

<?php
/**
* Update the recaptcha_lang setting.
*
* @param string $setting_key
* @param string $new_value
* @param bool $defer_update True will update the value in memeory, but will not update the database.
*/
Ninja_Forms()->update_setting( 'recaptcha_lang', $recaptcha_lang, true );
