Description

Allows a Captcha using Google's reCAPTCHAv2 API to be added to a form to protect it from being spammed by bots.

Add the following configuration to a file called cfg/cfg.d/recaptcha.pl in your archive, if it does not already exist.

$c->{recaptcha}->{private_key} = "CHANGEME";
$c->{recaptcha}->{public_key} = "CHANGEME";

As this field uses the Google "reCAPTCHAv2" service and renders a Captcha, (a test that humans can easily pass, but robots shouldn't be able to), you will need to use a Google account to generate a private and public key (also known by Google as a secret key and site key respectively) for the above configuration. This can be done via Google's Site Registration Tool. By sure to use version 2 (ReCAPTCHAv2) when registering.

If you are setting up a Recaptcha field for protecting request copy forms, you will need to add the following configuration to a file in your archive's cfg/cfg.d/ directory.

$c->add_dataset_field( "request", {
  name => "captcha",
  replace_core => 1,
  type => "recaptcha",
});
