Description

Allows a Captcha using Google's reCAPTCHAv3 service 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/recaptcha3.pl in your archive, if it does not already exist.

$c->{recaptcha3}->{private_key} = "CHANGEME";
$c->{recaptcha3}->{public_key} = "CHANGEME";
$c->{recaptcha3}->{min_score} = 0.5;

As this field uses the Google's reCAPTCHAv3 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 Score based (v3) option when registering.

If you are setting up a Recaptcha3 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 => "recaptcha3",
});

If you find you are still getting spam from the form to which you have applied a Recaptcha3 field, then try increasing $c->{recaptcha3}->{min_score} to a higher value such as 0.7.
