V1 reCAPTCHA

add_filter( 'gform_recaptcha_init_script', 'custom_translation', 10, 3 );
function custom_translation( $script, $form_id, $field ) {
$script = 'RecaptchaOptions.custom_translations = {
instructions_visual : "Scrivi le due parole:",
instructions_audio : "Trascrivi ciu00f2 che senti:",
play_again : "Riascolta la traccia audio",
cant_hear_this : "Scarica la traccia in formato MP3",
visual_challenge : "Modalitu00e0 visiva",
audio_challenge : "Modalitu00e0 auditiva",
refresh_btn : "Chiedi due nuove parole",
help_btn : "Aiuto",
incorrect_try_again : "Scorretto. Riprova."
};RecaptchaOptions.theme = "white"';
return $script;
}

V2 reCAPTCHA

This version of reCAPTCHA is planned to be released with Gravity Forms 2.0 and new reCAPTCHA fields added will use this version. There are only a few customizations that may be done in this version. Please see https://developers.google.com/recaptcha/docs/display for more details.

The example below changes the theme (dark vs. light default) and the type (audio vs. image default).

add_filter( 'gform_recaptcha_init_script','custom_translation', 10, 3 );
function custom_translation( $script, $form_id, $field ) {
$script = 'RecaptchaOptions.theme = "dark";RecaptchaOptions.type = "audio"';
return $script;
}

Placement

This code should be placed in the functions.php file of your active theme.
