GDPR data privacy checkbox for product reviews

Hi flipstar99!

Yes, please add this code to the child theme functions.php file:

add_action( 'comment_form', 'av_privacy_comment_checkbox_woo', 5 );
function av_privacy_comment_checkbox_woo()
{
  if(!is_product()) return;

  remove_action('comment_form', 'show_subscription_checkbox');

  if(is_user_logged_in()) return;

  $content = do_shortcode(avia_get_option('privacy_message'));

  $id = 'comment-form-av-privatepolicy';

  $output = '<p class="form-av-privatepolicy ' . $id . '" style="margin: 10px 0;">
      <input id="' . $id . '" name="' . $id . '" type="checkbox" value="yes">
      <label for="' . $id . '">' . $content . '</label>
      <input type="hidden" name="fake-' . $id . '" value="fake-val">';

  echo $output;
}

add_filter( 'preprocess_comment', 'av_privacy_verify_comment_checkbox_woo' );
function av_privacy_verify_comment_checkbox_woo( $commentdata ) 
{
    if ( ! is_user_logged_in() && isset( $_POST['fake-comment-form-av-privatepolicy'] ) && ! isset( $_POST['comment-form-av-privatepolicy'] ) )
    {
      $error_message = apply_filters( 'avf_privacy_comment_checkbox_error_message', __( 'Error: You must agree to our privacy policy to comment on this site...' , 'avia_framework' ) );
      wp_die( $error_message );
    }

    return $commentdata;
}

Cheers!
