Gravity Forms Update post meta from template [closed]

Here’s the repair, for good measure and anyone curious:

add_action("gform_after_submission_5", "books_promoter", 10, 4);
function books_promoter($entry, $form) {
        global $post;
        global $wp_query;

        $post_id = get_the_ID(); // $entry['post_id'];

        $post_data['status'] = get_post_meta($post_id,'status', true);
        $post_data['promoter'] = get_post_meta($post_id,'promoter', true);

        $status = $entry['5'];
        $promoter = $entry['6'];

        update_post_meta($post_id, 'books_status', $status );
        update_post_meta($post_id, 'books_promoter', $promoter );
}
