Remove 'website' field from comment form

The customized php snippet in your documentation here doesn’t seem to work:

I managed to get it working with the following:

function gd_disable_comment_url($fields){
    if(isset($fields['url']))
       unset($fields['url']);
       return $fields;
}

add_filter('comment_form_default_fields', 'gd_disable_comment_url');
