Use the Add/Update API

Hi,
I’m trying to use php to programmatically add two loops to a page. The loop consists of a file upload and a text input. I found the below in the documentation.

$field_data = array(
    'text_field' => 'Value',
    'loop_field' => array(
        array(
            'loop_text' => 'Value',
            'loop_date' => '2013-01-01 10:30:00',
        ),
        array(
            'loop_text' => 'Value',
            'loop_date' => '2013-01-02 12:45:00',
        ),
    ),
);
$post_data = array('ID' => 678); // the ID is required
CFS()->save($field_data, $post_data);

My question is, how do I add multiple loops for a post? I tried to add one and was able to do it, but I can’t seem to do two loops. Any help would be appreciated.
