Redeem controller data in multiple views

I'm developing a CodeIgniter site in which all pages must have a dynamic footer with data coming from the database.

I loaded the view footer (I created a controller footer ) in the initial controller that loads a default which goes on all pages) and the contents of the initial view and worked, but the other pages do not appear.

I would like suggestions, if at all, on how to do this, how to pass data coming from a controller to various views .

Initial controller index function.

    public function index()
{

    $sql1['where']          =   array(
        'status'    =>  1,  
        "arquivo != " => "''");
    //$sql1['where']            =   array('status'  =>  1,      'destaque'  =>  1,  "arquivo != " => "''", 'data_pub <= ' => "'".date("Y-m-d H:i:s")."'");
