}

This what i have in my controller:

public function updateValues(){
    $this->load->model('get_db');
    $newRow = array(
        array(
            'id' => '3',
            'firstname' => 'Rapphie'
        ),
        array(
            'id' => '2',
            'firstname' => 'Charmie'
        )
    );
