To add flashdata:

$this->session->set_flashdata('stack', 'overflow');

You can use on view with this code:

$this->session->flashdata('stack');

Be sure your web page shouldn't redirect one more times. If your redirection counts is more than one, you need to use:

$this->session->keep_flashdata('stack');
