*/
public function index() {
// Load all views as normal
$this->load->view('test');

I do not understand the problem.
like in this code:
$this->load->helper(array('dompdf', 'file'));
// page info here, db calls, etc.
$html = $this->load->view('home', $data, true);
pdf_create($html, 'filename')
or
$data = pdf_create($html, '', false);
write_file('name', $data);
how i put after i upload excel file and cover it to pdf?
this function is only for HTML
