{
  redirect('/poll/list');
}

but I need to pass a variable like $error to show the some error indication, but I don’t know how to pass the parameter to redirect method in the URL helper, and idea?

Answer 1

Use session flashdata – this is exactly what it is designed for:

if(!validate)
{
  $this->session->set_flashdata('error', 'your_error');
  redirect('/poll/list');
}

Then inside your poll/list function:

$error_msg = $this->session->flashdata('error');
