when you do the scaffolding for your database, you need to create a class to handle each table.

this can get annoying, long story short. I added session data that updates to whichever table you want to view.

class Admin extends Controller {

  function __construct()
  {
    parent::Controller();
    
    $this->load->helper(array('url'));
    
    $this->is_logged_in();
    
    if ($this->uri->segment(2) == 'scaffolding' && $this->uri->segment(3) != '' && ($this->uri->segment(4) == null))
    {
    
      $tables = $this->db->list_tables();
      foreach ($tables as $table)
      {
        if ($this->uri->segment(3) == $table)
        {
          $sdata = array(
            'table' => $this->uri->segment(3)
          );
          $this->session->set_userdata($sdata);
        }
      }
    }
    if ($this->uri->segment(2) == 'scaffolding')
    {
      $this->load->scaffolding($this->session->userdata('table'));
    }
  }

  function index()
  {
    echo "Logged in as ". $this->session->userdata('username')."
n";
    
    $tables = $this->db->list_tables();
    
    foreach ($tables as $table)
    {
      echo "'.$table.'
';
    }
  }
  
  function is_logged_in()
  {
    
    $is_logged_in = $this->session->userdata('is_logged_in');
    
    if (!isset($is_logged_in) || $is_logged_in != true)
    {
      redirect('login');
      die();
    }
    
    
  }
  
  
}

?>

the code assumes that you have a way of verifying the ability to access, as need at least some security when using scaffolding. That can be hacked out easily though.
