F1, F1, F1 please! Routing / remapping

You can define a catch-all route:

Code:

$route['(:any)'] = 'home/index/$1';

Then do some pseudo-routing in the controller method.

Code:

public function index($slug) {
  $query = $this->db->where('slug', $slug)->get('table_name');
  if($query && $query->num_rows() == 1) {
    $row = $query->row();

    do_some_function($row->id);
  } else {
    show_404();
  }
}
