Why is foreach not working?

[eluser]vitoco[/eluser]
row_array() returns only 1 row, use result_array() instead

Code:

function get_files()
{
  $userID = $this->session->userdata('id');  
  $query = $this->db->query('SELECT * FROM upload WHERE userID = '.$userID);
  $num_row = $query->num_rows();
  return $query->result_array();

}
