access variable from different method within same model class

[eluser]Krzemo[/eluser]

Code:

// this is a model class
class Holiday_model extends Model
{
  var $sql;

  function Holiday_model()
  {
      parent::Model();
      $this->load->database(‘holiday’, TRUE);
  }

  function view_package()
  {
      $this->sql = “select * from package_details”;
      $query = $this->db->query($this->sql);
      return $query->result_array();
  }

  function get_package_details($id)
  {
      $new_sql = $this->sql;//please write here the code

      $row =  $new_sql.” where id = ‘$id’”;
    
      $query = $this->db->query($row);
      return $query->row_array();
  }

}
?>

I'd dont see any point in doing it this way. IMHO it only complicates the code and makes it harder to maintain.
