How to set a default value Dropdown approcach?

Just to correct yours a little bit. form_drop_down() array doesn't start at 1. It's because you pre-format the array within the model, which make them always has key bigger than 0

Code:

// This one
foreach($query->result_array() as $row)
  {
   $data22[$row['id']]=$row['name'];
  }

Actually, it's faster to do like what PhilTem said, since it's 1 less loop.
