Chained Select with Form Generation Library

The PHP error tell you that you have an non-array type in your foreach() (in your view file). If you're supply foreach argument directly from your database, make sure you had the right output on your model(or place some data validation properly on your view file, before put it on foreach statement)!
This is an example of common pitfall:

Code:

function some_sql()
{
   $query = $this->db->get('foo');
   // This will generates error when the database returned 0 result, if you didnt place some data validation properly on your view file.
   if(count($query->result_array()) > 0)
   {
      return $query->result_array();
   }
}
