CodeIgniter Select Query

Question

I have a simple CodeIgniter Active record query to select an ID:

$q = $this -> db
           -> select(\'id\')
           -> where(\'email\', $email         


        

Answer 1

one short way would be

$id = $this -> db
       -> select('id')
       -> where('email', $email)
       -> limit(1)
       -> get('users')
       -> row()
       ->id;
echo "ID is ".$id;
