Laravel database insert query

Question

I\'m trying to do simple insertion in database and im getting the following error

call_user_func_array() expects parameter 1 to be a valid callback, n

Answer 1

DB::table('users')->insert(
     array(
            'id'     =>   '1', 
            'name'   =>   'Dayle'
     )
);

or

$values = array('id' => 1,'name' => 'Dayle');
DB::table('users')->insert($values);

But why are you inserting an ID? Should this not be an auto incremented value?
