You should be able add an alias via a SELECT clause to the columns you want to join up, and then reference that in the LISTS() call.

$list = MyModel::select(
        DB::raw("(first_name +' '+ last_name) AS full_name, id")
    )->lists('full_name', 'id');

I can't remember the order of the key/value for LISTS(), but that should do it.

You should always create your queries on mysql and make sure thy work it should be something like this

CONCAT(first_name, ' ', last_name) AS full_name, id ( note that there's a space between the 2 single quotes), then make it work the laravel way

This does not works (L5.2) in a {!! Form::select !!}}.

While in tinker has the right answare, i obtain an empty list (only "option value=" is set ti ID) in the select control tag:

{!! Form::select('driver_id',  App\Driver::select(DB::raw("CONCAT(first_name,' ', last_name) AS full_name, id"))->pluck('full_name','id'), null, ['class' => 'form-control'])  !!} 

Why ? Thank you.
