Parameterized query binding in ON clause for a LEFT JOIN in Laravel Eloquent / Query Builder

Question

Let\'s say I want to show a full list of awards with type=\"color\":

Awards        Type     2013 Winner
======        ====     ===========
Blue Award    colo         


        

Answer 1

Currently you can use $join->where:

$year = '2013';

$awards = DB::table('awards')
         ->leftJoin('winners', 
               function($join) use ($year)
               {
                    $join
                        ->on('awards.id','=','winners.award_id')
                        // "where" instead of "on":
                        ->where('winners.year', '=', $year);
               }
         ->where('awards.type','color')
         ->get();
