|-------------------------------------------------------------------------------------------------------------------------------------------|

Current Code I am using:

$movie_list = DB::table('movies')
            ->select('movies.*', 'movie_directors.*', 'movie_actors.*', 'movie_genres.*', 'movie_links.*', 'movie_types.*')
            ->join('movie_directors','movies.id', '=','movie_directors.movie_id')
            ->join('movie_actors', 'movies.id', '=', 'movie_actors.movie_id')
            ->where('movies.status',1)
            ->paginate(50)
            ;

Look at the table 'I want' at the bottom of the code. This is what I want. Please don't attach the link below as proof of already answered. It doesn't match with my requirement

Answer 1

In order to achieve this you need to group results by movies.id and use group_concat to extract results comma concatenated. Your code should look something like this:

$movie_list = DB::table('movies')
    ->select(
        'movies.*', 
        DB::raw('group_concat(movie_directors.dir_name) as directors'),
        DB::raw('group_concat(movie_actors.act_name) as actors')
    )
    ->join('movie_directors','movies.id', '=','movie_directors.movie_id')
    ->join('movie_actors', 'movies.id', '=', 'movie_actors.movie_id')
    ->where('movies.status',1)
    ->groupBy('movies.id')
    ->paginate(50)
    ;
