Question

我是laravel newbie，我正在尝试编写搜索API，示例网址如下。排序＆＃39; +＆＃39;意思是提升和＆＃39; - ＆＃39;意思是下降。查询，类别部分已完成，我得到了所需的结果，但排序部分仍然存在。我不知道如何动态进行多次排序。我可以按顺序给出一系列排序，例如where（）子句[[＆＃39; rating＆＃39;，＆＃39; asc＆＃39;]，[＆＃39;距离＆＃39;，＆＃39;降序＆＃39;]]。我看过很多帖子，人们通过再次调用orderBy（）和agin进行多次排序，但这是静态的，例如orderBy('rating','asc')->orderBy('distance','desc')，我怎么能动态地做到这一点？

？

class SearchController extends Controller
{
    public function index(Request $request){

        $sort = explode(',', $request->sort);

        return DB::table('posts')->join('users', 'users.id', '=', 'posts.user_id')->join('locations', 'locations.id', '=', 'users.location_id')->join('main_categories', 'main_categories.id', '=', 'posts.main_category_id')->select('posts.*', 'users.*', 'locations.address', 'main_categories.name as cat', DB::raw('ROUND((6371 * ACOS(COS(RADIANS(31.430443800000003)) * COS(RADIANS(locations.lattitude)) * COS(RADIANS(locations.longitude) - RADIANS(74.280726)) + SIN(RADIANS(31.430443800000003)) * SIN(RADIANS(locations.lattitude)))),2) AS DISTANCE'))->where([['posts.title','like','%'.$request->q.'%'],['main_categories.name', '=', $request->cat]])->orwhere([['posts.description','like','%'.$request->q.'%'],['main_categories.name', '=', $request->cat]])->orderBy($request->sort,'DESC')->get();
    }
}

Answer 1

$query // your query

foreach($sorts as $sort)
{
  $query->orderBy($sort,'DESC')
}

$sortedQuery = $query->get();
