Laravel实现ORM带条件搜索分页

$users = DB::table('users')- where('votes', '=', 100)- get();

$users = User::where('votes', '=', 100)- all();

$articles = Article::where('id',' ','10')- where('is_auth','=','1')- where('id','=','14')- paginate(3)

public function index(Request $request)
  {
    //分类表数据
    $sorts = Sortart::all();
    //文章表实例化
    $article = new Article;
    //搜索条件判断
    $where = $article;
    if($request- search_sid){
      $where = $where- where('sort_id','=',$request- search_sid);
    }
    if($request- search_title){
      $where = $where- where('title','like','%'.$request- search_title.'%');
    }
    //分页搜索
    $articles = $where- paginate(3);
    //搜索条件保持
    $articles- sid = $request- search_sid;
    $articles- title = $request- search_title;
    //$articles = Article::where('id',' ','10')- where('is_auth','=','1')- where('id','=','14')- paginate(3);
    //dd($articles);
    return view('admin.articles.index',compact('articles','sorts'));
  }

{!! $articles- appends(['search_sid'= $articles- sid, 'search_title'= $articles- title])- render() !!}
