Laravel-ORM带条件搜索分页

Laravel条件搜索一般使用where方法，如下：

查询构造器：

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

或者ORM:

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

当有多个条件时，可以多次调用where方法：

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

所以，如果需要进行多条件搜索分页，我们可以这么写：

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"));
    }

在页面中，使用url保持分页条件的方法：

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

效果如图：
