目前，当我想在我的帖子中添加标签时，我必须转到我的tags page并创建它们，然后转到我的post create页面并通过多个输入字段将它们添加到我的帖子中，到目前为止，一切正常。
但是如果我想让我的标签系统像WordPress一样工作呢？意思是我写我的标签在我的多个领域在我的post create page，如果该标签已经存在，只是将被添加，如果不是作为新的标签将save in database，并在该职位以及？
Laravel版本：5.5
更新：
PostController注：我的帖子根据我的应用程序要求命名食物（只是不同的命名）
创建方法

public function create()
    {
      $ingredients = Ingredient::all();
      $vaghts = Vaght::all();
      $categories = Category::all();
      $user = Auth::user();
      return view('panel.foods.create', compact('ingredients', 'vaghts', 'user','categories'));
    }

存储方法

public function store(Request $request)
    {

      //Validating title and body field
      $this->validate($request, array(
          'title'=>'required|max:225',
          'slug' =>'required|max:255',
          'user_id' =>'required|numeric',
          'image' =>'sometimes|image',
          'description' => 'required|max:100000',
          'category_id' => 'required|numeric',
          'status' => 'required|numeric',
        ));

      $food = new Food;

      $food->title = $request->input('title');
      $food->slug = $request->input('slug');
      $food->user_id = $request->input('user_id');
      $food->description = $request->input('description');
      $food->category_id = $request->input('category_id');
      $food->status = $request->input('status');


      if ($request->hasFile('image')) {
        $image = $request->file('image');
        $filename = 'food' . '-' . time() . '.' . $image->getClientOriginalExtension();
        $location = public_path('images/');
        $request->file('image')->move($location, $filename);

        $food->image = $filename;
      }

      $food->save();
      $food->vaghts()->sync($request->vaghts, false);
      $food->ingredients()->sync($request->ingredients, false);

      //Display a successful message upon save
      Session::flash('flash_message', 'Food, '. $food->title.' created');
      return redirect()->route('foods.index');
    }

标签方法：注：我有两个不同类型的标签，他们是相同的，所以如果我只能得到一个，我会做下一个自己
