Question

目前，当我想在帖子中添加标签时，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一切都很好。

但是，如果我想让我的标签系统像WordPress一样工作怎么办？表示我在post create page的多个字段中编写我的代码，如果该代码已经存在则会添加，如果不是，那么新代码将是save in database，也会在该帖子中添加？

Laravel版本：5.5

更新

PostController注意：我的帖子根据我的应用需要命名食物（只是命名不同）

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：注意：我有两种不同类型的标签，它们是相同的，所以如果我只能得到一个，我会自己做下一个标签

创建方法

public function create()
    {
      return view('panel.vaghts.create');
    }

存储方法

public function store(Request $request)
    {
      //Validating title and body field
      $this->validate($request, array(
          'title'=>'required|max:225',
        ));

      $vaght = new Vaght;

      $vaght->title = $request->input('title');

      $vaght->save();


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

您需要的所有东西都是用这个包处理的

它使标记系统成为一块蛋糕！只需按照文档

Answer 2

您可以先尝试搜索哪些标记已存在，哪些标记是新标记，然后创建新标记。之后，附加/同步从用户收到的所有标签。

//get old vaghts title
$existingVaghts = $food->vaghts->pluck('title')->toArray();

//find new vaghts
foreach($request->vaghts as $vaght) {
    if(! ( in_array($vaght, $existingVaghts) ) ) {
        //create a new vaght
        $newVaght = new App\Vaght;
        $newVaght->title = $vaght;
        $newVaght->save();
    }
}

$attachableVaghts = [];

foreach($request->vaghts as $vaght) {
    $attachableVaghts[] = App\Vaght::where('title', $vaght)->pluck('id')->first();
}

$food->vaghts()->sync($attachableVaghts);

我认为应该这样做。希望能帮助到你。请查看以下链接以获取更多https://codeshare.io/5Ppygd
