为每个类别创建视图 - laravel

Question

我目前在一个视图中打印所有类别，并用它们标记子类别之间的差异

@foreach($tipos as $tipo)
   <div class="card">
     
  <h4 style="margin-top: 5px;">{{$tipo->tipo }}</h4> 
  </div> 
    @foreach($tipo->categories as $category)
  <div style="margin-top: 20px;" class="col-lg-4 col-sm-6 mb-4">
    <div class="card h-100">
      <a href="{{ route('category-detail',['slug'=>$category->slug]) }}">
        @if(!empty($category->image))
        <img class="card-img-top" src="{{url($category->image)}}" alt="">
        @else
          <img class="card-img-top" src="http://placehold.it/700x400" alt="">
        @endif
      </a>
      <div class="card-body">
        <h4 class="card-title">
          <a href="{{ route('category-detail',['slug'=>$category->slug]) }}">{{$category->name}}</a>
        </h4>
        <p class="card-text">{{$category->descripcion}}</p>
      </div>
    </div>
  </div>
  @endforeach
  @endforeach

我的名字来自：

分类表： 现在我需要为他们每个人创建一个视图，使用 url 输入它，

控制器：

public function list($id){

   $tipos = App\Tipo::findOrFail($id);
   return view('list.tipos', compact('tipos'));
}

路线：

Route::get('/list{id}','HomeController@list')->name('list.categories');

如何打印每个类别的内容？请帮忙

Answer 1

像这样修改您的控制器
注意：将模型名称 (App\Pivote) 和 (App\Category) 更改为您在代码中设置的名称。

public function list($id){

   $tipos = App\Tipo::findOrFail($id);
   $pivot_data = App\Pivote::select('category_id')->where('tipo_id',$id)->get()->toArray();
   $categories = App\Category::whereIn('id',$pivot_data)->get()->toArray();
   return view('list.tipos', compact('tipos','categories'));
}

然后像这样修改你的视图

<div class="card">     
    <h4 style="margin-top: 5px;">{{$tipos->tipo }}</h4> 
</div> 
@foreach($categories as $key => $category)
    <div style="margin-top: 20px;" class="col-lg-4 col-sm-6 mb-4">
        <div class="card h-100">
            <a href="{{ route('category-detail',['slug'=>$category['slug']]) }}">
            @if(!empty($category['image']))
                <img class="card-img-top" src="{{asset($category['image'])}}" alt="">
            @else
                <img class="card-img-top" src="http://placehold.it/700x400" alt="">
            @endif
            </a>
        <div class="card-body">
            <h4 class="card-title">
                <a href="{{ route('category-detail',['slug'=>$category['slug']]) }}">{{$category['name']}}</a>
            </h4>
            <p class="card-text">{{$category['descripcion']}}</p>
        </div>
    </div>
@endforeach
