This is my current Function in my Controller:
这是我在控制器中的当前功能：
public function addProduct()
{
$categories = Category::all();
return view('admin.products.add')->with('categories', $categories);
}
I want to only select the columns "name" and "id" from the Category Model and assign them to the selectbox in my view like this:
我只想从类别模型中选择列“name”和“id”，并将它们分配给我视图中的选择框，如下所示：
<select>
<option value="ID">NAME</option>
</select>

try with pluckmethod from the laravel Collection:
尝试使用plucklaravel 中的方法Collection：
$categories = Category::all()->pluck('name', 'id');
and then in the view:
然后在视图中：
{!! Form::select('name', $categories) !!}

Try this generate all category
试试这个生成所有类别
<select name="category" class="form-control">
@foreach($categories as $category)
<option value="{{ $category->id }}">{{ $category->name }}</option>
@endforeach
</select>
And if you want to set particular category selected then do this
如果您想设置选定的特定类别，请执行此操作
<select name="category" class="form-control">
@foreach($categories as $category)
<option value="{{ $category->id }}" <?php if($hotel->category_id == $category->id) { echo "selected";}?>>{{ $category->name }}</option>
@endforeach
</select>

Lists was deprecated in L5.2 and removed on L5.3
列表在 L5.2 中被弃用并在 L5.3 中被移除
Try this, simple & neat.
试试这个，简单而整洁。
$categories = Category::lists('name', 'id');
{!! Form::select('categories[]', $categories, null, [
'class' => 'form-control', 'multiple'
]) !!}

You can use foreach here
您可以使用 foreach here
In your blade view.
在您的刀片视图中。
<select name = "category[]">
@foreach($categories as $category)
<option value = "{{$category->id}}">{{$category->youValueHere}}></option>
@endforeach
</select>
