用于选择下拉列表的Laravel模型绑定 [英] Laravel model binding for select dropdown

问题描述

我希望在编辑表单中选择选择下拉列表值.

I want the select dropdown value to be selected in my edit form.

在我的控制器中

public function edit($id)
{
    $vedit = DB::table('vehicles')->where('id', $id)->first();
    $cartype= DB::table('car_category')->pluck('cartype'); 
    return view('vehicles.edit', compact('vedit','cartype'));
}

可见

{{ Form::label('Vehicle Type', 'Vehicle Type') }}
<select name="vehicle_type" class="form-control">
  @foreach($cartype as $cartypes)   
  <option value="{{ $cartypes}}">{{ $cartypes}}</option>
  @endforeach
</select>

我该如何实现?

推荐答案

如果是这样选择的属性，则可以添加selected属性:

You can add selected attribute if it's the choosen one like this :

{{ Form::label('Vehicle Type', 'Vehicle Type') }}
<select name="vehicle_type" class="form-control">
    @foreach($cartype as $cartypes) 
        <option value="{{ $cartypes}}" {{ $cartypes == $vedit->vehicle_type ? 'selected' : ''}}>{{ $cartypes}}</option>
    @endforeach
</select>
