Laravel - 编辑表单中的下拉选项

问题描述 投票：0回答：4

我正在 Laravel 中构建一个 CRUD 应用程序。在我的创建表单中，我让用户从下拉列表中选择一个选项，并将值发布到数据库。

我现在正在尝试编辑该表单，但无法使用 for every 循环动态获取该值。但我可以手动。

这是可行的，但它不是动态的

<select class ="form-control" id="type" name="type">
    <option value="">Select</option>
    <option {{ $Advert->type == 'Apartment' ? 'selected':'' }}>Apartment</option>
    <option {{ $Advert->type == 'House' ? 'selected':'' }}>House</option>
    <option {{ $Advert->type == 'Studio' ? 'selected':'' }}>Studio</option>
    <option {{ $Advert->type == 'Flat' ? 'selected':'' }}>Flat</option>
</select>

我正在尝试使用 foreach 循环在编辑中生成值，但出现错误

尝试获取非对象的属性

这是 foreach 的代码

  <select class ="form-control" id="type" name="type">
      @foreach ($Advert as $type)
          <option {{ $type->type == $Advert->type ? 'selected':'' }}>{{$type->type}}</option>
      @endforeach
  </select>

$advert 上的 VARDUMP

我已经尝试过了。这是最好的解决方案。你可以尝试并享受

假设您要编辑此 

$Advert
对象，那么您必须将此对象以及从数据库获取的每个可用选项一起传递到视图。例如

在您的控制器中：

$Advert = Advert::find($id)
$advert_types = // all the types that you'll get from your database
// maybe something like this
// $advert_types = DB::table('types')->get();
return view('yourview', compact('$Advert', 'advert_types'));

在你看来，你想这样写：

<select class ="form-control" id="type" name="type">
  @foreach ($advert_types as $type)
    <option {{ $type->type == $Advert->type ? 'selected':'' }}>{{$type->type}}</option>
  @endforeach
</select>

然后你就可以完成你的代码了。你只是不能在单个对象（$Advert）中执行 foreach，这就是你收到错误的原因

在您的控制器中：

$advert = Advert::find($id)
$advert_types = Advert::pluck('name', 'id');
return view('yourview', compact('$advert', 'advert_types'));

您的看法：

<select class ="form-control" id="type" name="type">
@foreach ($advert_types as $key => $value)
<option disable="true" value="{{ $key }}" {{ ($key == $advert) ? 'selected' : '' }}>{{$value}}
</option>
@endforeach
</select>
