Answer 1

Laravel 的辅助函数 groupBy() 会帮你解决这个问题。数据分组示例:

$cars = Car::where('status', 1)->get();
    
$carModels = $cars->groupBy('model');

Blade 示例:

<select name="car_id">
    @foreach($carModels as $model => $cars)
    
      <optgroup label="{{ $model }}">
        @foreach($cars as $car)
          <option value="{{ $car->id }}">{{ $car->name }}</option>
        @endforeach
      </optgroup>
    
    @endforeach
</select>
