我想生成一個顯示年份的下拉列表，到目前為止，這就是我所做的。我在下面的控制器中創建了一個方法。namespace App;use Illuminate\Database\Eloquent\Model;use Illuminate\Support\Carbon;use Illuminate\Support\Facades\Log;class RUMSModel extends Model{    protected $primaryKey = 'id';    protected $fillable = [];    protected $dateFields = [];    protected $dropdownFields = [];    public $module_dir = '';    public $module = '';    public $importFields = [];    public static $months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];    public function selectYear($name, $startYear, $endYear, $selected = null, $options = array())    {        $years = range($startYear, $endYear);        $years = array_combine($years, $years); // [2013 => 2013]        return $this->select($name, $years, $selected, $options);    }?>使用它在 Blade 模板中顯示：<div class="col-lg-6">  <div class="form-group">     <label for="validation-latest_estimate_year"><b>Latest Estimate Year:</b></label>      <select id="validation-latest_estimate_year" class="form-control" name="latest_estimate_year">      <option value="">-Select Year-</option>         @foreach($model->selectYear('year') as $year)           <option value="{{$year}}" {{$year == $model->latest_estimate_year ? 'selected': ''}}>{{$year}}</option>         @endforeach      </select>   </div></div>但是，下拉列表不顯示年份。我試圖找出原因，但我沒有想法。專家的任何指導都會有所幫助。
