Question

我有三个依赖的下拉列表，如下所示：

我想获取每个下拉列表的ID。最初，导入是隐藏的。然后，当单击最后一个下拉列表（程序）时，将显示要导入的表单。

从属下拉列表的ID将用于

            $progMaster->state_office_id = $this->valueReplace($line['A'], Programme::getDepartmentStateOffice()); 
            $progMaster->study_centre_id = $this->valueReplace($line['B'], Programme::getDepartmentStudyCentre()); 
            $progMaster->programme_id = $this->valueReplace($line['C'], Programme::getDepartmentProgramme());

控制器

    public function actionIndex()
{
    $model = new Department();      
    $model->scenario = 'import-department';
    $importResults = [];

    if ($model->load(Yii::$app->request->post())) {         
        $model->importFile = UploadedFile::getInstance($model, 'importFile');
        if($model->saveImportFile()) {
            $importResults = $this->importDepartmentData($model);
        }           
    }

    return $this->render('index', [
        'model' => $model,
        'importResults' => $importResults,
    ]);
}

public function importDepartmentData($model)
{              
    $dispResults = []; 
    $totalSuccess = 0;

    $objPHPExcel = PHPExcel_IOFactory::load($model->importFilePath.$model->importFile);
    $sheetData = $objPHPExcel->getActiveSheet()->toArray(null, true, true, true);

    unset($sheetData[1]);

    foreach($sheetData as $k => $line){
        if(!array_filter($line))
            continue;

        $line = array_map('trim', $line);
        $line = array_map(function($value) { return empty($value) ? NULL : $value; }, $line);

        $progMaster = new StudyCentre();

        //set learner info attributes

        $progMaster->state_office_id = $this->valueReplace($line['A'], Programme::getDepartmentStateOffice()); 
                    $progMaster->study_centre_id = $this->valueReplace($line['B'], Programme::getDepartmentStudyCentre()); 
                    $progMaster->programme_id = $this->valueReplace($line['C'], Programme::getDepartmentProgramme());                     

        $progMaster->created_by = Yii::$app->getid->getId();
        $progMaster->created_at = new \yii\db\Expression('NOW()');

        if($progMaster->save())
                    {
                        $totalSuccess+=1;
                        $dispResults[] = array_merge($line, ['type' => 'S', 'departmentId' => $progMaster->id, 'message' => 'Success']);
        }
                    else
                    {
                        $dispResults[] = array_merge($line, ['type' => 'E', 'message' => Html::errorSummary($progMaster)]);                         
        }   
    } //end foreach
    return ['dispResults' => $dispResults, 'totalSuccess' => $totalSuccess];
}
