即使文件在 fileInput 字段中上传，FileInput 字段也是必需的 - Yii2

Question

我有 2 个文件输入字段，设置为必填字段。即使浏览文件，这 2 个字段也会显示错误消息。

查看

<?php $form = ActiveForm::begin([ 'enableAjaxValidation' => true, 'enableClientValidation' => false, 'options'=>['enctype'=>'multipart/form-data']]); ?>
<div class="div_salary_deposited">
    <div class="row">
        <div class="col-lg-4 col-md-4 col-sm-4">
            <div class="form-group">
                <label class="control-label">Scan copy of Payslip: <span class="required">*</span></label>
                <?= $form->field($modelPlacementTrackingSalaryInformation, 'scan_copy_of_payslip')->label(false)->fileInput() ?>
            </div>
        </div>
        <div class="col-lg-4 col-md-4 col-sm-4">
            <div class="form-group">
                <label class="control-label">Salary Payment Proof: <span class="required">*</span></label>
                <?= $form->field($modelPlacementTrackingSalaryInformation, 'salary_payment_proof')->label(false)->fileInput() ?>
            </div>
        </div>
    </div>
</div>
<div class="form-group">
    <ul class="list-unstyled list-inline">
        <li>
            <button class="btn btn-info" type="submit">Continue</button>
        </li>
    </ul>
</div>
<div class="clearfix"></div>
<?php ActiveForm::end(); ?>

控制器

/* salary-information */
public function actionSalaryInformation(){
    
    $modelPlacementTrackingSalaryInformation = $this->placementTrackingRepository->getPlacementTrackingSalaryInformationModel();
    $modelPlacementTrackingSalaryInformation->placement_tracking_id = $placement_tracking_id;
    
    if(($postData = Yii::$app->request->post()) && !empty($postData) && $modelPlacementTrackingSalaryInformation->load($postData)){
        
        if(Yii::$app->request->isAjax){
            Yii::$app->response->format = Response::FORMAT_JSON;
            return ActiveForm::validate($modelPlacementTrackingSalaryInformation);
        }
    }
    
    return $this->render('salary_information',[
        'modelPlacementTrackingSalaryInformation' => $modelPlacementTrackingSalaryInformation,
    ]);
}

你可以这样尝试吗？

['salary_payment_proof', 'required','when' => function ($model) {
                        return $model->salary_deposited  == '1';
        }, 'whenClient' => "function (attribute, value) {
            return $('your radio button id').val() == '1';
        }"],
