查看时不显示文件路径，可有解？ [ 2.0 版本 ]

FileInput

use kartik\widgets\FileInput;

// Usage with ActiveForm and model
echo $form->field($model, 'avatar')->widget(FileInput::classname(), [
    'options' => ['accept' => 'image/*'],
]);

// With model & without ActiveForm
echo '<label class="control-label">Add Attachments</label>';
echo FileInput::widget([
    'model' => $model,
    'attribute' => 'attachment_1',
    'options' => ['multiple' => true]
]);

这两种方法都不行
