如何在 kartik 上传小部件中更新多个图像？
How to update multiple images in kartik Upload widget?
这里我只能在更新模型时预览图像。我想正确加载图像，以便用户可以再删除一个文件，更新将相应地工作这是我的控制器
public function actionUpdate($id)

$model = $this->findModel($id);
$session_data = \common\models\Customer::find()->where(['user_id' => $model->customer_user_id])->one();
$towing = \common\models\TowingRequest::find()->where(['id' => $model->towing_request_id])->one();

$images = \common\models\Images::find()->where(['=', 'vehicle_id', $model->id])->one();
if (!$images) {
$images = new \common\models\Images();
}
if ($images_old) {
foreach ($images_old as $image) {
$baseurl = \Yii::$app->request->BaseUrl;
$image_url = $baseurl . '../backend/uploads/' . $image->thumbnail;
$all_images[] = Html::img("$image_url", ['class' => 'file-preview-image']);
}
} else {
$all_images = '';
}

$features = \common\models\Features::find()->all();
// $vf = Yii::$app->db->createCommand('SELECT * FROM features f left join vehicle_features vf on vf.features_id=f.id;')->queryAll();
$condition = \common\models\Condition::find()->all();
if ($model->load(Yii::$app->request->post()) && $towing->load(Yii::$app->request->post()) && $vehiclefeatures->load(Yii::$app->request->post()) && $vehiclecondition->load(Yii::$app->request->post()) && $images->load(Yii::$app->request->post())) {
$towing->save();
if (!$model->save()) {
$result = [];
// The code below comes from ActiveForm::validate(). We do not need to validate the model
// again, as it was already validated by save(). Just collect the messages.
foreach ($model->getErrors() as $attribute => $errors) {
$result[Html::getInputId($model, $attribute)] = $errors;
}
return $this->asJson(['validation' => $result]);
// Yii::$app->response->statusCode = 422;
}
//delet vehicle features and add new features
$command = Yii::$app->db->createCommand()
->delete('vehicle_features', 'vehicle_id = ' . $model->id)
->execute();
if ($vehiclefeatures->value) {
$vehicle_feature = \common\models\VehicleFeatures::inert_vehicle_feature($model, $vehiclefeatures->value);
}
//delete vehicle condition and add new features
$command = Yii::$app->db->createCommand()
->delete('vehicle_condition', 'vehicle_id = ' . $model->id)
->execute();
if ($vehiclecondition->value) {
$vehicle_condition = \common\models\VehicleCondition::inert_vehicle_condition($model, $vehiclecondition->value);
}
$photo = UploadedFile::getInstances($images, 'name');
if ($photo) {
$command = Yii::$app->db->createCommand()
->delete('images', 'vehicle_id = ' . $model->id)
->execute();
$save_images = \common\models\Images::save_container_images($model->id, $photo);
}
return $this->redirect(['view', 'id' => $model->id]);
}
return $this->render('update', [

}
这是我的表格，我在更新图像时遇到了问题。我知道这里我只是通过将图像添加到控制器中的 $all_images[] 和表单中的 initialPreview => $all_images 来预览图像，以便在上传时显示它。现在我想要的是正确加载图像，这样我就可以删除任何图像并可以添加更多图像。我只想知道如何在更新时在上传小部件中正确加载所有图像在更新时正确上传后我可以在控制器上处理它我将删除并取消链接所有图像并上传更新文件
