如何在Yii2的两个不同路径上载两个文件？

Question

public function actionCreate()
{
        $model = new RoomTypes();
        if ($model->load(Yii::$app->request->post())) 
        {
            $imageName_1 = $model->room_type.'_'.'1';
            $model->pic_1 = UploadedFile::getInstance($model, 'pic_1');
            $model->pic_1->saveAs('uploads/room_pics/'.$imageName_1.'.'.$model->pic_1->extension);
            $model->pic_1 = 'uploads/room_pics/'.$imageName_1.'.'.$model->pic_1->extension;

            $imageName_2 = $model->room_type.'_'.'2';
            $model->pic_2 = UploadedFile::getInstance($model, 'pic_2');
            $model->pic_2->saveAs('uploads/room_pics/'.$imageName_2.'.'.$model->pic_2->extension);
            $model->pic_2 = 'uploads/room_pics/pic2/'.$imageName_2.'.'.$model->pic_2->extension;
            $model->save();
            return $this->redirect(['view', 'id' => $model->id]);
        } else 
        {
            return $this->render('create', [
                'model' => $model,
            ]);
        }  
}

I'm not able to store 2nd image in folder, this code is storing 1st or 2nd image in folder, only one image is getting stored not all two, how to achieve this?

Update: **Model - **

public function rules()
    {
        return [
            [[/*'room_number','total_people', 'room_type', 'total_count', 'extra_beds', 'pic_1', 'pic_2', 'status', 'rate', 'adults_count', 'child_count'*/], 'required'],
            [['room_number','total_people','total_count', 'extra_beds', 'rate', 'adults_count', 'child_count'], 'integer'],
            [['status'], 'string'],
            [['pic_1', 'pic_2'], 'file', 'skipOnEmpty' => false, 'extensions' => 'png, jpg', 'maxFiles' => 4],
            [['room_type'], 'string', 'max' => 40],
            [['description'], 'string', 'max' => 300],
            [['pic_1', 'pic_2'], 'string', 'max' => 500]
        ];
    } 

Answer 1

Seem you have a wrong name in $model->pic_2 assignment I see /pic2/ in kmore

$model->pic_2 = 'uploads/room_pics/pic2/'.$imageName_2.'.'.$model->pic_2->extension;

$model->pic_1 = 'uploads/room_pics/'.$imageName_1.'.'.$model->pic_1->extension;

In the below lines of code the pathname don't match for me

In the second i see a pic2 for more

        $model->pic_1->saveAs('uploads/room_pics/'.$imageName_1.'.'.$model->pic_1->extension);
        $model->pic_1 = 'uploads/room_pics/'.$imageName_1.'.'.$model->pic_1->extension;

        $model->pic_2->saveAs('uploads/room_pics/'.$imageName_2.'.'.$model->pic_2->extension);
        $model->pic_2 = 'uploads/room_pics/pic2/'.$imageName_2.'.'.$model->pic_2->extension;

In the two section or don't match in saveAs or don't match in assignement and when yuo retreive the path you don't found the picture file
