Media file uploading

Hello to everybody!

Please help me guys I’m beginner in Yii2 and got troubles with media file uploading…

Ex. of my script

if ($model->load(Yii::$app->request->post()) && $model->save()) {


  


   $model->videoFile = UploadedFile::getInstance($model, 'videoFile');

    $image->saveAs('uploads/' . $image->baseName . '.' . $image->extension);
