        if ($model->load(Yii::$app->request->post()) && $model->save()) {
            $filename=$model->filename;
            $model->file= UploadedFile::getInstance($model,'file');
            $model->file->saveAs('uploads/' .$filename.'.'.$model->file->extension );

Answer 1

Declare an attribute to store the file name in the model class. Also declare a file validation rule for this attribute to ensure a file is uploaded with specific extension name.

Then, in the controller class define an action method to collect user-submitted data.

    $model = new UploadForm();
    if(isset(Yii::$app->request->post()))
    {
        $model->attributes=Yii::$app->request->post();
        $model->file=UploadedFile::getInstance($model,'file');
        if($model->save())
        {
            $model->file->saveAs('path/to/localFile');
        }
    }
