How to make it so that it does not go to the page?

Question

Yii

The bottom line is this: I have a button on the page that refers to an action in the controller through which the file is downloaded. but for some reason, if the action does not send the file (in case it has not yet been generated), for some reason it throws me onto an empty page ... how to make sure that this does not happen?
