How to access a controller action in yii2?

Question

Yii

I need this action to be processed in the same way as with an Ajax request (
or rather, that ( Yii::$app->request->isAjax) would work).

Answer 1

See how the getIsAjax() method works, and then add what you need to the request (header||parameter).

Answer 2

A question the answer. Move the code that executes if Yii::$app->request->isAjax is true to a separate method and call it where necessary. Just.
If not, specify the question - what exactly and how you want it to work.
