Yii2 module window where to put signup.php file?

Question

Yii

I took an example from here loco.ru/material/view?id=502
everything seems to be clear, but
6) And as
I understand it, the form presentation itself should be written to the signup.php file?
And what folder should I put it in?

Answer 1

views/<controller_name>/signup.php
in your case
views/site/signup.php
