How To Create Button In Addons Setting Page

Hi,

I am trying to add a button in my addon's setting page. It is a download button.

I will pass the file name via link, and if the $_GET['file'] is same name with my log file. I will download the log file.

But now when I click download button, it's showing the content instead of downloading the file.

I think download file code is working due to when I using it without any condition. It's able to download when installing the addon.

Hope anyone can help me on this issue.

Thanks and Regards,

Mika

Use custom controller and add necessary headers before returning file
