Answer 1

In your controller change:

public function do_upload($user, $kdsmt)  //on line 32

To:

public function do_upload()

You aren't using either params in your method so there is no need to have them. More importantly, if you have declare params with a function and don't give them a default value then PHP will through an error if you don't pass anything through to them.

Hope this helps!
