Actually doing like this you wil get the file or the value you want to.

foreach ($files as $img) {   //line 81
  echo $img; // echo the Var and you will see..
}

This line -> $files = $this->multi_upload->go_upload(); probably come from a file object in your form, right? Then it must to be named like this file[] and not only file. You need to be specific that it is an Array. Otherwise nothing will happen.
