When a user unsaved a file means he doesn't uploaded to your server. the file is being in his local computer. And Its not possible to take that it from php side. unless you upload the file.

Do one thing when the user select file then upload it to your server and keep it in a temporary place and then do your job. hope this helps

As per the documentation, $_FILES is an associative array of items uploaded to the current script via the HTTP POST method. See manual

What you need to do;

  • Grab the contents of $_FILES on the initial HTTP POST.
  • Validate the image
  • Save the image to your server
  • Store the location of the saved image in the database, to be read later
  • OR
  • Use a 3rd party API

See http://www.w3schools.com/php/php_file_upload.asp

(sorry for a w3schools link)
