set_value() is working but set_select() not working

If i use fill() method, how i can process the uploaded doc file ?

Oh, I didn't notice that you used the getFile() method. Which brings me to wonder how you were or wanted to save the doc file in the database?

I want to move to the local folder and save the path into the doc_file field in database, that i can manage to do but im in trouble with set_select() function. I didnt understand what is making wrong, everything seems to be correct.
