Try adding `enctype="multipart/form-data"` to your form element. http://stackoverflow.com/questions/4526273/what-does-enctype-multipart-form-data-mean — chris85, Jun 30 '15 at 04:09
Did you just updated your question instead of asking here about the previous comment? If the form doesn't submit the file the index isn't going to exist. or I guess you could do an empty/isset check seems kind of pointless though when you could just resolve the issue... you also could turn off error reporting or suppress the error (routes I wouldn't take). — chris85, Jun 30 '15 at 04:14

You form should have enctype="multipart/form-data" as the form element.

So you should have

<form action="#" method ="POST" enctype="multipart/form-data">

If the contents of a file are submitted with a form, the file input should be identified by the appropriate content type (e.g., "application/octet-stream")

Note :

Remove the # symbol from the form element as it is not required.

The enctype attribute specifies how the form-data should be encoded when submitting it to the server.The enctype attribute can be used only if method="post".

<body>
    <center>
    <form action="#" method ="POST" enctype="multipart/form-data">
     // Your Code
      </form>

  </center>
 </body>

<form action="#" method ="POST" enctype="multipart/form-data">
   //Your form Code
</form>

enctype="multipart/form-data" this will allow your form to submit file (image, pdf,office files, etc...)

Extra Note

in php.ini (in line 912)

file_uploads=On
