Try adding enctype="multipart/form-data" to your form element. stackoverflow.com/questions/4526273/… — chris85

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

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.

Do not use w3schools for all your basic learning, try using PHP The Right Way

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
