  <input type='file' name='user_img' />
  <input type='text' name='username' />
  <input type='submit' name='update' value='update'>

You cannot upload files using a GET HTTP request. Files are sent in the HTTP body, which requires a POST or PUT request.

You need to do: 

<form action="someaction.php" method="post" enctype="multipart/form-data">

Add this to your form tag:

enctype = multipart/form-data

You should send your form by post method and specify that this form will have a file

<form action='' method="post" enctype="multipart/form-data"> 
  <input type="hidden" name="MAX_FILE_SIZE" value="30000" /> 
  <input type='file' name='user_img' />
  <input type='text' name='username' />
  <input type='submit' name='update' value='update'>
</form>

It is also preferable for reasons of security and performance to indicate the maximum size of files to be sent.

You need to add enctype = multipart/form-data in a form if you want to upload /use files.
