title: How to pass data from form without a form field? (PHP)
body: <p>I have a form for editing a users name and email.
  So when it updates the name and email, it needs the username to identify which row it should update.</p>
  
  <p>So i wanted to know if there is any element which is passed with the form but without showing the value or being editable in the input tag.</p>
  
  <p>So i get the username from one script.
  The edit user script gets the name and email from the database with the specified username.
  Then it passes that new name and email with the username to another script which updates it.</p>
