html - How can I hide the value from a input, so that the value is still accesable but won't be displayed?

Question

I have a simple input form from the type submit and it contains the value $username:

<form action="index.php" method="POST">
     <input class="submit" type="submit" name="submitbtn" value="'.$username.'">
</form>

How can I hide the value, so that it will not be displayed on index.php, but I still can access this value?

To hide fields in form from displaying change their type to hidden. Keep in mind that hidden field is just not displayed but anyone can read it/change it with browser devtools.

<form action="index.php" method="POST">
     <input type="hidden" name="user_name" value="'.$username.'">
     <input class="submit" type="submit" name="submitbtn" value="Submit">
</form>
