Really need help: Edit username PHP

Question

Hi! I have a School project and really need some help if that's possible, I'm getting somewhat desperate..

I need to figure out how how to edit/update a username once you have choosed one. The importance isn't that it is a name, the point is that it should work as a hotel when it's done and that you can change your name if you have typed it wrong for example. If you know a course that teaches you creating a hotel please let me know. Thanks Treehouse, you are awesome

This is how far I have gone so far:

Here's the code:

--- sessions.php ---

<head> <meta charset="utf-8"> </head> <body> Sessions

<?php session_start();

if(isset($_POST['user'])) { 
    $user = $_POST['user'];             
    $_SESSION['username'] = $user; 
} 

if(isset($_SESSION['username'])) { 

    echo "<p class='message box'>Sessions-username: " . $_SESSION['username'] . " " . 
    "<a href='logout.php' class='rightbutton'><button class='btn btn-danger'>Log out</button></a>" . 
    "</p>\n"; 
}

?>

Name: <input type="text" name="user" class="form-control"> 
<input type="submit" value="Save user" class="btn btn-info">

</form> </body> --- logout.php ---

session_start(); session_destroy();

header("Location: sessions.php");

If the user puts in the wrong user name, they could just type the correct one in and click "Save User" again. The new value will overwrite the old one and you're good to go, or at least that seems to be how the script works. Or maybe i'm misunderstanding the question. If so, please elaborate. Good luck!
