Edit & Create Multiple Users

Question

Hi! I have this easy page where you can choose a username and then delete it, so it's quite a simple code. Here's a link: http://studenter.miun.se/~bjno1501/dt057g/php/moment2/practise/sessions.php

Could you show/tell me how I can add like multiple users, so it adds on line after line?

And second, how do I do if I want to edit a user but not delete it first? So there's a button at the right of every user so you have a option to edit it?

Thanks! Sorry for my english, my native language is Swedish

Here's the code:

--- sessions.php ---

<!DOCTYPE html>
<html> <head> <meta charset="utf-8"> </head> <body> <h1>Sessions</h1>

<?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"; 
    } 
?> 

<form method="post" class="form-inline"> 

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

</form> 
</body>

</html> <?php

--- logout.php ---

<?php session_start(); session_destroy();

header("Location: sessions.php");

To edit the user, just have a page for example: edit.php. In that page, just have a form so the user can edit their information. I'm guessing the user will only be able to edit their username, so once they submit the form, just do something like this:

    if(isset($_POST['submit']) && !empty($_POST['inputUsername'])) {
    // If the save button is clicked and if the input is not empty
        $_SESSION['username'] = $_POST['inputUsername'];
    }

In edit.php:

    <form action="" method="post">
        <input type="text" name="inputUsername">
        <button type="submit" name="submit">Save</button>
    </form>

Any problems please comment below :)

Hi! Thanks for helping me out :) I copied your code and added it to a new page named it edit.php.

I have a problem adding the code, how should I include it? I tried to add the edit-page here in the sessions-page where the text comes up when a new user is added:

<!DOCTYPE html>
<html> <head> <meta charset="utf-8"> </head> <body> <h1>Sessions</h1>

<?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>
         <a href='edit.php'><button>Edit</button></a>" .
        "</p>\n";
    }
?>

<form method="post" class="form-inline">

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

</form>
</body>

</html> <?php
