How do I use things like $email and $image in sessions when I only use username and password to log ind. It seems like I only can use $username ()

I don't know how to collect the last user info to sessions?

server.php

<?php 

session_start();



// variable declaration

$username = "";

$email    = "";

$errors = array(); 

$_SESSION['success'] = "";





// connect to database

$db = mysqli_connect('Localhost', 'user', 'pass', 'db');



// REGISTER USER

if (isset($_POST['reg_user'])) {

    // receive all input values from the form

    $username = mysqli_real_escape_string($db, $_POST['username']);

    $email = mysqli_real_escape_string($db, $_POST['email']);

    $password_1 = mysqli_real_escape_string($db, $_POST['password_1']);

    $password_2 = mysqli_real_escape_string($db, $_POST['password_2']);



    $uploaddir = 'assets/images/users/';

    $image = $uploaddir . basename($_FILES['userfile']['name']);



    move_uploaded_file($_FILES['userfile']['tmp_name'], $image);

index.php

<?php 

session_start();



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

    $_SESSION['msg'] = "You must log in first";

    header('location: pages-login.php');

}



if (isset($_GET['logout'])) {

    session_destroy();

    unset($_SESSION['username']);

    header("location: pages-login.php");

}



?>



...



<?php if (isset($_SESSION['success'])) : ?>

                                        <div class="success" >

                                            <h3>

                                                <?php 

                                                    echo $_SESSION['success']; 

                                                    unset($_SESSION['success']);

                                                ?>

                                            </h3>

                                        </div>

                                    <?php endif ?>



                                    <ol class="breadcrumb">

                                        <li class="breadcrumb-item active">



                                            <!-- logged in user information -->

                                            <?php  if (isset($_SESSION['username'])) : ?>

                                                <p>Hej <strong><?php echo $_SESSION['username']; ?>! </strong>Velkommen til Kommandocentralen</p>

                                            <?php endif ?>



                                            <?php echo $_SESSION['email']; ?>!



                                        </li>

                                    </ol>

I can not get it to give $email the same way it gives me $username.

I cut out a lot of the code between the php-bits

Following the same guidlines of the tutorial, on the server.php page, when the user registers or login, after the line that says $_SESSION['username'] = $username;, you can add other session data after that as follows:

When registering the user:

// REGISTER USER

if (isset($_POST['reg_user'])) {

    ...

    $_SESSION['username'] = $username;

    $_SESSION['email'] = $email;

    ...

}

When the user logs in:

// LOGIN USER

if (isset($_POST['login_user'])) {

    ...

    $row = $results->fetch_array();



    $_SESSION['username'] = $username;

    $_SESSION['email'] = $row['email'];

    ...

}

For the user login, $results[0]['email'], references the email column of your database table so whichever data you want to make available, will need to use the same as is in the tabla. For example you would reference the image column as $results[0]['image'].

All other session variables can be set following the above pattern.

Hope this helps.

yes it worked - it stored the image in the folder I requested. but now I'm not sure how to show it?

    // REGISTER USER

...

$uploaddir = 'assets/images/users/';

$image = $uploaddir . basename($_FILES['userfile']['name']);



move_uploaded_file($_FILES['userfile']['tmp_name'], $image);

...

$_SESSION['username'] = $username;

$_SESSION['email'] = $email;

$_SESSION['userfile'] = $image;

...



    // LOGIN USER

...

$row = $results->fetch_array();

...

$_SESSION['username'] = $username;

$_SESSION['email'] = $row['email'];

$_SESSION['userfile'] = $row['userfile'];

...

And then in the index.php

...    

<img src="<?php echo $_SESSION['userfile']; ?>" />

...

But nothing shows - can you se what my error is?
