PHP display name of login user

I want to display the name of the logged in user, but since there is no field to input name when logging in, the session only gets the email and password values. How can I display name?
my server.php
<?php
include_once "inc/user-connection.php";
session_start();
$name = mysqli_real_escape_string($conn, $_POST['name']);
$password = mysqli_real_escape_string($conn, $_POST['password']);
$hashed_password = password_hash($password, PASSWORD_DEFAULT);
$email = mysqli_real_escape_string($conn, $_POST['email']);
$username = mysqli_real_escape_string($conn, $_POST['username']);
if (isset($_POST['admin-sign-in'])) {
if (!empty($email)) {
if (!empty($password)) {
$sql = 'SELECT email, password FROM admin WHERE email = ?';
// preparing the SQL statement
if ($stmt = $conn->prepare($sql)) {
$stmt->bind_param('s', $_POST['email']);
$stmt->execute();
$stmt->store_result(); // Store the result so we can check if the account exists in the database.
// If email exists in sign_up table
if ($stmt->num_rows > 0) {
$stmt->bind_result($email, $password);
$stmt->fetch();
// if password user enters matches the one in the database
if (password_verify($password, $hashed_password)) {
$query = mysqli_query($conn, $sql);
$row = mysqli_fetch_array($query);
$_SESSION['name'] = $row['name'];
// upon successful login, redirect user to landing apge
header("location: dashboard.php");
die();
} else {
// Incorrect password
header("location: ../html/sign-in-error.html");
die();
}
} else {
// Incorrect username
header("location: ../html/sign-in-error.html");
die();
}
$stmt->close();
}
} else {
header("location: ../html/404-error.html");
die();
}
} else {
header("location: ../html/404-error.html");
die();
}
}
my dashboard.php
<?php
session_start();
?>
<div class="d-block">
<h1 class="lead fw-normal text-muted mb-4 px-lg-10">Hello, <?php echo $_SESSION['name']; ?></h1>
</div>
sign-in page
Dashboard: should display first and last name but is empty(It can display email, but I don't want that)
The $name variable contains both first and last name, there is only one column for name in the table.

Like commented on your question, when doing the sign in, just fetch the names from the database when you check user login details and to ease your pain you can store these names to your $_SESSION so you can call it whenever you need it if the session is up.
$_SESSION['first_name'] = $name;
Should not be harder than that. Only thing confusing was that you store your sign ups to different table than you use in sign in, but there seems to be admin and user tables seperately.
Offtopic: You could just add column to your users table for like admin with BOOLEAN or rank with actual rank name
