What are some alternatives to using sessions for managing form data submission to different PHP files?

Using sessions for managing form data submission to different PHP files can lead to potential security risks and can also be cumbersome to manage. One alternative approach is to use hidden input fields in the form to pass data between pages. This way, the form data is directly submitted along with the form request and can be accessed in the receiving PHP file without the need for sessions. 

// Form page (form.php)
<form action="process.php" method="post">
    <input type="text" name="username" placeholder="Username">
    <input type="hidden" name="hiddenField" value="someValue">
    <button type="submit">Submit</button>
</form>

// Processing page (process.php)
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST['username'];
    $hiddenField = $_POST['hiddenField'];
    
    // Process the form data
}
?>
