How can the issue of not passing the ID from one PHP file to another be resolved in a form submission process?

Issue: The problem of not passing the ID from one PHP file to another in a form submission process can be resolved by using hidden input fields in the form to store and pass the ID value. 

// Form submission PHP file (form.php)
<form action="process.php" method="post">
    <input type="hidden" name="id" value="<?php echo $id; ?>">
    <!-- Other form fields -->
    <button type="submit">Submit</button>
</form>

// Process PHP file (process.php)
$id = $_POST['id'];
// Use the $id variable for further processing
