How can the code be improved to ensure it functions correctly with additional forms and dropdowns?

To ensure that the code functions correctly with additional forms and dropdowns, you can modify the PHP code to dynamically handle the form submissions based on the form name. By checking the form name in the submission handling logic, you can easily add new forms without changing the existing code. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if ($_POST['form_name'] == 'form1') {
        // Handle form 1 submission
    } elseif ($_POST['form_name'] == 'form2') {
        // Handle form 2 submission
    } else {
        // Handle other forms or show an error message
    }
}
?>
