What are the potential pitfalls of using JavaScript to handle form submission with multiple buttons in PHP?

When using JavaScript to handle form submission with multiple buttons in PHP, a potential pitfall is that users can bypass the JavaScript validation and submit the form directly, leading to unexpected behavior. To solve this issue, you can add server-side validation in PHP to ensure that the form is submitted correctly. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST["button1"])) {
        // Handle button1 submission
    } elseif (isset($_POST["button2"])) {
        // Handle button2 submission
    } else {
        // Handle form submission without clicking any button
    }
}
?>
