What are the drawbacks of using JavaScript for updating input fields in PHP?

When using JavaScript to update input fields in PHP, one major drawback is that the changes made by JavaScript are not reflected in the server-side PHP code. This means that if you rely on those input fields for processing data or making decisions in your PHP script, you may encounter inconsistencies. To solve this issue, you can use AJAX to send the updated input field values to the server and update the PHP variables accordingly. 

<?php
// Check if the input field has been updated via AJAX
if(isset($_POST['updatedInput'])){
    $updatedInput = $_POST['updatedInput'];
    // Use the updated input field value in your PHP logic
}
?>
