What are some alternative methods for transferring only the filled-in form fields to a PHP script, rather than all fields, in a jQuery calculation form?

When working with a jQuery calculation form, you may want to transfer only the filled-in form fields to a PHP script instead of all fields to optimize data processing. One alternative method to achieve this is by using jQuery to dynamically serialize only the filled-in form fields and send them via AJAX to the PHP script for processing. 

<?php
// Retrieve the serialized form data sent via AJAX
$form_data = $_POST['form_data'];

// Decode the JSON string into an associative array
$form_fields = json_decode($form_data, true);

// Process the filled-in form fields as needed
foreach ($form_fields as $field_name => $field_value) {
    // Perform calculations or store data in database
    echo $field_name . ': ' . $field_value . '<br>';
}
?>
