How can JavaScript be utilized to filter and display only relevant data based on user selections in PHP forms?

To filter and display only relevant data based on user selections in PHP forms, JavaScript can be utilized to dynamically update the content without refreshing the page. This can be achieved by creating event listeners on the form elements to capture user selections and then making AJAX requests to the server to fetch and display only the relevant data. 

<?php
// PHP code to fetch and display relevant data based on user selections

// Check if form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Get user selections from form
    $category = $_POST['category'];
    $location = $_POST['location'];

    // Perform database query based on user selections
    // Replace this with your own database query
    $query = "SELECT * FROM products WHERE category = '$category' AND location = '$location'";
    $result = mysqli_query($conn, $query);

    // Display the relevant data
    while ($row = mysqli_fetch_assoc($result)) {
        echo "<div>{$row['product_name']}</div>";
    }
}
?>
