code challenge

A visitor to our site has just performed a search for chocolate, which has returned no results. Change this code to display the search term in the search box again, making sure to protect the page against malicious code that might have been entered.

index.php 
<?php

require_once("inc/config.php");

$search_term = "";
if (isset($_GET["s"])) {
    $search_term = trim($_GET["s"]);
    if ($search_term != "") {
        require_once(ROOT_PATH . "inc/products.php");
        $products = get_products_search($search_term);
    }
}

$pageTitle = "Search";
$section = "search";
include(ROOT_PATH . "inc/header.php"); ?>

    <div class="section shirts search page">

        <div class="wrapper">

            <h1>Search</h1>

            <form method="get" action="./">

              <input type="text" name="s" value="<?php if(isset($s)) {echo htmlspecialchars($s); } ?>">
              <input type="submit" value="Go">
            </form>

            <?php

                if ($search_term != "") {
                    if (!empty($products)) {
                        echo '<ul class="products">';
                        foreach ($products as $product) {
                            echo get_list_view_html($product);
                        }
                        echo '</ul>';
                    } else {
                        echo '<p>No products were found matching that search term.</p>';
                    }
                }

            ?>

        </div>

    </div>

<?php include(ROOT_PATH . "inc/footer.php"); ?>

There is no $s. Its originally $_GET['s'], which you stored in $search_term
