How to add a search bar to your WordPress website navigation menu without a plugin

If you have a WordPress website you may want to add a search bar to the navigation menu. You can do this without a plugin if you add this code to your functions.php file. You may want to backup your WordPress website before you make updates to the functions.php file.

/**
 * Empty trash automatically

 */
function add_search_to_nav($items, $args) {
ob_start();
get_search_form();
$searchform = ob_get_contents();
ob_end_clean();
$items .= '<li>' . $searchform . '</li>';

return $items;
}
add_filter('wp_nav_menu_items','add_search_to_nav', 10, 2);

Now if that works for you it would put a search bar in your WordPress navigation menu on there.
