Show sold out badge on WooCommerce search result

Previously we have learned how to show sold out badge on WooCommerce store and archive pages. But that method does not work on search results. We have used woocommerce_before_shop_loop_item_title action hook for store page and category/archive pages. But this hook is not available on search result page. So we will use post_thumbnail_html filter hook, which filters the post thumbnail HTML.

This may have some complexity or conflict with your theme, as your theme may already filter post_thumbnail_html. So we will use a higher priority to try to make sure that our filter gets applied at the very last.

function careless_display_woocommerce_sold_out_badge_on_search_result( $html ) {
    global $product;
    if ( $product && ! $product->is_in_stock() ) {
        return '<span class="soldout">Sold Out</span>' . $html;

    return $html;
add_filter( 'post_thumbnail_html', 'careless_display_woocommerce_sold_out_badge_on_search_result' , 9999 );

This will show the “Sold Out” text right below the product image. We will place it on top of the product image with the help of some css.

.entry-content {
    position: relative;
.soldout {
    padding: 10px 20px 10px 20px!important;
    text-align: center;
    background: #000000;
    color: white;
    position: absolute;
    top: 10px;
    font-size: 20px;
    font-weight: 500;

Code goes in the functions.php file of your active theme. And css goes in your style.css file or in your theme options (if it has an option add css).

Note: Depending on your theme, you may need to adjust css.
