WooCommerce stock status in product widget

Find below the WooCommerce source code for the template content-widget-product.php (product widget) with some customization at the end, to get stock Status:

<?php/** * ... / ... * @see     https://docs.woocommerce.com/document/template-structure/ * @author  WooThemes * @package WooCommerce/Templates * @version 2.5.0 */if ( ! defined( 'ABSPATH' ) ) {    exit;}global $product; ?><li>    <a href="<?php echo esc_url( $product->get_permalink() ); ?>">        <?php echo $product->get_image(); ?>        <span class="product-title"><?php echo $product->get_name(); ?></span>    </a>    <?php if ( ! empty( $show_rating ) ) : ?>        <?php echo wc_get_rating_html( $product->get_average_rating() ); ?>    <?php endif; ?>    <?php echo $product->get_price_html(); ?>    <?php         // Compatibility for WC versions from 2.5.x to 3.0+        if ( method_exists( $product, 'get_stock_status' ) ) {            $stock_status = $product->get_stock_status(); // For version 3.0+        } else {            $stock_status = $product->stock_status; // Older than version 3.0        }        echo ' '.$stock_status;    ?></li>

(This code is compatible from WooCommerce version 2.5.x to 3.0+)

This code is tested and works.

You can display the product Stock quantity using WC_Product get_stock_quantity() method.

Official documentation: WC_Product method get_stock_status()

I have used this in the past to get the stock status:

get_post_meta( $product->ID, '_stock_status', true );
