How to get the stock quantity of an article from woocommerce?

get_sku is a method of the product class, not a global function:

$product->get_sku()

Note that this will just get the stock code, not the actual quantity, perhaps you want:

$product->get_stock_quantity()

EDIT to clarify:

<p class="stock-m13"><?php echo $product->get_stock_quantity(); ?></p>

I'm using as following.

     <?php         global $product;         $numleft  = $product->get_stock_quantity();         if($numleft==0) {           // out of stock            echo "There are no items available at this time.";         }        else if($numleft==1) {            echo "Only ".$numleft ." item left.";        }        else {            echo "Only ".$numleft ." items left.";        }     ?>

Additional

Show total sold items.

     <?php        global $post;       echo get_post_meta($post->ID, 'total_sales', true);      ?>

Hope this help.Thanks

Simply add these lines in your single.php // your template for displaying he single postOr Id you want to display it on single product page

Simply dd these lines in single-product.php in your theme directory

 global $woocommerce; foreach($woocommerce->cart->get_cart() as $cart_item_key => $values ) {    $_product = $values['data'];    if( get_the_ID() == $_product->id ) {       echo 'Quantity Is'. $values['quantity'];// quantity of the product    }   }
