  //need to create object, but using sku cannot create a object, 
  $product = new WC_Product($sku); 
  echo $product->get_price_html();
}

is there way to get product id before create object, then i can pass the product id to WC_Product class constructor and create object.thank you

Answer 1

WooCommerce 2.3 finally adds support for this in core.

If you are using this version, you can call

wc_get_product_id_by_sku( $sku )

Answer 2

You can use this function (found here). Google is your friend!

function get_product_by_sku( $sku ) {

    global $wpdb;

    $product_id = $wpdb->get_var( $wpdb->prepare( "SELECT post_id FROM $wpdb->postmeta WHERE meta_key='_sku' AND meta_value='%s' LIMIT 1", $sku ) );

    if ( $product_id ) return new WC_Product( $product_id );

    return null;
}
