如何在functions.php中使用WooCommerce Duplicate Product Class

Question

I am trying to use http://docs.woothemes.com/wc-apidocs/source-class-WC_Admin_Duplicate_Product.html#15-235 in functions.php but it does not work.

$wcx = new WC_Admin_Duplicate_Product;
$product = $wcx->duplicate_product('14466'));
print_r($product);

This gives me a blank page

You need to use a wordpress post object as the parameter, not the post ID. Example:

$wc_adp = new WC_Admin_Duplicate_Product;
$product = $wc_adp->product_duplicate( get_post( '14466' ) );
print_r( $product );
