I have some custom attributes for each product in woocommerce, I can edit them at the Attributes tab. I can also read them using this code
$product = new WC_Product($product_id);
$v = $product->get_attribute(‘myattr_name’);
But I don’t understand how to set this attribute value. Googling not helps. Do you know? I am looking for something like this
But as I can see, there is no such method.
