In this section,let me share how to update the product attributes programmatically in wordpress.
Let's say we have a product attribute call "markup". We have to write like this in order to get the attribute correctly.
$markup_value = get_post_meta($product->post_id, '_product_attributes',true)['markup']['value'];
In order to save the attribute again, quite tricky but still managable.
$post_id = $product->post_id; $product_attr = get_post_meta(post_id, '_product_attributes',true);//get the whole product attributes first $product_attr['markup']['value'] = 50.75;//your desired attribute value update_post_meta(post_id , '_product_attributes',$product_attr);
So, that's it. If you have a list of post id, and you want to update the product attribute(in our case markup), that's how you are going to do it.
