WooCommerce: Add class to notice

Question

I want to add an extra class to my WooCommerce notice.

Here's my current code for printing the notice:

wc_print_notice( 'My message', 'success' );

I saw in the WooCommerce Docs, that there is an option to add extra $data to the notice.

But something like this won't work (it adds only data-class="extra" to it):

wc_print_notice( 'My message', 'success', array('class' => 'extra') );

Is there an option to do this or am I misunderstanding something?

Answer 1

I found an optional solution for my case. It would be possible to simply style the notice with the data attribute. Like this:

.woocommerce-message[data-class="extra"] {
    background-color: red;
}
