How to change the WooCommerce add to cart success message in Quick View
When you're using WooCommerce Quick View Pro, customers can add products to the cart from the quick view lightbox. The lightbox closes automatically and they will see a WooCommerce add to cart success message - ""[Product Name]" has been added to your cart." This article explains how to change the success message.

The Quick View Pro displays the same WooCommerce add to cart success message as the rest of your store. As a result, you can change the text in your entire store, and this will also change the Quick View success message. Keep reading to learn how.
Please note: The below instructions are aimed at developers. If you don't have a developer who can implement this for you, then you can use our plugin customization service.
WooCommerce has a filter that you (or your developer) can use to change the text of the message - wc_add_to_cart_message_html
. This will change the WooCommerce add to cart success message wording throughout your store, including the quick view lightbox.
For example, you can use:
add_filter( 'wc_add_to_cart_message_html', function( $message, $products, $show_qty ) {
$message = __( 'Product added, yay!', 'my-text-domain' );
return $message;
}, 10, 3 );
