Change Woocommerce Sale Text for specific category only

Question

Is there a hook to change the default Woocommerce "Sale!" text to custom text, for a specific product category only, or for specific products only?

Answer 1

Use custom PHP function with hooks

function new_sale_badge() {
      if( has_term( 'category_name', 'product_cat' ) ){
      return 'New_sale_text';
      }
    }
    
    add_filter('woocommerce_sale_flash', 'new_sale_badge');

Code goes in the functions.php file of the active child theme (or active theme).
