通过WooCommerce中的钩子有条件地改变产品税类

I have implemented a b2b area into my WooCommerce Shop about 18 months ago. Recently I have updated all plugins and wordpress itself. Switching the tax class on variable products doesn't work anymore. The code below worked so far, but stopped working. What am I missing?

add_filter('woocommerce_product_get_price', 'switch_price', 99, 2);
add_filter('woocommerce_product_variation_get_price', 'switch_price', 99, 2);
function switch_price($price, $product){

    if(isset($_COOKIE["customerType"])){
      if($_COOKIE["customerType"] == "business"){
          $product->set_tax_class("Zero Rate");
      }
    }

    return $price;
}

    To make it work, you will better target the WC_Product method get_tax_class() through dedicated related composite hooks, this way:

    add_filter('woocommerce_product_get_tax_class', 'switch_product_tax_class', 100, 2 );
    add_filter('woocommerce_product_variation_get_tax_class', 'switch_product_tax_class', 100, 2 );
    function switch_product_tax_class( $tax_class, $product ){
        if( isset($_COOKIE["customerType"]) && $_COOKIE["customerType"] == 'business' ){
            return "Zero Rate";
        }
        return $tax_class;
    }
    

    Code goes in functions.php file of your active child theme (or active theme). Tested and works.


    Based on WC_Customer is_vat_exempt property, you could also try to use the following instead:

    add_action( 'template_redirect', 'vat_exempt_b2b_customers' );
    function vat_exempt_b2b_customers() {
        if( isset($_COOKIE["customerType"]) && $_COOKIE["customerType"] === 'business' 
        && ! WC()->customer->is_vat_exempt() ){
            WC()->customer->set_is_vat_exempt( true );
        }
    }
    

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