但是没有返回任何值。
如何获得购物车税总额?
从本质上讲,我希望为用户计算税金,但是由于客户将支付COD税金,因此减少了税金。
完整代码如下:
add_action( 'woocommerce_calculate_totals', 'action_cart_calculate_totals', 10, 1 );
function action_cart_calculate_totals( $cart_object ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
    if ( !WC()->cart->is_empty() ):
        $cart_object->cart_contents_total *= .10 ;
    endif;
}
//Code for removing tax from total collected
function prefix_add_discount_line( $cart ) {
  global $woocommerce;
  $discount = $woocommerce->cart->tax_total;
  $woocommerce->cart->add_fee( __( 'Tax Paid On COD', 'your-text-domain' ) , - $discount );
}
add_action( 'woocommerce_cart_calculate_fees', 'prefix_add_discount_line' );

    global $woocommerce; $woocommerce->cart购物车已过时。使用WC()->cart代替。$cart (对象)参数。taxes不是tax_total。要实现您想要的代码,您的代码将是:
// For Woocommerce 2.5+ (2.6.x and 3.0)
add_action( 'woocommerce_cart_calculate_fees', 'prefix_add_discount_line', 10, 1 );
function prefix_add_discount_line( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;
    $discount = 0;
    // Get the unformated taxes array
    $taxes = $cart->get_taxes(); 
    // Add each taxes to $discount
    foreach($taxes as $tax) $discount += $tax;
    // Applying a discount if not null or equal to zero
    if ($discount > 0 && ! empty($discount) )
        $cart->add_fee( __( 'Tax Paid On COD', 'your-text-domain' ) , - $discount );
}

代码在您的活动子主题(或主题)的function.php文件中,或者在任何插件文件中。
此代码已经过测试并且可以工作。
