在Woocommerce中获得没有费用和折扣的订单总额

Question

Hi i have dynamically added some negative fees to woocommerce cart using

$woocommerce->cart->add_fee(); function. Now i want to get order total price

from WC_Order() class without counting any fee or even discounts and shipping fee.

EDIT

I don't know why i got down votes but i searched everywhere a lot and found nothing.

I tested WC_Order()::get_total() but it return zero if i the total price be $10 and i added a negative fee of $15 like this

function add_custom_fee() {
     global $woocommerce;
     $woocommerce->cart->add_fee(__('Custom', 'woocommerce'), -15);
}
add_action( 'woocommerce_cart_calculate_fees', 'add_custom_fee' );

EDIT 2

I want to get it in a hook after user submit order this is the hook

add_action('woocommerce_payment_complete','myfunc');

function myfunc($order_id) {
    $order = new WC_Order( $order_id );
    $customer = $order->get_customer_id();
    $price = $order->get_total(); // this return zero if i added fee to order
}

Answer 1

First, your code is a little outdated for the cart negative fee part:

add_action( 'woocommerce_cart_calculate_fees', 'custom_flat_discount', 20, 1 );
function custom_flat_discount( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    $cart->add_fee( __("Discount", "woocommerce"), -15 );
}

Now what you have to know is that a negative fee always apply taxes.

To get the order gran total excluding all discounts you will use the following in your function:

add_action( 'woocommerce_payment_complete', 'action_payment_complete', 20, 1 );
function action_payment_complete( $order_id ) {
    // get an instance of the WC_Order object
    $order = wc_get_order( $order_id );
    // Initialising variables
    $subtotal = $subtotal_taxes = 0; 

    // Get order items subtotal and subtotal tax
    foreach( $order->get_items() as $item ){
        $subtotal += (double) $item->get_subtotal();
        $subtotal_taxes += (double) $item->get_subtotal_tax();
    }
    // Order subtotal without any discounts, shipping…
    $order_subtotal = $subtotal + $subtotal_taxes;

    // Get order shipping totals
    $shipping_total = $order->get_shipping_total();
    $shipping_total_tax = $order->get_shipping_tax();

    // Order subtotal with shipping but without any discounts
    $order_subtotal_with_shipping = round($order_subtotal + $shipping_total + $shipping_total_tax, 2);

    // Your other code goes here
}

Alternatively you can use woocommerce_order_status_{$status_transition[to]} action hook on "processing" and "completed" paid statuses:

add_action( 'woocommerce_order_status_processing', 'action_order_status_completed', 20, 2 );
add_action( 'woocommerce_order_status_completed', 'action_order_status_completed', 20, 2 );
function action_order_status_completed( $order_id, $order ) {
    // Initialising variables
    $subtotal = $subtotal_taxes = 0; 

    // Get order items subtotal and subtotal tax
    foreach( $order->get_items() as $item ){
        $subtotal += (double) $item->get_subtotal();
        $subtotal_taxes += (double) $item->get_subtotal_tax();
    }
    // Order subtotal without any discounts, shipping…
    $order_subtotal = $subtotal + $subtotal_taxes;

    // Get order shipping totals
    $shipping_total = $order->get_shipping_total();
    $shipping_total_tax = $order->get_shipping_tax();

    // Order subtotal with shipping but without any discounts
    $order_subtotal_with_shipping = round($order_subtotal + $shipping_total + $shipping_total_tax, 2);

    // Your other code goes here
}

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