如何计算Woo-commerce的add_fee总价值(sum)

Question

例如，我使用add_fee表单使用多个折扣

$wc_cart->add_fee( sprintf(__('fee 1', 'fee1') )."", -10, false );
$wc_cart->add_fee( sprintf(__('fee 2', 'fee1') )."", -20, false );
$wc_cart->add_fee( sprintf(__('fee 3', 'fee1') )."", -30, false );

我想计算并显示整个add_fee值的总和，如下所示

Total fee : 60

如何从Woo-commerce获得add fee价值。

提前谢谢。

Answer 1

您可以使用下面的过滤器来计算add_fee()总数，请检查并添加费用2和费用3:这只是一个例子，您可以根据需要修改代码

add_action( 'woocommerce_cart_calculate_fees','woocommerce_custom_surcharge' );
function woocommerce_custom_surcharge() {
global $woocommerce;

if ( is_admin() && ! defined( 'DOING_AJAX' ) )
    return;

    $percentage = 0.03;
    $taxes = array_sum($woocommerce->cart->taxes);
    $surcharge = ( $woocommerce->cart->cart_contents_total + $woocommerce->cart->shipping_total + $taxes ) * $percentage;   
    // Make sure that you return false here.  We can't double tax people!
    $woocommerce->cart->add_fee( 'Fee 1', $surcharge, false, '' );

}

Answer 2

您可以使用以下代码来获取所有费用并在购物车小计后显示，

<?php
function get_all_fees() {
    $fee_object = WC()->cart->fees_api();
    $allfeedata = $fee_object->get_fees();
    $totalfee = array_sum(array_column($allfeedata, 'amount'));
    ?>
                    <tr class="fee-total">
                <th><?php esc_html_e('Total Fee', 'woocommerce'); ?></th>
                <td data-title="<?php esc_attr_e('Total Fee', 'woocommerce'); ?>"><?php echo absint($totalfee); ?></td>
            </tr>
    <?php
}

add_action('woocommerce_cart_totals_before_order_total', 'get_all_fees');
?>
