您最好根据支付网关(此处为您的 Paypal)添加费用,如下所示:
// Add a fee of 10.00 when Paypal is chosen
add_action( 'woocommerce_cart_calculate_fees', 'custom_paypal_additional_fee', 20, 1 );
function custom_paypal_additional_fee( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if( WC()->session->get( 'chosen_payment_method' ) == 'paypal' )
$cart->add_fee( __( 'Paypal fee', 'woocommerce' ), 10.00 );
}
// Add the information on checkout paypal text gateways section
add_filter('woocommerce_gateway_icon', 'custom_paypal_gateway_text', 20, 2 );
function custom_paypal_gateway_text( $html, $gateway_id ) {
if( $gateway_id == 'paypal' )
$html .= ' <small class="paypal-fee">(+ '.wc_price(10.00).')</small>';
return $html;
}
// Enable ajax update checkout event when choosing a gateway to refresh the fee
add_action('wp_footer', 'payment_gateways_update_checkout_event' );
function payment_gateways_update_checkout_event() {
?>
<script type="text/javascript">
(function($){
$('form.checkout').on( 'change', 'input[name^="payment_method"]', function() {
var t = { updateTimer: !1, dirtyInput: !1,
reset_update_checkout_timer: function() {
clearTimeout(t.updateTimer)
}, trigger_update_checkout: function() {
t.reset_update_checkout_timer(), t.dirtyInput = !1,
$(document.body).trigger("update_checkout")
}
};
$(document.body).trigger('update_checkout')
});
})(jQuery);
</script>
