WP 5.3.3
创建订单后,我需要以编程方式更改运输成本。
此代码不影响:
add_action('woocommerce_new_order', 'custom_shipping_costs', 1, 1);
function custom_shipping_costs($order_id)
{
$order = wc_get_order($order_id);
$shippingItems = (array) $order->get_items('shipping');
foreach ($shippingItems as $item) {
$item->cost = 0;
}
$order->save();
}
请帮忙吗?
更新1:
重要的是,我需要在每n个订单中更改运费。像这样的东西:
if ($order_id % 10 == 0) {
// change shipping price for every 10-th order
}
更改运费的简单方法是:
add_filter( 'woocommerce_package_rates', 'woocommerce_package_rates' );
function woocommerce_package_rates( $rates ) {
foreach($rates as $key => $rate ) {
$rates[$key]->cost = 10;
}
return $rates;
}
如果有数量或总价,则添加条件说明
add_filter( 'woocommerce_package_rates', 'woocommerce_package_rates', 10, 2 );
function woocommerce_package_rates( $rates, $package ) {
$new_cost = ( WC()->cart->subtotal < 10 ) ? 4.5 : 2.5;
foreach($rates as $key => $rate ) {
$rates[$key]->cost = $new_cost;
}
return $rates;
}
首先为订单ID不连续] >>,因为它们基于在Wordpress页面,帖子和所有其他自定义帖子(如Woocommerce产品和优惠券)上也使用的帖子ID。因此,我们需要对您的WooCommerce订单启用顺序计数,才能对每10个订单进行更改。
在将订单数据保存到数据库之前下订单时,以下将每10个订单的运输成本设置为零:
// Set a count based on placed orders for shipping items cost change add_action( 'woocommerce_checkout_create_order', 'action_wc_checkout_create_order', 10, 2 ); function action_wc_checkout_create_order( $order, $data ) { $orders_count = (int) get_option('wc_orders_count_for_shipping'); // get $order count for shipping item change // Increase count for next order (starting count at 2 as this hook is triggered after shipping items hook) set_option('wc_orders_count_for_shipping', $orders_count > 0 ? $orders_count + 1 : 2 ); } // Set shipping cost to zero every 10-th orders when order is placed add_action( 'woocommerce_checkout_create_order_shipping_item', 'action_wc_checkout_create_order_shipping_item', 10, 4 ); function action_wc_checkout_create_order_shipping_item( $item, $package_key, $package, $order ) { $orders_count = (int) get_option('wc_orders_count_for_shipping'); // Every 10-th orders if( $orders_count > 0 && ( $orders_count % 10 ) === 0 ) { $item->set_total( '0' ); $item->set_taxes( [ 'total' => '0' ] ); $item->set_total_tax( '0' ); } }
代码进入您的活动子主题(或活动主题)的functions.php文件中。应该可以。
