Woocommerce Bookings - 如何更改已在购物车中的项目元数据？

Question

我正在尝试更改所有可预订产品的元数据，这些产品已经在cart，更具体地说 - end_date 和持续时间，但已经好几天没有结果了...我需要在 woocommerce_before_calculate_totals 行动中完成。我试过这段代码：

if ( $my_condition ) {
    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        if ( isset( $cart_item['booking'] ) ) {
            $cart_item['booking']->set_duration( $my_new_duration );
        }
    }
}

还有成千上万种其他方式，但均未成功。

类似的方法适用于 set_price()，它会更改价格，但对于购物车中已存在的产品，可预订的产品元数据（如持续时间和结束日期）似乎无法更改！ Google 似乎对此无能为力，因为在搜索几天时我只能找到如何更改价格本身，而不是持续时间或其他元数据。

有人能帮帮我吗？谢谢！

编辑：简而言之，这就是我要实现的目标 - 假设我的购物车中有这些商品：

从 2018-05-10 10:00 到 2018-05-10 16:00
从 2018-05-10 10:00 到 2018-05-10 17:00

并且当我的函数触发时，我购物车中的这两个产品预订范围应该更改为 2018-05-10 10:00 到 2018-05-10 13:30

Answer 1

when my function triggers, both of these products booking range in my cart should change to 2018-05-10 10:00 to 2018-05-10 13:30

如果您只想设置一个固定的结束时间（例如您的示例中的13:30），那么尝试以下 function，我已经尝试并测试过它在 WordPress 4.9.5 上与 WooCommerce 3.3.5 和 WooCommerce Bookings 1.11.1.

一起正常工作

但是，产品的预订时长（在编辑产品的一般选项卡中admin 中的页面）预计是 客户定义的 {n} 小时 块；即类型为customer，单位为hour.

// Use `WC_Cart::set_cart_contents()` to actually update the cart (contents).
// See `recalc_bookings_duration()` for an example of how to use this function.
function change_booking_end_time( array &$cart_item, $end_time ) {
    if ( ! isset( $cart_item['data'] ) ) {
        return false;
    }

    if ( ! preg_match( '/^\d{2}:\d{2}$/', $end_time ) ) {
        return false;
    }

    if ( ! is_wc_booking_product( $cart_item['data'] ) ) {
        //echo 'Not a Bookable product..<br>';
        return false;
    }

    if (
        'hour' !== $cart_item['data']->get_duration_unit() ||
        'customer' !== $cart_item['data']->get_duration_type()
    ) {
        //echo 'Duration unit/type error.<br>';
        return false;
    }

    $booking_id = $cart_item['booking']['_booking_id'];
    $booking = get_wc_booking( $booking_id );

    if ( $booking ) {
        // Set the end time in 24-hour clock format.
        $new_end_time = $end_time;

        // Get the timestamp of the `$new_end_time`.
        $start_time = $booking->get_start();
        $end_time = @strtotime( $new_end_time, $start_time );
        if ( ! $end_time ) {
            return false;
        }

        // Update the booking data; in the database.
        $_end_time = (int) $booking->get_end();
        if ( $end_time !== $_end_time ) {
            $booking->set_end( $end_time );
            $booking->save();

            // Update failed.
            $_end_time = (int) $booking->get_end();
            if ( $end_time !== $_end_time ) {
                //echo '$booking->save() error.<br>';
                return false;
            }
        // The end time / duration already changed.
        } else {
            //echo 'End time already match.<br>';
            return false;
        }

        // Re-calculate the duration (number of hours).
        $duration = abs( $end_time - $start_time ) / ( 60 * 60 );
        $cart_item['data']->set_duration( $duration );

        // Check/adjust the maximum duration.
        $max_duration = $cart_item['data']->get_max_duration();
        if ( is_numeric( $max_duration ) && $duration > $max_duration ) {
            $cart_item['data']->set_max_duration( ceil( $duration ) );
        }

        // Check/adjust the minimum duration.
        $min_duration = $cart_item['data']->get_min_duration();
        if ( is_numeric( $min_duration ) && $duration < $min_duration ) {
            $cart_item['data']->set_min_duration( floor( $duration ) );
        }

        // Update the product data; in the cart.
        $cart_item['data']->apply_changes();

        // Update the booking data; in the cart.
        $cart_item['booking']['_duration'] = $duration;
        $cart_item['booking']['duration'] = $duration . ' ' .
            _n( 'hour', 'hours', $duration, 'woocommerce-bookings' );
        $cart_item['booking']['_end_date'] = $booking->get_end();

        return true;
    }
}

示例用法

add_action( 'woocommerce_before_calculate_totals', 'recalc_bookings_duration' );
function recalc_bookings_duration( WC_Cart $cart ) {
    $cart_items = $cart->get_cart_contents();
    $update_cart = false;

    foreach ( $cart_items as $cart_item_key => $cart_item ) {
        if ( change_booking_end_time( $cart_item, '13:30' ) ) {
            $cart_items[ $cart_item_key ] = $cart_item;
            $update_cart = true;
        }
    }

    if ( $update_cart ) {
        $cart->set_cart_contents( $cart_items );
    }
}
