WooCommerce：结帐后验证失败更新的自定义字段(WooCommerce: update cu

在我的项目，我定制了一些WooCommerce特点。
我的“航运法”是：
1.交货
2.带走

我在结账页面是还添加了一个自定义字段<select>填充了有效时间用于递送（“1”）或用于带走（情况“2”）。

它可能发生，用户选择2. take away的车页面，然后选择一个时间有效期为“2”，但后来变为1. delivery和选择的时间可能不再有效，无论是选择列表和自定义字段标签。

当然，我使用的是woocommerce_checkout_process钩警告通过用户wc_add_notice()但即使woocommerce_checkout_fields钩被触发（这就是我创建的选择列表），在<select>未更新的值。

我认为有，虽然是只涉及到运输方式，不更新其他结账领域，AJAX调用woocommerce_checkout_fields钩被触发。

如何更新自定义字段？ 我需要一些JS / jQuery的/ AJAX？

或者：可以自定义字段相关的运输方式（并通过AJAX与它得到更新）？ 怎么样？

编辑

自定义字段代码： 

add_filter( 'woocommerce_checkout_fields', 'fty_filter_checkout_fields' );
function my_filter_checkout_fields($fields) {
    $must_deliver   =   WC()->cart->shipping_total > 0.0;   // true=deliver, false=take away

    // some complex code to calculate time lists omitted, samples array instead:

    $delivery_time_list =   array(
        "deliver 10:00",
        "deliver 11:00",
        "deliver 12:00",
        "deliver 13:00"
    );

    $takeaway_time_list =   array(
        "takeaway 10:00",
        "takeaway 10:30",
        "takeaway 11:00",
        "takeaway 11:30",
        "takeaway 12:00",
        "takeaway 12:30",
        "takeaway 13:00",
        "takeaway 13:30"
    );

    // add the new conditional field
    if($must_deliver) {
        $fields['my_delivery_datetime'] = array(
            'my_delivery_time' => array(
                'type'      => 'select',
                'options'   => $delivery_time_list,
                'required'  => true,
                'label'     => __('Delivery time')
            )
        );
    } else {
        $fields['my_delivery_time'] = array(
            'my_delivery_time' => array(
                'type'      => 'select',
                'options'   => $takeaway_time_list,
                'required'  => true,
                'label'     => __('Take away time')
            )
        );
    }

    return $fields;
}

验证码的一个想法： 

add_action('woocommerce_checkout_process', 'my_checkout_date_time_validation', 30, 1);
function my_checkout_date_time_validation($doh) {
    $time = filter_input(INPUT_POST, 'my_delivery_time');
    $shipping = filter_input(INPUT_POST, 'shipping_method', FILTER_DEFAULT, FILTER_REQUIRE_ARRAY);

    if(strpos($time, "deliver")!==FALSE && strpos($shipping[0], "local_pickup")!==FALSE) {
        wc_add_notice('Please re-select take away time', 'error');
    } else if(strpos($time, "takeaway")!==FALSE && strpos($shipping[0], "distance_based_rate")!==FALSE) {
        wc_add_notice('Please re-select delivery time', 'error');
    }

}

这里是关于运输方法; 

add_action( 'woocommerce_flat_rate_shipping_add_rate', 'add_distance_based_delivery_rate', 10, 2 );
function add_distance_based_delivery_rate( $method, $rate ) {
    $new_rate          = $rate;
    $new_rate['id']    .= ':' . 'distance_based_rate';
    $new_rate['label'] = 'delivery'; // Rename to 'Rushed Shipping'.

    // incredibly complex code used to calculate delivery costs omitted
    $dist_cost  =   1000;

    $new_rate['cost']  += $dist_cost;
    $method->add_rate( $new_rate );
}

Answer 1:

提供的代码主要是未有用......我做了很大的改变和优化。 我的所有代码都评价说，这是对WooCommerce 3+测试和完美的作品。

你将不得不添加 “用来计算省略快递费用极其复杂的代码” ...

1）对于条件CHECKOUT JAVASCRIPT FIELDS实况事件
让客户现场活动（浏览器端）的手的唯一方式是使用Javascript / jQuery的。 因此，这是不容易的，因为WooCommerce已经用了很多的JavaScript / jQuery的/阿贾克斯结帐页面上...

我已经包含的JavaScript代码到挂钩函数，但你应该把它保存在一个单独的文件和注册与经典的WordPress在这个线程注册脚本功能，像这样的脚本文件：

结帐字段：隐藏和显示现有油田

2）利用现有可用的送货方法 （动态价格计算）：
你并不需要创建任何运费率。 您可以使用：

  • local_pickup可用的方法为你的“TAKE WAY”
  • 为您的“交货” flat_rate可用的方法（动态价格计算）

对于每一个航运区，启用设置，并重新命名（标签名称）Woocommerce 2种方法>设置>航运：

对于扁平率可以设定任何最低量（即会被你的计算被覆盖）...

如果更改需要刷新航运缓存数据：禁用，保存并启用，保存当前航运区的方法。

3）节省运输时间订购META DATA：
我添加一些代码，这个和它的保存在2元的自定义字段：

  • 一个用于选择出货
  • 其他的时间

4）在显示器中METABOX所选运输类型和时间（按顺序编辑网页）：
我还添加一些代码为。

FINALY这里是代码： 

add_action( 'woocommerce_after_order_notes', 'my_custom_checkout_field' );

function my_custom_checkout_field( $checkout ) {

    // The 2 Options arrays in imput select
    $delivery_time_list[''] = $takeaway_time_list[''] = __('Select an hour');
    for($h = 10, $i = 0; $i < 8; $i++  ){
        if( $i % 2 == 0 ){
            $time = $h.':00';
            $delivery_time_list[$time] = 'deliver '.$time;
        } else {
            $time = $h.':30';
            $h++;
        }
        $takeaway_time_list[$time] = 'takeaway '.$time;
    }

    echo '<div id="delivery_checkout_fields"><h3>' . __('Shipping time options') . '</h3>';
