WooCommerce:结帐验证失败后更新自定义字段 [英] WooCommerce: update custom fields after checkout validation failure
问题描述
在我的项目中，我正在自定义某些WooCommerce功能.
我的送货方式"是:
1.交货
2.带走
In my project I'm customizing some of the WooCommerce features.
My "shipping methods" are:
1. delivery
2. take away
我还在结帐页面上添加了一个自定义字段，该字段是<select>，其中填充了交货(案例"1")或外卖(案例"2")的有效时间.
I also added a custom field in the checkout page that is a <select> populated with the valid times for delivery (case "1") or for the take away (case "2").
可能会发生以下情况:用户在购物车页面中选择2. take away，然后选择对"2"有效的时间，但随后更改为1. delivery，并且所选时间可能不再有效，选项列表和自定义字段标签.
It may happen that a user selects 2. take away in the cart page, then selects a time valid for "2", but then changes to 1. delivery and the selected time may not be valid anymore, neither the option list and the custom field label.
当然，我正在使用woocommerce_checkout_process挂钩通过wc_add_notice()警告用户，但是即使触发了woocommerce_checkout_fields挂钩(这也是我创建选择列表的地方)，也不会使用<select>值已更新.
Of course i'm using the woocommerce_checkout_process hook to warn the user via wc_add_notice(), but even if the woocommerce_checkout_fields hook is triggered (that's where i create the select list), the <select> values are not updated.
我认为有一个AJAX调用仅与送货方式有关，尽管触发了woocommerce_checkout_fields挂钩，但它不会更新其他结帐字段.
I think there is an AJAX call that is related only to the shipping method and doesn't update the other checkout fields, although woocommerce_checkout_fields hook is triggered.
如何更新自定义字段? 我需要一些js/jquery/AJAX吗?
How to update the custom fields? Do i need some js/jquery/AJAX?
或者:自定义字段可以与运输方式相关(并通过AJAX进行更新)吗?怎么样?
Or: can a custom field be related to a shipping method (and get updated via AJAX with it)? How?
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 $fields;
}
验证代码的构想:
add_action('woocommerce_checkout_process', 'my_checkout_date_time_validation', 30, 1);
function my_checkout_date_time_validation($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');
}
}
这是有关运送方式的信息
here's about shipping methods;
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 );
}
感谢！
推荐答案
所提供的代码几乎没有用……我进行了很多更改和优化.我所有的代码都经过注释，并且已经在WooCommerce 3+上进行了测试，并且可以正常运行.
The code provided was mostly un-useful… I have make a lot of changes and optimizations. All my code is commented, it's tested on WooCommerce 3+ and perfectly works.
您将必须添加"用于计算交付成本的极其复杂的代码" ...
1)有条件结帐现场直播活动的JAVASCRIPT
掌握客户现场活动(浏览器端)的唯一方法是javascript/jQuery.因此这并不容易，因为WooCommerce在结帐页面上已经使用了很多javascript/jQuery/Ajax ...
1) JAVASCRIPT FOR CONDITIONAL CHECKOUT FIELDS LIVE EVENTS
The only way to get the hand on customer live events (browser side) is javascript/jQuery. So this is not easy because WooCommerce use already a lot of javascript/jQuery/Ajax on checkout page…
我已将javascript代码包含在hooked函数中，但是您应该将其保存在一个单独的文件中，并使用经典的WordPress注册脚本功能来注册此脚本文件，例如在此线程中
I have included the javascript code into the hooked function, but you should save it in a separate file and register this script file with classic WordPress registering script function, like in this thread:
2)使用现有的送货方式(动态价格计算):
您无需创建任何运费.您可以使用:
2) USE EXISTING AVAILABLE SHIPPING METHODS (DYNAMIC PRICES CALCULATION):
You don't need to create any shipping rate. You can use:
- local_pickup 可供您的"TAKE WAY" 使用的方法
- flat_rate 用于交付" 的可用方法(带有动态价格计算)
- local_pickup available method for your "TAKE WAY"
- flat_rate available method for your "Delivery" (with dynamic price calculations)
对于每个送货区域，在Woocommerce>设置>送货中启用，设置并重命名(标签名称) 2种方法:
For each of your shipping zones, enable, set and rename (label name) the 2 methods in Woocommerce > Settings > Shipping:
对于固定费率，您可以设置任何最小金额(将被您的计算覆盖)…
For the flat rate you can set any minimal amount (that will be overwritten by your calculations)…
如果进行更改，则需要刷新运输缓存的数据:禁用，保存并启用，将这些方法保存到当前运输区域.
If you make changes you need to refresh shipping cached data: disable, save and enable, save those methods for the current shipping zone.
3)节省订购元数据的运输时间:
我为此添加了一些代码，并将其保存在2个自定义元字段中:
3) SAVING THE SHIPPING TIME TO ORDER META DATA:
I have add some code for that and it's save in 2 custom meta fields:
- 一个用于选择的运输方式
- 其他时间
4)在[METABOX]中显示所选的运输类型和时间(在订单编辑页面中):
我还为此添加了一些代码.
4) DISPLAYING THE CHOSEN SHIPPING TYPE AND TIME IN A METABOX (IN ORDER EDIT PAGES):
I have also add some code for that.
