什么，我试图完成的：在woocommerce，我需要通过AJAX相应检查通过，当用户选择日期的日期选择器领域的交付日期，然后更新运输选项，让事情当他们是不恰当的。像免费送货，可拍摄出

What i'm trying to accomplish: In woocommerce, I need to check a date delivered via a datepicker field when user selects a date, and then update shipping options accordingly via ajax, so that things like free shipping can be taken out when they are not appropriate.

我目前知道/想通了：我现在有jQuery的事件发射，并通过日期自定义脚本，这是有点儿，我需要做的发送。我一直没能找到只返回航运数据woocommerce类中的函数，所以我不认为我可以调用，并返回一个片段，因为他们的结账已经这样做了。

What I currently know/have figured out: I currently have the jQuery event firing and sending through a date to a custom script, which is kinda where I need to do. I have not been able to find a function within woocommerce classes that returns just the shipping data, so I don't think I can call that and return it as a fragment, as they do for the checkout already.

不过，我也发现，

WC_AJAX::update_order_review()

已经在它的行动电话，我已经成功地勾住了功能上的行动，我已经能够关火

has an action call within it, and I have successfully hooked a function onto that action, AND i've been able to fire off the

t( 'body' ).trigger( 'update_checkout' );

这触发了一个更新结帐检讨块的动作。

which fires off the action that updates the checkout review block.

我真正的问题：这一切是伟大的，I'ts看起来像它的方向是正确的航向，但我不知道woocommerce不够好，知道如何让内部的运输方式我迷上行动，他们在必要时取消设置。有谁知道，如果我可以通过$ woocommerce全局对象得到他们，然后让他们被那个WC_AJAX方法??

My real question: All this is great, and I'ts looking like its heading in the right direction, but I don't know woocommerce well enough to know how to get the shipping methods within my hooked action to unset them as necessary. Does anyone know if I can get them through the $woocommerce global object, and then have them be read by the rest of that WC_AJAX method??

在这里任何帮助将是很大的AP preciated。

Any help here would be greatly appreciated.

**注：是的，我知道，那是一个​​T，而不是一个$的jQuery的。不是一个错误

** notes: yes, I know thats a 't' and not a '$' in the jQuery. Not a mistake

推荐答案

因此​​，对于那些你们谁需要这一点，就需要一点点finagling在woocommerce，的方式，因为他们处理的车/结帐值输出运费和付款方式，但最终，我可以做到这一点使用woocommerce的钩子，很少插件的修改，因此，一个pretty的清洁解决方案。

So, for those of you who may need this, it required a little finagling in woocommerce, because of the way they handle output of cart/checkout values for shipping and payment options, but in the end, I could make it happen using woocommerce's hooks, and very little plugin modification, so, a pretty clean solution.

基本上我所做的就是利用woocommerce会议，两个挂钩，和一个JavaScript触发器，刷新结账订单审核。

Basically what I did was use woocommerce sessions, two hooks, and a javascript trigger that refreshes the checkout order review.

通过的 woocommerce_checkout_update_order_review 挂钩，发生在 WC_AJAX :: update_order_review 和使用前述方式的组合 $（'身体'）.trigger（'update_checkout'）; 电话，我可以钩到该更新结帐检讨块的动作。到目前为止好。

Through a combination of the woocommerce_checkout_update_order_review hook that happens in the WC_AJAX::update_order_review and use of the aformentioned $( 'body' ).trigger( 'update_checkout' ); call, I could hook in to the action that updates the checkout review block. So far so good.

我在这个函数所做的是检查是否领域已拥有一个值，如果它这样做，将其保存在 WC（） - ＆GT;会议。然后，因为 WC_AJAX :: update_order_review 通话 woocommerce_order_review（）来获取所有更新的车和运输方法，我看着与函数模板关联，并发现了另一个挂钩， woocommerce_review_order_before_shipping ，这让我修改的运送方式的车模板遍历并建立运输方式在之前 wc_cart_totals_shipping_html（）。

What I did in this function was check if the field had a value, and if it did, save it in the WC()->session. THEN, since WC_AJAX::update_order_review calls woocommerce_order_review() to grab all the updated cart and shipping methods, I looked into the template associated with that function and found another hook, woocommerce_review_order_before_shipping, which allows me to modify the shipping methods before the cart template loops through and builds the shipping options in wc_cart_totals_shipping_html().

现在，我知道，你在想，等一下，我需要结账的发运方式，没有车的人，但在现实中，他们似乎是同一个。

Now, I know, you're thinking, wait, I need checkout shipping methods, not cart ones, but in reality, they seem to be one and the same.

希望我浪费的时间会帮助别人有类似的问题。

Hopefully my wasted hours will help someone else with a similar problem.

干杯。
