Add extra meta for orders in Woocommerce
提问by Mo Saeedi
I'm creating a custom plugin for my website.
我正在为我的网站创建一个自定义插件。
In some part of this plugin I need to store extra meta in wp_postmeta
for each orders.
在这个插件的某些部分,我需要wp_postmeta
为每个订单存储额外的元数据。
I added this in my plugin's class:
我在我的插件类中添加了这个:
add_action ('woocommerce_before_checkout_process', array( &$this, 'add_item_meta', 10, 2) );
And this is add_item_meta()
function:
这是add_item_meta()
功能:
function add_item_meta( $item_id, $values ) {
wc_add_order_item_meta($item_id, '_has_event', 'yes' );
}
This function is not complete, but nothing happens with this codes; I think I need to use another hook but I can't find a proper one.
此功能不完整,但此代码没有任何反应;我想我需要使用另一个钩子,但我找不到合适的钩子。
Does anyone know anything about this?
有人对这个有了解吗?
I also have another problem with $item_id
: this is woocommerce global variable but I can't see it in my plugin!
我还有另一个问题$item_id
:这是 woocommerce 全局变量,但我在插件中看不到它!
I mean I don't have access to this variable from my plugin or something like this!
我的意思是我无法从我的插件或类似的东西访问这个变量!

The 2018 way:
2018年的方式:
Built on Guido W.P.answer you can use instead woocommerce_checkout_create_order
action hook in
a more lighter and effective version code (using WC 3+ CRUD methods):
基于Guido WP答案,您可以woocommerce_checkout_create_order
在更轻量和更有效的版本代码中使用动作钩子(使用WC 3+ CRUD 方法):
add_action('woocommerce_checkout_create_order', 'before_checkout_create_order', 20, 2);
function before_checkout_create_order( $order, $data ) {
$order->update_meta_data( '_custom_meta_key', 'value' );
}
Code goes in function.php file of your active child theme (or active theme).
代码位于活动子主题(或活动主题)的 function.php 文件中。
Tested and works in WooCommerce 3+ (only).
在 WooCommerce 3+ (仅)中测试和工作。
SOME EXPLANATIONS:
一些解释:
The woocommerce_checkout_create_order
action hook is just one step before saving the order data. See below in an extractof the WC_Checkout
create_order()
method (with both hooks):
该woocommerce_checkout_create_order
行动钩保存订单数据前,只需一个步骤。请参阅下面的方法摘录WC_Checkout
create_order()
(带有两个钩子):
/**
* Action hook to adjust order before save.
* @since 3.0.0
*/
do_action( 'woocommerce_checkout_create_order', $order, $data );
// Save the order.
$order_id = $order->save();
do_action( 'woocommerce_checkout_update_order_meta', $order_id, $data );
return $order_id;
Why using
woocommerce_checkout_create_order
instead?:
- Because You don't need to use
$order = wc_get_order( $order_id );
as you already got$order
as an argument in the hooked function.- You don't need to use
$order->save();
as this will be done just after anyway (see the source code)- Also
woocommerce_checkout_create_order
has been released in WooCommerce version 3 and it's maid for that too.So this just works with a single line of codeinside the function.
为什么用
woocommerce_checkout_create_order
呢?:
- 因为您不需要使用,
$order = wc_get_order( $order_id );
因为您已经$order
在挂钩函数中作为参数使用。- 您不需要使用,
$order->save();
因为无论如何这都会完成(请参阅源代码)- 也
woocommerce_checkout_create_order
已在 WooCommerce 版本 3 中发布,它也是如此。所以这只适用于函数内的一行代码。

Building on Mo Saeedi answer, I believe this snippet is more in line with the new CRUD approachintroduced by WooCommerce 3.0:
基于 Mo Saeedi 的回答,我相信这个片段更符合WooCommerce 3.0 引入的新 CRUD 方法:
add_action('woocommerce_checkout_update_order_meta',function( $order_id, $posted ) {
$order = wc_get_order( $order_id );
$order->update_meta_data( 'my_custom_meta_key', 'my data' );
$order->save();
} , 10, 2);

answer is:
I should use woocommerce_checkout_update_order_meta
for add_action and also i should simply use update_post_meta()
to add extra meta to my order
答案是:我应该woocommerce_checkout_update_order_meta
用于 add_action 并且我应该简单地用于update_post_meta()
向我的订单添加额外的元数据
function add_item_meta( $order_id ) {
//global $woocommerce;
update_post_meta( $order_id, '_has_event', 'yes' );
}

The 2016 way:
2016年的方式:
add_action('woocommerce_checkout_update_order_meta',function( $order_id, $posted ) {
update_post_meta( $order_id, 'my_custom_meta_key', 'my data' );
} , 10, 2);
$order_id
is the id of the order, which is stored as a custom post type$posted
is all the data from$_POST
$order_id
是订单的id,存储为自定义帖子类型$posted
是所有数据来自$_POST
