Getting order data after successful checkout hook
提问by Syed Haris Ali Ghaznavi
In WooCommerce, I would like to send a request to an API once the customer has successfully checked out. Its basically a website where the client is selling online courses (Like udemy).
在 WooCommerce 中，一旦客户成功结帐，我想向 API 发送请求。它基本上是一个客户销售在线课程的网站（如udemy）。
When the customer checks out, I would like to send an API request and enroll the user for that particular course. I have tried several WooCommerce hooks but none worked for me.
当客户结账时，我想发送一个 API 请求并为该特定课程注册用户。我尝试了几个 WooCommerce 挂钩，但没有一个对我有用。
This is the code that I'm using:
这是我正在使用的代码：
add_action('woocommerce_checkout_order_processed', 'enroll_student', 10, 1);
function enroll_student($order_id)
{
echo $order_id;
echo "Hooked";
}
I am writing this code inside an activated plugin and for ease, I am currently using Cash on Delivery method.
我正在一个激活的插件中编写此代码，为方便起见，我目前使用的是货到付款方法。
Can anyone point me out where I am going wrong because when I checkout I cant see the message "hooked" that I am printing nor the $order_id?
任何人都可以指出我哪里出错了，因为当我结帐时，我看不到我正在打印的“钩住”消息，也看不到$order_id?
It takes me to the success page and doesn't show these two things that I am printing.
它带我到成功页面，并没有显示我正在打印的这两件事。

Update 2Only For Woocommerce 3+ (added restriction to execute the code only once)
更新 2仅适用于 Woocommerce 3+ （添加了仅执行一次代码的限制）
add_action('woocommerce_thankyou', 'enroll_student', 10, 1);
function enroll_student( $order_id ) {
if ( ! $order_id )
return;
// Allow code execution only once
if( ! get_post_meta( $order_id, '_thankyou_action_done', true ) ) {
// Get an instance of the WC_Order object
$order = wc_get_order( $order_id );
// Get the order key
$order_key = $order->get_order_key();
// Get the order number
$order_key = $order->get_order_number();
if($order->is_paid())
$paid = __('yes');
else
$paid = __('no');
// Loop through order items
foreach ( $order->get_items() as $item_id => $item ) {
// Get the product object
$product = $item->get_product();
// Get the product Id
$product_id = $product->get_id();
// Get the product name
$product_id = $item->get_name();
}
// Output some data
echo '<p>Order ID: '. $order_id . ' — Order Status: ' . $order->get_status() . ' — Order is paid: ' . $paid . '</p>';
// Flag the action as done (to avoid repetitions on reload for example)
$order->update_meta_data( '_thankyou_action_done', true );
$order->save();
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
代码位于活动子主题（或主题）的 function.php 文件或任何插件文件中。

May be you could use woocommerce_thankyouhook instead, that will display on order-received page your echoed code, this way:
也许你可以使用woocommerce_thankyou钩子代替，它会在订单接收页面上显示你的回显代码，这样：
add_action('woocommerce_thankyou', 'enroll_student', 10, 1);
function enroll_student( $order_id ) {
if ( ! $order_id )
return;
// Getting an instance of the order object
$order = wc_get_order( $order_id );
if($order->is_paid())
$paid = 'yes';
else
$paid = 'no';
// iterating through each order items (getting product ID and the product object)
// (work for simple and variable products)
foreach ( $order->get_items() as $item_id => $item ) {
if( $item['variation_id'] > 0 ){
$product_id = $item['variation_id']; // variable product
} else {
$product_id = $item['product_id']; // simple product
}
// Get the product object
$product = wc_get_product( $product_id );
}
// Ouptput some data
echo '<p>Order ID: '. $order_id . ' — Order Status: ' . $order->get_status() . ' — Order is paid: ' . $paid . '</p>';
}

WC_Abstract_Ordermethods on the$orderobject.
然后您可以
WC_Abstract_Order在$order对象上使用所有类方法。
