Question

如果客户购买了特定产品，如何获取该产品的订单ID？我尝试了下面的代码，但是没有用。感谢您的提前帮助。

const express = require('express');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const passport = require('passport');
const path = require('path');


//Route files
const users = require('./routes/api/users');
const fpsos = require('./routes/api/fpsos');
const bids = require('./routes/api/bids');
const news = require('./routes/api/news');

const app = express();

//Body parser middlewares
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json ());

//DB config
const db = require('./config/keys').mongoURI;
//Connect to MongoDB
mongoose
    .connect(db)
    .then(() => console.log('MongoDB connected'))
    .catch(err => console.log(err));

//Passport middleware
app.use(passport.initialize());

//Passport Config
require('./config/passport')(passport);

app.use('/api/users', users);
app.use('/api/news', news);
app.use('/api/fpso', fpsos);
app.use('/api/bid', bids);


// Server static assets if in production
if (process.env.NODE_ENV === 'production') {
    // Set static folder
    app.use(express.static('client/build'));

    app.get('*', (req, res) => {
        res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'));
    });
}

const port = process.env.PORT || 5000;

app.listen(port, () => console.log(`Server running on port ${port}`))

也尝试过此代码，但是没有用。

<?php
 $order = new wc_get_order( $order_id );
 $order->get_id();
 echo $order->get_order_number();
?>

Answer 1

function get_order_ids_from_bought_items() {

    $prod_arr = array('37', '53');
    $purchased = false;

    $customer_orders = get_posts(array(
        'numberposts' => -1,
        'post_type' => 'shop_order',
        'meta_key' => '_customer_user',
        'meta_value' => get_current_user_id(),
            ));
    foreach ($customer_orders as $order_post) {


        $order = wc_get_order($order_post->ID);

        foreach ($order->get_items() as $item) {

            $product_id = $item->get_product_id();

            if (in_array($product_id, $prod_arr))
                $purchased = true;
        }
    }

    return $purchased; // $order_post->ID  for Order ID
}

以下函数使用非常轻量级的SQL查询，该查询将返回给定客户的已定义产品ID的最后一个订单ID：

function get_last_order_id_from_product( $product_id, $user_id = 0 ) {
    global $wpdb;

    $customer_id = $user_id == 0 ? get_current_user_id() : $user_id;

    return $wpdb->get_var( "
        SELECT p.ID FROM {$wpdb->prefix}posts AS p
        INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_items AS woi ON p.ID = woi.order_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        WHERE p.post_type = 'shop_order'
        AND pm.meta_key = '_customer_user'
        AND pm.meta_value = $customer_id
        AND woim.meta_key IN ( '_product_id', '_variation_id' )
        AND woim.meta_value = $product_id
        ORDER BY p.ID DESC  LIMIT 1
    " );
}

代码在您的活动子主题（或活动主题）的function.php文件上。经过测试，可以正常工作。

如果客户尚未购买产品，该功能将返回 false 。

用法示例：

在下面，您将设置产品ID 37 ，还可以设置用户ID 153 （如果您不要在函数可以获取当前用户ID的前端使用代码* /

$order_id = get_last_order_id_from_product( 37, 153 );

或对于当前用户：

$order_id = get_last_order_id_from_product( 37 );

在Woocommerce中从购买的产品ID获取最后的订单ID
