WooCommerce

Question

在 WooCommerce 上，我为每个具有不同（整数）值的产品设置了一个自定义字段 days_manufacture。

我也有这段代码在购物车页面上显示一条消息，最高值为 "days of manufacture":

add_action('woocommerce_before_cart', 'days_of_manufacture');
function days_of_manufacture() {
    $day_txt = ' ' . __('day', 'your_theme_domain_slug' );
    $days_txt = ' ' . __('days', 'your_theme_domain_slug' );
    $text = __('Your Order will be produced in: ', 'your_theme_domain_slug' );
    $max_days = 0;

    foreach( WC()->cart->get_cart() as $cart_item )
        if($cart_item['days_manufacture'] > $max_days)
            $max_days = $cart_item['days_manufacture'];

    if($max_days != 0) {
        if ($max_days == 1)
            $days_txt = $day_txt;

        $output = $text . $max_days . $days_txt;
        echo "<div class='woocommerce-info'>$output</div>";
    }
}

现在我想在 thankyou 查看订单页面和 My account > Orders > View order 页面中显示此消息.

可能吗？

谢谢！

Answer 1

是的……但是由于在相应的模板上没有可用的挂钩，您将不得不覆盖 2 个模板（为此请阅读 how to override woocommerce templates via a theme）。

第 1 步 - 函数

function days_of_manufacture_order_view($order) {
        $day_txt = ' ' . __('day', 'your_theme_domain_slug' );
        $days_txt = ' ' . __('days', 'your_theme_domain_slug' );
        $text = __('Your Order will be produced in: ', 'your_theme_domain_slug' );
        $max_days = 0;

        foreach( $order->get_items() as $item )
            if(get_post_meta($item['product_id'], 'days_manufacture', true) > $max_days )
                $max_days = get_post_meta($item['product_id'], 'days_manufacture', true);

        if($max_days != 0) {
            if ($max_days == 1)
                $days_txt = $day_txt;

            $output = $text . $max_days . $days_txt;
            echo "<div class='woocommerce-info' style='display:block !important;'>$output</div>"; // forcing display for some themes
        }
}

此代码位于您的活动子主题（或主题）的 function.php 文件中或任何插件文件中。

步骤 2 - 在模板中插入函数

1) 我的账户视图订单模板：

此模板位于 your_theme/woocommerce/myaccount/view-order.php

这是该模板的摘录（其中包含函数）：

<?php
/**
 * View Order
 *
 * Shows the details of a particular order on the account page.
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/myaccount/view-order.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see     https://docs.woocommerce.com/document/template-structure/
 * @author  WooThemes
 * @package WooCommerce/Templates
 * @version 2.6.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

?>
<?php days_of_manufacture_order_view($order); // <== inserted Here ?>
<p><?php

// … … …

2) Thankyou 查看订单模板：

此模板位于your_theme/woocommerce/checkout/thankyou.php

这是该模板的摘录（其中包含函数）：

<?php
/**
 * Thankyou page
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/checkout/thankyou.php.
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
 *
 * @see         https://docs.woocommerce.com/document/template-structure/
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.2.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}
if ( $order ) : ?>

<?php days_of_manufacture_order_view($order); // inserted Here ?>

    <?php if ( $order->has_status( 'failed' ) ) : ?>

此代码已经过测试并且可以正常工作
