wordpress woocommerce interfax发送缺少字段的传真

Question

我不是一个php程序员，我需要永远弄明白为什么。所以希望SO可以帮助我。基本上，我安装了一个名为interfax-woocommerce的woocommerce插件，用于将订单完成电子邮件发送到传真号码。在文档中，它说该插件使用订单完成模板来发送传真。除了保留订单备注字段外，它确实包含订单电子邮件模板中的所有内容。我相信它必须与插件有关。也许它通过订单数组而不包括那个特定的订单备注字段？我无法弄清楚为什么以及如何解决它。以下是interfax插件的源代码

Answer 1

以下是将客户备注（即订单帖子的“摘录”）添加到所有电子邮件底部的示例：

add_action( 'woocommerce_email_after_order_table' , 'so_28333042_add_customer_note' );
function so_28333042_add_customer_note( $order ){
    $post = get_post( $order->id );
    if( $post->post_excerpt != '' ){
        echo "<strong>Customer Note:</strong><br/>" . wp_kses_post( $post->post_excerpt );
    }
}

woocommerce_email_after_order_table挂钩绝对可以在WooCommerce 2.3中使用，但我认为它也可以在2.2+中使用。

或者，您可以将customer-completed-order.php模板复制到主题中并直接在其上工作。
