Php Woocommerce电子邮件通知收件人有条件地基于自定义字段

我有一个带有自定义字段的结账表单

我想根据自定义字段中的值向订单电子邮件添加一个额外的收件人。自定义字段当前是一个下拉菜单，只有3个选项

下面是我能够通过谷歌搜索拼凑出的代码，但这似乎不起作用

function sv_conditional_email_recipient( $recipient, $order ) {

    $custom_field = get_post_meta($orderid, 'custom_field', true);

    if ($custom_field == "Value 1") 
    {
        $recipient .= ', email1@gmail.com';
    } 
    elseif ($custom_field == "Value 2") 
    {
        $recipient .= ', email2@gmail.com';
    }
    elseif ($custom_field == "Value 3") 
    {
        $recipient .= ', email3@gmail.com';
    }
    return $recipient;
}

add_filter( 'woocommerce_email_recipient_new_order', 'sv_conditional_email_recipient', 10, 2 );

感谢您的帮助

$orderid

。请尝试以下方法：

add_filter( 'woocommerce_email_recipient_new_order', 'new_order_conditional_email_recipient', 10, 2 );
function new_order_conditional_email_recipient( $recipient, $order ) {
    if ( ! is_a( $order, 'WC_Order' ) ) return $recipient; // (Optional)

    // Get the order ID (retro compatible)
    $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;

    // Get the custom field value (with the right $order_id)
    $custom_field = get_post_meta( $order_id, 'custom_field', true );

    if ($custom_field == "Value 1") 
        $recipient .= ', email1@gmail.com'; 
    elseif ($custom_field == "Value 2") 
        $recipient .= ', email2@gmail.com';
    elseif ($custom_field == "Value 3") 
        $recipient .= ', email3@gmail.com';

    return $recipient;
}

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

代码经过测试并在WooCommerce 2.6.x和3+上运行

此挂钩仅针对“新订单”电子邮件通知
