Woocommerce 电子邮件通知收件人有条件地基于自定义字段

Question

我有一个带有自定义字段的结帐表单。

我想根据自定义字段中的值向订单电子邮件添加额外的收件人。自定义字段目前是一个只有 3 个选项的下拉菜单。

下面是我通过谷歌搜索拼凑起来的代码，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 );

感谢任何帮助。

谢谢。

您的问题来自未定义的 $orderid。试试这个：

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;
}

代码进入您的活动子主题（或主题）的 function.php 文件或任何插件文件。

代码已经过测试并适用于 WooCommerce 2。6.x 和 3+。
