php – 如何在woocommerce_email_headers钩子中获取订单ID

我正在尝试在新订单时设置电子邮件地址.我将新电子邮件存储在wp_postmeta中.

使用woocommerce_email_headers时如何获得$order_id？

我需要让order_id与get_post_meta()函数一起使用它.

这是我的代码：

function techie_custom_wooemail_headers( $headers, $object) {

    $email = get_post_meta( $order_id, '_approver_email', true );

    // Replace the emails below to your desire email
    $emails = array('[email protected]', $email);


    switch($object) {
        case 'new_order':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;
        case 'customer_processing_order':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;
        case 'customer_completed_order':
        case 'customer_invoice':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;

        default:
    }

    return $headers;
}

add_filter( 'woocommerce_email_headers', 'techie_custom_wooemail_headers', 10, 2);

我如何取回数据？

谢谢.

解决方法:

Updated: Added compatibility with Woocommerce version 3+

我做了一些测试试图从$order对象输出原始数据但没有成功.经过一些其他测试,我现在得到了正确的订单ID.我已经使用下面的代码进行测试.用您自己的电子邮件替换$your_email的值.然后,您将收到标题名称中包含订单ID的电子邮件：

function testing_hook_headers( $headers, $id, $order ) {
    // The order ID | Compatibility with WC version +3
    $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;

    $your_email = '<[email protected]>';
    $headers = "To: Order Num $order_id $your_email";
    return $headers;
}
add_filter( 'woocommerce_email_headers', 'testing_hook_headers', 10, 3);

所以这是你的代码：

function techie_custom_wooemail_headers( $headers, $email_id, $order ) {

    // The order ID | Compatibility with WC version +3
    $order_id = method_exists( $order, 'get_id' ) ? $order->get_id() : $order->id;

    $email = get_post_meta( $order_id, '_approver_email', true );

    // Replace the emails below to your desire email
    $emails = array('[email protected]', $email);

    switch( $email_id ) {
        case 'new_order':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;
        case 'customer_processing_order':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;
        case 'customer_completed_order':
        case 'customer_invoice':
            $headers .= 'Bcc: ' . implode(',', $emails) . "\r\n";
            break;

        default:
    }

    return $headers;
}

add_filter( 'woocommerce_email_headers', 'techie_custom_wooemail_headers', 10, 3);

我没有测试你的代码,因为它是特别的,但你有正确的方式来获得订单ID.
