如何在 woocommerce_email_headers 钩子中获取订单 ID

How to get order ID in woocommerce_email_headers hook

我正在尝试在有新订单时设置电子邮件地址。我将 new email 存储在 wp_postmeta 中。

如何在使用woocommerce_email_headers时得到$order_id

我需要获取 order_id 才能将其与 get_post_meta() 函数一起使用。

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('eee@hotmail.com', $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);

如何取回数据?

谢谢。

在 WooCommerce 2.3 及更高版本中,他们更改了传递给过滤器的参数数量

function techie_custom_wooemail_headers( $headers, $id, $object) {

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

    // Replace the emails below to your desire email
    $emails = array('eee@hotmail.com', $email);


    switch($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);

$object - 表示此电子邮件是针对客户、产品或电子邮件的。

尝试 var_dump($object); exit; 内部过滤器回调。

Updated: Added compatibility with Woocommerce version 3+

我做了一些测试试图从 $order object 输出原始数据但没有成功。经过一些其他测试后,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以确保。用你自己的邮箱替换 $your_email 的值。然后您将收到一封电子邮件,其中包含 header 名称中的订单 ID:

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 = '<name@email.com>';
    $headers = "To: Order Num $order_id $your_email";
    return $headers;
}
add_filter( 'woocommerce_email_headers', 'testing_hook_headers', 10, 3);

这是您的代码:

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('eee@hotmail.com', $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,因为它很特别,但你有正确的方式来获取订单 ID。
