Question

我正在使用WP 4.9.9 + WC 3.5.1。

我尝试将图像文件附加到电子邮件。这是创建订单后发送的电子邮件。在订单中显示名为 ac_order_customer_image 的字段（使用ACF插件创建）。

在我的 function.php 文件中，显示以下代码：

add_filter( 'woocommerce_email_attachments', 'woocommerce_emails_attach_ac_order_customer_image', 10, 3);

function woocommerce_emails_attach_ac_order_customer_image($attachments, $status, $order) {
    error_log('woocommerce_emails_attach_ac_order_customer_image START');
    if ( ! is_object( $order ) || ! isset( $status ) ) {
        return $attachments;
    }
    error_log('woocommerce_emails_attach_ac_order_customer_image ORDER and STATUS setted');
    if ( empty( $order ) ) {
        return $attachments;
    }
    error_log('woocommerce_emails_attach_ac_order_customer_image ORDER not empty');
    $image = get_field('ac_order_customer_image', $order->ID);
    error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE: ' . serialize($image));
    if ( ! $image ) {
        return $attachments;
    }
    error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE is setted ');
    if (is_array($image)){
        error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE is ARRAY. Add URL from ARRAY ');
        $attachments[] = $image['url'];
    }
    if (is_int($image)){
        error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE is INT. Get URL and ADD ');
        $url = wp_get_attachment_image_src($image);
        if (is_array($url)){
            error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE(ret arr): ' . serialize($url[0]));
            $attachments[] = $url[0];
        }
        if (is_string($url)){
            error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE: ' . $url);
            $attachments[] = $url;
        }
    }
    if (is_string($image)){
        error_log('woocommerce_emails_attach_ac_order_customer_image IMAGE is STRING. Add URL string ');
        $attachments[] = $image;
    }
    error_log('woocommerce_emails_attach_ac_order_customer_image FINISH ');
    return $attachments;

}

我收到电子邮件，但没有附件。我在做什么错了？

woocommerce_email_attachments不起作用？
