基于 WooCommerce 电子邮件通知中的产品类别的不同收件人

Question

我正在为一所同时销售虚拟产品（费用和短途旅行费用）和物理产品（校服）的学校建立一个网站，但是他们希望将每个类别的订单通知发送给不同的收件人由不同部门处理。

例如，所有统一类别的订单都发送给收件人一，而所有其他订单都发送给收件人二...我遇到过多种发送基于产品的自定义电子邮件消息的方法，但是 none 符合我的要求。

我也希望能够在不使用 Woocommerce Advanced Notifications 等插件的情况下执行此操作。

如有任何帮助，我们将不胜感激。

以下将根据您的产品类别向“新订单”电子邮件通知添加其他收件人，您将在带有电子邮件收件人/产品类别对的索引数组中定义这些收件人：

add_filter( 'woocommerce_email_recipient_new_order', 'custom_email_recipient_new_order', 10, 2 );
function custom_email_recipient_new_order( $recipient, $order ) {
    // Not in backend when using $order (avoiding an error)
    if( ! is_a($order, 'WC_Order') ) return $recipient;

    // Define the email recipients / categories pairs in the array
    $recipients_categories = array(
        'email.one@email.com'   => 'category-one',
        'email.two@email.com'   => 'category-two',
        'email.three@email.com' => 'category-three',
    );

    // Loop through order items
    foreach ( $order->get_items() as $item ) {
        // Loop through defined product categories
        foreach ( $recipients_categories as $email => $category ) {
            if( has_term( $category, 'product_cat', $item->get_product_id() ) && strpos($recipient, $email) === false ) {
                $recipient .= ',' . $email;
            }
        }
    }
    return $recipient;
}

Notes:

• The defined Product categories can be term Ids, term slugs or term names.
• Each product category need to be defined in the related products as has_term() WordPress conditional function doesn't handle parent terms.

###处理父产品类别的补充：

// Custom conditional function that handle parent product categories too
function has_product_categories( $categories, $product_id = 0 ) {
    $parent_term_ids = $categories_ids = array(); // Initializing
    $taxonomy        = 'product_cat';
    $product_id      = $product_id == 0 ? get_the_id() : $product_id;

    if( is_string( $categories ) ) {
        $categories = (array) $categories; // Convert string to array
    }

    // Convert categories term names and slugs to categories term ids
    foreach ( $categories as $category ){
        $result = (array) term_exists( $category, $taxonomy );
        if ( ! empty( $result ) ) {
            $categories_ids[] = reset($result);
        }
    }

    // Loop through the current product category terms to get only parent main category term
    foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
        if( $term->parent > 0 ){
            $parent_term_ids[] = $term->parent; // Set the parent product category
            $parent_term_ids[] = $term->term_id; // (and the child)
        } else {
            $parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
        }
    }
    return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}

// Adding custom recipients based on product categories
add_filter( 'woocommerce_email_recipient_new_order', 'custom_email_recipient_new_order', 10, 2 );
function custom_email_recipient_new_order( $recipient, $order ) {
    // Not in backend when using $order (avoiding an error)
    if( ! is_a($order, 'WC_Order') ) return $recipient;

    // Define the email recipients / categories pairs in the array
    $recipients_categories = array(
        'email.one@email.com'   => 'category-one',
        'email.two@email.com'   => 'category-two',
        'email.three@email.com' => 'category-three',
    );

    // Loop through order items
    foreach ( $order->get_items() as $item ) {
        // Loop through defined product categories
        foreach ( $recipients_categories as $email => $category ) {
            if( has_product_categories( $item->get_product_id(), array( $category ) ) && strpos($recipient, $email) === false ) {
                $recipient .= ',' . $email;
            }
        }
    }
    return $recipient;
}
