WooCommerce 电子邮件通知中基于产品类别的不同收件人

Question

我正在为一所销售虚拟产品（费用和远足费用）和物理产品（制服）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，因为它们由不同的部门处理.

例如，所有统一类别的订单都转到收件人一，而所有其他类别的订单都转到收件人二...我遇到过多种方法可以根据产品发送自定义电子邮件，但是这些方法都不符合我的要求。

我还希望能够在不使用 Woocommerce Advanced Notifications 之类的插件的情况下做到这一点。

对此的任何帮助将不胜感激。

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;
}

代码位于活动子主题（或活动主题）的 functions.php 文件中。测试和工作。

笔记：

• 定义的产品类别可以是术语 ID、术语 slug 或术语名称。
• 每个产品类别都需要在相关产品中定义，因为 has_term() WordPress 条件函数不处理父术语。

###Addition 处理父产品类别：

// 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;
}
