wp_notify_postauthor()
云策文档标注
概述
wp_notify_postauthor() 是 WordPress 核心函数,用于在文章有评论、trackback 或 pingback 时,通过电子邮件通知作者或其他指定人员。该函数是可插拔的,允许通过插件或过滤器自定义通知行为。
关键要点
- 函数参数:接受 $comment_id(评论 ID 或 WP_Comment 对象)和已弃用的 $deprecated 参数。
- 返回值:成功时返回 true,若无指定电子邮件地址则返回 false。
- 可插拔性:可通过插件重写此函数,或使用过滤器(如 comment_notification_text、comment_notification_subject、comment_notification_headers)修改邮件内容。
- 通知逻辑:默认仅通知文章作者,但可通过 comment_notification_recipients 过滤器添加其他收件人,并包含多种条件判断(如作者是否通知自己的评论)。
- 邮件内容:根据评论类型(comment、trackback、pingback、note)生成不同的邮件主题和正文,支持本地化切换。
代码示例
// 基本用法示例:通知文章作者有新评论
$comment_id = 123;
$result = wp_notify_postauthor($comment_id);
if ($result) {
echo '通知发送成功';
} else {
echo '通知发送失败或无收件人';
}注意事项
- 函数已弃用 $deprecated 参数,自 3.8.0 版本起不再使用,调用时建议忽略。
- 邮件发送依赖于 wp_mail() 函数,需确保服务器邮件配置正确。
- 通过过滤器自定义时,注意保持邮件格式和编码一致性,避免破坏通知功能。
