通过提及功能增强您的WordPress评论

>本教程演示了构建一个WordPress插件，该插件在注释中添加了类似Twitter的@Mention功能。 用户可以互相标记，改善注释互动。

密钥功能：

• @mention功能：插件使用户可以使用“@”符号标记其他评论者，类似于Twitter。
• 电子邮件通知：提到的用户收到有关新评论的电子邮件警报。
• WordPress集成：与WordPress的评论Meneration System无缝集成。
自定义：
• 轻松调整@mention文本颜色和其他设置。

>插件开发：

插件，，位于

>目录中。 插件标头对于WordPress识别至关重要：

wp-mention-plugin.php /wp-content/plugins/核心功能被封装在

>类中：>

挂钩来管理提及和通知。 切记在电子邮件主体中用网站的名称替换

。comment_text> wp_set_comment_statuswp_insert_comment "MyBlog.com"

这个增强的版本直接在评论文本中设计了提及，从而提供了更具用户友好的体验。 为了清楚起见，还改进了电子邮件通知。 请记住要处理生产环境中的潜在错误（例如，找不到电子邮件）。
