概述

update_feedback 是一个 WordPress 核心更新过程中用于过滤反馈消息的过滤器。它在核心升级的不同阶段被调用，允许开发者自定义显示给用户的更新状态信息。

关键要点

  • update_feedback 过滤器在核心更新流程中多次触发，包括下载解压后、升级开始前、维护模式启用前后、文件复制前和数据库升级前。
  • 参数 $feedback 是一个字符串，代表当前的更新反馈消息，开发者可以修改此消息以提供更定制化的用户体验。
  • 该过滤器在 WordPress 2.5.0 版本中引入，常用于 Core_Upgrader::upgrade() 和 update_core() 函数中。

代码示例

apply_filters( 'update_feedback', __( 'Verifying the unpacked files…' ) );
