1.3.3 提问:请解释WordPress插件的钩⼦和过滤器是什么?

WordPress插件的钩⼦和过滤器是扩展WordPress功能的重要机制。钩⼦(Hooks)允许开发者在特定时刻执⾏⾃定义代码,包括执⾏前和执⾏后。有两种钩⼦类型:动作钩⼦(Action Hooks)和过滤器钩⼦(Filter Hooks)。动作钩⼦⽤于执⾏特定操作或功能,⽽过滤器钩⼦⽤于修改数据并返回。开发者可通过add_action()和add_filter()函数将⾃定义功能绑定到特定的钩⼦。⽰例:// 动作钩⼦示例function custom_action_function() {// 执⾏⾃定义操作 }// 过滤器钩⼦示例function custom_filter_function($content) {// 修改内容return $content; }
