关于WordPress文件及其使用方法的综合指南
_wp_customize_include ( No parameters )
_wp_customize_include: 这个函数包括WordPress定制器的必要文件。定制器是一个工具,允许用户实时定制他们网站的外观和设置。
包含并实例化WP_Customize_Manager类。
当访问customize.php管理页面或任何请求包括wp_customize=on参数或customize_changeset参数(UUID)时,会在plugins_loaded加载自定义器。这个参数是一个信号,当WordPress正在加载时,特别是在Customizer预览或为小工具或菜单做Customizer Ajax请求时,是否启动Customizer。
