我正在使用wp\\u crontrol插件调用函数中添加的操作。php文件，然后调用插件文件中的函数。WP访问了我的函数，但无法调用该类，我遇到以下错误：PHP致命错误：在xxx中找不到类“RSS\\U Import”

我很确定我调用该类的方式不正确，但我不确定在wp\\u cron调用该类之前如何调用该类。

functions.php

add_action( \'my_hookname\', \'my_function_plugin\' );

plugin_file.php

功能。php\'add\\u action（\'my\\u hookname\'，\'my\\u function\\u plugin\'）；\'

plugin\\u文件。php

if ( !defined(\'WP_LOAD_IMPORTERS\') )
return;

// Load Importer API
require_once ABSPATH . \'wp-admin/includes/import.php\';

if ( !class_exists( \'WP_Importer\' ) ) {
 $class_wp_importer = ABSPATH . \'wp-admin/includes/class-wp-importer.php\';
 if ( file_exists( $class_wp_importer ) )
  require_once $class_wp_importer;
}
