Php Wordpress上载文件夹子目录

我在Wordpress uploads文件夹中创建了许多子文件夹，并希望根据仪表板中显示的当前页面以编程方式指定文件应上载到哪个文件夹

以下是迄今为止我掌握的代码：

function field_name_upload_prefilter($errors) {
    // in this filter we add a WP filter that alters the upload path
    add_filter('upload_dir', 'field_name_upload_dir');
        return $errors;
}
// Second filter
function field_name_upload_dir($uploads) {
    // here is where we later the path
    if($pagenow == 'archive'){
        $uploads['path'] = $uploads['basedir'].'/archive';
        $uploads['url'] = $uploads['baseurl'].'/archive';
        $uploads['subdir'] = '';
    }

    if ($pagenow = 'assets') {
        $uploads['path'] = $uploads['basedir'].'/assets';
        $uploads['url'] = $uploads['baseurl'].'/assets';
        $uploads['subdir'] = '';
    }

    return $uploads;
}

正常检查，研究那边的钩子名称可以提供很多解决方案。你的新文件夹名称是什么样子的？。它是否与页面slug名称相同？
