我有一些预写的对象，可以执行诸如文件检查MIME类型之类的操作，然后是一个主上载对象，但它们都不使用数据库。所以我很好奇是否可以将这些Obejcts集成到Wordpress插件中。

defined( \'ABSPATH\' ) or die( \'No script kiddies please!\' );
add_action(\'admin_menu\', \'file_upload_menu\');
function file_upload_menu()
{
    add_options_page(\'E4K File Uploader\', \'E4k File Uploader\', \'manage_options\', \'e4k-File-Uploader\', \'file_upload_options\');
}
function file_upload_options()
{
    class Example
    {
        public function canI(){ echo \'is this allowed?\'; }
    }
    (new Example)->canI();
}

这样可能吗？我不是Wordpress开发人员，我只是来自开发CMS和API的PHP背景。这对我来说是新的，但我是被要求的，所以我只是好奇Wordpress和/或其插件中OOP的局限性。

Actual Code (Class):

class FileSecure
{
    public $Allowed;
    private $Info;
    public function __construct($allow)
    {
        $this->Allowed = $allow;
        $this->Info    = new finfo();
    }
    public function upload($file, $dir)
    {
        $target = $dir . basename($file["name"]);
        (self::Check($file))? move_uploaded_file($file[\'tmp_name\'], $target) : "";
    }
    public function Check($file)
    {
        if (in_array($fileType = $this->Info->file($file, FILEINFO_MIME_TYPE, $this->Allowed))) { return true; } else { return false; }
    }
}

$fileCheck = array(
    \'Image\' => new FileSecure( [\'image/bmp\', \'image/gif\', \'image/jpeg\', \'image/png\'] ),
    \'Text\' => new FileSecure( [\'text/plain\'] ),
    \'Compressed\' => new FileSecure( [\'application/zip\', \'application/x-rar-compressed\'] )
);

Actual Code (back-end function part):

function file_upload_options()
{
    if (!current_user_can(\'manage_options\'))
    {
        wp_die(__(\'You do not have sufficient permissions to access this page.\'));
    }
    if (isset($_FILES[\'Picture\']))
    {
        require_once \'e4k-file-upload-class.php\';
        if($fileCheck[\'Image\']->upload($_FILES[\'Picture\'], \'Uploads/\')): echo \'<script>alert("Successfully uploaded");</script>\'; endif;
    }
    echo \'<form enctype="multipart/form-data" method="POST">\';
    echo \'<input type="hidden" name="MAX_FILE_SIZE" value="30000" />\';
    echo \'Select a file to upload: <input name="Picture" type="file" />\';
    echo \'<input type="submit" value="Upload File" />\';
    echo \'</form>\';
    echo \'<br /> <br />\';
    echo \'Current Libary: <br /> <br />\';
    foreach(uploaded_files_iterate(\'Upload/\') as $file)
    {
        (is_string($file))? $file : \'<a href="\'.Get_template_directory_uri().\'/Uploads/\'.$file[\'name\'].\'">\'.$file[\'name\'].\'</a> <br />\';
    }
}
