最近我开始使用TinyMVC编写了一个简单的菜单模型,我对那些正在使用它或以前使用过的人有几个问题。1. 对于以下代码,我应该将其保留为模型还是插件?2.我应该如何在视图中实现它并在每个需要的页面上使用它而不破坏mvc的想法并且不为每个控制器一次又一次地重写?3. 代码有什么改进吗?4.需要mysql表吗?

代码在这里

<?php
class Menu_Model extends TinyMVC_Model
{
    public function __construct()
    {
        parent::__construct();
    }
    public function listMenu()
    {
        return $this->db->query_all("SELECT * FROM menu_links WHERE is_deleted = 0 ORDER BY position");
    }

    public function listCategorys($menuLinkId)
    {
        return $this->db->query_all("SELECT * FROM menu_subcategorys WHERE menuLinkId = ? AND is_deleted = 0 ORDER BY position", array($menuLinkId));
    }

    public function buildMenu()
    {
        $this->listMenu = $this->listMenu();
        foreach($this->listMenu as $this->listMenuKey => $this->listMenuValue)
        {
            $this->listCategorys = $this->listCategorys($this->listMenuValue['menuLinkId']);
            if(!empty($this->listCategorys))
                $this->listMenu[$this->listMenuKey]['child'] = $this->listCategorys;
        }

        return $this->listMenu;
    }
}
