[PC]PHPCMS二次开发指南（上），phpcms二次开发

-------------------------------------------------------------------------------------

PHPCMS本身功能已经很完善，自带的模块可用可不用，松耦合特性使其非常适合企业的二次开发。

PC的默认路由在 phpcms/caches/configs/route.php 中定义，为content模块下index控制器的init方法

 

一. PC所有模块都在module目录下，与数据表名字相同；

　　module目录中文件就是控制器，控制器名与文件名相同；

　　前台控制器如index.php无须继承任何类，用于前台操作；

　　后台控制器一般需要继承admin模块的admin类，一旦继承admin就需要权限验证（也可以不继承）。

 

二. 总结开发后台模块的步骤：

　　1. 后台访问扩展的模块：

　　　　扩展 - 菜单管理 - 添加菜单 - 上级：作为一级菜单（模块名，文件名，方法名）

　　　　　　　　　　　　添加子菜单 - 上级：某个一级菜单（填不存在的模块名，填不存在的文件名，填不存在的方法名）

　　　　扩展模块后，需要在v9_module中注册模块！（相当于安装）

　　

　　2. 创建数据表：

<span>create</span> <span>table</span><span> v9_link(
    .........</span><span>
)engine</span><span>=</span>myisam <span>default</span> charset<span>=</span><span>'</span><span>utf8</span><span>'</span><span>;</span><span><br /></span>
Nach dem Login kopieren

　　

　　3. 建立后台的数据模型

<?<span>php<br /></span><span>defined</span>('IN_PHPCMS') or <span>exit</span>('No permiss resources.'<span>);
pc_base</span>::load_sys_class('model', '', 0<span>);
</span><span>class</span> link_model <span>extends</span><span> model {
    </span><span>function</span><span> __construct() {
        </span><span>$this</span>->db_config = pc_base::load_config('database'<span>);
        </span><span>$htis</span>->db_setting = 'default'<span>;
        </span><span>$this</span>->table_name = 'link'<span>;
        parent</span>::<span>__construct();
    }    
}

</span><span>/*</span><span>*
 * 几点注意：
 * 1. PC的数据模型基本是鸡肋，只是指定了数据库设置和对应的表名，非彻底的MVC，直接复制一份修改即可。
 * 2. 此模型一般在控制器构造方法调用。<br /> </span><span>*/</span>
