<?php
namespace appindexmodel;

//导入模型类
use thinkmodel;

class Staff extends model {

//在子类重写父类的初始化方法initialize()
protected function initialize(){
	
  //继承父类中的initialize()
	parent::initialize();
    
  //初始化数据表名称，通常自动获取不需设置
   $this->table = 'tp5_staff'; 

   //初始化数据表字段信息	
   $this->field = $this->db()->getTableInfo('', 'fields');  

   //初始化数据表字段类型
   $this->type = $this->db()->getTableInfo('', 'type'); 

   //初始化数据表主键
   $this->pk = $this->db()->getTableInfo('', 'pk');     
    
	
	}
