PHP+Mysql+jQuery+fullcalendar实现的微型公司内部订餐系统

本文涉及到的插件: jQuery, jQuery.UI, fullcalendar

数据库教程创建:

CREATE TABLE USER
(
  ID INT PRIMARY KEY AUTO_INCREMENT,
  NAME VARCHAR(100)
);

CREATE TABLE ITEM
(
  ID INT PRIMARY KEY AUTO_INCREMENT,
  USER_ID INT,
  FOOD TINYBOLB,
  ORDER_TIME TIMESTAMP
);

ALTER TABLE ITEM ADD FOREIGN KEY(USER_ID) REFERENCES USER(ID) ON DELETE CASCADE;

一个实体的基类, 封装的不太好: Entity.php教程

PHP code

用户类(这个里面是没有权限, 登录的概念的, 就公司内部一个小东西): User.php

PHP code
require_once './Entity.php';

/**
 * 用户实体类
 * @author selfimpr
 * @blog http://blog.111com.net/lgg201
 * @email [email protected]
 *
 */
class User extends Entity {
    private $id;
    private $name;
   
    public function User($id = NULL, $name = NULL) {
        $this->id = $id;
        $this->name = $name;
    }
   
    public function getId() {
        return $this->id;
    }
    public function setId($id) {
        $this->id = $id;
        return $this;
    }
    public function getName() {
        return $this->name;
    }
    public function setName($name) {
        $this->name = $name;
        return $this;
    }
}
?>

订餐订单项类: Item.php

PHP code
require_once './Entity.php';
/**

 * @author selfimpr
 * @blog http://blog.111com.net/lgg201
 * @email [email protected]

    private $id;
    private $user;
    private $food;
    private $orderTime;
   
    public function Item($id = NULL, $food = NULL, $orderTime = NULL) {
        $this->id = $id;
        $this->food = $food;
        $this->orderTime = $orderTime;
    }
   
    public function getId() {
        return $this->id;
    }
    public function setId($id) {
        $this->id = $id;
        return $this;
    }
    public function getUser() {
        return $this->user;
    }
    public function setUser($user) {
        $this->user = $user;
        return $this;
    }
    public function getFood() {
        return $this->food;
    }
    public function setFood($food) {
        $this->food = $food;
        return $this;
    }
    public function getOrderTime() {
        return $this->orderTime;
    }
    public function setOrderTime($orderTime) {
        $this->orderTime = $orderTime;
        return $this;
    }
