PHP+Mysql+jQuery+fullcalendar实现的微型公司内部订餐系统
需求相关: 公司20人左右, 每天中午, 下午两次订餐, 都是助理在群里说"开始订餐", 然后大家报菜名, 然后助理统计, 打电话. 今天, 助理说"开始订餐, 订什么密聊...", 突然就想做这么个东西....
耗时: 4.5小时
评估: 时间太短, 不能做到很好, 没有什么输入验证之类, 就自己公司内部一点人, 用用应该没啥问题.....bug估计很多...应该是没时间改bug的, 不过有不足之处请大家提出, 互相学习.
提醒: 由于我这边和服务器有个时差, 所以, 里面有代码在倒时差.....另外, 13点之前被认为是上午, 之后包括13点被认为是下午, 一天两次.
本文涉及到的插件: jQuery , jQuery.UI , fullcalendar
数据库创建:
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...呵呵
$method($value); } public function get() { $method = 'get'.ucwords($field); return $this->$method(); } } ?>
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)
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
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; } } ?>
数据库工具类
host = $host; $this->username = $username; $this->password = $password; $this->db_name = $db_name; $this->character_set = $character_set; } public function getConn() { $conn = mysql_connect($this->host, $this->username, $this->password) or die('数据库连接失败'); mysql_select_db($this->db_name, $conn); mysql_set_charset($this->character_set, $conn); return $conn; } /** * * @param $sql 查询用的sql * @param $result 查询得到的结果集, 如果UPDATE, INSERT, DELETE 不同提供这个参数 * @return SELECT 返回查询得到的条数, UPDATE, INSERT, DELETE返回bool型, 标识是否执行成功. */ public function execute($sql) { $conn = $this->getConn(); $resultset = mysql_query($sql, $conn) or die(mysql_error($conn)); if(!is_bool($resultset)) { while($line = mysql_fetch_assoc($resultset)) { $result[] = $line; } } else { $result = $resultset; } mysql_close($conn) or die(mysql_error($conn)); // echo "【".$sql."】 excute success!
"; return $result; } } ?>
业务逻辑(没时间了就写一个文件里了)
execute("SELECT * FROM USER"); foreach($users_data as $index => $data) { $user = new User(); foreach($data as $column_name => $value) { $user->set(User::getField($column_name), $value); } $users[] = $user; } return $users; } /** * 根据名字增加一个用户 * @param $name * @return unknown_type */ function addUser($name) { $util = new Mysql(); $name = iconv("UTF-8", "gbk" , $name); return $util->execute("INSERT INTO USER VALUES(NULL, '$name')"); } /** * 根据id删除一个用户 * @param $id * @return unknown_type */ function deleteUser($id) { $util = new Mysql(); return $util->execute("DELETE FROM USER WHERE ID = $id"); } /** * 根据id修改姓名 * @param $id * @param $name * @return unknown_type */ function updateUser($id, $name) { $util = new Mysql(); return $util->execute("UPDATE USER SET NAME = '$name' WHERE ID = $id"); } /** * 插入一条订餐记录 * @param $user_id * @param $food * @return unknown_type */ function addItem($user_id, $food, $ordertime) { $util = new Mysql(); $year = date('Y', $ordertime); $month = date('n', $ordertime); $day = date('j', $ordertime); $hour = (date('G', $ordertime) + 8) % 24; $flag = $hour < 13; $item = getItemByTimeAndUser($year, $month, $day, $flag, $user_id); $ordertime = "$year-$month-$day $hour:00:00"; $item && ($item = $item[0]) && ($flag = $flag ?
