用php+ajax新建流程（请假、进货、出货等）

<?php
session_start();
require "../DB.class.php";
$db = new DB();
//将数据写进liucheng表
$name = $_POST["name"];
$code=time();//用时间戳来生成code
$sql = "insert into liucheng values('{$code}','{$name}')";
$db->query($sql,0);
//将数据写入liucehngjiedian表
$arr = $_SESSION["jiedian"];
foreach($arr as $k=>$v)
{
 $sql = "insert into liuchengjiedian values ('','{$code}','{$v}','{$k}')";
 $db->query($sql,0);
}
?>
