php+ajax发起流程和审核流程（以请假为例）

<?php
$ids = $_GET["code"];
require "../DB.class.php";
$db = new DB();
//点击审核后，towhere列加1，目的是使流程向下走
$sql = "update liuchengpath set towhere = towhere+1 where ids ='{$ids}' ";
$db->query($sql,0);
//当流程走到最后一个审核的人时，流程要结束
//获取该流程最大的orders
$sql =" select max(orders) from liuchengjiedian where code = (select code from liuchengpath where ids ='{$ids}')";
$maxorders = $db->strquery($sql);
//获取该用户处于哪个位置，也就是towhere等于多少
$sql ="select towhere from liuchengpath where ids ='{$ids}'";
$towhere = $db->strquery($sql);
//判断是否已到达最后一个审核的人
if($towhere>$maxorders)
{
 $sql = "update liuchengpath set isok=1 where ids='{$ids}'";
// var_dump($sql);
 $db->query($sql,0);
}
header("location:shenhe.php");
