這篇文章主要介紹了php+ajax發起流程和審核流程（以請假為例） ,需要的朋友可以參考下
上一篇隨筆中已經提到如何新建流程，那麼現在我們就來看看如何發起一個流程和審核流程~~~
先說一下想法：
##（1）登入用session取得到使用者的id (2) 使用者啟動一個流程 ：需要寫申請事由#（3）節點的審核者去依序審核# 註：每審核通過一個，對應towhere欄位要加1；審核到最後時，對應的isok欄位要變成1（此處1表示結束，0表示未結束）共用到三張表：
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <form method="post" action="denglu-cl.php"> 用户名：<input type="text" name="uid" /><br /> 密码：<input type="password" name="pwd" /><br /> <input type="submit" value="登录" /> </form> </body> </html>
<?php
session_start();
require "../DB.class.php";
$db = new DB();
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
$sql = "select pwd from users where uid='{$uid}'";
$mm = $db->strquery($sql);
if($pwd==$mm && !empty($pwd))
{
$_SESSION["uid"]=$uid;
header("location:liucheng.php");
}
else
{
echo "密码或登录名输入错误";
}
?>
