首先要先有一个新建流程的页面xinjian.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>新建</title>
<script src="../FENGZHUANG/jquery-3.1.1.min.js"></script>
</head>
<body>
<h1>新建流程</h1>
<div>
请选择节点人员：
<select id="user">
<?php
session_start();//需要将一些数据暂时存在session里
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();
$sql = "select * from users";
$arr = $db->Query($sql);
foreach($arr as $v)
{
echo "<option value=\'{$v[0]}\'>{$v[2]}</option>";
}
?>
</select>
<input type="button" value="添加节点" id="add" />
</div>
<br />
<div>
<?php
if(!empty($_SESSION["user"]))
{
$attr = $_SESSION["user"];
foreach($attr as $k=>$v) //索引为$k,取值为$v
{
$sname = "select name from users where uid=\'{$v}\'"; //取出名称
$name = $db->StrQuery($sname);
echo "<div>{$k}--{$name}--<input type=\'button\' value=\'删除\' key=\'{$k}\' class=\'del\' /></div>"; //向处理页面传的是key的值
}
}
?>
</div>
<br />
<div>请输入流程名称：<input type="text" id="name" /></div>
<br />
<input type="button" value="保存" id="btn" />
</body>
<script type="text/javascript">
//添加节点按钮加点击
$("#add").click(function(){
var uid = $("#user").val();
$.ajax({
url:"chuli.php",
data:{uid:uid,type:0}, //传入一个type参数，以确保在同一页面处理时与其它的分开处理
type:"POST",
dataType:"TEXT",
success: function(data){
window.location.href="xinjian.php"; //刷新页面
}
});
})
//给删除按钮加点击
$(".del").click(function(){
var key = $(this).attr("key"); //取删除的是哪条数据
$.ajax({
url:"chuli.php",
data:{key:key,type:1},
type:"POST",
dataType:"TEXT",
success:function(data){
window.location.href="xinjian.php";
}
});
})
//给保存按钮加点击
$("#btn").click(function(){
var name = $("#name").val(); //取输入框中输入内容的值
$.ajax({
url:"chuli.php",
data:{name:name,type:2},
type:"POST",
dataType:"TEXT",
success:function(data){
alert("保存成功！");
}
});
})
</script>
</html>

处理页面chuli.php
<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();
$type = $_POST["type"];
switch($type)
{
case 0://添加节点的加载数据,向session数组中添加数据
$uid = $_POST["uid"];
if(empty($_SESSION["user"]))
{
$arr = array($uid);
$_SESSION["user"] = $arr;
}
else
{
$arr = $_SESSION["user"];
array_push($arr,$uid);
$_SESSION["user"] = $arr;
}
break;
case 1://取节点的索引，然后删除，重新索引
$key = $_POST["key"];
$arr = $_SESSION["user"];
unset($arr[$key]); //删除
$arr = array_values($arr); //重新索引
$_SESSION["user"] = $arr;
break;
case 2:
$name = $_POST["name"];
$code = time();
//添加流程
$sql = "insert into liucheng values(\'{$code}\',\'{$name}\')";
$db->Query($sql,0);
//添加流程节点
$arr = $_SESSION["user"];
foreach($arr as $k=>$v)
{
$sql = "insert into flowpath values(\'\',\'{$code}\',\'{$v}\',\'{$k}\')";
$db->Query($sql,0);
}
break;
case 3: //用户发起流程
$code = $_POST["code"];
$nr = $_POST["content"];
$uid = $_SESSION["uid"];
$time = date("Y-m-d H:i:s");
$sql = "insert into userflow values(\'\',\'{$code}\',\'{$uid}\',\'{$nr}\',0,\'{$time}\',0)";
$db->Query($sql,0);

发起流程页面faqi.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script src="../FENGZHUANG/jquery-3.1.1.min.js"></script>
</head>
<body>
<h1>发起流程</h1>
<div>
请选择发起的流程：
<select id="liucheng">
<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();
$sql = "select * from liucheng";
$arr = $db->Query($sql);
foreach($arr as $v)
{
echo "<option value=\'{$v[0]}\'>{$v[1]}</option>";
}
?>
</select>
</div>
<br />
<div>
请输入内容：
<textarea id="nr"></textarea>
</div>
<br />
<input type="button" value="发起" id="btn" />
</body>
<script type="text/javascript">
$("#btn").click(function(){
var code = $("#liucheng").val();
var content = $("#nr").val();
$.ajax({
