时间：2017-04-08

本文实例为大家分享了ajax和PHP实现简单的流程管理，供大家参考，具体内容如下

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" rel="external nofollow" rel="external nofollow" ; //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" rel="external nofollow" rel="external nofollow" ;
    }
   });
 })
//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);
  break;
  
}

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">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>发起流程</title><br />
<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({
   url:"chuli.php",
   data:{code:code,content:content,type:3},
   type:"POST",
   dataType:"TEXT",
   success: function(data){
    alert("发起成功！");
    }   
   });
 })
</script>
</html>
