本文實例為大家分享了ajax和PHP實現簡單的流程管理，供大家參考，具體內容如下
首先要先有一個新建流程的頁面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>
請選擇節點人員：
<select id="user">
<?php
session_start();//需要將一些數據暫時存在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]}'>{$v[2]}</option>";
}
?>
</select>
<input type="button" value="添加節點" id="add" />
</div>
<br />
<div>
<?php
if(!empty($_SESSION["user"]))
{
$attr = $_SESSION["user"];
foreach($attr as $k=>$v) //索引為$k,取值為$v
{
$sname = "select name from users where uid='{$v}'"; //取出名稱
$name = $db->StrQuery($sname);
echo "<div>{$k}--{$name}--<input type='button' value='刪除' key='{$k}' class='del' /></div>"; //向處理頁面傳的是key的值
}
}
?>
</div>
<br />
<div>請輸入流程名稱：<input type="text" id="name" /></div>
<br />
<input type="button" value="保存" id="btn" />
</body>
<script type="text/javascript">
//添加節點按鈕加點擊
$("#add").click(function(){
var uid = $("#user").val();
$.ajax({
url:"chuli.php",
data:{uid:uid,type:0}, //傳入一個type參數，以確保在同一頁面處理時與其它的分開處理
type:"POST",
dataType:"TEXT",
success: function(data){
window.location.href="xinjian.php" rel="external nofollow" rel="external nofollow" ; //刷新頁面
}
});
})
//給刪除按鈕加點擊
$(".del").click(function(){
var key = $(this).attr("key"); //取刪除的是哪條數據
$.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" ;
}
});
})
//給保存按鈕加點擊
$("#btn").click(function(){
var name = $("#name").val(); //取輸入框中輸入內容的值
$.ajax({
url:"chuli.php",
data:{name:name,type:2},
type:"POST",
dataType:"TEXT",
success:function(data){
alert("保存成功！");
}
});
})
</script>
</html>
數據庫圖片:
處理頁面chuli.php
<?php
session_start();
include("../FENGZHUANG/DBDA.class.php");
$db = new DBDA();
$type = $_POST["type"];
switch($type)
{
case 0://添加節點的加載數據,向session數組中添加數據
$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://取節點的索引，然后刪除，重新索引
$key = $_POST["key"];
$arr = $_SESSION["user"];
unset($arr[$key]); //刪除
$arr = array_values($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);
//添加流程節點
$arr = $_SESSION["user"];
foreach($arr as $k=>$v)
{
$sql = "insert into flowpath values('','{$code}','{$v}','{$k}')";
$db->Query($sql,0);
}
break;
case 3: //用戶發起流程
$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;
}
發起流程頁面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">

<script src="../FENGZHUANG/jquery-3.1.1.min.js"></script>
</head>
<body>
<h1>發起流程</h1>
<div>
請選擇發起的流程：
<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>
請輸入內容：
<textarea id="nr"></textarea>
</div>
<br />
<input type="button" value="發起" 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("發起成功！");
}
});
