篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了php实现简单的流程管理相关的知识,希望对你有一定的参考价值。
流程管理,在各种系统中扮演很重要的地位,可以把设定好的流程放入系统中,规定好几个节点,只要所有节点都通过,就可以通过。
惯例,先看数据库:
我们首先做一个新建流程页面,先把节点做好
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>无标题文档</title> <script src="../dist/js/jquery-1.11.2.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(); include("../fengzhuang/DBDA.class.php"); $db = new DBDA(); $sql = "select * from lc_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) { $sname = "select name from lc_users where uid=\'{$v}\'"; $name = $db->StrQuery($sname); echo "<div>{$k}--{$name}--<input type=\'button\' value=\'删除\' key=\'{$k}\' class=\'del\' /></div>"; } } ?> </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}, type:"POST", dataType:"TEXT", success: function(data){ window.location.href="xinjian.php"; } }); }) //给删除按钮加点击 $(".del").click(function(){ var key = $(this).attr("key"); $.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(); $.ajax({ url:"chuli.php", data:{name:name,type:2}, type:"POST", dataType:"TEXT", success:function(data){ alert("保存成功!"); } }); }) </script> </html>
chuli.php
<?php session_start(); include("../fengzhuang/DBDA.class.php"); $db = new DBDA(); $type = $_POST["type"]; switch($type) { case 0: $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: $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 $sql = "insert into lc_liucheng values(\'{$code}\',\'{$name}\')"; $db->Query($sql,0); //添加流程节点 $arr = $_SESSION["user"]; foreach($arr as $k=>$v) { $sql = "insert into lc_flowpath values(\'\',\'{$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"); $sql = "insert into lc_userflow values(\'\',\'{$code}\',\'{$uid}\',\'{$nr}\',0,\'{$time}\',0)"; $db->Query($sql,0); break; }
完成的效果,如图:
点击选择节点人员可以从数据库调所有人员名单,现在把李四,马七和张三放入流程中,做一个请假流程:
点击保存,存到数据库:
注意:Code必须用varchar,不能用time,因为在上面用了时间戳
现在我们在做一个登陆用户,提交请假流程的所有步骤:
weilogin.php 一个伪账户

张三发个请假流程,
李四的页面:
点击通过后
数据库:towhere变成1了
接着该马七:
然后是张三:
数据库:isok变成1了
