php如何实现流程管理？

php实现流程管理的方法：首先新建流程页面，并建好节点；然后点击选择节点人员可以从数据库调所有人员名单；最后做一个登陆用户，提交请假流程的所有步骤即可。

php实现流程管理的方法：

我们首先做一个新建流程页面，先把节点做好

<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：

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
