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

<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：

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
