核心邏輯：流程管理，在各種系統中扮演很重要的地位，可以把設定好的流程放入系統中，規定好幾個節點，只要所有節點都通過，就可以通過。
建立四張資料庫表：
1.我們先做一個新流程頁面 flow.php，先把節點做好
#
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
</head>
<body>
<h2>管理员新建流程</h2>
<p><select id="users" name="users">
<? "./DBDA.class.php" = = "select * from users" = ->query(,0( "<option value='{[0]}'>{[2]}</option>"?>
</select>
<input type="button" value="添加" id="add" />
</p>
<br />
<p>
<?((["jd" "还未添加节点人员!" = ["jd"];
( =>){
= "select name from users where uid='{}'" = ->StrQuery(,0);
"<p>{}--{}--<input type='button' value='删除' class='del' code='{}' /></p>"?>
</p>
<br />
<p><input type="text" id="name" />
</p>
<br />
<input type="button" value="新建" id="addbtn" />
</body>
<script>
"#add").click( uid = $("#users")..:"flowchuli.php",:"POST",:{uid:uid,type:0},:"TEXT",:.location.href = "flow.php"".del").click( k = $(this).attr("code");
$.:"flowchuli.php",:"POST",:{k:k,type:1},:"TEXT",:.location.href = "flow.php"
$("#addbtn").click( name = $("#name")..:"flowchuli.php",:"POST",:{name:name,type:2},:"TEXT",:"添加成功!"</script>
</html>2.做新流程頁面的處理頁面flowchuli.php
<?phpsession_start();require_once "./DBDA.class.php";$db = new DBDA();$type = $_POST["type"];switch($type){ case 0: $uid = $_POST["uid"]; if(empty($_SESSION["jd"])){//暂存节点
$arr = array($uid);//新造数组
$_SESSION["jd"] = $arr;//存入session
}else{ $arr = $_SESSION["jd"];//取数组
$arr[] = $uid;//追加变量到数组
$_SESSION["jd"] = $arr;
} break; case 1: $k = $_POST["k"]; $arr = $_SESSION["jd"]; unset($arr[$k]); $arr = array_values($arr);//重新对数组进行排序，有返回值接收
$_SESSION["jd"] = $arr; break; case 2:
$name = $_POST["name"]; $code = time();//自动生成
$sql = "insert into flow values('{$code}','{$name}')";//流程表
$db->query($sql); //流程节点表
$arr = $_SESSION["jd"]; foreach($arr as $k=>$v){ $sql = "insert into flowpath values(0,'{$code}','{$v}',{$k})"; $db->query($sql);
}
break;
}效果如圖：
點選選擇節點人員可以從資料庫調所有人員名單，現在把李四，馬七和張三放入流程中，做一個請假流程：
注意:Code必須用varchar，不能用time，因為在上面花了時間戳
現在我們在做一個登陸用戶頁面flowlogin.php，提交請假流程的所有步驟：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/>
</head>
<style>
.-left:-top:.-left:-top: -.name,.-width:.-top:</style>
<body>
<form ="form-horizontal" role="form">
<h3 ="title">用户登录</h3>
<p ="quanju">
<p ="form-group yangshi1">
<label ="firstname" ="col-sm-2 control-label">用户名:</label>
<p ="col-sm-10">
<input type="text" ="form-control name" id="uid" placeholder="请输入用户名">

<p ="form-group">
<p ="col-sm-offset-2 col-sm-10">
<button type="button" id="login" ="btn btn-warning" value="登录" ></button>
</p>
</p>
</p>
</form>
</body>
<script>
"#login").click( uid = $("#uid"). pwd = $("#pwd")..:"post",:"flowloginchuli.php",:{uid:uid,pwd:pwd},:"TEXT",:(data.()=="OK".location.href="flowmain.php""用户名或密码有误!"</script>
</html>4.登入後跳轉的主頁flowmain.php
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title></title> </head> <body> <h2>主页面</h2> <a href="flowfq.php">发起流程</a> <a href="flowsh.php">审核流程</a> </body> </html>5.發起流程頁面flow.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
</head>
<body>
<h2>发起流程</h2>
<form action="flowfqchuli.php" method="post">
请选择流程： <select name="flow">
<?php require_once "./DBDA.class.php"; $db = new DBDA(); $sql = "select * from flow"; $arr = $db->query($sql,0); foreach($arr as $v){ echo "<option value='{$v[0]}'>{$v[1]}</option>";
} ?>
</select>
<br />
<br />
请输入内容： <textarea name="content"></textarea>
<br />
<br />
<input type="submit" value="确定" />
</form>
</body>
</html>6.做發起流程的處理頁面flowfq.php
<?phpsession_start();require_once "./DBDA.class.php";$db = new DBDA();
$code = $_POST["flow"];
$uid = $_SESSION["uid"];$content = $_POST["content"];
$time = date("Y-m-d H:i:s");
$sql = "insert into userflow values(0,'{$code}','{$uid}','{$content}',0,'{$time}',0)";$db->query($sql);header("location:flowmain.php");
7.審核頁面flowsh.php
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/>
</head>
<body>
<p><h2>审核页面</h2>
<table class="table table-bordered">
<thead>
<tr>
<th>流程代号</th>
<th>发起人</th>
<th>发起内容</th>
<th>通过状态</th>
<th>发起时间</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<?php session_start(); $uid = $_SESSION["uid"]; require_once "./DBDA.class.php"; $db = new DBDA(); //相关子查询(用到父查询的数据)(父查询卡在某一位置)
$sql = "select * from userflow a where towhere>=(select b.order from flowpath b where b.code=a.code and b.uid='{$uid}')";
$arr = $db->query($sql,0);
foreach($arr as $v){ //$v[6];//流程走到的位置towhere
//$v[1];//利用代号和session中存的name查询order
$sql = "select order from flowpath where code='{$v[1]}' and uid='{$uid}'"; $order = $db->StrQuery($sql,0);//该人员在流程中的次序
$str = ""; if($v[6]==$order){ //传主键值
$str = "<a href='flowtgchuli.php?ids={$v[0]}'>通过</a>";
}else{ $str = "<span style='color:green'>已通过</span>";
} echo "<tr>
<th>{$v[1]}</th>
<th>{$v[2]}</th>
<th>{$v[3]}</th>
<th>{$v[4]}</th>
<th>{$v[5]}</th>
<th>{$str}</th>
</tr>";
}
?>
</tbody>
</table>
</p>
</body>
</html>8.做審核頁面的處理頁面flowshchuli.php
<?php
session_start();
$uid = $_SESSION["uid"];require_once "./DBDA.class.php";
$db = new DBDA();$ids = $_GET["ids"];
$sql = "update userflow set towhere=towhere+1 where ids='{$ids}'";
$db->query($sql);//判断；流程是否结束(使用相关子查询)
$swc = "update userflow a set isok=1 where ids='{$ids}' towhere>=(select count(*) from flowpath b where b.code=a.code)";header("location:flowsh.php");流程效果如圖：
