上一篇随笔中已经提到如何新建流程,那么现在我们就来看一下如何发起一个流程和审核流程~~~
先说一下思路:
(1)登录用session获取到用户的id
(2) 用户发起一个流程
注意:需要写申请事由
(3)处于节点的审核人去依次审核
注意:每审核通过一个,对应towhere字段要加1; 审核到最后时,对应的isok字段要变为1(此处1表示结束,0表示未结束)
共用到三张表:
第一步:先做一个简单的登录页面,用session获取用户名:
denglu.php页面
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="UTF-8">
- <title></title>
- </head>
- <body>
- <form method="post" action="denglu-cl.php">
- 用户名:<input type="text" name="uid" /><br />
- 密码:<input type="password" name="pwd" /><br />
- <input type="submit" value="登录" />
- </form>
- </body>
- </html>
denglu-cl.php页面
- <?php
- session_start();
- require "../DB.class.php";
- $db = new DB();
- $uid = $_POST["uid"];
- $pwd = $_POST["pwd"];
- $sql = "select pwd from users where uid='{$uid}'";
- $mm = $db->strquery($sql);
- if($pwd==$mm && !empty($pwd))
- {
- $_SESSION["uid"]=$uid;
- header("location:liucheng.php");
- }
- else
- {
- echo "密码或登录名输入错误";
- }
- ?>
效果图:
第二步:做个简单的注页面:liucheng.php
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="UTF-8">
- <title></title>
- <style>
- #body{
- height: 200px;
- width: 300px;
- background-color: gainsboro;
- margin: 200px auto;
- text-align: center;
- vertical-align: middle;
- line-height: 30px;
- }
- </style>
- </head>
- <body>
- <p id="body">
- <h2>主页面</h2>
- <p>
- <a href="faqi.php" rel="external nofollow" >发起流程</a><br />
- <a href='shenhe.php'>审核流程</a>
- </p>
- </p>
- </body>
- </html>
效果图:
第三步:发起流程页面faqi.php
(1)先将所有流程用下拉列表显示
(2)发起流程事由需要由登录用户填写
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="UTF-8">
- <title></title>
- <style>
- #body{
- height: 250px;
- width: 300px;
- background-color: gainsboro;
- margin: 200px auto;
- text-align: left;
- vertical-align: middle;
- line-height: 30px;
- padding-left: 30px;
- }
- </style>
- </head>
- <body>
- <p id="body">
- <form method="post" action="faqi-cl.php">
- <h2>发起流程页面</h2>
- <select id="lc">
- <?php
- require "../DB.class.php";
- $db = new DB();
- $sql = "select * from liucheng";
- $arr = $db->query($sql);
- foreach($arr as $v)
- {
- echo "<option value='{$v[0]}'>{$v[1]}</option>";
- }
- ?>
- </select><br />
- 发起流程事由:
- <textarea class="nr"> </textarea><br />
- <input type="button" value="确定发起" />
- </form>
- </p>
- </body>
- </html>
第四步:写发起流程的处理页面fq-cl.php
- <?php
- session_start();
- require "../DB.class.php";
- $db = new DB();
- $code = $_POST["lc"];
- $nr =$_POST["nr"];
- $uid = $_SESSION["uid"];
- $time = date("Y-m-d H:i:s",time());
- $sql = "insert into liuchengpath values ('','{$code}','{$uid}','{$nr}',0,'{$time}',0)";
- $db->query($sql,0);
- header("location:liucheng.php");
- ?>
点击“确认发起”,数据库中就会添加此条数据
第五步:流程审核页面shenhe.php
用到知识点:子查询:无关子查询(子查询和父查询可以独立执行); 相关子查询(子查询里的条件使用到了父查询的某个东西 )
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="UTF-8">
- <title></title>
- <style>
- #body{
- height: 450px;
- width: 800px;
- background-color: gainsboro;
- margin: 200px auto;
- text-align: left;
- vertical-align: middle;
- line-height: 30px;
- padding-left: 30px;
- }
- </style>
- </head>
- <body>
- <p id="body">
- <h2>流程审核页面</h2>
- <?php
- session_start();
- $uid = $_SESSION["uid"];
- require "../DB.class.php";
- $db = new DB();
- //先取该用户参与的所有流程
- //并且取流程步骤到达该用户或已经被改用户审核通过的记录
- $sql="select * from liuchengpath a where code in(select code from liuchengjiedian where uids='{$uid}') and towhere >=(select orders from liuchengjiedian b where b.code = a.code and b.uids = '{$uid}')";
- $arr = $db->query($sql);
- //var_dump($arr);
- echo "<table border='1' width='100%' cellpadding='0' cellspacing='0'>
- <tr>
- <td>流程代号</td>
- <td>发起者</td>
- <td>发起内容</td>
- <td>发起时间</td>
- <td>是否结束</td>
- <td>操作</td>
- </tr>";
- foreach($arr as $v){
- //操作最后一列
- //设置默认项
- $zt = "<a href='tongguo-cl.php?code={$v[0]}'>审核未通过</a>";
- $sql = "select orders from liuchengjiedian where code ='{$v[1]}' and uids ='{$uid}'";
- $wz = $db->strquery($sql);
- if($v[6]>$wz)
- {
- $zt = "<span style='color:green'>审核已通过</span>";
- }
- echo "<tr>
- <td>{$v[1]}</td>
- <td>{$v[2]}</td>
- <td>{$v[3]}</td>
- <td>{$v[4]}</td>
- <td>{$v[5]}</td>
- <td>{$zt}</td>
- </tr>";
- }
- echo "</table>";
- ?>
- </p>
- </body>
- </html>
第六步:写tongguo-cl.php页面(重要)
- <?php
- $ids = $_GET["code"];
- require "../DB.class.php";
- $db = new DB();
- //点击审核后,towhere列加1,目的是使流程向下走
- $sql = "update liuchengpath set towhere = towhere+1 where ids ='{$ids}' ";
- $db->query($sql,0);
- //当流程走到最后一个审核的人时,流程要结束
- //获取该流程最大的orders
- $sql =" select max(orders) from liuchengjiedian where code = (select code from liuchengpath where ids ='{$ids}')";
- $maxorders = $db->strquery($sql);
- //获取该用户处于哪个位置,也就是towhere等于多少
- $sql ="select towhere from liuchengpath where ids ='{$ids}'";
- $towhere = $db->strquery($sql);
- //判断是否已到达最后一个审核的人
- if($towhere>$maxorders)
- {
- $sql = "update liuchengpath set isok=1 where ids='{$ids}'";
- // var_dump($sql);
- $db->query($sql,0);
- }
- header("location:shenhe.php");
- ?>
当写好这一步时,点击“审核未通过”则会变成“审核已通过”;
我们从头来验证一下效果:
首先:发起一个新的请假流程:
其次:zhangsan是第一个要审核人
点击“审核未通过后“,
最后:zhaoliu是最后一个审核人
点击“审核未通过”后,是否结束变为 1 ;操作变为绿色的 “审核已通过”~~~
