Share examples of initiating process and review process using php+ajax
This article mainly introduces the php+ajax initiation process and review process (taking leave as an example). Friends who need it can refer to it
The previous essay has mentioned how to create a new process, so now Let’s take a look at how to initiate a process and review process~~~
Let’s talk about the idea first:
(1) Log in with session Obtain the user's id
(2) The user initiates a process
Note: You need to write the application reason
(3) The reviewer at the node will review it in sequence
Three tables:
<!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>
<?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";
}
?>
<!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>

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>
<?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");
?>
##Step 5: Process review page shenhe.php
Knowledge points used: subquery: irrelevant subquery (subquery and parent query can be executed independently); related subquery (the conditions in the subquery use something from the parent query )
<!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>

<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>Sixth Step: Write tongguo-cl.php page (important)
<?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");
?>After writing this step, click "Audit failed" and it will change to "Audit passed";
Let’s verify the effect from the beginning:
First: initiate a new leave process:
Second: zhangsan Is the first person to be reviewed
Click "After review failed",
Finally: zhaoliu is the last reviewer
##After clicking "Audit failed", whether the end is changed to 1; The operation changes to green "Audit passed"~~~
