A complete process explanation about PHP process management-PHP Tutorial-php.cn

What is the usage of process management?

1. To have the content of the database

there will definitely be tables. The first is the user table, then the process table, the process table written by the user, and Table with auditors

2. After the database is completed, there is a page for creating a new process. This page will There are reviewers, as well as the name of the process and the submit button

(1) The person who adds the node, this is to traverse the database to see what the managers are

<p>
　　请选择节点人员：
    
    <?php
	session_start();   //开启session
	include("DBDA.class.php");   //调用封装好的数据库
	$db = new DBDA();  //造新对象
	
	$suser = "select * from users";  //查询用户表中的所有值
	$auser = $db->Query($suser);  //执行查询语句
	foreach($auser as $v)
	{
		echo "<input class=&#39;ck&#39; type=&#39;radio&#39; value=&#39;{$v[0]}&#39; name=&#39;ck&#39; />{$v[2]} ";  //输出单选按钮，数组中的索引2，也就是用户名，但是它的值是代号
	}
	?>
</p>

Copy after login

Check the displayed results ：

(2) After selecting the reviewer, there is an add button

<input type="button" value="添加节点" id="insert" />  //起个名字，便于给它添加单击按钮

Copy after login

(3) Add a click event to this button

$("#insert").click(function(){
	var ck = $(".ck");  //找到项
	var uid = "";
	for(var i=0;i<ck.length;i++)
	{
		if(ck.eq(i).prop("checked"))  //单选按钮的选中状态
		{
		　　uid = ck.eq(i).val();  //单选按钮的值
		}
	}
		
	$.ajax({
		url:"addjd.php",  //添加节点的处理页面
		data:{uid:uid},  //将单选按钮的值传过去
		type:"POST",  //传值方式
		dataType:"TEXT",  //值的返回状态
		success: function(data){
			window.location.href="liucheng_gaunli.php";  //执行处理页面成功后会刷新页面
		　　}
		});	
})

Copy after login

(4) Add the processing page of the node

<?php
session_start();  //开启session
$uid = $_POST["uid"];  //接收传过来的值

if(empty($_SESSION["jiedian"]))
{
	$attr = array($uid);  //定义一个数组放用户
	$_SESSION["jiedian"] = $attr; //将第一个用户放入数组中
}
else
{
	$attr = $_SESSION["jiedian"]; //数组中有值
	$attr[] = $uid;  //放入数组中值
	$_SESSION["jiedian"] = $attr;   //将值再交给session
}

Copy after login

(5) Display the added nodes in the main page

<?php
if(empty($_SESSION["jiedian"]))   //如果没有节点值
{
	echo "<p>还没有添加节点</p>";  //输出这句话
}
else
{
	$attr = $_SESSION["jiedian"];  //数组中有了值
	foreach($attr as $k=>$v)  //循环遍历，$v只是名字，还有有所以所以用$k
	{
		$sname = "select name from users where uid=&#39;{$v}&#39;";  //编写查询语句
		$name = $db->StrQuery($sname);  //执行查询语句
　　　　　　　　　　//输出索引号还有名字，加一个删除按钮吧，可以吧这个节点删除
		echo "<p>{$k}--{$name}--<input type=&#39;button&#39; value=&#39;删除&#39; sy=&#39;{$k}&#39; class=&#39;sc&#39; /></p>";  
	}
}
?>

Copy after login

Add node to see The following effect:

1. The rendering of the node that has not been added yet:

2. Just add a few reviewers: the staff have been displayed

(6) After this, add a click event to its delete button

$(".sc").click(function(){
	var sy = $(this).attr("sy");  //点击这个按钮，选中这个的索引号
	$.ajax({
		url:"shanchu.php",   //删除按钮的处理页面
		data:{sy:sy},  //把索引号传到处理页面
		type:"POST",  //传值方式
		dataType:"TEXT",
		success:function(data){
			window.location.href="liucheng_gaunli.php";  //执行处理页面成功后会刷新页面
		}
	});
})

Copy after login

(7) Delete button processing page

<?php
session_start();  //开启session
$attr = $_SESSION["jiedian"];  //节点的数组
$sy = $_POST["sy"];  //接收穿过来的索引号

unset($attr[$sy]); //删除数据
$attr = array_values($attr); //重新索引
$_SESSION["jiedian"] = $attr;

Copy after login

Check the effect of deleting a node

1. Before deletion

2.After deleting a node

(8) After the operation of the node has ended, then there is the name of the process. This is simple, write the name in the text box: the important thing is to save the process, then there must also be a save button

<p>请输入流程名称：<input type="text" id="name" /></p>    //起个名字，下面保存的写个单击事件有用

Copy after login

<p><input type="button" value="保存" id="save" /></p>  //保存按钮要有单击事件的

Copy after login

The overall effect diagram will come out:

(9) Finally, save the click event of the button

$("#save").click(function(){
　　var name = $("#name").val();  //取到文本框的值
　　$.ajax({
	url:"baocun.php",  //保存的处理页面
	data:{name:name},  //将文本框的值传到处理页面
	type:"POST",  //传值方式
	dataType:"TEXT",
	success: function(data){
		alert("添加成功！");  //执行处理页面成功后会弹出提示框
	　　}
　　});
})

Copy after login

(10) Save Process processing page

<?php
session_start();  //开启session
include("DBDA.class.php");  //调用封装的数据库类
$db = new DBDA();  //造新对象

$name = $_POST["name"];  //接收传过来的值
$code = time();  //代号是时间

$sflow = "insert into flow values(&#39;{$code}&#39;,&#39;{$name}&#39;)"; //修改流程表中的值：代号和名字
$db->Query($sflow,0);  //执行语句

$attr = $_SESSION["jiedian"];  
foreach($attr as $k=>$v)
{
	$spath = "insert into flowpath values(&#39;&#39;,&#39;{$code}&#39;,&#39;{$v}&#39;,&#39;{$k}&#39;)";  //修改流程节点的数值
	$db->Query($spath,0);  //执行语句
}

Copy after login

Look at the saving effect:

Look at the database, the content is also saved in the database

3. The new process page has ended, then it is the User Login page. I have written this page many times, so I won’t say more, just go to the code

( 1) The basic display of login: they are all basic statements

<h1>用户登录</h1>
<p>账号：<input type="text" id="uid" /></p> 
<p>密码：<input type="password" id="pwd" /></p>
<p><input type="button" value="登录" id="btn" /></p>

Copy after login

(2) Log in here, let’s also use ajax to log in

$("#btn").click(function(){  //对登录按钮添加单击事件
　　var uid=$("#uid").val();  //获取用户的值
　　var pwd=$("#pwd").val();  //获取密码的值
　　$.ajax({
    url:"logincl.php",  //编写登录的处理页面
    data:{uid:uid,pwd:pwd},  //将用户和密码传到处理页面
    type:"POST",
    dataType:"text",
    success: function(data)
    {
    　　if(data.trim()=="OK")
    　　{
    　　　　window.location.href="main.php";    //处理页面执行成功后，跳转到主页面
    　　}
    　　else
    　　{
    　　　　alert("用户名密码输入错误");  //否则就提示错误
    　　}
    }
　　})       
})

Copy after login

(3) Take a look at the writing of the processing page

<?php
session_start();  //开启session
include("DBDA.class.php");  //调用封装的类
$db = new DBDA();  //造新对象
//传过来的值
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];<br>//查询语句
$sql = " select pwd from users where uid=&#39;{$uid}&#39; and pwd=&#39;{$pwd}&#39; ";
//执行语句
$attr = $db->Query($sql);
if(!empty($pwd) && !empty($attr) && $attr[0][0]==$pwd)
{
    $_SESSION["uid"] = $uid; //session接收用户值
    echo "OK"; 
}
else
{
    echo "ON"; 
}
?>

Copy after login

Finally, let’s take a look at the final result. If you successfully log in, you will enter the homepage. If you fail to log in, you will be prompted with an error

Four , the audit processing interface for node users (there are many things that need to be paid attention to in this audit interface)

(1) The display part of the successful login interface: not everyone’s successful login interface is the same, and there are If this person does not participate in the review, there should be no information.

The header you want to display is one row: We can use a table to display it

<tr>
   <td>流程代号</td>
   <td>发起者</td>
   <td>发起内容</td>
   <td>是否结束</td>
   <td>发起时间</td>
   <td>操作</td>
</tr>

Copy after login

First look at the table below Header display:

(2) Open the session so that the login information will be saved

session_start();
include("DBDA.class.php");  //会用到数据库，所以可以调用一下数据库的类
$db = new DBDA();  //造新对象
$uid = "";
if(empty($_SESSION["uid"]))  //判断保存的session值是不是为空
{
　　header("location:login.php");  //为空就返回登录页面
}
else
{
　　$uid = $_SESSION["uid"];  //不为空就输保存一下用户
}

Copy after login

（3）接下来就是用户这是不是和流程有关系？流程走到哪了（分情况）？还有就是有没有通过

//查询登录者参与的所有流程
$su_flow = "select * from userflow where code in(select code from flowpath where uids=&#39;{$uid}&#39;)";
$au_flow = $db->Query($su_flow);  //执行查询语句
				
foreach($au_flow as $vu_flow)
{
　　$towhere = $vu_flow[6]; //流程走到哪里了
					
　　//找到登录者在该流程中的位置
　　$s_weizhi = "select orders from flowpath where code=&#39;{$vu_flow[1]}&#39; and uids=&#39;{$uid}&#39;";
　　$wezhi = $db->StrQuery($s_weizhi); //该人员在流程中的位置
					
　　if($towhere>=$wezhi)
　　{
　　　　$caozuo = "";
　　　　if($towhere==$wezhi)
　　　　{
	　　//流程正好走到登录者位置
	　　$caozuo="<a href=&#39;tongguo.php?ids={$vu_flow[0]}&#39;>通过</a>"; //get方式传过处理页面
　　　　}
　　　　else
　　　　{
	　　//流程走过登录者
	　　$caozuo = "<span style=&#39;background-color:green; color:white&#39;>已通过</span>";
　　　　}
　　　　echo "<tr><td>{$vu_flow[1]}</td><td>{$vu_flow[2]}</td><td>{$vu_flow[3]}</td><td>{$vu_flow[4]}</td><td>{$vu_flow[5]}</td><td>{$caozuo}</td></tr>";
　　}
　　else
　　{
　　　　//流程未走到登录者
　　}
}

Copy after login

（4）通过的处理页面

<?php
include("DBDA.class.php");  //调用封装好的数据库类
$db = new DBDA();  //造新对象
$ids = $_GET["ids"];  //将代号传过来
$sql = "update userflow set towhere=towhere+1 where ids=&#39;{$ids}&#39;";  //修改towhere的值看已经执行到哪了
$db->Query($sql,0);  //执行修改语句

$swhere = "select * from userflow where ids=&#39;{$ids}&#39;";  
$attr = $db->Query($swhere);

$towhere = $attr[0][6]; //走到哪了
$code = $attr[0][1]; //流程代号
$ssl = "select count(*) from flowpath where code=&#39;{$code}&#39;";   //查询总数
$pcount = $db->StrQuery($ssl); //该流程节点人员数量

if($towhere>=$pcount)
{
　　$sql = "update userflow set isok=true where ids=&#39;{$ids}&#39;";  //修改是不是已经通过了
　　$db->Query($sql,0);
}
header("location:main.php");

因为还没有写发起流程界面，那么先从数据库中添加几条数据看看：

（1）我们先要新建个流程，这是第一个页面，我们就用新建流程

看下结点还有流程名称来看下数据库中结点的表

根据这些我们在流程表中自己先添加信息吧，等后来再通过发起流程添加，现在只看下效果

登录审核人员的账号看下：

第一个人是李四：

我们点击通过，继续往下走

第二个人是马七，我们不点通过，看下下一个人员（王五）有没有这个通过的操作：是没有这个操作的

我们让马七通过审核，再看下王五的界面

王五的界面就是：就发现有了这个操作，继续下去，我们看下最后这个通过会不会变成1

最后审核人员张三

看下结果是否会结束：

再看下数据库中towhere中的数值是不是已经结束了：

这个就剩下发起流程的步骤了，可以先看下效果：

（1）发起流程有个链接页面，单击这个，可以链接到发起流程页面

（2）这个及时发起流程的页面了

这个挺简单的了，后面再更新吧~~~

至此，这个流程管理就结束了~~
