php-process management (php+Ajax)

php+AJAX new process

1: Need to clarify which processes need to be operated?

2: What personnel are needed to execute each process?

3: What is the order of people performing this process?

1. The three tables required for database construction are: users table; liucheng table; flowpath table (the data has been displayed in the table)

2. Create a new process page

(1) Use Drop-down listDisplays the list of people and adds an add button

<h1 id="新建流程">新建流程</h1>
<p>
请选择节点人员：
	<select id="user">
    <?php
	session_start();
	require"../DBDA.class.php";
	$db = new DBDA();
	$sql = "select * from users";
	$arr = $db->query($sql,1);
	foreach($arr as $v)
	{
		echo"<option value=&#39;{$v[0]}&#39;>{$v[2]}</option>";  //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
	}
	?>
    </select>
    
<input type="button" value="添加节点" id="addjd" />
</p>
<br />

(2) Add a click event to the Add Node button

##

$("#addjd").click(function(){
		var uid = $("#user").val();
		$.ajax({
				url:"add.php",
				data:{uid:uid},
				type:"POST",
				dataType:"TEXT",
				success: function(data){
						window.location.href="xinjian.php";//执行处理页面成功后会刷新页面
					}
			}) 
	})

(3) Add a node The processing page add.php

<?php
session_start();
$uid = $_POST["uid"]; //接收传过来的值if(empty($_SESSION["jiedian"]))
{
	$arr = array($uid);//定义一个数组放用户
	$_SESSION["jiedian"] = $arr; //将第一个用户放入数组中}
else
{
	$arr = $_SESSION["jiedian"];//数组中有值
	$arr[] = $uid; //放入数组中值
	$_SESSION["jiedian"] = $arr; //将值再交给session}

(4) Display the added node

# in the new process page

##

<p>
<?php
if(empty($_SESSION["jiedian"]))
{
	echo"还未添加节点人员！";
}
else
{
	$arr = $_SESSION["jiedian"];
	foreach($arr as $k=>$v)
	{
		$sql ="select name from users where uid=&#39;{$v}&#39;";
		$name =$db->strquery($sql);
		echo"<p>{$k}--{$name}--<input type=&#39;button&#39; value=&#39;移除&#39; class=&#39;yichu&#39; sy=&#39;{$k}&#39;/></p>";
	}
}
?>
</p>
<br />

After completing this step, the effect is as follows:

(5) Add the remove button Click event

$(".yichu").click(function(){
		var sy = $(this).attr("sy"); //点击这个按钮，选中这个的索引号
		$.ajax({
			url:"yichu.php",
			data:{sy:sy},
			type:"POST",
			dataType:"TEXT",
			success: function(data){
				window.location.href="xinjian.php";//执行处理页面成功后会刷新页面
			}
		});
	})

(6) Remove the processing page yichu.php

<?php
session_start();

$sy =$_POST["sy"]; //接收穿过来的索引号$arr = $_SESSION["jiedian"];//节点的数组unset($arr[$sy]); //删除数据$arr = array_values($arr);//重新索引$_SESSION["jiedian"] = $arr;

(7) After the node problem is solved, then there is the name of the process. The text box for writing the name: The important thing is to save the process, so there must be a save button.

<p>
请输入流程名称：<input type="text" id="mingcheng" />
</p>
<br />
<input type="button" value="保存" id="baocun" />

(8) Add a click event to the save button

$("#baocun").click(function(){
	var name = $("#mingcheng").val();
	$.ajax({
		url:"baocun.php",
		data:{name:name},
		type:"POST",
		dataType:"TEXT",
		success: function(data){
			alert("保存成功！");
		}
	});
})	

(9) Finally, there is the processing page to save the process

<?php
session_start();
require "../DBDA.class.php";
$db = new DBDA();

$name = $_POST["name"];
$code = time();

$sql ="insert into liucheng values(&#39;{$code}&#39;,&#39;{$name}&#39;)";
$db->query($sql);

$arr = $_SESSION["jiedian"];

foreach($arr as $k=>$v)
{
	$sql ="insert into flowpath values(&#39;&#39;,&#39;{$code}&#39;,&#39;{$v}&#39;,{$k})"; //注意建表的类型，这里的orders项用的是int型，所以｛$k｝不用加&#39;&#39;，而且建表主键要勾选自增长
	$db->query($sql);
}

##Of course, the content is also stored in the database accordingly. The effect can be seen in the top data table

The following code is used for

copy

:
