This article mainly introduces the use of php+ajax to create a new process (leave request, purchase, shipment, etc.). Friends in need can refer to it
For managers, the computer-operated leave request process is better than The manual leave process is much more efficient, so how to create a new process?
First of all: What processes need to be clarified?
Secondly: Which personnel are needed to execute each process?
Finally: What is the order of people performing this process?
Step one: Three tables are needed, namely: user table; liucheng table; liuchengjiedian table (the last two have not been added yet)
Step 2: Use the drop-down list to read the contents of the users table:
<p id="top"> <p>请选择节点人员:</p> <select id="user"> <?php require "../DB.class.php"; $db = new DB(); $sql = "select * from users"; $arr = $db->query($sql); foreach ($arr as $v){ echo "<option value='{$v[0]}'>{$v[2]}</option>"; } ?> </select> <input type="button" value="确定添加"/> </p>
Implementation effect:
Step 3: Click "Confirm Add" to add the selected person to session
(1) First introduce the jquery package
<script src="../jquery-1.11.2.min.js"></script>
(2)ajax code
<script type="text/javascript"> //用session 存取选择的值 $("#add").click(function(){ var uid = $("#user").val(); // alert(uid); $.ajax({ url:"add-cl.php", data:{uid:uid}, type:"POST", dataType:"TEXT", success:function(data){ window.location.href="main.php" rel="external nofollow" rel="external nofollow" ; } }); }) </script>
(3)add-cl.php page
<?php //开启session session_start(); //取值 $uid=$_POST["uid"]; //如果session为空,造一个数组,将取到的值添加进去 if(empty($_SESSION["jiedian"])){ $arr = array($uid); $_SESSION["jiedian"] = $arr; } //如果不为空,将取到的值追加进去 else { $arr = $_SESSION["jiedian"]; $arr[]=$uid; $_SESSION["jiedian"] = $arr; } ?>
Step 4: List the selected people
(1)Judge first Whether to get the value of session
<?php session_start(); if(empty($_SESSION["jiedian"])){ echo "尚未选择节点人员!"; }
(2) After getting the session
else { $arr = $_SESSION["jiedian"]; foreach($arr as $k=>$v) { $sql = "select name from users where uid='{$v}'"; $name = $db->strquery($sql); echo "<p>{$k}--{$name}--<input type ='button' value='移除' class='yichu' code='{$k}'> <p>"; } } ?>
(3) Add a click event to the "Remove" button
ajax page:
$(".yichu").click(function(){ var code = $(this).attr("code"); $.ajax({ url:"yichu-cl.php", data:{code:code}, type:"POST", dataType:"TEXT", success:function(data){ window.location.href="main.php" rel="external nofollow" rel="external nofollow" ; } }); })
yichu-cl.php page:
<?php session_start(); $code = $_POST["code"]; $arr = $_SESSION["jiedian"]; //从数组中删除code这一项 unset($arr[$code]); //将索引重新排列 $arr = array_values($arr); $_SESSION["jiedian"] = $arr; ?>
Click to remove Wang Wu: Zhang San and Saturday will remain, and the codes will be rearranged
The last step: add a save button and add the data to Database
Note: All data before this exists in the session
(1) Add process name input box and save button
<p id="btm"> 请输入流程名称: <input type="text" class="name" /> <input type="button" value="保存" class="baocun" /> </p>
(2) Click Save button to store all information in the database
ajax code
$(".baocun").click(function(){ var name = $(".name").val(); // alert(name); $.ajax({ url:"baocun-cl.php", data:{name:name}, type:"POST", dataType:"TEXT", success:function(data){ alert("保存成功!"); } }); })
baocun-cl.php page
<?php session_start(); require "../DB.class.php"; $db = new DB(); //将数据写进liucheng表 $name = $_POST["name"]; $code=time();//用时间戳来生成code $sql = "insert into liucheng values('{$code}','{$name}')"; $db->query($sql,0); //将数据写入liucehngjiedian表 $arr = $_SESSION["jiedian"]; foreach($arr as $k=>$v) { $sql = "insert into liuchengjiedian values ('','{$code}','{$v}','{$k}')"; $db->query($sql,0); } ?>
Implementation effect and data written to the database:
At this step, the entire Liu Xinjian process steps can be realized, and the interface can be beautified a little later~~~~
Summary: Each step of the processing page is more important; sessoin accesses data; unsettle() removes the array; array_values() rearranges the array, etc.~~~

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.
