How to generate an overtime settlement module for employee attendance through PHP and Vue

Abstract: This article will introduce how to implement an overtime settlement module for employee attendance through PHP and Vue technology. First, we will use PHP to write server-side code to handle data requests and calculate overtime hours. Then, we will use the Vue framework to build a front-end interface so that users can submit attendance records through the web page and view information such as overtime hours and overtime expenses. At the end of the article, we will give some specific code examples to help readers better understand and practice.

1. Introduction
In enterprise management, overtime settlement is an important process. In order to facilitate employees and managers to count and calculate working hours, we can use PHP and Vue technology to build an overtime settlement module. Through the web interface, employees can submit overtime records and view information such as overtime hours and overtime pay.

2. Server-side code writing

1. Database table design
   First, we need to design a database table to store employee attendance information. The table structure can contain the following fields: attendance date, clock-in time, overtime start time, overtime end time, overtime duration, etc.
2. PHP code writing
   First, we need to write a PHP script to process data requests and calculate overtime hours. This script can include the following functions:
3. Receive the attendance records submitted by the client and insert them into the database.
4. Calculate employees’ overtime hours based on their punch-in time and set working hours.
5. Calculate employees’ overtime pay according to the overtime pay regulations established by the company.

The following is a simple PHP code example:

<?php
// 连接数据库
$db = new PDO('mysql:host=localhost;dbname=test', 'root', 'password');

// 接收POST请求，插入考勤记录
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $attendanceData = $_POST['attendanceData'];
    
    // 将考勤数据插入数据库
    $insertAttendanceStmt = $db->prepare('INSERT INTO attendance (date, start_time, end_time) VALUES (?, ?, ?)');
    $insertAttendanceStmt->execute([$attendanceData['date'], $attendanceData['start_time'], $attendanceData['end_time']]);
}

// 计算加班时长和加班费用
$calculateOvertimeStmt = $db->prepare('SELECT SUM(TIME_TO_SEC(TIMEDIFF(end_time, start_time))) AS overtimeDuration FROM attendance');
$calculateOvertimeStmt->execute();
$overtimeDuration = $calculateOvertimeStmt->fetchColumn();

$overtimeFee = $overtimeDuration * 10;   // 假设每小时加班费用为10元

// 将加班时长和加班费用返回给客户端
$response = [
    'overtimeDuration' => $overtimeDuration,
    'overtimeFee' => $overtimeFee
];
echo json_encode($response);
?>

3. Front-end interface construction

1. Install Vue and Vue Router
   First, we need to install Vue and Vue Router. It can be installed through the npm command:

   $ npm install vue vue-router

2. Create Vue component
   Next, we can create a Vue component to display employee attendance records and overtime information. You can define the required variables in the data attribute of the component, and then use these variables in the template for display.

The following is a simple Vue component example:

<template>
  <div>
    <h2 id="员工加班记录">员工加班记录</h2>
    <ul>
      <li v-for="record in attendanceRecords">
        {{ record.date }} - {{ record.start_time }} ~ {{ record.end_time }}
      </li>
    </ul>
    <h2 id="加班信息">加班信息</h2>
    <p>加班时长：{{ overtimeDuration }}</p>
    <p>加班费用：{{ overtimeFee }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      attendanceRecords: [],
      overtimeDuration: 0,
      overtimeFee: 0
    };
  },
  mounted() {
    // 向服务器请求加班信息
    fetch('/calculate-overtime.php')
      .then(response => response.json())
      .then(data => {
        this.overtimeDuration = data.overtimeDuration;
        this.overtimeFee = data.overtimeFee;
      });
    
    // 向服务器请求考勤记录
    fetch('/attendance-records.php')
      .then(response => response.json())
      .then(data => {
        this.attendanceRecords = data;
      });
  }
};
</script>

3. Configuring routing
   We also need to configure Vue Router to manage the routing of the page. You can add the following code in the main file to create a routing instance and associate the component with the path:

   import Vue from 'vue';
   import VueRouter from 'vue-router';
   import AttendanceComponent from './components/AttendanceComponent.vue';
   
   Vue.use(VueRouter);
   
   const routes = [
     { path: '/attendance', component: AttendanceComponent }
   ];
   
   const router = new VueRouter({
     routes
   });
   
   new Vue({
     router
   }).$mount('#app');

4. Summary
By using PHP and Vue technology, we can easily Conveniently implement an employee overtime settlement module. Through the web interface, employees can submit overtime records and view information such as overtime hours and overtime pay. This article gives a simple code example, hoping to help readers better understand and practice. Of course, more functional and security issues may need to be considered in actual projects, which need to be adjusted and improved according to specific circumstances.
