How to use PHP and Vue to develop abnormal data processing for online employee attendance

Overview:
As an important part of modern enterprise management, the online employee attendance system For managers, handling abnormal attendance data is a necessary and important task. This article will introduce how to use PHP and Vue to develop the abnormal data processing function of online employee attendance, and provide corresponding code examples.

1. Preparation work:
   Before starting development, you need to ensure that the PHP environment and Vue.js framework have been installed. PHP is a server-side scripting language used to handle back-end logic; Vue.js is a JavaScript framework used to build user interfaces to handle front-end logic.
2. Database design:
   First, you need to design a database to store employee attendance data. Attendance data can include employee information, attendance time, attendance status, etc. Relational databases such as MySQL can be used for storage.
3. Back-end development:
   Use PHP to write the back-end interface to handle the query and modification operations of abnormal attendance data. The following is a simple sample code:

// 连接数据库
$connection = mysqli_connect('localhost', 'username', 'password', 'database');

// 查询异常考勤数据
function getExceptionData($date) {
  global $connection;

  $query = "SELECT * FROM attendance WHERE date = '$date' AND status != 'normal'";
  $result = mysqli_query($connection, $query);

  $exceptionData = [];
  while ($row = mysqli_fetch_assoc($result)) {
    $exceptionData[] = $row;
  }

  return $exceptionData;
}

// 修改异常考勤数据
function updateExceptionData($id, $status) {
  global $connection;

  $query = "UPDATE attendance SET status = '$status' WHERE id = $id";
  mysqli_query($connection, $query);
}

The above code uses the mysqli library to connect to the database and provides two functions: getExceptionData is used to query abnormal attendance data, and updateExceptionData is used to modify abnormal attendance data.

4. Front-end development:
   Use Vue.js to write the front-end page to display abnormal attendance data and provide modification functions. The following is a simple sample code:

<template>
  <div>
    <h1 id="异常考勤数据处理">异常考勤数据处理</h1>
    <table>
      <tr v-for="data in exceptionData" :key="data.id">
        <td>{{ data.employee }}</td>
        <td>{{ data.date }}</td>
        <td>{{ data.status }}</td>
        <td>
          <select v-model="data.status" @change="updateData(data.id, data.status)">
            <option value="normal">正常</option>
            <option value="late">迟到</option>
            <option value="absent">缺勤</option>
          </select>
        </td>
      </tr>
    </table>
  </div>
</template>

<script>
  export default {
    data() {
      return {
        exceptionData: []
      };
    },
    mounted() {
      this.getExceptionData();
    },
    methods: {
      getExceptionData() {
        // 发起后端接口请求，获取异常考勤数据
        // 使用axios库进行网络请求
        axios.get('/api/exceptionData')
          .then(response => {
            this.exceptionData = response.data;
          })
          .catch(error => {
            console.error(error);
          });
      },
      updateData(id, status) {
        // 发起后端接口请求，修改异常考勤数据
        axios.post('/api/updateData', { id, status })
          .then(response => {
            console.log(response.data);
          })
          .catch(error => {
            console.error(error);
          });
      }
    }
  }
</script>

The above code uses the single-file component method of Vue.js to display abnormal attendance data and provide modification functions. Obtain the data returned by the backend interface through the getExceptionData method, and send the modified data to the backend interface using the updateData method.

5. Integrate back-end and front-end:
   Integrate the back-end and front-end code together and run them through a web server such as Apache or Nginx. At the same time, configure routing and interface proxies so that the front end can correctly call the back end interface. In PHP code, you can use lightweight PHP frameworks such as Slim for routing processing.

Summary:
Through the above steps, we can use PHP and Vue to develop an exception data processing function for online employee attendance. Query and modify abnormal attendance data through the back-end interface, combined with front-end interface display and interaction, to provide a convenient and fast way to handle abnormal data.

Note that the above sample code is just a simple reference, and may need to be appropriately adjusted and optimized according to specific needs in actual development.

I hope this article will help you understand how to use PHP and Vue to develop exception data processing for online employee attendance. Happy development!
