如何使用PHP和Vue开发在线员工考勤的异常数据处理

// 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);
}

<template>
  <div>
    <h1>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>
