PHP と Vue を組み合わせて従業員の勤怠管理のチェックインおよびチェックアウト機能を実装する方法

<?php
include 'db_connect.php';

// 接收从前台传来的员工ID
$employee_id = $_POST['employee_id'];

// 获取当前时间
$sign_in_time = date('Y-m-d H:i:s');

// 将签到信息插入到数据库
$sql = "INSERT INTO attendance (employee_id, sign_in_time) VALUES ('$employee_id', '$sign_in_time')";
$result = mysqli_query($conn, $sql);

if ($result) {
  echo "签到成功";
} else {
  echo "签到失败";
}

// 接收从前台传来的员工ID
$employee_id = $_POST['employee_id'];

// 获取当前时间
$sign_out_time = date('Y-m-d H:i:s');

// 更新签退时间
$sql = "UPDATE attendance SET sign_out_time = '$sign_out_time' WHERE employee_id = '$employee_id'";
$result = mysqli_query($conn, $sql);

if ($result) {
  echo "签退成功";
} else {
  echo "签退失败";
}
