如何使用PHP开发员工考勤系统?
随着科技的不断进步,越来越多的企业开始使用员工考勤系统来管理员工的考勤记录。使用PHP语言进行开发考勤系统可以快速高效地满足企业的需求。本文将介绍如何使用PHP开发一个简单的员工考勤系统,并提供具体的代码示例。
员工信息表设计如下:
CREATE TABLE employee (
id INT(11) PRIMARY KEY AUTO_INCREMENT, name VARCHAR(50) NOT NULL, position VARCHAR(50) NOT NULL
);
考勤记录表设计如下:
CREATE TABLE attendance (
id INT(11) PRIMARY KEY AUTO_INCREMENT, employee_id INT(11) NOT NULL, date DATE NOT NULL, check_in TIME NOT NULL, check_out TIME NOT NULL
);
$conn = mysqli_connect("localhost", "用户名", "密码", "数据库名");
// 添加员工信息
if(isset($_POST['add_employee'])){
$name = $_POST['name']; $position = $_POST['position']; $sql = "INSERT INTO employee (name, position) VALUES ('$name', '$position')"; mysqli_query($conn, $sql);
}
// 编辑员工信息
if(isset($_POST['edit_employee'])){
$employee_id = $_POST['employee_id']; $name = $_POST['name']; $position = $_POST['position']; $sql = "UPDATE employee SET name='$name', position='$position' WHERE id='$employee_id'"; mysqli_query($conn, $sql);
}
// 删除员工信息
if(isset($_POST['delete_employee'])){
$employee_id = $_POST['employee_id']; $sql = "DELETE FROM employee WHERE id='$employee_id'"; mysqli_query($conn, $sql);
}
// 获取员工列表
$sql = "SELECT * FROM employee";
$result = mysqli_query($conn, $sql);
?>

<h2>员工信息管理</h2> <!-- 添加员工表单 --> <h3>添加员工</h3> <form method="post" action="#"> <input type="text" name="name" placeholder="姓名" required> <input type="text" name="position" placeholder="职位" required> <input type="submit" name="add_employee" value="添加员工"> </form> <!-- 员工列表 --> <h3>员工列表</h3> <table> <tr> <th>ID</th> <th>姓名</th> <th>职位</th> <th>操作</th> </tr> <?php while($row = mysqli_fetch_assoc($result)): ?> <tr> <td><?php echo $row['id']; ?></td> <td><?php echo $row['name']; ?></td> <td><?php echo $row['position']; ?></td> <td> <form method="post" action="#"> <input type="hidden" name="employee_id" value="<?php echo $row['id']; ?>"> <input type="text" name="name" value="<?php echo $row['name']; ?>"> <input type="text" name="position" value="<?php echo $row['position']; ?>"> <input type="submit" name="edit_employee" value="编辑"> <input type="submit" name="delete_employee" value="删除"> </form> </td> </tr> <?php endwhile; ?> </table>
$conn = mysqli_connect("localhost", "用户名", "密码", "数据库名");
// 添加考勤记录
if(isset($_POST['add_attendance'])){
$employee_id = $_POST['employee_id']; $date = $_POST['date']; $check_in = $_POST['check_in']; $check_out = $_POST['check_out']; $sql = "INSERT INTO attendance (employee_id, date, check_in, check_out) VALUES ('$employee_id', '$date', '$check_in', '$check_out')"; mysqli_query($conn, $sql);
}
// 获取考勤记录列表
$sql = "SELECT * FROM attendance JOIN employee ON attendance.employee_id = employee.id";
$result = mysqli_query($conn, $sql);
?>
