[下划线 请假系统源代码PHP]

请假是每个员工都可能面临的情况，为了规范请假流程并提高效率，许多公司采用了请假系统。下面是一个基于PHP的请假系统的源代码。

**1. 数据库设计：**

```sql

CREATE TABLE `leave_requests` (

`id` INT(11) NOT NULL AUTO_INCREMENT,

`employee_name` VARCHAR(255) NOT NULL,

`start_date` DATE NOT NULL,

`end_date` DATE NOT NULL,

`reason` TEXT NOT NULL,

`status` ENUM('Pending', 'Approved', 'Rejected') NOT NULL DEFAULT 'Pending',

`created_at` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

```

**2. 核心逻辑代码：**

- **index.php**：显示请假列表和添加请假表单。

```php

include('config.php');

include('functions.php');

$leaveRequests = getLeaveRequests();

?>

请假列表

添加请假申请

```

- **config.php**：保存数据库连接配置信息。

```php

$db_host = 'localhost';

$db_username = 'root';

$db_password = 'password';

$db_name = 'leave_system';

$conn = new mysqli($db_host, $db_username, $db_password, $db_name);

if ($conn->connect_error) {

die("连接数据库失败: " . $conn->connect_error);

}

?>

```

- **functions.php**：包含一些常用的函数。

```php

function getLeaveRequests() {

global $conn;

$sql = "SELECT * FROM leave_requests";

$result = $conn->query($sql);

$leaveRequests = array();

if ($result->num_rows > 0) {

while ($row = $result->fetch_assoc()) {

$leaveRequests[] = $row;

}

}

return $leaveRequests;

}

function addLeaveRequest($employee_name, $start_date, $end_date, $reason) {

global $conn;

$sql = "INSERT INTO leave_requests (employee_name, start_date, end_date, reason)

VALUES ('$employee_name', '$start_date', '$end_date', '$reason')";

if ($conn->query($sql) === TRUE) {

return true;

} else {

return false;

}

}

function approveLeaveRequest($id) {

global $conn;

$sql = "UPDATE leave_requests SET status='Approved' WHERE id=$id";

if ($conn->query($sql) === TRUE) {

return true;

} else {

return false;

}

}

function rejectLeaveRequest($id) {

global $conn;

$sql = "UPDATE leave_requests SET status='Rejected' WHERE id=$id";

if ($conn->query($sql) === TRUE) {

return true;

} else {

return false;

}

}

?>

```

- **add_request.php**：处理添加请假申请的请求。

```php

include('config.php');

include('functions.php');

if ($_SERVER['REQUEST_METHOD'] == 'POST') {

$employee_name = $_POST['employee_name'];

$start_date = $_POST['start_date'];

$end_date = $_POST['end_date'];

$reason = $_POST['reason'];

if (addLeaveRequest($employee_name, $start_date, $end_date, $reason)) {

header('Location: index.php');

exit();

} else {

echo '添加请假申请失败！';

}

}

?>

```

- **approve.php**：处理同意请假请求的操作。

```php

include('config.php');

include('functions.php');

if ($_SERVER['REQUEST_METHOD'] == 'GET' && isset($_GET['id'])) {

$id = $_GET['id'];

if (approveLeaveRequest($id)) {

header('Location: index.php');

exit();

} else {

echo '操作失败！';

}

}

?>

```

- **reject.php**：处理拒绝请假请求的操作。

```php

include('config.php');

include('functions.php');

if ($_SERVER['REQUEST_METHOD'] == 'GET' && isset($_GET['id'])) {

$id = $_GET['id'];

if (rejectLeaveRequest($id)) {

header('Location: index.php');

exit();

} else {

echo '操作失败！';

}

}

?>

```

以上是一个简单的请假系统的PHP源代码，通过该系统可以实现请假申请的添加、查看、审批等功能。可以根据实际需求拓展功能，例如添加员工信息、用户身份验证等。 如果你喜欢我们三七知识分享网站的文章， 欢迎您分享或收藏知识分享网站文章 欢迎您到我们的网站逛逛喔！https://www.ynyuzhu.com/
