Application of employee resignation application module developed using PHP in enterprise resource planning (ERP) system

With the development and changes of enterprises, employee resignation application management has become an important task. To increase efficiency and accuracy, many businesses are integrating employee separation applications into their enterprise resource planning (ERP) systems. This article will introduce how to use PHP to develop an employee resignation application module and apply it to the ERP system.

Before developing the employee resignation application module, we first need a basic ERP system. The system can include functions such as employee management, resignation process management, notifications and approvals. In this article, we assume that such a system already exists, and our goal is to integrate the employee separation application module into this system.

First, we need to create a database table to store employee resignation application data. Taking MySQL as an example, we can create a table named "employee_resignation", containing the following fields:

CREATE TABLE employee_resignation (
    id INT AUTO_INCREMENT PRIMARY KEY,
    employee_id INT,
    reason VARCHAR(255),
    submitted_date TIMESTAMP,
    status ENUM('pending', 'approved', 'rejected')
);

Next, we can use PHP to implement the function of the employee resignation application module. First, we need to create a page to display the list of employee resignation applications, as shown below:

<?php
// 假设这里已经包含了连接数据库的代码和检查用户登录状态的代码

// 查询所有员工离职申请
$sql = "SELECT * FROM employee_resignation";
$result = mysqli_query($conn, $sql);

// 显示员工离职申请列表
while ($row = mysqli_fetch_assoc($result)) {
    echo "申请ID：" . $row['id'] . "<br>";
    echo "员工ID：" . $row['employee_id'] . "<br>";
    echo "离职原因：" . $row['reason'] . "<br>";
    echo "提交日期：" . $row['submitted_date'] . "<br>";
    echo "状态：" . $row['status'] . "<br>";
    echo "<br>";
}
?>

The above code will read the data of employee resignation applications from the database and display it on the page.

Next, we can create a page for submitting employee resignation applications, as shown below:

<?php
// 假设这里已经包含了连接数据库的代码和检查用户登录状态的代码

// 检查是否有POST请求提交
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $employeeId = $_POST['employee_id'];
    $reason = $_POST['reason'];

    // 插入员工离职申请到数据库
    $sql = "INSERT INTO employee_resignation (employee_id, reason, submitted_date, status) VALUES ('$employeeId', '$reason', NOW(), 'pending')";
    mysqli_query($conn, $sql);
}
?>

<form method="POST">
    <label for="employee_id">员工ID:</label>
    <input type="text" name="employee_id" id="employee_id" required><br>
    <label for="reason">离职原因:</label>
    <textarea name="reason" id="reason" required></textarea><br>
    <button type="submit">提交</button>
</form>

The above code will display a form where the user can enter the employee ID and reason for resignation, and Submit the resignation application to the database.

Finally, we can create a page for processing employee resignation application approval, as shown below:

<?php
// 假设这里已经包含了连接数据库的代码和检查用户登录状态的代码

// 检查是否有POST请求提交
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $id = $_POST['id'];
    $status = $_POST['status'];

    // 更新员工离职申请的状态
    $sql = "UPDATE employee_resignation SET status='$status' WHERE id='$id'";
    mysqli_query($conn, $sql);
}
?>

<form method="POST">
    <label for="id">申请ID:</label>
    <input type="text" name="id" id="id" required><br>
    <label for="status">状态:</label>
    <select name="status" id="status" required>
        <option value="approved">已批准</option>
        <option value="rejected">已拒绝</option>
    </select><br>
    <button type="submit">提交</button>
</form>

The above code will display a form where the administrator can enter the application ID and select the resignation application status and submit the approval results to the database.

Through the above code example, we can see how to use PHP to develop an employee resignation application module and apply it to an enterprise resource planning (ERP) system. By integrating the employee resignation application module, companies can improve the efficiency and accuracy of resignation management and provide employees with a better resignation experience.
