How to use PHP and Vue to develop an online employee attendance card replacement application module

Introduction:
With the development of information technology, many companies have begun to adopt online Employee attendance system to manage employee attendance. In actual work, employees may need to replace their cards due to some special reasons. Therefore, we need to develop an online employee attendance card replacement application module. This article will introduce how to use PHP and Vue to implement this function, and provide specific code examples.

Technical Selection:
When developing this card replacement application module, we will use PHP as the back-end language to handle server-side logical operations and database interaction. On the front-end side, we will use Vue as a JavaScript framework to implement user interface interaction and data transmission.

Back-end development:
First, we need to create a PHP file to handle the logical operation of card replacement application. In this file, we will use PHP's database operation function to connect to the database and write corresponding SQL statements to complete operations such as data query, insertion, and update.

//Connect to the database
$conn = new mysqli("localhost", "username", "password", "database");

/ / Check whether the database connection is successful
if ($conn->connect_error) {

die("数据库连接失败: " . $conn->connect_error);
Copy after login

}

// Process the logical operation of card replacement application
if ($_SERVER[ "REQUEST_METHOD"] == "POST") {

// 获取补卡申请提交的表单数据
$employee_id = $_POST["employee_id"];
$date = $_POST["date"];
$reason = $_POST["reason"];

// 编写SQL语句,将补卡申请数据插入到数据库中
$sql = "INSERT INTO attendance (employee_id, date, reason) VALUES ('$employee_id', '$date', '$reason')";

if ($conn->query($sql) === TRUE) {
    echo "补卡申请成功";
} else {
    echo "补卡申请失败: " . $conn->error;
}

$conn->close();
Copy after login

}
?>

Front-end development:
Next, we will use Vue to implement the front-end user interface and Interact with data from the backend. We can use Vue's component development to build a card replacement application form, and use the API provided by Vue to send a POST request to submit the data to the backend.
