PHP Study Notes: Human Resource Management and Recruitment System

Human resource management plays a vital role in modern enterprises. With the development of technology, many companies are turning to information technology to manage their human resources. As a popular server-side scripting language, PHP is widely used to develop various enterprise application systems, including human resources management and recruitment systems. This article will introduce how to use PHP to develop a simple human resources management and recruitment system, and provide some specific code examples.

Create database

First, we need to create a database to store employee and job applicant information. MySQL or other relational databases can be used. Here is an example of creating an employee table and an applicant table:

CREATE TABLE employees (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(50) NOT NULL,
  email VARCHAR(50) NOT NULL,
  position VARCHAR(50) NOT NULL
);

CREATE TABLE applicants (
  id INT PRIMARY KEY AUTO_INCREMENT,
  name VARCHAR(50) NOT NULL,
  email VARCHAR(50) NOT NULL,
  position VARCHAR(50) NOT NULL,
  resume TEXT NOT NULL
);

Connecting to the database

Connecting to the database using PHP is very simple. Here is an example of connecting to a MySQL database:

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "hr_management";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}
echo "连接成功";
?>

Add employees and applicants

Here is an example code to add employee and applicant records to the database :

<?php
// 处理添加员工的请求
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["add_employee"])) {
    $name = $_POST["name"];
    $email = $_POST["email"];
    $position = $_POST["position"];

    // 插入记录到员工表
    $sql = "INSERT INTO employees (name, email, position) VALUES ('$name', '$email', '$position')";
    if ($conn->query($sql) === TRUE) {
        echo "添加员工成功";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}

// 处理添加求职者的请求
if ($_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST["add_applicant"])) {
    $name = $_POST["name"];
    $email = $_POST["email"];
    $position = $_POST["position"];
    $resume = $_POST["resume"];

    // 插入记录到求职者表
    $sql = "INSERT INTO applicants (name, email, position, resume) VALUES ('$name', '$email', '$position', '$resume')";
    if ($conn->query($sql) === TRUE) {
        echo "添加求职者成功";
    } else {
        echo "Error: " . $sql . "<br>" . $conn->error;
    }
}
?>

Recruitment management page

The following is a sample code for a simple recruitment management page:

<!DOCTYPE html>
<html>
<head>
    <title>招聘管理</title>
</head>
<body>
    <h1>招聘管理</h1>

    <h2>添加员工</h2>
    <form method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
        <input type="text" name="name" placeholder="姓名" required>
        <input type="email" name="email" placeholder="电子邮箱" required>
        <input type="text" name="position" placeholder="职位" required>
        <button type="submit" name="add_employee">添加员工</button>
    </form>

    <h2>添加求职者</h2>
    <form method="POST" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
        <input type="text" name="name" placeholder="姓名" required>
        <input type="email" name="email" placeholder="电子邮箱" required>
        <input type="text" name="position" placeholder="期望职位" required>
        <textarea name="resume" placeholder="简历" required></textarea>
        <button type="submit" name="add_applicant">添加求职者</button>
    </form>
</body>
</html>

Through the above steps, we have established A simple HR management and recruitment system that adds employee and applicant records and saves them to a database. Of course, this is just a simple example, and a real human resources management system may require more functions and pages.

Summary

This article briefly introduces how to use PHP to develop a simple human resources management and recruitment system. We learned how to create a database, connect to the database, and add employee and applicant records. Of course, the actual system may require more functions, such as viewing and editing records. I hope this article will be helpful to you in the process of learning PHP.
