How Does the Employee Leave Management System Work?

The system allows employees to submit leave applications and track their status, while administrators manage employee records and process leave requests. The dashboard displays important statistics about pending, approved, and declined applications.

PHP processes application requests and communicates with MySQL to store and retrieve information. Employees and administrators access the functions available to their respective roles through the web interface.

What Features Are Available in the Employee Leave Management System?

The project includes employee registration and login, administrator login, dashboard statistics, department and employee management, leave type configuration, leave applications, approval workflows, leave history, administrator management, and password recovery.

1. Employee Registration and Login

Employees can register and log in to access the application. Authentication helps restrict access to authorized accounts and provides access to employee-specific functions.

2. Admin Login

Administrators have a separate login panel for managing departments, employees, leave types, applications, and other administrative functions.

3. Dashboard Statistics

The dashboard displays an overview of pending, approved, and declined leave applications. These statistics help administrators monitor the status of leave requests.

4. Department Management

Administrators can add, edit, and delete department records to keep organizational information organized and up to date.

5. Employee Management

The employee management module allows administrators to create, update, and remove employee records, including names, roles, and login details.

6. Leave Types Management

Administrators can define different leave categories, such as sick leave and casual leave, according to organizational requirements.

7. Apply for Leave

Employees can submit leave applications by providing details such as leave dates, leave type, and reason. This makes the application process easier to manage digitally.

8. Leave Approval and Decline

Administrators can review submitted requests and approve or decline them, or keep them pending for further review. This creates a structured leave approval workflow.

9. Leave History

Employees and administrators can track leave application histories and review whether requests are pending, approved, or declined.

10. Admin Management

The system allows administrators to add or remove administrator accounts, helping distribute leave management responsibilities among authorized staff.

11. Password Recovery

The password recovery feature helps users regain access when they forget their login credentials. The exact recovery workflow depends on the implementation supplied with the project.

How to Install the Employee Leave Management System in VS Code?

You can run the project locally using XAMPP, Visual Studio Code, and a web browser. The installation process involves extracting the project, importing its database, and checking the database connection settings.

Step 1: Install the Required Software

Install the following tools before starting:

• XAMPP Server for Apache and MySQL.
• Visual Studio Code for editing project files.
• Web Browser

Step 2: Extract the Project Files

Extract EmployeeLeaveSystem.zip into the XAMPP htdocs directory. The example folder path is:

C:\xampp\htdocs\EmployeeLeaveSystem

Step 3: Start Apache and MySQL

Open the XAMPP Control Panel and start Apache and MySQL. Both services must be running to access the PHP application and its database.

Step 4: Create and Import the Database

Open phpMyAdmin at the following local address:

http://localhost/phpmyadmin

Create a database named employeeleavedb. You can also create it by executing:

CREATE DATABASE employeeleavedb;

Import the SQL file provided with the project from:

EmployeeLeaveSystem/DATABASE FILE/employeeleavedb.sql

Step 5: Configure the Database Connection

Locate the database connection file, usually named config.php or stored within the admin folder. Verify that the connection settings match your local MySQL configuration.

<?php
$servername = "localhost";
$username   = "root";
$password   = "";
$database   = "employeeleavedb";

$conn = mysqli_connect(
    $servername,
    $username,
    $password,
    $database
);

if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
?>

Step 6: Run the Project

Open your browser and visit the following local URL, assuming the extracted folder is named EmployeeLeaveSystem:

http://localhost/EmployeeLeaveSystem/

If the database configuration and project files are correct, the application should open locally.
