How to Create a Task Reminder System in PHP?

Often, you find yourself swamped with tasks to take care of, deadlines to fulfill, and the room for error is next to none. Any oversight can lead to missed opportunities, strained relationships, and a significant dent in productivity. Well, the solution is simple, a reliable reminder system.

A good reminder system will notify you of any upcoming tasks, deadlines, or payment schedules, so your work is streamlined. Through this blog, I’ll explain how web development experts create a task reminder system in PHP.

We have created a demo project and displayed the code excerpts for different parts of the system. Refer to the Github source codes for a basic idea. Let’s get straight into it.

Features to Include in a Task Reminder System

A task reminder system is designed to manage tasks and remind users of pending and completed activities. At a high level, there are some key features a reminder system should have:

• User Authentication (Login & Registration)
• Task Management (Create, Update, Delete, and View Tasks)
• Task Status Updates (Pending, Completed)
• Reminder Notifications (For upcoming deadlines)
• User Dashboard (Overview of tasks)

The main goal of the system is to allow users to manage their tasks effectively, keep track of deadlines, and receive notifications about important tasks. So keep this in consideration when creating the system.

Prerequisites for Creating a Task Reminder System in PHP

Before you start the development, there are a few system requirements and technologies you need to take care of. Here are the following.

• PHP: One of the best server-side scripting languages. It will handle the logic for user registration, login, task creation, and notifications.
• MySQL Database: The database will store user data and task-related information.
• HTML/CSS/JavaScript: For building the front end and creating a dynamic user experience.
• AJAX (Optional): For asynchronous data handling (e.g., fetching tasks without reloading the page).
• Browser Storage (Optional): To store reminder notifications.

After you have taken care of these, it’s time to create the reminder system. Mind you, the requirements listed above are for a basic system.

How to Create a Task Reminder System in PHP?

At this point, we assume all of the prerequisites have been taken care of. The process starts with the implementation of key features.

Implement the Key Features

We’ll look at the features one-by-one and see how they are implemented.

User Authentication (Login & Registration)

The first step in the system is user registration and login. Users need to create an account and authenticate themselves before interacting with the system.

• Registration Page: Collects basic user information (e.g., username, email, password) and stores it in the database.
• Login Page: Verifies user credentials and grants access to the system.
• Session Management: PHP sessions are used to maintain the logged-in state and track user activity.

Security Consideration: Ensure that passwords are stored securely using password hashing (e.g., password_hash() in PHP).

Task Management (CRUD Operations)

Once a user is logged in, they can interact with tasks. The core functionality for task management includes Create, Read, Update, and Delete (CRUD).

• Create Task: Users can add a new task with details such as title, description, deadline, and priority.
• View Tasks: Users can see all tasks listed on their dashboard, organized by completion status (Pending/Completed).
• Update Task: Users can update the status of tasks (e.g., mark a task as completed).
• Delete Task: Users can delete tasks they no longer need.

This part of the process ensures users are able to manage their own tasks.

Task Status

Managing task status is essential. Each task can have the following states:

• Pending: The task is not yet completed and is awaiting attention.
• Completed: The task has been finished.

Tasks can be marked as completed by the user or automatically based on predefined deadlines.

Task Notifications

Notifications are a crucial feature in task reminder systems. After a task is created, the system will notify the user when the deadline is approaching. You can implement JavaScript pop-up notifications or send email notifications for reminders.

In PHP, you can use strtotime() to calculate task deadlines and set reminders. These reminders can be sent via the browser (using JavaScript) or email.

Dashboard (User Overview)

After logging in, users will be redirected to their dashboard, where they can see an overview of their tasks.

The dashboard will display:

• List of Pending Tasks: Tasks that are yet to be completed.
• List of Completed Tasks: Tasks that the user has marked as completed.
• Task Statistics: A summary of how many tasks are pending, completed, or overdue.

The dashboard serves as the central hub for task management, offering a clear overview of everything the user needs to do.

For all of these features, we have provided a GitHub library with the code excerpts. You can implement them and enjoy a basic task reminder system.

Design the Database

A well-structured database is the foundation of your task reminder system. This is where all the information will be stored. Here’s a simple structure of the database for the task reminder system:

Table for Users

This table stores user information such as username, email, password (hashed), and other relevant details.

• user_id (Primary Key)
• username
• email
• password (hashed)

Table for Tasks

This table stores information about tasks assigned to the users.

• task_id (Primary Key)
• user_id (Foreign Key, references Users)
• title
• description
• deadline
• status (Pending/Completed)

You may also want to store additional information, such as priority or reminder times.

Design the User Interface

The user interface (UI) should be simple and intuitive. It should be designed in such a way that users can easily create tasks, view them, and update their statuses.

Pages

There are a few pages to consider and include in your task reminder system.

• Home Page: A welcoming page with links to register or log in.
• Registration Page: Where users can sign up for the system.
• Login Page: Where users log into the system.
• Dashboard: The main area where users can see and manage their tasks.
• Task Management Page: Allows users to create and manage tasks (CRUD operations).
• Logout: A button to log the user out of the system.

Styling

A clean, minimalistic design with easy-to-read fonts and sufficient spacing can greatly improve the user experience. You can achieve this with CSS frameworks like Bootstrap or by writing custom styles.

Handle the Task Reminders

Reminders are essential for any task reminder system. Here’s how you can implement reminders:

• User-defined Reminders: When a user creates a task, they should be able to define a reminder date and time (e.g., 1 hour before the task’s deadline).
• Automatic Reminders: PHP can periodically check the database for tasks whose deadlines are approaching and send reminders either via email or in-app notifications.

For in-app reminders, JavaScript can be used to trigger pop-ups or notifications when the task deadline is near.

Take Care of the Security Considerations

When building a task reminder system, security is paramount. Here are some key areas to consider:

• Password Protection: Never store plain-text passwords. Use PHP’s password_hash() and password_verify() functions to securely store and check passwords.
• Session Management: Make sure sessions are properly handled to prevent unauthorized access.
• Input Validation: Always validate and sanitize user input to prevent SQL injection or XSS attacks.
• Secure Database: Ensure your database is securely configured and that only authorized users can modify data.

With these practices, you can significantly reduce the risk of attacks on your PHP task reminder system.

Prepare for Future Enhancements

Once the basic system is in place, you can enhance the Task Reminder System by adding advanced features:

• Recurring Tasks: Allow users to set tasks that repeat at regular intervals (e.g., daily, weekly).
• Priority Levels: Add different priority levels (Low, Medium, High) to tasks.
• Task Categories: Group tasks into categories (e.g., Work, Personal, Shopping).
• Email Reminders: Send email notifications to users when a task’s deadline is approaching.
• API Integration: Build an API to allow users to interact with the system programmatically (e.g., through a mobile app).

Try to create a task reminder that is not only functional today but also adaptable to future challenges and opportunities.

For more advanced functionalities, our Reminder System will be more suitable.
