Introduction
This project aims to create a simple, user-friendly crowdfunding platform where users can create and
support campaigns. Users can view a list of campaigns, donate to them, and view their donation
history through a personalized dashboard.
Functional Overview
The platform consists of the following key features:
● User Registration and Authentication: Users can sign up, log in, and access their profiles.
● Campaigns: Users can view campaigns with details such as the goal, funds raised, and days
remaining.
● Support/Donation: Users can donate money to a campaign and select a reward tier based on
their donation amount.
● Dashboard: Users can view their donation history, the campaigns they've supported, and the
total amount donated.
● Admin Panel (Optional): Manage campaigns, user accounts, and donations (not
implemented in the current version).
System Architecture
The project is based on the classic three-tier architecture:
1. Presentation Layer: HTML, CSS, and JavaScript (frontend).
2. Application Layer: PHP (server-side scripting).
3. Data Layer: MySQL (database management).

ER Diagram
Here is the Entity-Relationship (ER) diagram that outlines the structure of the database for the
● Users Table: Contains information about each user registered on the platform.
● Campaigns Table: Stores data about crowdfunding campaigns such as the goal, raised
amount, and campaign details.
● Support Table: Links users to the campaigns they have donated to, including the amount
donated and the time of the donation.

Database Schema
Here are the table definitions for the three main entities in the system:
Users Table
CREATE TABLE users (
id INT AUTO_INCREMENT PRIMARY KEY,
first_name VARCHAR(50) NOT NULL,
last_name VARCHAR(50) NOT NULL,
email VARCHAR(100) NOT NULL UNIQUE,
password VARCHAR(255) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
Campaigns Table
CREATE TABLE campaigns (
id INT AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(255) NOT NULL,
description TEXT NOT NULL,
goal DECIMAL(10, 2) NOT NULL,
raised_amount DECIMAL(10, 2) DEFAULT 0,
location VARCHAR(100),
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Support Table
CREATE TABLE support (
id INT AUTO_INCREMENT PRIMARY KEY,
user_id INT NOT NULL,
campaign_id INT NOT NULL,
amount DECIMAL(10, 2) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (user_id) REFERENCES users(id),
FOREIGN KEY (campaign_id) REFERENCES campaigns(id)
);
Implementation Details
● Sign-In and Sign-Up
The signin.php script allows users to authenticate with their email and password. Once validated,
the user is redirected to their dashboard.
$sql = "SELECT * FROM users WHERE email = ?";
$stmt = $conn->prepare($sql);
$stmt->bind_param("s", $email);
$stmt->execute();
$result = $stmt->get_result();

● Dashboard
The dashboard displays the user’s information, along with the campaigns they have supported and
how much they have donated to each.
$sql = "
SELECT support.campaign_id, support.amount, campaigns.title,
campaigns.goal, campaigns.raised_amount
FROM support
JOIN campaigns ON support.campaign_id = campaigns.id
WHERE support.user_id = ?";

● Campaign Details and Donations
Each campaign shows a progress bar for the funds raised. Users can donate by selecting a reward tier
and entering a custom donation amount.
$sql = "INSERT INTO support (user_id, campaign_id, amount) VALUES
(?, ?, ?)";
$stmt = $conn->prepare($sql);
$stmt->bind_param("iid", $user_id, $campaign_id, $amount);

Conclusion:
This project provides a fundamental platform for crowdfunding, enabling users to create and support
campaigns with ease. The system features user authentication, campaign creation, and a donation
tracking mechanism.
Future Enhancements
Some of the planned future features include:
● Search and Filter for Campaigns: Allow users to search for specific campaigns or filter
based on categories.
● Admin Dashboard: Add a panel for administrators to manage campaigns and users.
● Email Notifications: Send email alerts to users when campaigns they’ve supported reach
certain milestones.
● Payment Gateway Integration: Instead of dummy payment inputs, integrate with real-world
payment systems like PayPal or Stripe.
● Enhanced Security: Implement more robust password hashing techniques and secure session
management.
