Welcome to the Online Marketplace backend! This project is a simple yet powerful backend system for an online marketplace where users can buy and sell products. It features user registration, product management, and integrated Stripe payment processing.

• User registration and authentication
• Product listing and management
• Stripe payment integration for secure transactions
• Basic routing and request handling

Before you begin, ensure you have met the following requirements:

• PHP installed on your server (>= 7.2)
• MySQL database
• Composer for dependency management
• A Stripe account for payment processing

Follow these steps to set up the project locally:

1. Clone the repository:

   git clone https://github.com/bartzalewski/marketplace.git

2. Navigate to the project directory:

   cd marketplace

3. Install dependencies using Composer:

   composer install

4. Create a MySQL database and import the provided SQL file:

   CREATE DATABASE marketplace;
   USE marketplace;
   
   CREATE TABLE users (
       id INT AUTO_INCREMENT PRIMARY KEY,
       username VARCHAR(50) NOT NULL,
       email VARCHAR(100) NOT NULL,
       password VARCHAR(255) NOT NULL
   );
   
   CREATE TABLE products (
       id INT AUTO_INCREMENT PRIMARY KEY,
       user_id INT,
       name VARCHAR(100) NOT NULL,
       description TEXT,
       price DECIMAL(10, 2) NOT NULL,
       FOREIGN KEY (user_id) REFERENCES users(id)
   );
   
   CREATE TABLE transactions (
       id INT AUTO_INCREMENT PRIMARY KEY,
       product_id INT,
       user_id INT,
       stripe_charge_id VARCHAR(100),
       amount DECIMAL(10, 2),
       created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
       FOREIGN KEY (product_id) REFERENCES products(id),
       FOREIGN KEY (user_id) REFERENCES users(id)
   );

5. Configure the project by editing the src/config.php file with your database and Stripe credentials:

   <?php
   // src/config.php
   return [
       'db' => [
           'host' => '127.0.0.1',
           'dbname' => 'marketplace',
           'user' => 'your_db_user',
           'password' => 'your_db_password',
       ],
       'stripe' => [
           'secret_key' => 'your_stripe_secret_key',
           'publishable_key' => 'your_stripe_publishable_key',
       ]
   ];

6. Start the PHP built-in server:

   php -S localhost:8000 -t public
