Sistema Multitienda en Línea PHP y MySQL

Introduction

This tutorial will guide you through the process of creating a multi-store online system using PHP and MySQL. This platform allows different stores to register, publish their products, and manage various functionalities through an administrative environment. By the end of this guide, you will have a better understanding of how to set up and manage such a system.

Step 1: Setting Up Your Development Environment

To begin developing your multi-store system, you need to set up your local development environment.

• Install XAMPP or WAMP: These software packages allow you to run PHP and MySQL on your local machine.
• Create a Database:
  • Open phpMyAdmin from your XAMPP or WAMP control panel.
  • Create a new database (e.g., multistore_db).

Step 2: Designing the Database Schema

A well-structured database schema is crucial for your application.

• Create Tables: You will need to create the following tables:

  • Users: Store user details.
  • Stores: Store information about different stores.
  • Products: Keep track of products offered by each store.
  • Orders: Manage customer orders.

• Example SQL for Tables:

  CREATE TABLE users (
      id INT AUTO_INCREMENT PRIMARY KEY,
      username VARCHAR(50) NOT NULL,
      password VARCHAR(255) NOT NULL
  );
  
  CREATE TABLE stores (
      id INT AUTO_INCREMENT PRIMARY KEY,
      name VARCHAR(100) NOT NULL,
      owner_id INT,
      FOREIGN KEY (owner_id) REFERENCES users(id)
  );
  
  CREATE TABLE products (
      id INT AUTO_INCREMENT PRIMARY KEY,
      name VARCHAR(100) NOT NULL,
      store_id INT,
      price DECIMAL(10, 2) NOT NULL,
      FOREIGN KEY (store_id) REFERENCES stores(id)
  );
  

Step 3: Creating the User Registration and Login System

Implement user authentication to allow stores to register and log in.

• Registration Form: Create a form where users can input their details.
• Password Hashing: Use PHP's password_hash() function to securely store passwords.
• Login Logic: Verify user credentials on login using password_verify().

Step 4: Building the Store Management Interface

Develop an administrative interface for managing stores and products.

• Store Registration: Allow users to register their stores.

• Product Addition: Create a form for adding products linked to the respective store.

• Example Code for Adding Products:

  if ($_SERVER['REQUEST_METHOD'] == 'POST') {
      $name = $_POST['product_name'];
      $store_id = $_SESSION['store_id']; // Get from session after login
      $price = $_POST['product_price'];
  
      $stmt = $pdo->prepare("INSERT INTO products (name, store_id, price) VALUES (?, ?, ?)");
      $stmt->execute([$name, $store_id, $price]);
  }
  

Step 5: Implementing the Customer Ordering System

Allow end-users to browse and order products from various stores.

• Product Listing Page: Display products from all registered stores.
• Order Form: Create a form for customers to place orders.

Conclusion

In this tutorial, you learned how to create a multi-store online system using PHP and MySQL. Key steps included setting up your development environment, designing the database schema, creating user authentication, building the store management interface, and implementing an ordering system.

For further development, consider adding features like product reviews, payment gateways, or an advanced search functionality to enhance user experience.
