How to use PHP and Typecho to build an e-commerce platform

Typecho is a simple, lightweight open source PHP framework, suitable for building various types of websites, including e-commerce platforms. In this article, we will introduce how to use PHP and Typecho to build a basic e-commerce platform, and provide you with some code examples.

1. Preparation
   Before you begin, make sure you have installed a PHP environment and have downloaded and installed the latest Typecho program. You can download it from Typecho’s official website and follow the official installation instructions to install it.
2. Configuring Database
   Typecho uses MySQL as the backend database, so before starting, you need to create a new database and configure Typecho to connect to this database. In the Typecho installation directory, you will find a file named "config.inc.php". Open this file and find the following lines of code in the file:

/** 数据库用户名 */
define('__TYPECHO_DB_USER__', 'root');

/** 数据库密码 */
define('__TYPECHO_DB_PASSWORD__', '');

/** 数据库主机 */
define('__TYPECHO_DB_HOST__', 'localhost');

/** 数据库名称 */
define('__TYPECHO_DB_NAME__', 'typecho');

/** 数据库类型 */
define('__TYPECHO_DATABASE_TYPE__', 'mysql');

Modify the values ​​of these parameters to the correct values ​​based on your database configuration.

3. Create product table
   In order to store product information, we need to create a new table in the database. You can use the following SQL statement to create a table named "products":

CREATE TABLE products (
  id INT(11) AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(255) NOT NULL,
  price DECIMAL(10,2) NOT NULL,
  description TEXT,
  image VARCHAR(255)
);

In the above SQL statement, we created a table that contains product names, prices, descriptions, and pictures.

4. Create a Typecho theme
   Typecho uses themes to manage the look and layout of your website. In order to create an e-commerce platform, we need to customize a theme. In the usr/themes/ directory under the Typecho installation directory, create a new folder as the theme name, such as "ecommerce".

In this folder, create a file named "products.php" and add the following code to the file:

<?php while($this->next()): ?>
  <div class="product">
    <h3><?php $this->title(); ?></h3>
    <p><?php $this->content(); ?></p>
    <p><strong>价格:</strong> <?php $this->fields->price(); ?></p>
    <?php if($this->fields->image): ?>
      <img src="<?php $this->fields->image(); ?>" />
    <?php endif; ?>
  </div>
<?php endwhile; ?>

The above code will display the products title, content, price and images. You can customize it according to your needs.

5. Create product list page
   In order to display the product list, we need to create an independent page in Typecho. In Typecho's backend management interface, click "Appearance" and then click "Page". In the page list, click "New" to create a new page.

In the page editor, enter the following code:

---
title: 商品列表
---

<?php $this->widget('Widget_Contents_Post_Recent', 'pageSize=10&type=page')->to($products); ?>
<?php while($products->next()): ?>
  <div class="product">
    <h3><a href="<?php $products->permalink(); ?>"><?php $products->title(); ?></a></h3>
    <p><?php $products->content(); ?></p>
    <p><strong>价格:</strong> <?php $products->fields->price(); ?></p>
    <?php if($products->fields->image): ?>
      <img src="<?php $products->fields->image(); ?>" />
    <?php endif; ?>
  </div>
<?php endwhile; ?>

6. Create product details page
   In order to display the detailed information of the product, we also need to create it in Typecho A standalone page. In Typecho's backend management interface, click "Appearance" and then click "Page". In the page list, click "New" to create a new page.

In the page editor, enter the following code:

---
title: 商品详情
---

<div class="product">
  <h3><?php $this->title(); ?></h3>
  <p><?php $this->content(); ?></p>
  <p><strong>价格:</strong> <?php $this->fields->price(); ?></p>
  <?php if($this->fields->image): ?>
    <img src="<?php $this->fields->image(); ?>" />
  <?php endif; ?>
</div>

7. Add product
   In the background management interface of Typecho, click "Compose", and then click " Publish" to create a new product. In the product editor, enter the product's title, content, price, and image. After saving the product, you can see the new product on the product list page.
