PHP e-commerce system development: expansion and maintenance

In terms of expanding e-commerce systems, common methods include adding new modules and integrating third-party APIs. Maintaining the system requires performing security updates, creating database backups, and monitoring system performance.

PHP e-commerce system development: expansion and maintenance

Expand your e-commerce system

As your business grows, you may E-commerce systems need to be expanded to meet changing needs. Here are some common scaling methods:

tail -f /var/log/apache2/error.log

Practical Example: Extending Product Pages

To show extensions in action, let’s create a custom product page module:

// 创建模块类
class ProductPageModule extends Module
{
    // 安装模块
    public function install()
    {
        // 创建数据库表
        $this->installDb();

        // 注册模版钩子
        $this->registerHook('ProductPage');
    }

    // 卸载模块
    public function uninstall()
    {
        // 删除数据库表
        $this->uninstallDb();

        // 取消注册模版钩子
        $this->unregisterHook('ProductPage');
    }

    // 模版钩子函数
    public function hookProductPage($params)
    {
        // 从数据库获取自定义数据
        $custom_data = $this->getCustomData($params['product_id']);

        // 在模版中显示自定义数据
        $this->display('custom_product_data', ['data' => $custom_data]);
    }
}
