With the rise of e-commerce, the global logistics industry is in full swing. For consumers, it is extremely important to be able to understand logistics information in a timely manner, while for e-commerce companies, a good logistics tracking system is needed to better manage collection, transportation and delivery. This article will introduce how to use ThinkPHP6 for logistics tracking operations.

1. Introduction to ThinkPHP6

ThinkPHP is a comprehensive and efficient PHP framework that has been widely used and recognized. ThinkPHP6 is the latest version, which has many advantages such as modularization, annotation routing, dependency injection, etc., and can help developers quickly build web applications.

2. Logistics tracking system design

1. Module design

According to the business process of logistics tracking, the logistics tracking system can be divided into the following modules:

• User module: registration, login, password change and other functions.
• Logistics module: including logistics company information, waybill information, etc.
• Freight module: Calculate freight based on cargo weight, type, distance and other parameters.
• Order module: including ordering, payment, cancellation, inquiry and other functions.
• Complaint module: handle user complaints about logistics services.
• Administrator module: Query orders, logistics information, handle complaints and other functions.

2. Technology selection

• Framework: ThinkPHP6
• Database: MySQL
• Cache: Redis
• Message queue: RabbitMQ

3. Specific implementation of logistics tracking system

1. Install ThinkPHP6

Install ThinkPHP6 locally or on the server. For specific steps, please refer to ThinkPHP Official documentation.

2. Create database and data tables

Create a database containing user, logistics, order and other data tables, and design the table structure respectively. In ThinkPHP6, you can use the database migration tool Migrate to create and manage database tables. Use the following command in Terminal to enable Migrate:

php think migrate:run

3. Write the model

Model (Model) is a database operation At the core, the model in ThinkPHP6 inherits from the BaseModel class, which can simplify the addition, deletion, modification and query operations of data tables. For example, the following is a sample code for order model design:

namespace appcommonmodel;

use thinkModel;

class Order extends Model
{
    protected $table = 'order';

    // 关联用户模型
    public function user()
    {
        return $this->belongsTo('User');
    }

    // 关联物流模型
    public function express()
    {
        return $this->belongsTo('Express');
    }

    // 查询订单列表
    public function getOrderList()
    {
        $orderList = $this->with(['user','express'])->paginate(5);
        return $orderList;
    }

    // 查询订单详情
    public function getOrderDetail($orderId)
    {
        $orderDetail = $this->with(['user','express'])->find($orderId);
        return $orderDetail;
    }
}

4. Write the controller

The controller (Controller) is the core of the web application and is responsible for receiving requests and calling the corresponding model. deal with. The following is a sample code for order controller design:

namespace appindexcontroller;

use thinkController;
use appcommonmodelOrder as OrderModel;

class Order extends Controller
{
    // 查询订单列表
    public function getOrderList()
    {
        $orderModel = new OrderModel();
        $orderList = $orderModel->getOrderList();
        return $this->fetch('order_list', ['orderList' => $orderList]);
    }

    // 查询订单详情
    public function getOrderDetail($orderId)
    {
        $orderModel = new OrderModel();
        $orderDetail = $orderModel->getOrderDetail($orderId);
        return $this->fetch('order_detail', ['orderDetail' => $orderDetail]);
    }
}

5. Write a view file

The view file (View) is the user interface of the web application, using front-end technologies such as HTML and CSS. The following is a sample code for order list view design: "

{extend name="layout"}
{block name="content"}
订单列表

        {foreach $orderList as $order}
        
        {/foreach}
    

    

        

            
订单号
            
用户
            
物流公司
            
运单号
            
操作
        
    
    

            
{$order.order_no}
            
{$order.user.username}
            
{$order.express.express_name}
            
{$order.waybill_no}
            

                详情
            
        

{/block}

The layout and url functions involved in the above view files need to be configured in advance to ensure the normal operation of the system.

6. Test and Deployment

After writing the code, you need to test and deploy it. You can use the built-in web server provided by ThinkPHP6 for testing. Use the following command to start the web server:

php think run

If there is no problem, you can deploy the program to the production environment.

4. Summary

This article introduces how to use ThinkPHP6 for logistics tracking operations. By creating model, controller and view files, and associating and querying various data tables, The basic functions of the logistics tracking system. Of course, the actual logistics tracking system is much more complex than this and requires more technology and knowledge. However, the ideas and methods provided in this article can provide a reference for the implementation of more complex logistics tracking systems. And learn from it.
