How to use Laravel to develop an online ordering system based on WeChat official accounts

With the widespread use of WeChat official accounts, more and more companies are beginning to use them As an important channel for online marketing. In the catering industry, developing an online ordering system based on WeChat public accounts can improve the efficiency and sales of enterprises. This article will introduce how to use the Laravel framework to develop such a system and provide specific code examples.

  1. Project preparation
    First, you need to ensure that the Laravel framework has been installed in the local environment. You can download the latest version by visiting the Laravel official website (https://laravel.com). Once downloaded and installed, you can create a new Laravel project by running the following command:
composer create-project --prefer-dist laravel/laravel project-name
Copy after login
  1. Create Database
    In the root directory of your Laravel project, open . env file and configure the database. After configuring the relevant information of the database, run the following command to generate the database migration file:
php artisan make:migration create_menu_table --create=menu
Copy after login

Then, define the structure of the menu table in the generated migration file, for example:

public function up()
{
    Schema::create('menu', function (Blueprint $table) {
        $table->increments('id');
        $table->string('name');
        $table->text('description');
        $table->double('price', 8, 2);
        $table->timestamps();
    });
}
Copy after login

Finally, run the following command to perform database migration:

php artisan migrate
Copy after login
  1. Create models and controllers
    In Laravel, you can use Artisan commands to quickly generate models and controllers. Run the following commands to generate the Menu model and MenuController controller:
php artisan make:model Menu -m
php artisan make:controller MenuController --resource
Copy after login

Define the relationship between the menu table and the model in the generated model class:

public function getMenus()
{
    return $this->hasMany(Menu::class);
}
Copy after login

In the controller class Implement various operation methods, such as:

public function index()
{
    $menus = Menu::all();
    return view('menu.index', compact('menus'));
}

public function create()
{
    return view('menu.create');
}

public function store(Request $request)
{
    Menu::create($request->all());
    return redirect()->route('menu.index')->with('success', '菜单添加成功!');
}
Copy after login
  1. Create a view
    Create a menu directory in the resources/views directory and create the corresponding view file in the directory. For example, you can create an index.blade.php view file to display the menu list:
<table>
    <tr>
        <th>菜单名称</th>
        <th>菜单描述</th>
        <th>菜单价格</th>
    </tr>
    @foreach ($menus as $menu)
        <tr>
            <td>{{ $menu->name }}</td>
            <td>{{ $menu->description }}</td>
            <td>{{ $menu->price }}</td>
        </tr>
    @endforeach
</table>
Copy after login
  1. Configuring routing
    Define routing rules in the routes/web.php file, for example:
Route::resource('menu', 'MenuController');
Copy after login
  1. Connect to the WeChat public account
    Use the laravel-wechat extension package in the Laravel framework to interact with the WeChat public account. Run the following command in the Laravel project to install the extension package:
composer require "overtrue/laravel-wechat:~4.0"
Copy after login

Then, add the ServiceProvider and Facade configuration in the config/app.php file:

'providers' => [
    // ...
    OvertrueLaravelWeChatServiceProvider::class,
],

'aliases' => [
    // ...
    'WeChat' => OvertrueLaravelWeChatFacade::class,
],
Copy after login

Next, run The following commands are used to generate configuration files and routing rules:

php artisan vendor:publish --provider="OvertrueLaravelWeChatServiceProvider"
Copy after login

Open the config/wechat.php file and modify the corresponding parameters according to your own configuration. Then, add the relevant routing rules of the WeChat official account in the routes/web.php file, for example:

Route::any('/wechat', 'WeChatController@serve');
Copy after login
  1. Create a WeChatController controller
    Run the following command to generate a WeChatController controller:
php artisan make:controller WeChatController
Copy after login

In the generated controller class, use the functions provided by the WeChat extension package to handle various interaction logics of WeChat. For example:

use WeChat;

public function serve()
{
    $wechat = app('wechat');
    $wechat->server->setMessageHandler(function($message){
        if ($message->MsgType == 'text' && $message->Content == '菜单') {
            $menus = Menu::all();
            $content = '菜单列表:';
            foreach ($menus as $menu) {
                $content .= $menu->name . ' - ¥' . $menu->price . "
";
                $content .= $menu->description . "

";
            }
            return $content;
        }
    });
    return $wechat->server->serve();
}
Copy after login
  1. Test
    Start the development server and run the following command:
php artisan serve
Copy after login

Then, enter http:// in the browser address bar localhost:8000/menu to access the ordering system.

Finally, configure the URL of the WeChat public account to http://your-domain.com/wechat, and make relevant settings on the WeChat public platform, and you can send it via WeChat instructions to access the online ordering system.

Summary
This article introduces how to use the Laravel framework to develop an online ordering system based on WeChat public accounts. Through the above steps, we can quickly build a system with menu management functions and interact with WeChat. Of course, during the actual development process, the system’s functions and user experience can be further improved, such as adding user order management and payment functions. I hope this article can be helpful to you in developing WeChat public account-related functions.
