How to set up laravel background

As a popular PHP framework, Laravel is naturally suitable for developing backend systems. Before using Laravel to develop the backend system, we need to understand some necessary basic settings. This article will introduce you to how to set up the Laravel backend system.

1. Installing Laravel
   Before starting the setup of the Laravel backend system, we need to install Laravel first. On the official Laravel website, you can find detailed installation instructions. After installing Laravel, we can start setting it up.
2. Configuring the database
   Laravel uses the .env configuration file to store the environment variables needed by the program, including database-related information. In the .env file, we need to configure the database type, address, port, database name, user name and password, etc. For example:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=mydatabase
DB_USERNAME=myusername
DB_PASSWORD=mypassword

3. Enable Laravel's debugging mode
   During the development process, we need to find and solve errors as much as possible. To do this, we need to set Laravel into debug mode. In the development environment, we only need to set the APP_DEBUG variable in the .env file to true to enable debugging mode:

APP_DEBUG=true

4. Configuring Laravel's background Management system
   Laravel does not have a built-in backend management system, but we can use third-party packages to quickly build a backend system. Laravel-admin is a popular backend management system that provides relatively complete backend management functions and flexible custom configuration. We can install Laravel-admin through the Composer package management tool:

composer require encore/laravel-admin

After successful installation, we need to register the service provider and resource files . Add the following configuration in the config/app.php file:

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

'aliases' => [
// ...
'Admin' => EncoreAdminFacadesAdmin::class,
],

Finally, run the following command on the command line You can publish the resource file of Laravel-admin:

php artisan vendor:publish --provider="EncoreAdminAdminServiceProvider"

5. Login and authentication
   When we install the background management Once the system is installed, the next step is to configure login and authentication. We can use Laravel's own authentication system to achieve this. Add the following routes in the routes/web.php file:

Auth::routes();

This will automatically generate a set of login, registration, and logout routes. Next, we need to create a users table to store user information. Run the following command on the command line:

php artisan make:model User -m

To create a column for the user, open the In the generated database migration file, add the following code:

Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')-> nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});

Run the migration command to create the users table:

php artisan migrate

Now our user table is ready. Next, we need to create a user controller to manage background user information. Run the following command:

php artisan make:controller UserController

In UserController, we need to define some methods for user management:

class UserController extends Controller
{
public function index()
{

// TODO: 显示用户列表

}

public function create()
{

// TODO: 创建用户

}

public function store(Request $request)
{

// TODO: 保存用户信息

}

public function edit($id)
{

// TODO: 显示编辑用户页面

}

public function update(Request $request, $id)
{

// TODO: 更新用户信息

}

public function destroy($id)
{

// TODO: 删除用户

}
}

Finally, add the following code to the routes/web.php file to register user management-related routes into the system:

Route::resource('users', 'UserController' );

Now, we have completed the setup of the Laravel backend system. Through Laravel-admin, we can quickly build a fully functional backend management system, and through the powerful functions of Laravel, we can easily implement functions such as adding, deleting, modifying, and checking data, form verification, and file uploading.
