How to use Laravel to develop an online music platform

Introduction:
With the rapid development of the Internet, online music platforms have become the main channel for people to obtain music. In this article, we will explore how to use the Laravel framework to develop a powerful online music platform. We'll walk through the required steps and code examples in detail.

1. Preparation
   First, we need to install and set up the Laravel framework. Laravel can be installed through Composer:

composer global require laravel/installer

Then you can create a new Laravel project using the following command:

laravel new music_platform

2. Database Settings
   Before starting, we need Set up the database connection. In Laravel, this can be configured in the .env file. You can choose MySQL, SQLite or other database drivers according to your needs. The sample configuration is as follows:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=music_platform
DB_USERNAME=root
DB_PASSWORD=

and run the following commands in the terminal to generate the database migration and data filling files:

php artisan make:migration create_music_table --create=music
php artisan make:seeder MusicSeeder

In the create_music_table migration file, you can Define the fields of the music table. The sample code is as follows:

public function up()
{
    Schema::create('music', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->string('artist');
        $table->string('album');
        $table->string('genre');
        $table->integer('year');
        $table->timestamps();
    });
}

Then, in the MusicSeeder filling file, you can fill in a sample music data. The sample code is as follows:

public function run()
{
    DB::table('music')->insert([
        'title'  => 'Sample Song',
        'artist' => 'Sample Artist',
        'album'  => 'Sample Album',
        'genre'  => 'Sample Genre',
        'year'   => 2021,
    ]);
}

Finally , run the following commands in the terminal to perform migrations and populate the database:

php artisan migrate
php artisan db:seed

3. Create models and controllers
   In Laravel, you can use the following commands to create models and controllers:

php artisan make:model Music
php artisan make:controller MusicController --resource

In the Music model, you can define the Eloquent model corresponding to the music table. The sample code is as follows:

protected $table = 'music';

In the MusicController controller, The functions of getting a music list, adding music, and deleting music can be implemented. The sample code is as follows:

public function index()
{
    $music = Music::all();
    return view('music.index', ['music' => $music]);
}

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

public function store(Request $request)
{
    $this->validate($request, [
        'title'  => 'required',
        'artist' => 'required',
        'album'  => 'required',
        'genre'  => 'required',
        'year'   => 'required|integer',
    ]);

    Music::create($request->all());

    return redirect()->route('music.index')->with('success', 'Music added successfully');
}

public function destroy(Music $music)
{
    $music->delete();

    return redirect()->route('music.index')->with('success', 'Music deleted successfully');
}

4. Create a view
   In Laravel, you can use the Blade template engine to create a view. First, create a music list viewindex.blade.php, the sample code is as follows:

@foreach($music as $item)
    <p>{{$item->title}} - {{$item->artist}}</p>
@endforeach

Then, create a view to add musiccreate.blade.php, the sample code is as follows:

<form action="{{route('music.store')}}" method="POST">
    @csrf
    <input type="text" name="title" placeholder="Title" required>
    <input type="text" name="artist" placeholder="Artist" required>
    <input type="text" name="album" placeholder="Album" required>
    <input type="text" name="genre" placeholder="Genre" required>
    <input type="text" name="year" placeholder="Year" required>
    <button type="submit">Add Music</button>
</form>

5. Routing settings
   In Laravel, routing can be set in the routes/web.php file. The sample code is as follows:

Route::resource('music', 'MusicController');

6. Run the application
   Run the following command to start the Laravel development server:

php artisan serve

Finally, visit # in the browser ##http://localhost:8000/music, you can view the music list and add new music through http://localhost:8000/music/create.
