How to quickly build a website in Laravel (tutorial)

The Laravel framework is a modern PHP framework that provides many useful features, including routing, ORM, template engine, etc. In this article, I will briefly introduce how to use the Laravel framework to quickly and easily create a complete website.

1. Installation and Configuration

Before we begin, we need to make sure that PHP and Composer are installed. In addition, the Laravel framework needs to be installed. The latest Laravel version can be downloaded from the official website. The easiest way to install Laravel is to use Composer. Enter the following command on the command line:

composer global require "laravel/installer"

After the installation is complete, we need to create a new Laravel project. On the command line, go into the directory where we want to create the project and enter the following command:

laravel new myproject

Laravel will create a new project named myproject in that directory. After that, we need to do some basic configuration. In the .env file, we need to modify the database-related configuration items to the values ​​we need.

2. Creating models and database migrations

In Laravel, models are used to represent data tables. We need to create a model and corresponding database migration so that we can easily access the database using the ORM. Enter the following command on the command line:

php artisan make:model Post -m

This will create a model named Post in the app directory, as well as a corresponding database migration. Open the migration file in the database/migrations directory, and you can see how to build the database table structure. You need to modify this file according to your needs. For example:

public function up()
{
    Schema::create('posts', function (Blueprint $table) {
        $table->increments('id');
        $table->string('title');
        $table->text('content');
        $table->timestamps();
    });
}

After completing the database migration, we need to execute the migration command to create a new data table. Enter the following command in the command line:

php artisan migrate

3. Create controller and view

Now we need to create the controller and view so that we can display the data from the Post model . Create a controller using the following command:

php artisan make:controller PostController

This will create a controller named PostController in the app/Http/Controllers directory. You can use the following code to implement the list display and detail display methods in the controller:

public function index()
{
    $posts = Post::all();

    return view('posts.index', ['posts' => $posts]);
}

public function show($id)
{
    $post = Post::find($id);

    return view('posts.show', ['post' => $post]);
}

The easiest way to create a view is to use Laravel's Blade template engine. Create a directory posts in the resources/views directory and create the following two files in it:

index.blade.php

@foreach ($posts as $post)
    <div>
        <h2>{{ $post->title }}</h2>
        <p>{{ $post->content }}</p>
        <a href="{{ url(&#39;posts/&#39; . $post->id) }}">more</a>
    </div>
@endforeach

show.blade.php

<h2>{{ $post->title }}</h2>
<p>{{ $post->content }}</p>

4. Routing

Finally, we need to create a route so that we can access our website in a browser. Add the following code to the routes/web.php file:

Route::get('/', 'PostController@index');
Route::get('/posts/{id}', 'PostController@show');

Now we can access the website in the browser. Enter the following command on the command line:

php artisan serve

Open the browser and visit http://localhost:8000 to see our new website.
