How to use Laravel to develop an online review platform

Introduction:
With the rapid development of the Internet, users' demand for reviews and reviews is increasing day by day. Developing an online review platform can meet users' needs for evaluation and sharing of products, restaurants, attractions, etc. In this article, we will introduce how to use Laravel to develop a feature-rich online review platform.

1. Environment setup
First, we need to set up a development environment to run Laravel, including PHP, MySQL and Composer. You can learn how to build it through the official website or other tutorials.

2. Create a project
Open the terminal and use the following command to create a new Laravel project:

composer create-project --prefer-dist laravel/laravel online-review-platform

Next, enter the project directory:

cd online-review-platform

3. Create Database and data table
Create a new database in MySQL, and then configure the database connection information in the .env file in the project root directory.

Run the following command to create a data table migration file:

php artisan make:migration create_reviews_table --create=reviews

In the generated migration file, write the code that defines the data table structure. For example:

public function up()
{
    Schema::create('reviews', function (Blueprint $table) {
        $table->id();
        $table->text('content');
        $table->integer('rating');
        $table->timestamps();
    });
}

Run the data table migration command to create a data table:

php artisan migrate

4. Create model and controller
Run the following command to create a Review model and corresponding controller :

php artisan make:model Review -mc

In the generated model, define the mapping relationship with the data table:

use IlluminateDatabaseEloquentModel;

class Review extends Model
{
    protected $fillable = ['content', 'rating'];
}

5. Create routes and views
Open routes/web.php file, add the following code to define the relevant routes:

Route::get('/reviews', 'ReviewController@index');
Route::post('/reviews', 'ReviewController@store');

Open the generated controller file app/Http/Controllers/ReviewController.php, add the following code:

use AppReview;
use IlluminateHttpRequest;
use IlluminateSupportFacadesRedirect;

class ReviewController extends Controller
{
    public function index()
    {
        $reviews = Review::all();
        return view('reviews.index', compact('reviews'));
    }

    public function store(Request $request)
    {
        Review::create($request->all());
        return Redirect::back();
    }
}

Create a reviews subdirectory in the resources/views directory, and create a index.blade.php view file in this directory:

<h1>在线点评</h1>

<form action="/reviews" method="POST">
    @csrf
    <label for="content">评论内容</label>
    <textarea name="content"></textarea>

    <label for="rating">评分</label>
    <input type="number" name="rating" min="1" max="5">

    <button type="submit">提交</button>
</form>

<h2>所有评论：</h2>
@foreach ($reviews as $review)
    <div>
        <p>内容：{{ $review->content }}</p>
        <p>评分：{{ $review->rating }}</p>
    </div>
@endforeach

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

php artisan serve

Open the browser and visit http://localhost:8000/reviews, you can see The page of the online review platform. Fill in the review content and rating in the input box, click the submit button to add a review record, and display all reviews on the page.
