Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

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

Create Table Migration

We will create a migration file for items table. Open project into terminal and run this command.

$ php artisan make:migration create_items_table

It will create a migration file 2023_09_07_110040_create_items_table.php inside /database/migrations folder.

Open migration file and write this code into it.

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     */
    public function up(): void
    {
        Schema::create('items', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->json('data')->nullable();
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     */
    public function down(): void
    {
        Schema::dropIfExists('items');
    }
};

Run Migration

Next,

To migrate migration so that we create the schema of items table inside database.

$ php artisan migrate

It will create items table.

Setup Model

Open project terminal and run this artisan command to create model.

$ php artisan make:model Item

It will create a file Item.php inside /app/Models folder.

Open Item.php and write this code into it.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Casts\Attribute;

class Item extends Model
{
    use HasFactory;

    protected $fillable = [
        'title', 'data'
    ];

    /**
     * @return \Illuminate\Database\Eloquent\Casts\Attribute
     */
    protected function data(): Attribute
    {
        return Attribute::make(
            get: fn ($value) => json_decode($value, true),
            set: fn ($value) => json_encode($value),
        );
    }
}

Concept

Here, this is the concept of laravel model known as get and set method blocks. While processing data input these methods will be used.

get: fn ($value) will be used when we fetch data from database table. Automatically it will process the incoming data from db.

set: fn ($value) will be used when we save data into database.

protected function data(): Attribute
{
    return Attribute::make(
        get: fn ($value) => json_decode($value, true),
        set: fn ($value) => json_encode($value),
    );
}

Here, before data save -> json_encode() will be used. And when data get from database json_decode() will be used.

Next,

Create Controller

Back to project terminal and run this command,

$ php artisan make:controller ItemController

It will create ItemController.php file inside /app/Http/Controllers folder.

Open controller file and write this code into it.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Item;

class ItemController extends Controller
{
    public function index()
    {
        $input = [
            'title' => 'Sample Title',
            'data' => [
                '1' => 'First',
                '2' => 'Second',
                '3' => 'Third'
            ]
        ];

        $item = Item::create($input);

        dd($item->data);
    }
}

You can see, we are creating an item with title (a string value) and data (an array of values).

Add Route

Open web.php file from /routes folder. Add this route into it.

//...
use App\Http\Controllers\ItemController;

Route::get('item', [ItemController::class, 'index']);

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/item

Once you hit this URL, your data will be saved into database into encoded format and also will get outputted in decoded format.
