How to Store Array in Database in Laravel

Published on Aug 14, 2022

Hello Artisans, today I'll show you how to store array in your database column. Sometimes we may need to store array of data or json data in our column. But mysql doesn't support array to be stored. And today's tutorial I want to show you how do to that in a easier and in a Artisan way. So, no more talk let's see how we can easily store such data in our database column.

Note: Tested on Laravel 9.19.

Create Model, Migration and Controller

For creating a model, migration and controller we just need to fire the below command in our terminal

php artisan make:model Article -mcr

and it'll create a model called Article.php, ArticleController.php and article_migrations. We'll work later with these files.

Setup Migration

Now we'll setup our migration file that we created on step1, here we'll create the table schema for our articles table. Let's see the below code snippet.

database/migrations/2022_08_14_151755_create_articles_table.php
<?php

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

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

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

Setup Model

Now we'll setup our model file that we created on step1, here we'll add our table columns into fillable property and also cast the details column as array, so that we can store arrays of data in our database. Let's see the below code snippet.

app/Models/Article.php
<?php

namespace App\Models;

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

class Article extends Model
{
    use HasFactory;

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

    protected $casts = ['details' => 'array'];
}

Setup Controller

Now we'll setup our controller that we created on step1, here we'll give the input as array and it'll store on detail's column. And also if we want to retrieve these column, it'll print the result in array. Let's see the below code snippet

app/Http/Controllers/ArticleController.php
<?php

namespace App\Http\Controllers;

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

class ArticleController extends Controller
{
    public function create(Request $request)
    {
        $data = [
            'title' => 'Article',
            'details' => [
                'category_1' => 'Laravel',
                'category_2' => 'VueJs',
                'category_3' => 'Mysql',
            ]
        ];

        $article = Article::create($data);

        dd($article->details);
    }
}

Create Route

Let's put the below route in web.php

routes/web.php
Route::resource('store-array',\App\Http\Controllers\ArticleController::class)->only('create');

Output

And finally we're ready with our setup. It's time to check our output. Now go to http://127.0.0.1:8000/store-array/create, If everything goes well (hope so) you can find a below output on.
