In this tute, we will discuss laravel store json in database. This article goes in detailed on laravel store json in database. I’m going to show you about laravel save json in database. I explained simply step by step laravel save json in db.

You can use this example with laravel 6, laravel 7, laravel 8, laravel 9, laravel 10 and laravel 11 version.

Sometimes, if we have large data or unfixed columns then we can not create too many fields in a database table with the nullable field. so we have to use JSON data type to store values, that way we can store large data or unstructured data. if you want to store a JSON array in a database in laravel then I will give you a simple example of how to store a JSON array store and access it from the database in laravel.

In this example, first, we will create migration with a JSON column. Then we will create a model with a getter and setter. when you create records then you can pass them as an array and when you get records then you will find an array. so let's see a simple example and learn it.

Step 1: Install Laravel

This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Create Migration

Here, we need create database migration for "items" table with title and data(JSON Column) columns and also we will create model for items table.

php artisan make:migration create_items_table

database/migrations/2022_07_11_141714_create_items_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('items', function (Blueprint $table) {
            $table->id();
            $table->string('title');
            $table->json('data')->nullable();
            $table->timestamps();
        });
    }
  
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('items');
    }
};

Then run migration command to create items table.

php artisan migrate

Step 3: Create Model

In this step, we will create Item.php model with getter setter. let's create model and update following code:

php artisan make:model Item

App/Models/Item.php

<?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;
  
    /**
     * Write code on Method
     *
     * @return response()
     */
    protected $fillable = [
        'title', 'data' 
    ]; 
  
    /**
     * Get the user's first name.
     *
     * @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),
        );
    } 
}

Step 4: Create Route

In third step, we will create one route for testing. so create one route here.

routes/web.php

<?php
 
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\ItemController;
   
/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/
     
Route::get('item', [ItemController::class, 'index']);

Step 5: Create Controller

In this step, we will create ItemController file and write index() method to create item records with array and access as array.

app/Http/Controllers/ItemController.php

<?php
  
namespace App\Http\Controllers;
  
use Illuminate\Http\Request;
use App\Models\Item;
  
class ItemController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $input = [
            'title' => 'Demo Title',
            'data' => [
                '1' => 'One',
                '2' => 'Two',
                '3' => 'Three'
            ]
        ];
  
        $item = Item::create($input);
  
        dd($item->data);
  
    }
}

Run Laravel App:

All the required steps have been done, now you have to type the given below command and hit enter to run the Laravel app:

php artisan serve

Now, Go to your web browser, type the given URL and view the app output:

http://localhost:8000/item

You can see database output and print variable output:

Database Output:

Output:

array:3 [
  1 => "One"
  2 => "Two"
  3 => "Three"
]

I hope it can help you...
