QR codes are sometimes needed for product identity, inventory and others. Then how do you generate a QRcode? It's easy, we can use Simple QRcode to create QRcode in the laravel framework.

In this article, we will both learn how to create or generate a QRcode so that when the code we can be directed to an SMS, email, website or just to find out what data is behind the QR code.

In this experiment we will start everything from scratch, which is preceded by creating a new laravel project. Following are the steps:

* Create a laravel project by going to the directory where you want to create the laravel project. Just like the instructions from laravel, we can create a new project with the command like below.

```
composer create-project --prefer-dist laravel/laravel qrcode
```

* If the laravel project has been successfully created, then enter the project directory and run the command from Simple QRcode as below.

```
composer require simplesoftwareio/simple-qrcode "~4"
```

* Create a new controller file with the command below.
```
php artisan make:controller DataController
```

* Then create a model as well as a migrate file to create a data container table that will be generated into a QRcode. The command to make the model / migrate can be seen as below.
```
php artisan make:model Data -m
```

* Open the Data Migrate file in the database> migrations folder and edit it so that it looks like below.
```php
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateDataTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('data', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('email');
            $table->bigInteger('phone');
            $table->timestamps();
        });
    }
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('data');
    }
}
```
* Create a new database in phpmyadmin, adminer, laragon or others.

* Match DB_DATABASE in the .env file with the name of the newly created database.

* When the new database has been created, return to the terminal and run the command **php** **artisan** **migrate**.

* Open the DataController file that was created in step 3, then edit the code as shown below.
```php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use SimpleSoftwareIO\QrCode\Facades\QrCode;
use App\Models\Data;
class GenerateController extends Controller
{
    public function index(){
        $data = Data::all();
        return view ('welcome', ['data' => $data]);
    }
    public function store(Request $request){
        $data = new Data;
        $data->name = $request->name;
        $data->email = $request->email;
        $data->phone = $request->phone;
        $data->save();
        return back();
    }
    public function generate ($id)
    {
        $data = Data::findOrFail($id);
        $qrcode = QrCode::size(400)->generate($data->name);
        return view('qrcode',compact('qrcode'));
    }
}
```
NB:

> Function index berfungsi untuk menampilkan data-data dari database (table data).

> Function store berfungsi untuk menambahkan data baru ke dalam table data (model Data).

> Function generate berfungsi untuk membuat QRcode dari data yang ingin di generate menjadi QR code (nama, email atau phone number).

* Buka file web.php yang ada di folder routes, kemudian edit menjadi seperti di bawah ini.
```php
<?php
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\DataController;
/*
|--------------------------------------------------------------------------
| 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('/', [DataController::class, 'index']);
Route::post('/', [DataController::class, 'store'])->name('store');
Route::get('qrcode/{id}', [DataController::class, 'generate'])->name('generate');
```
* Open the welcome.blade.php file in the views folder, then edit it as shown below.
```php

Okay, now we try to run the program by running the server (php artisan serve). Open url 127.0.0.1:8000 or qrcode.test.
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/x0um42kytjdsk3rnesf8.png)

The front page display or from the welcome.blade.php file will be like the picture above, then we try to input data on 3 existing forms, namely name, email, phone number and then click create to add the data.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/hm979u5ij1rmihl1w74q.png)

To see the QR code from some existing data, press the Generate button. Then it will display a QR code from the data as can be seen in the image above.

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/fq54p0w7ikf59b9m59a5.jpg)

If we try to scan using a cellphone scanner or something else, when the scanner captures the QR code, we will be directed to a page that looks like the image above.

From here, we have succeeded in creating a QR code in laravel which when we scan it will display the name data. Then how do we make it when we scan, we are redirected to an email? read more at [Codelapan.com](https://codelapan.com/post/generate-qr-code-dengan-simple-qrcode-di-laravel);
