How to Create and Use Traits in Laravel

Traits are a collection of reusable methods that are accessible in multiple classes. It shares code between classes that are not related by inheritance.

To access these methods in a class first need to define the trait using the use keyword and call the method using $this if it is not a static method otherwise use self::.

In this tutorial, I show how you can create and use Traits in the Controller in Laravel 9.

1. Creating Trait

Syntax –

<?php 
namespace App;

trait TraitName
{
    /**
    Methods
    **/

}

Create a new folder Traits in app/ to store all Traits.

Create Common.php file.
Set namespace to App\Traits.
I set the trait name to Common.
Created 2 methods –
- fun1() – Return string response.
- status() – Return Active or InActive text based on $status value.

Completed Code

<?php

namespace App\Traits;

trait Common {

   public function fun1(){

       return "Trait response";
   }

   public function status($status = 0){

       $statusText = "InActive";
       if($status == 1){
           $statusText = "Active";
       }

       return $statusText;
   }
}

2. Route

Open routes/web.php file.
Define 1 routes –
- / – Load index view.

Completed Code

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\PagesController;

Route::get('/', [PagesController::class, 'index'])->name('home');

3. Controller

Create PagesController Controller.

php artisan make:controller PagesController

Open app/Http/Controllers/PagesController.php file.
Import Common Trait – use App\Traits\Common;
To use it inside the class use the use keyword – use Common;.
Create a method –
- index() – Calling trait function using $this –

$this->fun1(); 
$this->status(1);

and assign to the $data Array. Load index view and pass $data Array.

Completed Code

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Traits\Common; // Trait

class PagesController extends Controller
{
    use Common; // Trait

    public function index(){
        $data['value1'] = $this->fun1(); // Call trait method
        $data['value2'] = $this->status(1); // Call trait method

        return view('index',$data);
    }

}

4. View

Create index.blade.php file in resources/views/ folder.

Display $value1 and $value2 data.

Completed Code

<!DOCTYPE html>
<html>
<head>
   <meta charset="utf-8">
   <meta name="viewport" content="width=device-width, initial-scale=1">
   <title>How to create and use Traits in Laravel</title>

</head>
<body>
   {{ $value1 }} <br>
   {{ $value2 }} 

</body>
</html>

Use Traits to perform any reusable operation across multiple classes like – file upload, calculations, database manipulation, etc.

You can import more than one trait in your controller and use it.
