Laravel 8: Create a Custom Helper Function

In this article, I will give you an example of the “Custom helper function in laravel“, So you can easily apply it with your laravel 5, laravel 6, laravel 7, and laravel 8 application.

What we will cover:

1. Register Helper in composer.json
2. Get data in controller using helper
3. Get data in Blade File using helper.

we call all the category table data in the controller and blade file using a custom helper.

Create a folder and a file :

In this step, you need to create app/Helpers/helpers.php in your laravel project and put the following code in that file:

 "autoload": {
         "files": [
            "app/Helper/Helpers.php"
        ],

        "psr-4": {
            "App\\": "app/"
        },
        "classmap": [
            "database/seeds",
            "database/factories"
        ]
    },

Regenerate the list of all classes in the app, Hit this command in the terminal.

composer dump-autoload

Now we create a function in Helper\Helpers.php file to get the category data from the database using Category Model.

app\Helper\Helpers.php

 <?php
  namespace App\Helper;
  use App\Model\Category;

  class Helpers
  {
    #Get Category Data From Category Model
    static function get_catdata()
    {
        $catdata = Category::get();
        return $catdata;
    }
  }

  ?>

Now, we can call our function anywhere in the view and controller like this:

Get data in blade file using helper :

<table class="table">
            @php
            $catData = \App\Helper\Helpers::get_catdata()
            @endphp
            <thead>
               <tr>
                  <th>S.no</th>
                  <th>Category Name</th>
               </tr>
            </thead>
            <tbody>
               @foreach($catData as $key => $data)
               <tr>
                  <td>{{ $key+1 }}</td>
                  <td>{{ $data->name }}</td>
               </tr>
            </tbody>
            @endforeach
         </table>

Output :

Get data in controller using helper :

<?php

  namespace App\Http\Controllers;

  use Illuminate\Http\Request;
  use App\Helper\Helpers;

  class TestController extends Controller
  {

   public function categoryList()
   {

    $data = Helpers::get_catdata();
    dd($data);
   }
 }
