Creating Laravel Helpers

Although helpers are an important part of Laravel, the documentation doesn’t really touch on creating them. Fortunately, doing so it fairly easy.

Here I’m building a helper for formatting dates for the HTML5 datetime-local form input. First we define the helper function in app\Helpers.php:

<?php
use Carbon\Carbon;
if (!function_exists('format_date')) {
function format_date(string $date)
{
return Carbon::parse($date, config('app.timezone'))->format('Y-m-d\TH:i:s');
}
}

Then we create a service provider to load them:

<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
class HelperServiceProvider extends ServiceProvider
{
/**
* Bootstrap the application services.
*
* @return void
*/
public function boot()
{
//
}
/**
* Register the application services.
*
* @return void
*/
public function register()
{
//
require_once app_path() . '/Helpers.php';
}
}

Finally,we register the service provider in config/app.php:

'providers' => [
...
App\Providers\HelperServiceProvider::class,
],

Of course, once you have this all set up for one helper, it’s easy to add more because they can all go in app/Helpers.php.

Creating your own helpers is a good way of refactoring unwanted logic out of your Blade templates or controllers and making it more reusable and maintainable, particularly for things like formatting dates or strings.
