Hey there! If you're working with Laravel 12 and need reusable functions across your project, creating a custom helper function is the way to go. It saves time and keeps your code clean. In this guide, I'll show you how to set up a helper function in Laravel 12 step by step.

Steps to Create a Custom Helper Function in Laravel 12

 

Install laravel 12 using the following command.

laravel new example-app

 

In the app/Helpers/helpers.php create a new file.

if (!function_exists('greetUser')) {
    function greetUser($name)
    {
        return "Hello, " . ucfirst($name) . "!";
    }
}

 

Now, we need to tell Laravel to load our helpers.php file automatically. Open the composer.json file and find the autoload section. Add the helper file under the files array.

...
  
    "autoload": {
        "psr-4": {
            "App\\": "app/",
            "Database\\Factories\\": "database/factories/",
            "Database\\Seeders\\": "database/seeders/"
        },
        "files": [
            "app/Helpers/helpers.php"
        ]
    },
  
...

 

Run the following command to refresh Composer's autoload files:

composer dump-autoload

 

Now, you can use your helper function anywhere in your Laravel app, like controllers, views, or even routes.

$name = "john";
echo greetUser($name); // Output: Hello, John!

Using Helpers in Blade Templates

You can also use this function inside a Blade file like this:

<p>{{ greetUser('jane') }}</p>
