How to pass a custom function to a Laravel Blade template?

You don’t have to pass anything to blade. If you define your function, you can use it from blade.

1. Create a new app/helpers.php file.
2. Add your trim_characters function to it.
3. Add that file to your composer.json file.
4. Run composer dump-autoload.

Now just use the function directly in blade:

{{ trim_characters($string) }}
