Laravel default auth module translation

Question

I have generated the default Laravel auth module.

Everywhere in the blades of the module, I see Double Underscore __ function assuming that translation is almost there.

for example

<li>
  <a class="nav-link" href="{{ route('login') }}">
    {{ __('Login') }}
  </a>
</li>

My question: Where is the translation file? Where should I put it, if I create one?

I mean, if I go to the Laravel documentation site there are examples like this

echo __('messages.welcome');

with explanations

For example, let's retrieve the welcome translation string from the resources/lang/messages.php language file:

BUT in my example above there is no file name specified. It is only text:

__('Login')

Question is: What is used for the language file if no file specified? Is there any default? Where does it sit? Where was it set?

Answer 1

All the language translation files in Laravel should be stored in PROJECT_DIRECTORY/resources/lang. When you make an Auth with artisan, it automatically creates it. But if you can't find it, then create manually.

(1)

There's a way to using translation strings as keys by the docs. In this method you can create a JSON file in PROJECT_DIRECTORY/resources/lang with the name of your local, for example for Spanish name it es.json or German de.json, it depends on your local name.

Now create a JSON object and put the translations with the string name you used in your blade:

{
   "Login": "Welcome to Login Page!",
   "Logout": "You are logged out!",
}

Then use the PHP double underscores method to call your translations in blades:

{{ __('Login') }}

(2)

Create a file named auth.php in PROJECT_DIRECTORY/resources/lang directory. then put a simple php array like this on it:

<?php
  
  return [

    /*
      Translations go here...
    */

  ];`

Then add your translate strings to it:

  <?php
  
  return [

    'Login' => 'Welcome to Login Page!',
    'Logout' => 'You are logged out!',

  ];`

Now in the blade template simply do this:

<li>
  <a class="nav-link" href="{{ route('login') }}">
   {{ __('auth.Login') }}
  </a>
</li>

Answer 2

Laravel Docs Have an instruction about the json file. Yes it is not php, but json file. Example would be:

resources/lang/es.json

content

{
    "I love programming.": "Me encanta programar."
}

Usage

echo __('I love programming.');
