How to solve laravel language package not working

In Laravel development, language packs are a very useful feature that allows us to provide multi-language support for our applications. However, sometimes you'll run into a problem where your Laravel language pack doesn't work.

Specifically, this problem may manifest itself as your Laravel application not displaying the expected language, but instead displaying the default English text. This may be because your language pack is not loading correctly, or because your locale is configured incorrectly. Whatever the case may be, here are some possible solutions.

1. Check the language pack folder path

First, you should make sure that your language pack folder path is correct. In Laravel, the default language pack folder is located under resources/lang. You can store files in different languages ​​in different folders under this folder.

For example, you can store English files in the resources/lang/en folder and Chinese files in the resources/lang/zh-CN folder. . If your language pack is not loading correctly, then you need to check whether your language pack files are correctly placed in these folders.

2. Check the configuration file

Secondly, you should check the settings of the configuration file. In Laravel applications, the locale can be set through configuration files. By default, Laravel's locale can be set in the .env file. You can check if the correct locale variables are set in the .env file. The variable name of the locale variable is APP_LOCALE.

If your locale is set correctly, then you need to check the config/app.php file to make sure the locale option matches your expected locale.

3. Custom language pack loader

If neither of the above two methods can solve your problem, then you can consider customizing the language pack loader. By default, Laravel uses the Illuminate\Translation\TranslationServiceProvider service provider to load language packs. You can create a custom service provider and register the service provider through the $app->register() method.

You can override the boot() method in the custom service provider to complete the custom loading of the language pack. For example, you can add a path to a language pack's namespace using the addNamespace() method.

public function boot()
{
    $this->app->make('translator')->addNamespace('my-lang', realpath(__DIR__.'/../resources/lang'));

    $this->loadTranslationsFrom(realpath(__DIR__.'/../resources/lang'), 'my-lang');
}

4. Check the language pack file format

Finally, you need to check whether your language pack file conforms to Laravel's language pack file format. Laravel uses key => value key-value pairs to store language text, where key is the key of the language text and value is the value of the language text.

You need to make sure that your language pack file is returned as an array, as shown below:

return [
    'welcome' => '欢迎',
    'hello' => '你好'
];

Also, make sure that your language pack file is in the correct format and does not have any syntax errors. You can use Laravel's Artisan commands to check and fix syntax errors.

Conclusion

In Laravel development, language packs are a very useful feature that allow us to provide multi-language support for our applications. If you encounter a problem with language packs not working, you can diagnose and resolve it using the methods above. You can check the language pack folder path, configuration file settings, custom language pack loader, language pack file format, and other factors. Through these methods, you can better solve the problem of language pack not working and provide better multi-language support for your application.
