Working with localization and translations in Laravel is a common practice when building multilingual websites or applications. Laravel provides a simple and efficient way to manage translations and localize the content of your application.
To start working with localization and translations in Laravel, you first need to create language files in the resources/lang directory. Each language file should contain an array of key-value pairs, where the key is the original language text and the value is the translated text in the desired language.
Once you have created the language files, you can use the trans() helper function in your views to retrieve the translated text. The trans() function takes the key of the text to be translated as an argument and automatically fetches the corresponding translation from the appropriate language file.
You can also set the default language for your application in the config/app.php file by specifying the locale parameter. This allows your application to automatically switch to the correct language based on the user's preferences or the language selected by the user.
Overall, working with localization and translations in Laravel is a straightforward process that can greatly enhance the user experience of your application by making it accessible to users from different language backgrounds.
What is a translation key in Laravel?
In Laravel, a translation key is a string identifier that is used in language files to specify the translation for a particular piece of text. This key is then used in the application code to fetch the corresponding translation in the current language. By using translation keys, developers can easily manage and update translations without having to modify the application code.
How to generate language files from database in Laravel?
To generate language files from a database in Laravel, you can follow these steps:
- Create a new command by running the following command in your terminal:
1
|
php artisan make:command GenerateLanguageFiles
|
This will create a new command file in the app/Console/Commands
directory.
- Open the command file and update the signature and description properties to define the command name and description.
- Inside the handle method of the command file, write the logic to fetch data from the database and generate language files.
Here is an example of how you can generate language files from a database:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
use Illuminate\Console\Command; use Illuminate\Support\Facades\DB; class GenerateLanguageFiles extends Command { protected $signature = 'generate:language-files'; protected $description = 'Generate language files from database'; public function handle() { $translations = DB::table('translations')->get(); $output = []; foreach ($translations as $translation) { $output[$translation->key][$translation->locale] = $translation->value; } foreach ($output as $key => $values) { file_put_contents(resource_path("lang/{$key}.php"), '<?php return ' . var_export($values, true) . ';'); } $this->info('Language files generated successfully!'); } } |
- Register the newly created command in the app/Console/Kernel.php file by adding it to the $commands property:
1 2 3 |
protected $commands = [ Commands\GenerateLanguageFiles::class, ]; |
- Run the command in your terminal:
1
|
php artisan generate:language-files
|
This will fetch data from the translations
table in your database and generate language files in the resources/lang
directory based on the key-value pairs retrieved from the database.
Make sure to update the database table name and column names in the command file based on your actual database structure.
How to cache translations in Laravel?
In Laravel, you can cache translations using the php artisan config:cache
command. This command will cache all configuration files, including translations, to improve application performance.
However, if you want to specifically cache translations, you can use the php artisan translate:cache
command, which will generate a language file with all translations and cache it for faster retrieval.
You can also manually cache translations by using the Cache
facade in your application code. For example, you can store translations in the cache like this:
1 2 3 4 5 6 7 8 |
$translations = [ 'en' => [ 'hello' => 'Hello', 'goodbye' => 'Goodbye', ], ]; Cache::put('translations', $translations, 60); |
To retrieve cached translations, you can use the Cache
facade again:
1
|
$translations = Cache::get('translations');
|
By caching translations, you can reduce the number of database queries and improve the performance of your Laravel application.
