Laravel Multi Language Translation using lang() Tutorial
In this post we will show you Laravel Multi Language Translation using lang(), hear for Laravel Multi Language Translation using lang() we will give you demo and example for implement.
We almost project require to add multi-language support like we can change the language in our blog or website on the front end. Laravel also provide localization helper like lang(), trans() etc for multiple language support. So if you require basic translation like label changes and title etc then you should have to use laravel default localization. Laravel also provide to manage with json. you can easily change language using language code.
So, in this post, we would like to show you how we can manage in back-end side in laravel 5.6 and how you can use it. we will create languages table with name and language code. then we will create default en.json file on lang folder. as we know english is default language. we will create one page on back-end side and that will manage all languages key and value of json file. it is a amazing, you can see on demo and also you can download code of this post.
After complete all the steps, you will get layout like as bellow example, so let’s see that too.
Preview:
Step 1: Create languages table
In first step, we are going to create multi language translation. so we have to create migration for “languages” table using Laravel 5.6 php artisan command, so first fire bellow command:
php artisan make:migration php artisan make:migration <b>create_languages_table</b>
After this command you will find one file in following path “database/migrations” and you have to put bellow code in your migration file for create tags table.
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreateLanguagesTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('languages', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('code');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('languages');
}
}
now you can run migration by following command:
php artisan serve
Step 2: Create Seeder for Language
So, in the second step, we need to add seeder for language table, so we will create three language by default. so let’s create seeder by bellow command:
php artisan make:seeder CreateLanguages
database/seeds/CreateLanguages.php
<?php
use Illuminate\Database\Seeder;
class CreateLanguages extends Seeder
{
/**
* Run the database seeds.
*
* @return void
*/
public function run()
{
\DB::table('languages')->insert(['name' => 'English', 'code' => 'en']);
\DB::table('languages')->insert(['name' => 'Italy', 'code' => 'it']);
\DB::table('languages')->insert(['name' => 'Franch', 'code' => 'fr']);
}
}
Now you can run seeder by following command:
php artisan db:seed --class=CreateLanguages
Step 3: Add Route
In this is step we need to add routes for language translation. so open your “routes/web.php” file and add following route.
routes/web.php
Route::get('languages', 'LanguageTranslationController@index')->name('languages');
Route::post('translations/create', 'LanguageTranslationController@store')->name('translations.create');
Route::post('translations/updateKey', 'LanguageTranslationController@transUpdateKey')->name('translation.update.json.key');
Route::post('translations/update', 'LanguageTranslationController@transUpdate')->name('translation.update.json');
Route::delete('translations/destroy/{key}', 'LanguageTranslationController@destroy')->name('translations.destroy');
Route::get('check-translation', function(){
\App::setLocale('fr');
dd(__('website'));
});
Step 4: Create LanguageTranslationController Controller
Here, in this step we need to create new controller for create language translation. so create “LanguageTranslationController” controller and put bellow code:
app/Http/Controllers/LanguageTranslationController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use DB;
use File;
class LanguageTranslationController extends Controller
{
/**
* Remove the specified resource from storage.
* @return Response
*/
public function index()
{
$languages = DB::table('languages')->get();
$columns = [];
$columnsCount = $languages->count();
if($languages->count() > 0){
foreach ($languages as $key => $language){
if ($key == 0) {
$columns[$key] = $this->openJSONFile($language->code);
}
$columns[++$key] = ['data'=>$this->openJSONFile($language->code), 'lang'=>$language->code];
}
}
return view('languages', compact('languages','columns','columnsCount'));
}
/**
* Remove the specified resource from storage.
* @return Response
*/
public function store(Request $request)
{
$request->validate([
'key' => 'required',
'value' => 'required',
]);
$data = $this->openJSONFile('en');
$data[$request->key] = $request->value;
$this->saveJSONFile('en', $data);
return redirect()->route('languages');
}
/**
* Remove the specified resource from storage.
* @return Response
*/
public function destroy($key)
{
$languages = DB::table('languages')->get();
if($languages->count() > 0){
foreach ($languages as $language){
$data = $this->openJSONFile($language->code);
unset($data[$key]);
$this->saveJSONFile($language->code, $data);
}
}
return response()->json(['success' => $key]);
}
/**
* Open Translation File
* @return Response
*/
private function openJSONFile($code){
$jsonString = [];
if(File::exists(base_path('resources/lang/'.$code.'.json'))){
$jsonString = file_get_contents(base_path('resources/lang/'.$code.'.json'));
$jsonString = json_decode($jsonString, true);
}
return $jsonString;
}
/**
* Save JSON File
* @return Response
*/
private function saveJSONFile($code, $data){
ksort($data);
$jsonData = json_encode($data, JSON_PRETTY_PRINT|JSON_UNESCAPED_UNICODE);
file_put_contents(base_path('resources/lang/'.$code.'.json'), stripslashes($jsonData));
}
/**
* Save JSON File
* @return Response
*/
public function transUpdate(Request $request){
$data = $this->openJSONFile($request->code);
$data[$request->pk] = $request->value;
$this->saveJSONFile($request->code, $data);
return response()->json(['success'=>'Done!']);
}
/**
* Remove the specified resource from storage.
* @return Response
*/
public function transUpdateKey(Request $request){
$languages = DB::table('languages')->get();
if($languages->count() > 0){
foreach ($languages as $language){
$data = $this->openJSONFile($language->code);
if (isset($data[$request->pk])){
$data[$request->value] = $data[$request->pk];
unset($data[$request->pk]);
$this->saveJSONFile($language->code, $data);
}
}
}
return response()->json(['success'=>'Done!']);
}
}
Step 5: Create Blade File
In the last step, we need to create languages.blade.php file for view. so create bellow file and put bellow code on it.
resources/views/languages.blade.php
