Get Google Translate API Key
Sign up at Google Cloud Console
Enable the Google Cloud Translation API
Get an API key from Credentials โ API Key
<?php ?>Create a Translation Helper in CodeIgniter 4
Create a helper file:
๐ app/Helpers/translation_helper.php
function translate($text, $targetLang = 'en')
{
$apiKey = 'YOUR_GOOGLE_TRANSLATE_API_KEY';
$url = "https://translation.googleapis.com/language/translate/v2?key={$apiKey}&q=" . urlencode($text) . "&target={$targetLang}";
$response = file_get_contents($url);
$json = json_decode($response, true);
return $json['data']['translations'][0]['translatedText'] ?? $text;
}Autoload the Helper
In app/Config/Autoload.php, add 'translation' to helpers:
public $helpers = ['url', 'form', 'translation'];Modify Your Controller to Use Auto-Translation
๐ app/Controllers/MockTestController.php
namespace App\Controllers;
use App\Models\MockTestModel;
use CodeIgniter\Controller;
class MockTestController extends Controller
{
public function show($id)
{
$model = new MockTestModel();
$mockTest = $model->find($id);
$lang = session()->get('lang') ?? 'hi'; // Default language is Hindi
$data['title'] = ($lang === 'hi') ? $mockTest->title : translate($mockTest->title, $lang);
$data['description'] = ($lang === 'hi') ? $mockTest->description : translate($mockTest->description, $lang);
return view('mock_test_view', $data);
}
public function switchLanguage($lang)
{
session()->set('lang', $lang);
return redirect()->back();
}
}Modify View to Display Translated Content
๐ app/Views/mock_test_view.php
<h1><?= esc($title); ?></h1>
<p><?= esc($description); ?></p>
<!-- Language Switch Links -->
<a href="<?= site_url('switch-language/en'); ?>">English</a> |
<a href="<?= site_url('switch-language/hi'); ?>">เคนเคฟเคจเฅเคฆเฅ</a>Define Routes
๐ app/Config/Routes.php
$routes->get('switch-language/(:segment)', 'MockTestController::switchLanguage/$1');Final Output
Now when you click "English", it will:
1๏ธโฃ Store 'en' in the session
2๏ธโฃ Automatically translate all content using Google Translate API
3๏ธโฃ Show the translated content without modifying your database
Advantages of This Approach

Works for all dynamic content: blogs, mock tests, current affairs, etc.
โ
Supports multiple languages
โ
Easy to implement, no database changes
