How to Fix Localization Not Working in Laravel 8 with JSON Files

Localization is an essential feature for web applications, allowing them to serve users in their preferred languages. However, many developers encounter issues while implementing language features, particularly when working with Laravel 8 and JSON files for translations. If you're facing problems with localization in your Laravel application, you're not alone. This guide will guide you through the steps to effectively manage localization in Laravel 8 without running into common pitfalls.

The Problem

In a typical setup, developers use JSON files stored in the resource/lang/ directory. These files should be named according to the language shortcodes, such as en.json for English and ar.json for Arabic. However, while attempting to switch languages in their application, developers often find that the localization does not function as expected.

Example of Code Structure

In the HomeController, you might have logic to switch the language like this:

Additionally, developers sometimes try implementing middleware to handle the language switching more securely, but often, this strategy leads to unnecessary complications.

The Solution

One of the main issues with the original approach is the use of artisan commands every time the language is switched. This is unnecessary and can create performance issues for your application. Here's how to effectively manage localization in your Laravel 8 application without artisan calls.

Step 1: Store the Language in the Session

The first step to solving the localization problem is to store the user's selected language in the session. This allows the application to remember the user's language preference across requests.

Step 2: Update the Middleware

In your middleware, you need to check if a locale is set in the session. If it exists, set the application's locale based on this value.

Step 3: Consider Persistent Storage (Optional)

For a more robust solution, you might want to store the language preference directly in the user's table, especially if your application involves user accounts. This way, the language preference will persist across different devices and sessions.

Final Thoughts

When dealing with localization in Laravel 8, avoid unnecessary artisan calls when users switch languages. Instead, store the selected language in the session and manage the locale efficiently through middleware. By following these steps, you'll ensure that your Laravel application properly manages multiple languages with JSON file translations while providing a seamless experience for your users.

Conclusion

Implementing localization in Laravel can seem like a daunting task, but with the right approach, it can be straightforward. By leveraging sessions and middleware effectively, you can improve your application's language management without running into performance issues.
