Mastering Long Text Translation in Symfony5: A Comprehensive Guide

If you're diving into the world of Symfony5 and its symfony/translation package, you might encounter a common challenge: translating long blocks of text that include HTML markup. This task becomes even more complex when you’re working with multiple languages, such as English (EN) and Polish (PL). In this guide, we will address this issue and provide a structured solution to help you translate lengthy content effectively without sacrificing readability or maintainability.

The Problem: Long Text Translation with HTML Markups

When translating long texts in a twig template, developers often find themselves struggling to manage multiple languages while maintaining proper formatting and markup.

Example Scenario

Imagine you have the following content that you want to translate:

You may have successfully used the translatable block for shorter, simpler strings using the {% trans %} tags:

However, moving to longer phrases combined with HTML marks can create a mess quickly, making your template difficult to read and maintain.

The Solution: Use Translation Keys Instead of Inline Translation Tags

The best practice for handling long text translations while keeping your code organized is to use translation keys. This method not only provides clarity but also improves the overall structure of your template.

Step-by-Step Breakdown

Define Translation Keys: Create meaningful keys for each block of text in your translation file. Here’s an example for the messages.en.yaml file:

Benefits of Using Translation Keys

Improved Readability: Your twig templates remain clean and easy to read.

Ease of Maintenance: Updating translations doesn’t involve sifting through HTML tags.

Flexible Layout for Copywriters and Translators: While there’s a slight drawback regarding layout changes, this method provides a clear framework for text and content adjustments.

Conclusion

Using translation keys to manage long text translations with HTML markups in Symfony5 significantly simplifies the process. By following the steps above, you can ensure your code is not only functional but also maintainable. This approach enhances collaboration between developers and translators, allowing for clearer communication and improved workflow.

With the right techniques, tackling complex translation requirements becomes not just feasible, but also enjoyable. Happy coding!
