TPL → TWIG migration FAQ

Why migrate from TPL to TWIG "TPL to TWIG Code Converter" ?

The TPL engine is locked to OpenCart 2.x and is no longer maintained. TWIG is the standard for OpenCart 3.x and later: safer, faster, with template inheritance, macros and filters.

Is the generated TWIG compatible with OpenCart 3.x?

Yes. The converter produces output that is fully compatible with the default OpenCart 3.x template engine — variables, conditions, loops, filters, and include statements.

How are complex PHP expressions handled?

Simple echo, if and foreach are converted automatically. Complex constructs (foreach with keys, switch, ternaries) need to be ported manually — the converter will mark them with comments.

Are comments and formatting preserved?

HTML markup, indentation and line breaks are kept. PHP comments are converted into TWIG comments {# #}, HTML comments stay untouched.

How to verify the result before going live?

Paste the generated TWIG into a test .twig file of your theme and inspect the page rendering. The reverse converter is also available so you can cross-check both versions.

Can I convert an entire theme at once?

The web interface processes one template at a time. For bulk migration we recommend the convertTplToTwig.php script — it lives in the project root and accepts a folder of .tpl files.

Is the source code safe during conversion?

Yes. The converter runs locally in your browser, the source code is never sent anywhere. The server-side script also makes no external requests.

What if TWIG throws a parse error?

Check the syntax of the original TPL — unclosed quotes, broken tags. If the error persists, send a sample through the feedback form and we will add support for your case.

Why do you need a TPL to TWIG converter?

The free TPL to TWIG converter from DEV-OPENCART.COM allows you to quickly convert OpenCart templates from the legacy TPL format to the modern Twig syntax.

This tool will be useful for developers updating OpenCart online stores, modernizing old modules, or adapting their own solutions to new versions of the system.

DEV-OPENCART.COM offers dozens of OpenCart modules, so we understand the complexities that arise when migrating between different platform versions. The TPL to TWIG converter was created to simplify template migration and reduce manual work when updating projects.

Starting with OpenCart 3.x, Twig has been used as the templating engine , replacing classic TPL templates. Therefore, when migrating modules, templates, or themes to modern versions of OpenCart, developers often need to convert existing TPL code to Twig format.

Manually translating templates can be time-consuming, especially if the project contains a large number of files and custom modifications. The converter automatically handles popular TPL constructs and helps you build a foundation for further work with Twig templates in OpenCart.
