You should really sort out your theme. There shouldn't be a need for {% include ... %} tags. Symfony Twig already is bad as is, and shouldn't have controller logic in it.

[punitkumar]

A Theme author must be aware and avoid using {% include ... %} tags. in Opencart context.

While I fully agree with @mhcwebdesign , may I ask why includes should be avoided? OpenCart is since the beginning full of repetitions (not only at the theme, also with language variables which leads to a lot of useless MB in the package which could be avoided), so why should a theme not use include to load a piece of theme which is used in several places?

[mhcwebdesign]

Template repetitions are usually a sign of a poor overall design, and should be resolved by creating a separate controller and template.

Quite a lot of Symfony Twig's functions and tags should be removed and become part of the controller or model logic. A template engine should be limited to template rendering, initiated by the controller with a given set of variables.

Symfony Twig uses a horrible syntax, as is, copied from Django and Python, it has no clear LALR syntax design.
