Hello,

I am trying to display some extra values in my theme file.

These are some images and text content which will be different for each survey.

eg. {{ aSurveyInfo.additional_params.image_1 }}

How do i pass these variable so i can access them in my theme file. As per above eg. how can i pass additional_params to theme file without editing core file code

I am using LimeSurvey Version 3.17.17

You can access ExpressionScript (ExpressionManager) variables inside TWIG templates via processString.
E.g.

Even in old system i use {QCODE.NAOK} in template …

Then you can use {{ processString("{QCODE.NAOK}") }} in 3.X theme.
