Calling variables, dynamically

Question

I've got a parent template which contains the following code:

{% include '_layout' with {'countryCode': 'au'} %}

I have a global set with the handle au_Variables, and within that a field with the handle vimeoVideoId_au

The problem I'm having is with trying to render the following global: {{ au_Variables.vimeoVideoId_au }} dynamically, using the countryCode.

I've tried

{% set videoId = countryCode~'_Variables.vimeoVideoId_'~countryCode %}

And then outputting {{ videoId }} but all I get is the string au_Variables.vimeoVideoId_au, not the rendered global.

Any ideas how to do this in Twig?

Not sure if you saw this, but you may also be able to use the Twig attribute function:

{{ attribute(array, item) }}

Pretty straightforward, here's the official docs page...

Thanks. it was the property being dynamic too which was causing me to have all sorts of issues. – Iain Urquhart Jul 03 '14 at 03:52
Noting here an application of this function because it was not 'straightforward' to me until I hit upon the solution by trial and error! In my case the variable is the Globals field handle, so I've ended up with {{ attribute(globalSetHandle, globalsFieldVariable') }}, which works a treat. – Jonathan Schofield Mar 20 '19 at 16:56

I've got a bit of a workaround, not sure if it's the best way to do it.

I restructured my fields, turns I don't need unique field names for the globals (still thinking in EE mode) so that took away half the problem.

I can access the global group dynamically, using _context

So after renaming my Video ID field, I can call the global set dynamically using:

{{ _context[countryCode~'_Variables'].vimeoId }}
