It looks like smarty modifiers are not yet implemented for AOS PDF Templates. I have tried to implement conditional smarty statement but it is not working.
Is this something to be available in the future releases?
I don’t see it in the new Roadmap…
I would work around this by looking for the code where the variables are being assigned and adding the logic there. This has the additional advantage of allowing the use of full PHP syntax and the Beans objects, instead of being limited to Smarty.
