Hello :)
I don't know if someone has replied to you directly but this is what Tal
Expression Modifiers are for:
http://phptal.org/manual/en/split/custom-modifiers.html
Understanding and writing them can be a little tricky as the documentation is
not extensive but the key points to remember
As part of my integration into Zend Framework, I wrote a replacement translator
service for phptal. you basically just write a class that implements
PHPTAL_TranslationService and then when you create the phptal instance you call
its 'setTranslator' method and pass in an instance of your class.
