Use Revolution’s Lexicons.
In your chunk:
[[%lexicon_entry_key? &topic=`topicName` &namespace=`namespaceName`]]
So, say you put all your langauge files in the ’mysite’ Namespace (Namespaces can be used to group lexicon entries and topics), and had a Topic called ’sports’. You can create as many Topics as you like. Say you want to grab the Lexicon Entry with the key ’welcome_message’ from the Topic ’sports’.
You’d then put this in your chunk:
[[%welcome_message? &topic=`sports` &namespace=`mysite`]]
This would then render the translation (depending on what language you’ve initialized that Context in) for the Lexicon Entry ’welcome_message’. It would also load the ’sports’ Topic and ’mysite’ Namespace. You only need to load the Topic/Namespace once on a page.
MODx recommends you prefix your Lexicon Entries with some prefix to distinguish them from other Components Lexicon Entries. But you can do it however you want.
