Manual:WfMsgForContent

wfMsgForContent is used for retrieving messages in the content language, as opposed to the user language like  does. It should be used in places where the content does not change between users, such as the parsed result of wikipages (so in tag extension hooks and the like), or if the message is inserted directly in the database. In contrast, things like special pages change for each user, and should use.

Both this function, and wfMsg transform the message before returning it. This is like a step between full parsing and plain text. Certain things like are converted, but in general the text is not parsed into html.

Newer code is encouraged to use  instead of.
