W3TPL/tag/get

About

• Action: Tag is replaced by the value of a variable or expression.
• Options:
  • arg: get value from http request named name instead of using stored variable
    • Retrieves value from $wgRequest->getVal(name, default);
  • codes: process with ShowHTML() before output
  • default= default value to use if argument named arg is not set
    • This may eventually be used to fill in a value in other cases, but for now it doesn't.
  • index= offset into array named name
  • isolate: use extreme isolation to prevent parsing before output
  • lcase: convert to lowercase before output
  • len= maximum number of characters to include; truncate after nth character
  • name= name of variable to retrieve
  • raw: output should not be parsed (usage is restricted)
  • ucase: convert to uppercase before output
  • val= expression to use instead of variable name
