W3TPL/tag/let

About

• Action: Assigns a value to a variable.
• Options:
  • echo: replace the tag with the resulting value
  • index= treats name as an array, and specifies the element to use
  • name= name of variable to set
  • null: set the variable to NULL
  • oparse: parse the output (only has an effect if "echo" is present)
  • self: takes starting value from same variable, to allow unary operations

Currently unsupported:

• • load (should probably be "fetch"): retrieve starting value from the current page's properties
  • save (should probably be "store"): store the result in the properties for the current page
