Template: if -- performs if-then-else


  • 1 -- the condition to test (defined or undefined parameter, etc.)
  • then -- what to do if condition is true
  • else -- what to do if condition is false


Note that you can skip then or else if you do not want to include it. Examples:
{{if|{{{username|}}}|then=Name is {{{username}}}|else=Who is this?}}
{{if|{{{username|}}}|else=Who is this?}}
