Forum:The "if" command

The #if: command. Is there anywhere I can find out how to use this? But if there isn't, I'll keep it short: So, I have a Talk template at a wiki, it involves me to type " ". I want to use the #if: command to add something else. So when I type " ", it will choose another template with the extra . So if I were to call the first template " " and the second "  " what would the code be (if it is possible) to choose the template based on if there's three "|"s --I Lion Heart I 19:16, 30 September 2008 (UTC)


 * See c:help:Help:Parser_functions and Forum:Template or Parser Function Expansion Problem.


 * Your third parameter will require at least one character (computing), and it probably needs to be a non-whitespace (computer science) character (i.e., not a spacebar or Enter character).


 * Place that anywhere (multiple places if necessary) in your code. If the third parameter was not passed, an empty value is used in its place. --Jesdisciple (talk) 20:30, 30 September 2008 (UTC)
