[edit] Addition of pp-template
{{editprotected}}
Based on User:Wknight94 protection, suggest adding {{pp-template}} to the top of the template page Tamr007 (talk) 10:09, 10 July 2008 (UTC)
[edit] Confused...
Could anyone explain me the usage of this template in the form of:
if condition then
statement1
else
statement2
I noticed that the documentation was somewhat unclear. Alexius08 is welcome to talk about his contributions. 14:13, 1 October 2008 (UTC)

- There are several parser functions for this, depending on the kind of condition, see mw:Help:Extension:ParserFunctions. This Template:If is a special version preserving newlines and spaces.--Patrick (talk) 11:39, 27 December 2011 (UTC)
[edit] If in multiple comparisons
Does anyone know how to use #if: when I want to check against multiple statements? Example:
- {{#if: {{{1}}} or {{{2}}}|do this if either condition is met|do that if condition is not met}}
Say i want to check e.g. whether 1 OR 2 is not an empty value in an infobox, how to accomplish that? The example i have does not work. There appaerently is a problem with multiple conditions? Or do i miss something? Regards, DTBone (talk) 18:18, 11 October 2008 (UTC)
- The parser function does not check params, you can use both together e.g {{#if:{{{a|}}}{{{b|}}}|...}} and if any of them have values it will be true, so e.g if a=a and b=b it would be "ab", thus returns true; there is no way to tell which param returns true though in the 1 function though, this should work for most of those cases though:
- {{#if:{{{a|}}}{{{b|}}}|{{{a|}}}{{{b|}}}}} - this will display both if true.
- {{#if:{{{a|{{{b|}}}}}}|{{{a|{{{b|}}}}}}}} - this will display a if true, but if a returns false it displays b (if true)
- {{#if:{{{a|}}}{{{b|}}}|{{{a|{{{b|}}}}}}}} - basically the same as above, just looks lamer.
- you can also nest a parser function in another:
- {{#if:{{{a|}}}|{{#if:{{{b|}}}|b=true|b=false}}|a=false}}
