{{if either (|a) (|b) (|first result) (|second result)}}
This helper template is designed to be used in other templates. It can help editors create template code that is more self documenting. A major advantage of using this template over using the construct {{#if:{{{1|}}}{{{2|}}} |…}}
is that if the first parameter is not empty then the second parameter is not evaluated.
The "or" in the "a or b" above is inclusive: if both a and b are true, the template will return the first result.
This template can also be used to replace the construct {{#if:a |true |{{#if:b |true |false}}}}
(i.e. "if a, then true; else if b, then true; else false").
Code | Result |
---|---|
{{if either |a |b |true |false}} | true |
{{if either |a | |true |false}} | true |
{{if either | |b |true |false}} | true |
{{if either | | |true |false}} | false |
