 | This template is used on many pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage. Consider discussing changes on the talk page before implementing them. |
The templates P1 and P2 simply return the first respectively second unnamed input parameter respectively. For example:
{{P1|foo|bar|baz}}returns foo{{P2|foo|bar|baz}}returns bar
These templates can be used inside other templates as an alternative to the Template:Pf parser function, to switch between outputs based on whether the input is "1" or "2":
{{P{{{1}}}|output if 1|output if 2}}
Using {{#switch}}, this syntax is equivalent to
{{Template:Hashswitch:{{{1}}}|1=output if 1|2=output if 2}}
except that the parser function strips whitespace between parameters whereas the templates don't.
