 | This template is used on approximately 100,000 pages. To avoid large-scale disruption and unnecessary server load, any changes to it should first be tested in the template's /sandbox or /testcases subpages, or in your own user subpage. The tested changes can then be added to this page in a single edit. Please consider discussing changes on the talk page before implementing them. |
 | This is a documentation subpage for Template:P2. It contains usage information, categories and other content that is not part of the original template page. |
The templates P1, P2 and P3 simply return the first, second and third unnamed input parameter respectively. For example:
{{P1|foo|bar|baz}}returns foo{{P2|foo|bar|baz}}returns bar{{P3|foo|bar|baz}}returns baz
These templates can be used inside other templates as an alternative to the {{#switch}} parser function, to switch between outputs based on whether the input is "1", "2" or "3":
{{P{{{1}}}|output if 1|output if 2|output if 3}}
Using {{#switch}}, this syntax is equivalent to
{{#switch:{{{1}}}|1=output if 1|2=output if 2|3=output if 3}}
except that the parser function strips whitespace between parameters whereas the templates don't.
