Unexpected use of template {{13}} - see Template:13 for details.[1]
 | This is the template sandbox page for Template:13 (diff). |
Template documentationTemplates {{1}}, {{2}}, {{3}}, etc. warn readers/editors that a typo exists in the page they are reading/editing. If {{13}} is called, you probably meant the parameter 13 (as {{{13}}} with triple braces), but in fact only double braces were used, invoking {{13}}. In addition to a warning, it also adds pages to Category:Templates with incorrect parameter syntax. For more information on how template parameters work, see mw:Help:Templates#Parameters.
However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{13}}}, as invoking Template:13 +"}" rather than parameter 13. This can be an insidious problem, especially when the transclusion of Template:13 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:13 now issues a warning to the user.
With that warning, the prior invisible access to Template:13 can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{13|}} for {{{13|}}} and {{{13}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:13.
