Tài liệu bản mẫuUsage
Templates {{1}}, {{2}}, {{3}} etc warn readers/editors that a typo exists in the page they are reading/editing. If {{12}} is called, you probably meant the parameter 12 (as {{{12}}} with triple braces), but in fact only double braces were used, invoking {{12}}. In addition to a warning, it also adds pages to Category:Templates with incorrect parameter syntax.
However, the most problems have been caused by omitting the first brace "{" of a parameter and getting {{12}}}, as invoking Template:12 +"}" rather than parameter 12. This can be an insidious problem, especially when the transclusion of Template:12 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:12 now issues a warning to the user.
With that warning, the prior invisible access to Template:12 can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{12|}} for {{{12|}}} and {{{12}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:12.
