ထာမ်ပလိက်:7
Unexpected use of template {{7}} - see Template:7 for details.
Template documentationTemplates {{1}}, {{2}}, {{3}}, etc. warn readers/editors that a typo exists in the page they are reading/editing. If {{7}} is called, you probably meant the parameter 7 (as {{{7}}} with triple braces), but in fact only double braces were used, invoking {{7}}. 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 {{7}}}, as invoking Template:7 +"}" rather than parameter 7. This can be an insidious problem, especially when the transclusion of Template:7 is hidden, so that the effect is invisible to the person editing a page. For that reason, Template:7 now issues a warning to the user.
With that warning, the prior invisible access to Template:7 can now be understood to be a formerly unseen problem coded within a page.
- Note: this will also pick up several variations such as {{7|}} for {{{7|}}} and {{{7}}.
Periodically, people check what-links-here to see if anyone has accidentally invoked Template:7.
