 | This is a documentation subpage for Template:Getalias2. It contains usage information, categories and other content that is not part of the original template page. |
This is a more general version of {{Getalias}}, which can extract any parameter value from a country data template instead of just parameters named "... alias" or "... alias-...".
Examples
{{getalias2|Mir|flag alias}}MirFlag.png(the value of|flag alias=in {{Country data Mir}}){{getalias2|Georgia (U.S. state)|shortname alias}}Template:Country data Georgia (U.S. state)(the value of|shortname alias=in {{Country data Georgia (U.S. state)}}){{getalias2|Nepal|border}}Template:Country data Nepal(nothing, since|border=is set to nothing in {{Country data Nepal}}){{getalias2|Lusitania|border}}{{{border}}}(no|border=parameter is defined in {{Country data Lusitania}}){{getalias2|Nepal|size}}Template:Country data Nepal(in {{Country data Nepal}}, the{{{size}}}parameter is passed through with fallback value 23x20px){{getalias2|Lusitania|size}}(in {{Country data Lusitania}}, the{{{size}}}parameter is passed through with empty fallback value)
Usage with variant
The |variant= parameter can be used to extract a variant parameter value, and returns the main parameter value if the variant parameter is undefined:
{{getalias2|Columbia|flag alias|variant=firstempire}}Columbia Flag.GIF(the value of|flag alias-first empire=){{getalias2|Columbia|flag alias|variant=foo}}NewColumbiaFlag.png(non-existent variant; returns the value of|flag alias=as fallback)
