Template:Flag icon

File:Test Template Info-Icon - Version (2).svg Template documentationviewedithistorypurge

Template:Flag icon displays a flag of the named parameter in "icon" size, currently 23×15 pixels maximally (defined in Template:Flag icon/core), plus a one-pixel border. The image also has a clickable link to the associated article. For an unlinked flag icon, use Template:Flag decoration instead.

Please consider the Manual of Style section on flags before using this template.

Usage

{{Flag icon|name|variant=|size=|noredlink=}}

<syntaxhighlight lang="wikitext" inline style="display

none;" />|1=name: The first parameter is mandatory, and identifies the name of the country, region, city, etc. A full list of available values can be found in Category:Country data templates. For example, Template:Country data Peru is used when the name parameter is specified as Peru. Many flags are also available via shortened "aliases", such as standard three-letter country codes as specified by ISO 3166-1 alpha-3, IOC, or FIFA. The list of available "aliases" is found in Category:Country data redirects. Many of these country codes could be considered obscure, so it is recommended to use the full country name.

<syntaxhighlight lang="wikitext" inline style="display

none;" />|variant=: The second parameter is optional, and identifies a flag variant to be used instead of the standard flag. This is most often used for historical flags but can also be used to specify naval flags, sport-use flags, etc. The list of available flag variants for each country is documented on the specific page for the country data template. For example, Template:Country data Peru includes a description of each of the available flag variations for Peru. This parameter can be a named parameter (e.g.. "variant=1815"), or a positional parameter, always after the country name.

<syntaxhighlight lang="wikitext" inline style="display

none;" />|size=: This parameter is optional, and is used to specify the maximum width and/or height of the flag image. This parameter is specified using standard image syntax.

Implementation notes

This template uses the data templates listed under Category:Country data templates, which contain the data specifying what to display and the formatter Template:flag icon/core, which contains the logic of how to display the flag.

• {{flag icon|Peru}} → — uses Template:Country data Peru
• {{flag icon|PER}} → — uses Template:Country data PER, which is a redirect to Template:Country data Peru

Inside each country data template, this template uses the following parameters:

• flag alias — name of the image file to display
• flag alias-xxxx — name of the image file of flag variant xxxx
• alias — used to display the alt attribute of the image (defaults to "Flag of alias")

Tracking categories

• Category:Pages using flag icon template with unknown parameters (0)

Where {{flag icon|Foo}} is used, but the Template:Country data Foo does not exist, then a redlink is displayed, unless the <syntaxhighlight lang="wikitext" inline style="display: none;" />|noredlink=yes parameter has been set.

Where the redlink is displayed, the page is added to a tracking category:

• Category:Flag icons missing country data templates (population: 21)

Related templates

• Template:Flag is used to display a wikilinked name next to the flag. The displayed name will be the same as the parameter used with the template, but the link target will be the main article for the country (in these examples, Peru).
  • {{flag|Peru}} → Peru
  • {{flag|PER}} → PER
• Template:Flag country is also used to display a wikilinked name next to the flag. The displayed name will always be the same, regardless of whether or not a country code alias is used as the template parameter.
  • {{flag country|Peru}} → Peru
  • {{flag country|PER}} → Peru
• Template:Flag decoration displays an unlinked flag icon without country name.
  • {{flag decoration|Peru}} →

Alternatives to avoid Wikipedia's Post-expand include size limit

Pages with many flag icons may come close to or exceed Wikipedia's Post-expand include size limit. In these cases consider using modules or module-wrapper templates instead:

• {{flagg}} is a simple wrapper for Module:Flagg: For basic use, {{flag icon|country}} can be replaced with {{flagg|cxxlo|country}}
• {{#invoke:flag|icon}} is a wrapper for Module:Flagg that can further reduce sizes when invoked directly. For basic use, {{flag icon|country}} can be replaced with {{#invoke:flag|icon|country}}.
