Editing Template:Further information/doc

{{documentation subpage}}
{{lua|Module:Further}}

This template is used to link to articles containing further information on a topic. It looks like this:

{{further|Article}}

It is typically used at the top of a section, when the topic of that section is covered in more detail by another page.

== Usage ==

; Basic usage:
 &#123;{further|''page1''|''page2''|''page3''|...}}

; All parameters:
 &#123;{further|''page1''|''page2''|''page3''|...|selfref=''yes''|category=''no''}}

== Parameters ==

This template accepts the following parameters:
* <code>1</code>, <code>2</code>, <code>3</code>, ... - the pages to link to. At least one page name is required. Categories and files are automatically escaped with the [[w:Help:Colon trick|colon trick]], and links to sections are automatically formatted as ''page § section'', rather than the MediaWiki default of ''page#section''.
* <code>category</code> - if set to "no", "n", "false", or "0", suppresses the error tracking category ([[:Category:Hatnote templates with errors]]). This only has an effect if the first positional parameter (the page to link to) is omitted.

== Examples ==

* <code><nowiki>{{further|Article}}</nowiki></code> → {{further|Article}}
* <code><nowiki>{{further|Article1|Article2|Article3}}</nowiki></code> → {{further|Article1|Article2|Article3}}

== Errors ==

If no page names are supplied, the template will output the following message:
* {{further|category=no}}

If you see this error message, it is for one of four reasons:
# No parameters were specified (the template code was <code><nowiki>{{further}}</nowiki></code>). Please use <code><nowiki>{{further|</nowiki>''page''<nowiki>}}</nowiki></code> instead.
# Some parameters were specified, but no page names were included. For example, the template text <code><nowiki>{{further|selfref=yes}}</nowiki></code> will produce this error. Please use (for example) <code><nowiki>{{further|</nowiki>''page''<nowiki>|selfref=yes}}</nowiki></code> instead.
# A page name was specified, but it contains an equals sign ("="). The equals sign has a special meaning in template code, and because of this it cannot be used in template parameters that do not specify a parameter name. For example, the template code <code><nowiki>{{further|1+1=2|2+2=4}}</nowiki></code> will produce this error. To work around this, you can specify the parameter name explicitly by using <code>1=</code>, <code>2</code>, etc., before the page name, like this: <code><nowiki>{{further|1=1+1=2|2=2+2=4}}</nowiki></code>.
# You tried to access [[Module:Further]] directly by using <code><nowiki>{{#invoke:further|further|</nowiki>''text''<nowiki>}}</nowiki></code>. Use of #invoke in this way has been disabled for performance reasons. Please use <code><nowiki>{{further|</nowiki>''text''<nowiki>}}</nowiki></code> instead.

If you see this error message and are unsure of what to do, please post a message on [[WP:HD|the help desk]], and someone should be able to help you.

Pages that contain this error message are tracked in [[:Category:Hatnote templates with errors]].
