سانچہ:Refn

This template is used to create footnotes in Wikipedia, as an alternative and complement to the <ref>. Because of a technical limitation, some of the standard Wikipedia markup elements that are often used in the article prose do not work within a set of <ref>...</ref> tags, including but not limited to the pipe trick, template substitution and another "nested" set of <ref>...</ref> tags. For example, the following does not work as expected:

1. <ref>[[Help:Footnotes|]]</ref> (Generates: [[Help:Footnotes|]] instead of a wikilink)
2. <ref>{SUBST:TODAY}</ref> (Generates: {SUBST:TODAY} instead of the date that the edit was made)
3. <ref>Explanatory footnote<ref>Citation</ref></ref> (Generates: Cite error: A <ref> tag is missing the closing </ref> (see the help page). </ref>)

Replacing the outermost <ref>...</ref> set with {Refn} allows for the use of the markup elements listed above.

{refn|group=groupname|name=name|Contents of the footnote}

• groupname: Groupname per WP:REFGROUP; if not specified, then the main and nested references will be rendered into the same reference list
• name: Reference name per WP:REFNAME

Names for footnotes and groups must follow these rules:

• Names are case-sensitive
• Names may not be purely numeric
• Names must be unique—you cannot use the same name to define different groups or footnotes
• Quotes are optional if the only characters used are letters A–Z, a–z, digits 0–9, and the symbols !$%&()*,-.:;<@[]^_`{|}~
• Inclusion of any other characters, including spaces, requires that the name be enclosed in quotes (")
• The quote marks must be the standard straight keyboard marks ("); curly or other quotes will be parsed as part of the reference name.
• Quote-enclosed names may not include a less-than sign (<) or a double straight quote symbol (")
• Please consider keeping names simple and restricted to the standard انگریزی حروف تہجی and numerals.
• (You may optionally provide names even when the name is not required.)

An example.{refn|group=note|name=first|A note.<ref>An included reference.</ref>}
Another example.{refn|group=note|Another note.<ref>Another included reference.</ref>}
A third example.{refn|group=note|The third note.<ref>The reference in the third note.</ref>}
Repeating the first example.{refn|group=note|name=first}

An example.{refn|group=note|name=first|A note.<ref>The reference in the first note.</ref>}
Another example.{refn|name=ref|Another reference, but without a note.}
A third example.{refn|group=note|A second note.<ref>The reference in the second note.</ref>}
Repeating the first example.{refn|group=note|name=first}
Repeating the second example.{refn|name=ref}
A fourth example with citation templates.{refn|name=harv|{cite book|author=Smith|title=The Solar System|year=2005|mode=cs2}, quoted in {harvnb|Jones|2020|p=25}.}

==Notes==
{reflist|group=note}

{reflist}

The first example shows that substitution does not work in a regular <ref>...</ref> tag (the |access-date= does not appear correctly). The second example shows that the |access-date= is substituted correctly within {refn}.

<ref>{cite web |access-date={Subst:TODAY} |title=Languages |work=Apache HTTP Server |agency=Ohloh |publisher= Black Duck Software |url=https://www.ohloh.net/p/apache/analyses/latest/languages_summary}</ref>
{reflist}

{refn|{cite web |access-date={Subst:TODAY} |title=Languages |work=Apache HTTP Server |agency=Ohloh |publisher= Black Duck Software |url=https://www.ohloh.net/p/apache/analyses/latest/languages_summary}
{reflist}

If the reference or note content is missing, then Cite error: Invalid <ref> tag; refs with no name must have content. will be displayed.

If the note content contains an equals sign (=), the equals sign will be interpreted as setting off a named parameter and cause an error. This can be worked around by using a numbered parameter, for example:

{refn|1+1=2}

{refn|1= 1+1=2}
