Pang-bô͘:Refn

Pang-bô͘ bûn-su[chhâ-khòaⁿ] [pian-chi̍p] [le̍k-sú] [kun-sin]

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 Pang-bô͘:Tlp 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

Pang-bô͘:Refname rules

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}

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

==References==
{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}

Pang-chān:Footnotes

• {r} (another template supporting nested footnotes)
• {citeref} (a different method to create nested links working on citation template anchor level rather than <ref></ref> markup level)
