سانچہ:Refn

دستاویز [نمائش] [ترمیم] [تاریخچہ] [تطہیر]

Purpose

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.

Usage

{{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.)

Substitution

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}}.

مارک اپ	بطور نتیجہ
<ref>{{حوالہ ویب|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> {{حوالہ جات}}
{{refn|{{حوالہ ویب|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}}}} {{حوالہ جات}}

Errors

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:

مارک اپ	بطور نتیجہ
{{refn|1+1=2}}
{{refn|1= 1+1=2}}
