The Citation template generates a citation for a book, periodical, contribution in a collective work, patent, or a web page. It determines the citation type by examining which parameters are used. As with other citation templates, this template can be used either in a footnote (between <ref>...</ref> tags) or in a section that lists sources. This template uses the same Lua code as citation style 1 (CS1) templates with parameters to change the displayed format to citation style 2 (CS2).

If the correct parameters are used, this template produces output identical to that of the Cite templates, such as {{Cite book}} and {{Cite web}}, with one important exception: By default, this Citation template uses commas in places where the Cite templates use periods (full stops) by default; either type of template can use periods (full stops) or commas by using an optional parameter. Also, this template by default generates anchors for Harvard references whereas the Cite templates by default do not (although they can be made to do so).

Regardless of which citation templates are used or even if none are used at all, all citations should have the same format throughout an article in the saved, rendered text.

Note: All parameter names must be lowercase.

การอ้างอิงอย่างง่าย[แก้]

This section covers the most commonly used parameters. You can copy the horizontal form or vertical form below and then add in extra parameters from the full list. Spacing and ordering of the parameters within the template is irrelevant and does not affect the final, rendered text.

  • last: The author's surname or last name. Don't use with the author parameter.
  • first: The author's first or given name(s).
  • year: Year of authorship or publication. Mandatory for use with links from Template:Harvard citation, unless |date= specifies both month and year.
  • title: Title of the work. Mandatory for web references.
  • publisher: The name of the publisher. Omit terms such as Publishers, Co., Inc., Ltd., etc., but retain the words Books or Press. Not normally included where the publication is a periodical which has its own Wikipedia article (e.g. Newsweek, Billboard).
    • publication-place (or place or location): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. Omit when the publication is a periodical whose name specifies the location (e.g. The New York Times, The Times of India)
  • page: For use when one page is cited. Adds "p." before the page number. Do not use with pages.
  • url: A url of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
    • accessdate: Date[n 1] when the url was accessed.

Nested parameters rely on their parent parameters:

  • parent
  • OR: parent2—may be used instead of parent
    • child—may be used with parent (and is ignored if parent is not used)
    • OR: child2—may be used instead of child (and is ignored if parent2 is not used)
Where aliases are listed, only one of the parameters may be defined; if multiple aliased parameters are defined, then only one will show.

รายละเอียด[แก้]

ผู้แต่ง[แก้]

  • last: Surname of a single author. Do not wikilink—use author-link instead. For corporate authors or authors for whom only one name is listed by the source, use last or one of its aliases (e.g. |author=Bono). Aliases: surname, author, last1, surname1, author1.
    • author: this parameter is used to hold the complete name of a single author (first and last) or to hold the name of a corporate author. This parameter should never hold the names of more than one author.
    • first: Given or first names of author; for example: Firstname Middlename or Firstname M. or Firstname M. Sr. Do not wikilink—use author-link instead. Aliases: given, first1, given1. Requires last; first name will not display if last is empty. Use generational and แม่แบบ:Notatypo suffixes only in accordance with MOS:JRSR and use honorifics only in accordance with MOS:HON.
    • OR: for multiple authors, use last1, first1 through lastn, firstn, where n is any consecutive number for an unlimited number of authors (each firstn requires a corresponding lastn, but not the other way around). See the display parameters to change how many authors are displayed. Aliases: surname1, given1 through surnamen, givenn, or author1 through authorn. For an individual author plus an institutional author, you can use |first1=...|last1=...|author2=....
    • author-link: Title of existing Wikipedia article about the author—not the author's website; do not wikilink. Aliases: author-link1, author1-link, authorlink.
    • OR: for multiple authors, use author-link1 through author-linkn. Aliases: author1-link through authorn-link.
    • name-list-style: accepts a limited list of keywords as value; when set to amp, ampersand, or &, inserts an ampersand between the last two names in a name list; when set to and, inserts the conjunction 'and' between the last two names of a name list; when set to vancdisplays name lists in Vancouver style when the lists use the last/first forms of name parameters.
  • vauthors: comma-separated list of author names in Vancouver style; enclose corporate or institutional author names in doubled parentheses. End with etal if appropriate:
    |vauthors=Smythe JB, ((Megabux Corp.)), etal
    • author-link and author-mask may be used for the individual names in |vauthors= as described above
  • authors: Free-form list of author names; use of this parameter is discouraged because it does not contribute to a citation's metadata; not an alias of last.
  • translator-last: Surname of translator. Do not wikilink—use translator-link instead. Aliases: translator-surname, translator1, translator1-last, translator-last1.
    • translator-first: Given or first names of translator. Do not wikilink—use translator-link instead. Aliases: translator-given, translator1-first, translator-first1.
    • OR: for multiple translators, use translator-last1, translator-first1 through translator-lastn, translator-firstn, where n is any consecutive number for an unlimited number of translators (each translator-firstn requires a corresponding translator-lastn, but not the other way around). Aliases: translator1-last, translator1-first through translatorn-last, translatorn-first, or translator1 through translatorn.
    • translator-link: Title of existing Wikipedia article about the translator—not the translator's website; do not wikilink. Aliases: translator-link1, translator1-link.
    • OR: for multiple translators, use translator-link1 through translator-linkn. Aliases: translator1-link through translatorn-link.
  • collaboration: Name of a group of authors or collaborators; requires author, last, or vauthors listing one or more primary authors; follows author name-list; appends "et al." to author name-list.
  • others: To record other contributors to the work, including illustrators. For the parameter value, write Illustrated by John Smith.
  • Note: When using เชิงอรรถอย่างย่อ or การอ้างอิงในวงเล็บ styles with templates, do not use multiple names in one field, or else the anchor will not match the inline link.

ชื่อเรื่อง/หัวเรื่อง[แก้]

(See also Help:Citation Style 1 § Titles and chapters.)

  • title: Title of source. Can be wikilinked to an existing Wikipedia article or url may be used to add an external link, but not both. Displays in italics. If script-title is defined, use title to hold a Romanization (if available) of the title in script-title.
    • script-title: Original title for languages that do not use a Latin-based script (Arabic, Chinese, Cyrillic, Greek, Hebrew, Japanese, Korean, etc.); not italicized, follows italicized Romanization defined in title (if present). Must be prefixed with one of the supported language codes to help browsers properly display the script:
      ... |title=Tōkyō tawā |script-title=ja:東京タワー |trans-title=Tokyo Tower ...
    • trans-title: English translation of the title if the source cited is in a foreign language. Displays in square brackets after title. Use of the language parameter is recommended.
Titles containing certain characters will not display and link correctly unless those characters are encoded.
newline [ ] |
space &#91; &#93; {{!}} (preferred)
{{bracket|text}} &#124; or {{pipe}}see also Help:Table § Rendering the pipe
  • title-link: Title of existing Wikipedia article about the source named in title – do not use a web address; do not wikilink.

แม่แบบ:Citation Style documentation/chapter แม่แบบ:Citation Style documentation/type

  • language: The language (or a comma-separated list of the languages) in which the source is written, as either the ISO 639 language code (preferred) or the full language name. Examples: |language=ru; |lang=fr, pt-br; |lang=รัสเซีย; |language=ฝรั่งเศส, โปรตุเกส. See the list of supported codes and names. Do not use templates or wikilinks. Displays in parentheses with "in" before the language name or names. When the only source language is English, no language is displayed in the citation. The use of languages recognized by the citation module adds the page to the appropriate subcategory of หมวดหมู่:CS1 แหล่งที่มาภาษาต่างประเทศ. Because cs1|2 templates are often copied from en.wiki to other wikis, the use of language codes is preferred so that language names render in the correct language and form: espagnol at a French-language wiki instead of the English word "Spanish". Aliases: lang

วันที่[แก้]

  • date: Date of source being referenced. Can be full date (day, month, and year) or partial date (month and year, season and year, or year). Use same format as other publication dates in the citations.[date 1] Required when year is used to disambiguate {{sfn}} links to multiple-work citations by the same author in the same year.[more] Do not wikilink. Displays after the authors and is enclosed in parentheses. If there is no author, then displays after publisher. For acceptable date formats, see Help:Citation Style 1 § Dates.
For approximate year, precede with "c. ", like this: |date=c. 1900.

For no date, or "undated", add as |date=n.d.
  • year: Year of source being referenced. Use of |date= is recommended unless all of the following conditions are met:
    1. The template uses |ref=harv, or the template is {{citation}}, or |mode=cs2
    2. The |date= format is YYYY-MM-DD.
    3. The citation requires a CITEREF disambiguator.
  • orig-year: Original publication year; displays after the date or year. For clarity, please supply specifics. For example: |orig-year=First published 1859 or |orig-year=Composed 1904. Alias: origyear
  • df: date format; sets rendered dates to the specified format; does not support date ranges or seasonal dates. Accepts one value which may be one of these:
    dmy – set publication dates to day month year format; access- and archive-dates are not modified;
    mdy – as above for month day, year format
    ymd – as above for year initial numeric format YYYY-MM-DD
    dmy-all – set publication, access-, and archive-dates to day month year format;
    mdy-all – as above for month day, year format
    ymd-all – as above for year initial numeric format YYYY-MM-DD
  1. Publication dates in references within an article should all have the same format. This may be a different format from that used for archive and access dates. See MOS:DATEUNIFY.

การอ้างอิงแบบปักหมุด (anchored citations)[แก้]

This template can generate a citation that can be combined with shortened footnotes or parenthetical referencing. It does this by creating an HTML anchor containing an ID. The special parameter |ref=harv generates an ID suitable for Harvard referencing templates such as {{harv}} as specified in the next section; this is the default for the {{citation}} template.

To disable anchor generation, specify |ref=none (in contrast, other Cite templates such as {{cite book}} and {{cite news}} do not create an anchor by default). You can also specify the ID directly, using the |ref=ID parameter. For example, suppose an article's References section contains the markup:

  • {{Citation |author=Sigmund Freud |title=Civilization and Its Discontents |year=1930 |ref=CivDis}}

which generates the citation:

  • Sigmund Freud (1930), Civilization and Its Discontents

Then, the markup "([[#CivDis|Freud 1930]])" generates a parenthetical reference "(Freud 1930)" containing a wikilink to the citation (try clicking on the wikilink).

Anchors for Harvard referencing templates[แก้]

IDs compatible with Harvard referencing templates such as {{harv}} are computed from the last names of the authors (or editors, if no authors are given) and the year of the cited source. For example, the markup "{{harv|Wright|Evans|1851|p=ix}}" generates the Harvard reference "(Wright & Evans 1851, p. ix)", which wikilinks to the citation whose markup and appearance are shown below:

  • {{Citation |last1=Wright |first1=Thomas |last2=Evans |first2=R. H. |title=Historical and Descriptive Account of the Caricatures of James Gillray |location=London |publisher=Henry G. Bohn |year=1851 |oclc=59510372}}
  • Wright, Thomas; Evans, R. H. (1851), Historical and Descriptive Account of the Caricatures of James Gillray, London: Henry G. Bohn, OCLC 59510372

In this example the {{citation}} template defines, and the {{harv}} template uses, the HTML ID "CITEREFWrightEvans1851", composed by concatenating the string "CITEREF" with the last names of the authors and the year. The {{harvid}} template can be used to generate such IDs, for example, {{harvid|Wright|Evans|1851}} generates "CITEREFWrightEvans1851".

Related methods which leave only a number in the text are to use the {{harvnb}} template enclosed in the <ref></ref> html code, or to use the {{sfn}} template alone. The example above would be <ref>{{harvnb|Wright|Evans|1851|p=ix}}</ref> or {{sfn|Wright|Evans|1851|p=ix}} both of which generate a footnote, such as

17. Wright & Evans 1851, p. ix

The names of only the first four authors are used; other author names are not concatenated to the ID. If no author names are given, editor names are used instead. For patents, inventor names are used instead of authors or editors. If these names are not given, this template does not generate an anchor.

Last names are used, as specified by the parameters |last1= (or |last=), |last2=, |last3=, and |last4=, and similarly for |editor1-last= etc. and for |inventor1-last= etc. If a full name is given but no last name is specified, this template falls back on the full name, but this usage is not recommended. For example, in "{{Citation | author = Sigmund Freud | title = The Ego and the Id | year = 1923}}" no last name is given, so this citation cannot be combined with the Harvard reference "{{harv|Freud|1923}}". To make these {{citation}} and {{harv}} invocations compatible, either replace "|author=Sigmund Freud" with "|first=Sigmund |last=Freud", or add "|ref={{harvid|Freud|1923}}" to the {{citation}} invocation, or add the same ref parameter (say, "|ref=EgoId") to both the {{citation}} and the {{harv}} invocations.

Similarly, the year is used, as specified by |year=. If no year is given, this template attempts to derive the year from |date= (or, if no date is given, from |publication-date=) by applying the MediaWiki § Time function. This heuristic works with many common date formats (American, International and ISO 8601 standard format YYYY-MM-DD as listed in WP:MOS), but may not work as expected with other formats, so when in doubt it may be safer to use |year=. Note that if only a year, say 2005, is known you must use |year=2005 rather than |date=2005.

IDs must be unique[แก้]

Names, years, and hand-specified IDs must be chosen so that the IDs are unique within a page; otherwise the HTML will not conform to the W3C standards, and any references to the citations will not work reliably. For example, suppose a page contains the following two citations with {{harv}}-compatible IDs:

If these citations were altered to say "2008" rather than "2008a" and "2008b", the resulting page would not work, because the two different citations would both attempt to use the ID "CITEREFMontesHalterman2008". To avoid this problem, distinguish the citations by appending suffixes to the years, e.g. "|year=2008a" and "|year=2008b", as was done above. Any Harvard references to these citations should use years with the same suffixes.

It is good practice to verify that a page does not contain duplicate IDs by using the W3C Markup Validation Service; see External links.

วันที่[แก้]

  1. The format of dates in the references of an article should use consistent and unambiguous styles. Example formats used in Wikipedia citations include: Dates should not be linked (say, to a Wikipedia article of the same name) in references. Please see Wikipedia:Manual of Style (dates and numbers) § Dates for more guidance about formatting dates.

เครื่องมือ[แก้]

See Wikipedia:Citing sources § Citation templates and tools for a list of tools that can help create a reference in the "citation" format.

Author Maskauthor-mask authormask

Replaces the name of the first author with em dashes or text. Set author-mask to a numeric value n to set the dash n em spaces wide; set author-mask to a text value to display the text without a trailing author separator; for example, "with". You must still include the values for all authors for metadata purposes. Primarily intended for use with bibliographies or bibliography styles where multiple works by a single author are listed sequentially such as shortened footnotes. Do not use in a list generated by {{reflist}}, <references /> or similar as there is no control of the order in which references are displayed. You can also use editor-mask and translator-mask in the same way.
