Plugin: footnotes-for-wordpress (Used by 75 domains)

Footnotes for WordPress is a simple plugin designed with a simple aim in mind: to make
it dead-easy to include decently-formatted footnotes in posts and pages on your
WordPress blog.

The syntax is roughly based on the common MediaWiki syntax for footnotes, but uses the
WordPress shortcode conventions. So, to include a footnote with the text “Text,” you use:

This is footnoted.[ref]Text[/ref]

And that’s all you need to do. When you add a footnote, Footnotes for WordPress will
create a note marker at the point that the foonote appears in the text, and includes
the text of the footnote in a styled list of notes down the page. When a reader clicks
on the link in a JavaScript-enabled browser, a script included with the plugin will
create a small bubble inline in the text, which pops up over the footnote marker for
easy reading without losing their place. In non-JavaScript-enabled contexts, clicking
on the footnote marker jumps down the page to the text of the note.

The jump is based on an unique anchor which the plugin can automatically generate for
you. However, if you want to create a specific ID of your own for the footnote, you
can do so using the name="..." attribute:

This is footnoted.[ref name="my-unique-id-1"]Text[/ref]

If you define an ID for a footnote, you can also refer back to the same footnote
later on in the document, using the [backref name="..."] shortcode.

This is footnoted.[ref name="source1"]Source 1[/ref]

So is this.[ref name="source2"]Source[/ref]

And this one comes from the same source as the first.[backref name="source1"]

Footnotes are numbered, beginning at 1. However, you can change the numbering if you
so desire using the number="..." attribute. For example, I often use this when
quoting from a book that contains footnotes or endnotes, in order to represent the
notes used by the original text.

This is footnoted, but footnotes begin at number 42.[ref number="42"]...[/ref]

You can change the text that is displayed in the note’s superscripted link from the
note’s number to any text or symbol that you choose using the superscript="..."
attribute. For example, to use an asterisk instead of the note number:

This is footnoted with a good old asterisk.[ref superscript="*"]...[/ref]

By default, the list of footnotes appears at the bottom of the post. However, if you
wish them to appear somewhere above the bottom of the post, for formatting or other
reasons, you can do so using the [references/] shortcode:

This is footnoted.[ref]Text[/ref]

As are some[ref]Text[/ref] other things.

[references/]

See also: Endnotes.

Which will cause the two footnotes to appear beneath the second paragraph but above
the “See also:” text.

Usage

• To create a footnote, use [ref]...[/ref] to wrap the text of your note.

  Example: This is footnoted.[ref]This is the text of the of the footnote.[/ref]

• Normally footnotes use numbered superscripts to indicate the footnote, beginning
  with 1. You can choose to use symbols instead, like *, **, †, etc. To use custom
  text for a footnote’s superscript, use [ref superscript="*"]...[/ref], and
  replace the asterisk with whatever symbol or text you want to use.

• Normally footnotes begin at 1 and count up towards infinity. If you want to use
  numbered subscripts but need to reset the number they count from, use the number
  attribute. For example, if you want the current subscript to be numbered 128, and
  for subsequent subscripts to be numbered 129, 130, etc., use:
  [ref number=”128″]…[/ref].

• To create a footnote with a specific unique ID, instead of the one that the plugin
  will automatically generate for you, use [ref name="..."]...[/ref]

  Example: This is footnoted.[ref name="my-unique-id"]This is the note text.[/ref]

• If you define an ID for a footnote, you can also refer back to the same
  footnote later on in the document, using the [backref name="..."]
  shortcode.

  This is footnoted.[ref name=”source1″]Source 1[/ref]

  So is this.[ref name=”source2″]Source[/ref]

  And this one comes from the same source as the first.[backref name=”source1″]

• To force the plugin to display notes at a different location instead of at the bottom
  of the post, use [references/]

  Example:

  This is footnoted.[ref]Text[/ref]

  As are some[ref]Text[/ref] other things.

  [references/]

  See also: Endnotes.

• If you wish to change how footnotes are styled, you can alter them in your
  WordPress theme stylesheet, or using JavaScript. The default elements and
  classes are for superscript links to footnotes,

    ol.footnotes li {
        background: transparent !important;
        padding: 0px !important;
        border: none !important;
        margin: 0.5em 2em !important;
    }

The use of `!important` will ensure that it overrides the default styles
set up by the plugin.

• Alternatively, if you want to change the CSS class which is applied to to
  the footnotes list, you can do so using the class parameter on
  [references/]:

  This is a test.[ref]Lewis (2000).[/ref]
  
  Notes
  
  [references class="compact" /]
  

  … which will produce the following HTML:

  This is a test.[]
  
  Notes
  
  [1] Lewis
  (2000). ↩
  

  Since the default styling is based on children of ol.footnotes, those
  styles will not apply, and you can apply whatever styles you wish to the
  class that you’ve created.
