Footnotes module can be used to easily create automatically numbered footnote references into an article or post (such as a reference to a URL). It now supports also TinyMCE and CKEditor via WYSIWYG module.

ABOUT FOOTNOTES

The Footnotes module can be used to create automatically numbered footnotes within a text. In the place where you want to add a footnote enclose the footnote text within an fn tag: [fn]like this[/fn]. By default, footnotes are placed at the end of the text. You can also use a [footnotes] or [footnotes /] tag to position it anywhere you want.

The filter will take the text within the tag and move it to a footnote at the bottom of the page. In it's place it will place a number which is also a link to the footnote. Footnotes supports both [fn]square brackets[/fn] and <fn>angle brackets</fn>.

You can also use a "value" attribute to a) set the numbering to start from the given value, or b) to set an arbitrary text string as label.
Ex:

[fn value="5"]This becomes footnote #5. Subsequent are #6, #7...[/fn]
[fn value="*"]This footnote is assigned the label "*"[/fn]

Using value="" you can have multiple references to the same footnote in the text body.

[fn value="5"]This becomes footnote #5.[/fn]
[fn value="5"]This is a reference to the same footnote #5, this text itself is discarded.[/fn]

Since 2.4 Footnotes supports both TinyMCE and CKEditor via plugins to the WYSIWYG module. They each work slightly differently, please see the README for those plugins to learn more.

Version 2.4 introduces an optional feature that identical footnotes are
collapsed into one, as if they had the same value="" attribute. This must be enabled from admin/settings/filters by choosing the relevant "Input format" and then the "Configure" tab. By default, footnotes are separate unless you specify them to have the same value="" attribute.

TEXTILE FILTER

The Textile variant of Footnotes is now removed in 7.x-2.5. You can use the standard [fn]...[/fn] filter also together with Textile notation.

BETTER URL FILTER

The Footnotes module also used to ship a "Better URL filter". This code has now been committed to Drupal core and you can use it from there as the regular URL filter. Better URL filter has been removed from the 7.x-2.x version of footnotes.

INSTALL INSTRUCTIONS FOR FOOTNOTES.MODULE

1. Copy the contents of this module to sites/all/modules/footnotes folder.
2. Login as site administrator.
3. Activate footnotes on the administer->modules page.
4. To use the footnotes filter in some input formats, go to Configuration ->
Text formats.
5. For the Text formats you want to support footnotes markup, select configure
and activate a suitable footnotes filter.

TIPS n TRICKS (CSS)

Many Footnotes users don't want the footnotes to show in teasers (such as the front page listing). The correct way to prevent that is by using CSS. See #209037: Exclude foot notes in teasers for examples.

Beginning with version 2.4, Footnotes will highlight the footnote text if you click on the footnote reference link. (This was inspired by wikipedia, see #728658: Highlight footnote when clicking the link). The highlight color is light gray. If this clashes with your site's colors, or you want to set a nicer color (or unset the feature altogether) you need to override the default color in your own theme. The below CSS can be used for that:

.see_footnote:target,
.footnotes .footnote:target {
  background-color: #ffeeee; /* Set footnote highlight color to light pink. */
}
.see_footnote:target {
  border: solid 1px #ffaaaa; /* Set border color of highlighted footnote ref to
light red. */
}

As part of this feature, CSS class names have moved tags. While unlikely, if you have used these in your own themes, please change your CSS accordingly:

  • The "footnote" class used to be the A or SPAN element that is the footnote number/label in the list of footnotes. This class is now the LI element containing the entire footnote.
  • The A or SPAN element now has the class "footnote_label"

Due to changes in HTML and CSS, you need to clear the Drupal cache after upgrading to version 2.4 or later.

HTML FILTER

Footnotes.module is designed such that it can be used together with Drupal's html filter, and in particular you should have footnotes first and html filter later.

This version of Footnotes has been redesigned so that it only outputs html tags that are allowed in a default installation of HTML filter. (Tags used are A, UL and LI.)

KNOWN ISSUES

Version 2.0 uses a new markup for the list of footnotes. It is an UL list with CSS taking away the browser generated list bullets and moving the link numbers towards the left instead. All IE versions have a bug that the numbers are slightly lower than the baseline of the footnote text. (If you know how to fix this, please tell.) In addition IE 5.5 has a more serious bug that the footnote number will be on top of the first letters of the footnote text. There doesn't seem to be a way to fix this.

The Views API functionality only works in the common use case when footnotes are at the end of the text, but does not work correctly when using [footnotes] tag explicitly. See #1003690: footnotes_views should take into account that the footnotes needn't be at the end. to follow up on this bug.

The Views module is not yet ported to Drupal 7 and consequently also Footnotes Views cannot be ported.

Footnotes.module was originally created by henrik.ingo@avoinelama.fi ("hingo" on drupal.org) in the summer of 2006.

The HTML footnotes were seriously enhanced by "beginner" (on drupal.org) and later on by other users comments and code snippets.

Footnotes was originally developed for http://openlife.cc/onlinebook

Beginner was the second to use it on his site at

I wish to thank all contributors for letting me experience the miracle of maintaining an Open Source module living its own life!
