The plugin includes three major components: (1) a PHP module which implements easy-to-use shortcodes for footnotes in FeedWordPress; (2) a small JavaScript module which allows JavaScript-enabled browsers to display the footnote in a small bubble that pops up over the footnote reference, for easy reading; and (3) a stylesheet and small collection of images, which control the default appearance of footnote references, the content of footnotes, and the content of footnotes when displayed inline. The plugin makes extensive use of CSS classes to determine the appearance of the footnotes, meaning that you can override it with your own favored appearance from within your WordPress theme’s stylesheets.

Installation: Installation is designed to be dead simple. Download the installation package, install the contents in the plugins directory of your WordPress website, and activate the plugin from within the WordPress Plugins control panel. The plugin should begin working automatically as soon as it is activated.

Usage: Shortcodes are based on MediaWiki’s syntax for footnotes. To create a footnote, you can use the following WordPress shortcode:

This text is footnoted.[ref]With this footnote[/ref]

The plugin will automatically generate a unique HTML ID for each footnote that you add. However, if you wish to set a specific HTML ID of your own, you can use the name="..." parameter:

You can make the plugin generate IDs
with different names.[ref name="any-id-you-please"]Any IDs you
please![/ref]

By default, the plugin will automatically place all footnotes at the end of your post. If you want to display the footnote content somewhere else in the post (for example, because you want to place it above a list of “see also” likes), you can do so using the [references/] shortcode:

This text is footnoted.[ref]With
this footnote.[/ref]
     
And our footnotes will appear here:

[references/]

<h3>See also:</h3>

<li><a href="http://example.com/1/">Post 1</a></li>
<li><a href="http://example.com/2/">Post 2</a></li>
</ul>

Download and enjoy! As always, if you have any issues with the release, or if there is anything that you would like to see included in a future release, please use the comments form or drop me a line to let me know about it.
