This plugin was build of the fantastic Advanced Custom Fields plugin created by Elliot Condon, and was made so that referencing custom fields is easier. Here, you can see a full list of all your currently used field which is sortable by clicking on the headers, and should you need to learn more about the field or edit it, clicking the label name will take you to the field group’s page so you can do what you need to. The table sorting functionality incorporates the Tablesorter jQuery plugin by Christian Bach. Docs can be found at http://tablesorter.com/docs/.
*Note: This doesn’t display fields in your theme. It just gives you a complete list of your fields that you can reference easily and allows you to edit the field groups easily.
I tried to mark up the code for this plugin with lots of comments in hope that people can understand how it is working and expand on this functionality. Oh yeah, and all the function and variable names are based off Buster Bluth from Arrested Development.

This plugin allows references and citations in your posts. It’s only a beta version, so if you find issues or if you think it lacks some features, please contact me.
To use it, simply add your reference using a shortcode you can choose (‘jref’ by default), and a few attributes (always use lowercase):
<ul>
<li>title (mandatory)</li>
<li>author</li>
<li>date</li>
<li>url</li>
<li>editor</li>
<li>page</li>
<li>lang</li>
<li>readon</li>
</ul>
There are no specific controls on the content of those attributes, you may add any text you want. Only ‘title’ is mandatory. All attributes roles are easy to understand; ‘page’ is for a book (but can be used for any content), ‘readon’ is the date you last consult the reference.
Again, in this first release, there’s no specific control or action triggered by attribute’s content (like verifying the format, or linking to an archive site). Maybe in a future release…
A list of all references will be added at the end of the post.
Here are some examples:
<ul>
<li>[jref]url=http://geba.fr|date=janv 2017|title=The Title.|author=Janiko|lang=FR|editor=geba.fr|page=p.5[/jref]</li>
<li>[jref name=’numref’]url=http://geba.fr|date=janv 2017|title=The Title.|author=Janiko|lang=FR|editor=geba.fr|page=p.5[/jref]</li>
<li>[jref name=’numref’ /]</li>
</ul>
You can optionnaly add a name to the citation, so you can reuse it in your post. Important note: the displayed attributes will be the attributes of the FIRST reference with that name. Any other attribute will be ignored.

JReferences

This plugin adds references and citations functionalities (in a wikipedia-like style).
