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.

The WordPress plugin is a Block Editor Widget that displays a random quote from the collection of the user community <a href="https://www.zitat-service.de/en" rel="nofollow ugc">zitat-service.de/en</a>. The selection of quotes comes from the five languages German 🇩🇪, English 🇬🇧, Spanish 🇪🇸, Japanese 🇯🇵 or Ukrainian 🇺🇦. We have been online free of charge and without advertising since 2007.
Detailed instructions on installation and configuration can be found in the <a href="https://github.com/muhme/quote_wordpress/wiki" rel="nofollow ugc">wiki</a>.
There is a WordPress demo installation with plugin Random Quote from Zitat-Service running online at <a href="https://wp-demo.zitat-service.de" rel="nofollow ugc">wp-demo.zitat-service.de</a>.
<h3>Usage of External API.zitat-service.de</h3>
The WordPress plugin fetches all data from <a href="https://api.zitat-service.de" rel="nofollow ugc">api.zitat-service.de</a>. Terms of use and privacy statement can be found in the <a href="https://www.zitat-service.de/en/start/contact" rel="nofollow ugc">Imprint</a>.
The random quotes of the WordPress website (frontend) are retrieved by PHP code running on the WordPress server (backend). This means that the process of retrieving quotes does not involve tracking or recording any user-specific data. Instead, it operates within the server environment, ensuring user privacy and compliance with guidelines that prohibit tracking users without their consent.
The displayed quotes, along with their respective authors and sources, are linked externally to websites such as zitat-service.de and Wikipedia to provide users with additional context and information. All external links are activated only after manual verification by the admin team at zitat-service.de, ensuring the reliability and accuracy of the linked content.
