Footnotes

About

This plugin adds a footnote button to Redactor fields. Also, it adds new filters and functions to your Twig templates. — In the end you get what the plugin's name already says: Footnotes.

Features

• coexists with regular ^superscript texts that are not supposed to be footnotes
• numbers referring to footnotes can be anchor links → see instructions of plugin settings in screenshot below or see the setting in action
• identical footnote texts can either be listed as one footnote or separately → see instructions of plugin settings in screenshot below or see the setting in action

Implementing Twig templates

When "Enable anchor links" setting is off

{# render your Redactor field's contents while filtering all footnotes #}
{{ entry.textField | footnotes }}

{# render all collected footnotes #}
{% if footnotes_exist() %}
    <ul>
        {% for number, footnote in footnotes() %}
            <li>
                {{ number }} {{ footnote }}
            </li>
        {% endfor %}
    </ul>
{% endif %}
