Multi parts posts

This plugin has been deprecated. See the series plugin for a better support of multi part articles.

The multi-part posts plugin allow you to write multi-part posts.

In order to mark posts as part of a multi-part post, use the :parts: metadata:

:parts:  MY_AWESOME_MULTI_PART_POST

You can then use the article.metadata.parts_articles variable in your templates to display other parts of current post.

For example:

{% if article.metadata.parts_articles %}
    <p>This post is part of a series:</p>
    <ol class="parts">
        {% for part_article in article.metadata.parts_articles %}
            <li {% if part_article == article %}class="active"{% endif %}>
                <a href='{{ SITEURL }}/{{ part_article.url }}'>{{ part_article.title }}</a>
            </li>
        {% endfor %}
    </ol>
{% endif %}
