In this series of articles, I am going to introduce each of the plugins I have developed for ClassicPress, a hard-fork of WordPress, which was originally created to provide an alternative, yet compatible, CMS without the Gutenberg block editor.
The 37th plugin is Series Index.
Displays Index of Series Posts using series-index shortcode. This plugin is multi-site compatible and integrates with the Toggle Show/Hide plugin from azurecurve. The shortcode can be used on posts and pages; the format of the index and other options are user configurable through an admin page.
Two custom fields (Series and Series Position) need to be added to each post in the series; these fields are used for selecting the posts and ordering them when the index is displayed; series index post should be Series Position of 0 (this is used for determining the link for the title).
Shortcode [series-index] is placed in the post where you want the index.
Shortcode [series-index-link] can be used in a post a link back to the series index (Series Position = 0) post using the series title as the link text; [series-index-link]alternative text[/series-index-link] to display text different to the series title. title attribute can be used to create link to other series index post; e.g. [series-index-link title='Implementing Jet Reports' /].
This plugin is multisite compatible; each site will need settings to be configured in the admin dashboard.
