This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

Post Index


Here, you will find a page where the plugin is in use or have a look at the screenshots page to see it in action.

This plugin summarises all found blog posts added to a specific category or of a specific post type and lists them alphabetically or grouped by the used subcategory. Additional custom fields could be used to display links to other pages or additional information to a post.

Upcoming features:

  • Customisable templates for the index entries to add any additional information:
    • additional text
    • custom field values
    • subcategories
  • Or any idea, you post me 🙂


  • A sample page containing the shortcode [post-index].
  • The tag in the page editor.
  • The post editor and the new custom fields.
  • Settings page to adjust the configuration of the plugin.


This section describes how to install the plugin and get it working.

  1. Upload the plugin folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Please define your custom fields and custom titles in the settings page
  4. Place [post_index] or [post_index category='CategoryName'] in your page or post to display the index


Why does the index not appear?

Did you use an existing category or custom post type?

How to change the grouping?

The following groupBy clauses to be used in the shortcode [post_index groupby=""] are supported:

  • firstLetter – Groups the posts according to their first letter
  • subcategory – Uses the subcategory of each post as its group key.
List of supported attributes for the shortcode

The base shortcode is [post_index]. You can add any of the following attributes to change the output of the index. There are some options which makes no sense to combine. For example to use the category and categoryslug attribute as they will both indicate which category has to be used.

  • category: Lists all entries that are in the given category, searched by it’s name.
  • categoryslug: Same as category but searched by the slug.
  • groupby: Grouping as explaned in How to change the grouping
  • post_type: The index will be build for the given post type instead of the standard type post. Please see WordPress Codex, Post Types for details.
  • columns: The amount of columns. Default is 1.
  • show_letter: If set to false, the grouping letter will not be generated.

This plugin did exactly what I was looking for; an easy way to neatly organize and display all custom posts by category. Simple but awesome!

I'm using only very basic functionality - page with [post_index] - and it works really good. I even removed some code from the plugin, since it was too complicated for me. 🙂 Thanks for a plugin.
