Primary Categories

Description

WordPress plugin for setting and displaying primary categories for posts and custom post types*.

This plugin creates a meta box on the post edit screen titled “Primary Category” containing a drop down menu populated with all categories associated with that post**. Selecting a primary category and updating the post saves this data into a custom field with a meta key of “primary-category”.

To display a list of all posts with a particular primary category, use the shortcode [primary-category name=”cat_name”] where cat_name is the name of the primary category you wish to display. If a name is not specified, the shortcode will default to all posts with “uncategorized” set as the primary category.

*Note: Custom post types must support both categories and custom fields.

**Note: As new categories are added to a post, the post must be updated before those new categories will be available for selection as a primary category.

FAQ

How can I access the primary category data?

A post’s primary category is stored in the post meta under the key ‘primary-category’.

What shortcode can I use to display posts with a particular primary category?

[primary-category name=””]

*Note: Name should reference the primary category that is to be displayed, if no name is specified, the name parameter defaults to ‘uncategorized’.

Why isn’t the category I added available as a primary category?

Users must update a post after adding a new category before that category will be available as a primary category.

Reviews

Well structured code, works as expected

The plugin does just what it says. The code is well-structured and seems very lightweight.

What would make it 5 stars were:
– possibility to control which post types the plugin applies to by filter
– localization
– (perhaps out-of-scope) allow developers to control which taxonomy is used on each post type by filter (custom post types often have custom taxonomies as well)

Works fine,thanks
