Here, like Tom does well, I am just noting some code thinking in case it gets fuzzy later.

Maybe this is an edge case that almost no one will face. A project I am working on now has custom post types I inject via the handy plugin. As it turns out, maybe for the theme I am trying, when displayed, it does not show any of the taxonomies it is associated with. A theme of course could not anticipate what I am doing,

Normally, this is something one puts into a custom theme template; often a theme has some kind of “get post meta” function built in leveraging the function get_the_term_list().

But in the project I am fleshing out, I am not formatting output as theme-templates, but user configurable ones they edit as content blocks (with placeholders populated by shortcodes).

I searched in vain for some plugins that would offer a shortcode that might then output the taxonomy a post/content type belonged to. It might be out there, so I came up shy.

So here is where I rolled up my sleeves… no they were already rolled, but wrote my own shortcode functions, which can go into a plugin or just added to a site with the Code Snippets plugin. My goal is here is something independent of the theme itself.

First is a [taxlist] a shortcode for displaying the category-like taxonomy a post belongs to, producing an HTML ordered list of the taxonomies with links to view their archives. It offers optional parameters:

  • taxonomy – the slug name for a custom taxonomy; default is category
  • id – optional if used on a different context than within a given post to target a specific content item (I did not need this but thought it useful). Defaults to the item in view
  • list_type – it might be useful sometimes to have an ordered HTML list, default is ul
  • class – optional CSS class name for formatting purposes
  • description – whether to include the taxonomy description or not

I made a second function for a case where the taxonomy is more like tags, and the display is like a single line string, separated by default, commas. This ends up being almost a direct path to the built in function.

Again, this could be of little use to anyone, but what I so enjoy about WordPress is often I can find plugins to do what I need, if not there is likely custom code swimming out there in StackExchange (ir blogs, those old time things), and if that fails, I can cobble my own.

And that all feels like my kind of space to build in.


Image Credits: When thinking of this post, my associative brain cells went to the old “What’s My Line?” TV show. The Wikimedia Commons image was perfect- Whats My Line original television panel 1952.JPG licensed as public domain with some long legged reasoning (age, lack of copyright, probably contestable, sue us all). I Photoshopped in the change of Line to Taxonomy, shoving wood around behind it, and changed the name labels. I may have spent more time futzing on the image than writing the post, both of which took longer than writing the code.
