Great tutorial.

Is that anyway we sort taxonomy term by meta_value? or can I retrieve taxonomy terms data using get_terms where $args = array (‘orderby’ => $meta_key or $meta_value)?

Thanks very much,

Select term_id from taxonomy_term table

I think there are some plugins that provide some higher level support for adding metadata to custom taxonomies.
http://wordpress.org/plugins/taxonomy-metadata/

I haven’t used the plugin so I don’t have any details, but it (or others like it) might be a good starting point if you want to write your own plugin. Or you can just use that as a base, and built on top of it.

I’m afraid I’ve never written a WordPress plugin, but if I understand your post correctly, it sounds like the setup for exactly what I hope to do: Beyond “Name,” “Slug,” and “Description,” there are some additional custom properties that I’d like to be able to specify for the tags on my (customized, self-hosted) WordPress site. So I’d like to add some custom input fields to the “Add New Tag” interface.

In the hopes that your sample code would make just such a new custom field, I familiarized myself with the basic structure of a plugin (including registering activation function and then calling the admin-init function), and I built your sample code into what I think should be a working plugin. (I even retained “shiba_term” as the value of $type–figuring I could start customize the names after I got it working). Installing and activating it doesn’t create a new field, though–I’m sure because I’m doing something wrong and don’t know it!

I’m certain I’m being a pest by replying to your lovely tutorial with the ultimate newbie question, but would much appreciate any guidance you can offer–even so much as pointing me to a good source where I can pick up the basics of writing/implementing plugins?

Please do email me if you can spare the time and patience, and I can send you what I put together (I tried to paste it in this comment but I see that doesn’t go through).

Many thanks!!! (And what beautiful artwork throughout your site–really counteracts the stress I usually feel when grappling with code!)

I have tried to contact him but it seems to be very valuable in its responses… 🙁

Sorry, I am not familiar with the plugin. Best to contact the plugin author.

:lots of code:

Can we help me???
thank you very much!!

The downside here is creating that new table. In 2.9 we didn’t have any other options, but now in 3.0+ you can accomplish it with a custom post type.

The code in this pastebin is an EXAMPLE and hasn’t been thoroughly tested.

Feedback is appreciated.

Hi James,
Congratulations on your new plugin release and thanks for your comment. I will definitely check your plugin out. I truly enjoy this side of the WP community – the sharing of ideas, code, and encouragement.

Merry Christmas and Happy Holidays!

Just wanted to let you know that your blog definitely in part inpired me to write my Term Menu Order Plugin (released just today). The other inspiration was that I needed the functionality for a site I was working on.

The key insight I got from your blog was looking at terms as potentially the same as posts in ways that could be surprising (i.e., the termmeta table you use here inspired me to consider simply adding a menu_order column to the terms table).

As a point of relevance to this particular thread, dbDelta didn’t work for this either, as it filters out ALTER TABLE queries (looks like it only accepts CREATE TABLE, CREATE DATABASE, INSERT and UPDATE).
