Tag Entry

If you find the hook (e.g. https://codex.www.ads-software.com/Plugin_API/Filter_Reference ) for retrieving the tags, you could possibly filter them. Or you write something with jQuery that hides all tags that are not in a group (by their class tag-link-… ). That would allow you to have there a pull-down menu with the groups and dynamically hide tags that are not in the selected group.

I’m wondering if I could just modify the code that generates the original tag entry box that shows up on the post edit page. Here’s my situation: I have a bunch of video game reviews, and they have publisher, developer, and platform fields that I want to have as tags. Your plugin works great to keep them in their groups, but I need to have an entry field for each of those. A drop-down or checklist will work for the platform group, but I think the publisher and developer groups will have way too many entries for that, so I may need something that works like the the original tags box.

If you have any ideas, I would appreciate it. Thanks!

I would avoid to modify the code of the core WP. Every time there is an update you will have to re-apply your custom changes.

The drop-down menu was my idea for selecting the tag group, so that you can select which tags to show in the original tags box.

You could probably look into the possibility to add multiple taxonomies to the reviews (what are now groups would become taxonomies).

I will keep thinking about other ways to accomplish it with tag groups, but it looks like needing some extensive work.

Yeah, that was what I was afraid of.

I have looked at what a certain plugin (ComicEasel) does for this type of thing on another website that I maintain. It is for webcomics, and it uses the wp_term_taxonomy table to differentiate characters, chapters, etc.

I’m not really that familiar with the code of WP, so I may have to resort to hiring someone to write a custom plugin. That, or spend several months learning how to make one.

You could try the plugins that handle custom taxonomies, e.g. https://yoast.com/wordpress/simple-taxonomies/
