The ultimate auto-tagging plugin for WordPress.
NOTE: The plugin is now being maintained on GitHub, so please do contribute all your questions, comments, suggestions, fixes and improvements with me <a href="https://github.com/holisticnetworking/title-to-terms" rel="nofollow ugc">here</a>.
Title to Terms Ultimate is for every WordPress admin that needs tags, categories and other taxonomies filled out automatically. For each post type in your WordPress installation, T2TU will allow you to assign a taxonomy to be automatically updated with keywords pulled from the title of the post.
Every time a post gets saved or updated, T2TU analyzes the title of the post for usable keywords. A list of user-configurable “Stop Words” is checked by the parser, so that words like “I” or “going” don’t get made into ultimately useless tags.
<ul>
<li>Converts keywords in post titles to terms in any taxonomy</li>
<li>Includes user-editable list of words to be ignored.</li>
<li>Ignore list can be reset to default at any time.</li>
<li>Converts on save, not publish.</li>
<li>Configurable to either add new terms or append the list of terms.</li>
</ul>
Multisite admins take note: this plugin is especially helpful if you’re building a community-based site where tagging is important and your bloggers are not always diligent about tagging.

Title to Terms Ultimate

The ultimate auto-tagging plugin for WordPress.

Supports adding one or more taxonomies (either hierarchical or tag) to any objects registered on your installation.
This plugin started as a functional conversion from <a href="https://wordpress.org/plugins/simple-taxonomy/" rel="ugc">Simple Taxonomy</a> and developed on WordPress 5.1-6.7 with PHP 7.2-8.3.
This plugin allows you to add a taxonomy just by giving them a name and some options in the backend. It then creates the taxonomy for you and takes care of the URL rewrites.
It provides a widget that you can use to display a “taxonomy cloud” or a list of all the terms; it allows you to show the taxonomy contents at the end of posts and excerpts as well. To increase flexibility, a shortcode and block has been provided to output these terms wherever desired.
You can also export the Taxonomy definition to include it directly in your own code.
You can also create terms easily by typing them into a list; or by copying them from an existing taxonomy.
A tool has been provided to support changing the taxonomy slug. Any terms and their usages will also be linked to the renamed slug.
For admin screens displaying multiple taxonomies it is possible to define their display column order.
A tool is provided to merge a number of terms within a taxonomy into a single one. All usages of the selected terms are changed to the merged one.
Options are provided to add a selection dropdown in the admin list and to define minimum and maximum required term counts using posts of selected statuses (and not only “published”). [Term counts with WP 5.7+ requires version 1.3+ of this plugin.] These capabilities are available for any taxonomy whether defined using this taxonomy or elsewhere.
For full information go the <a href="https://github.com/NeilWJames/simple-taxonomy-refreshed/blob/master/docs/readme.md" rel="nofollow ugc">Simple Taxonomy Refreshed</a> page.
When using the admin screen, additional information is available in the help pulldown area.
<h3>Migration Notice</h3>
<h4>From Simple Taxonomy</h4>
It is a drop-in replacement for <a href="https://wordpress.org/plugins/simple-taxonomy" rel="ugc">Simple Taxonomy</a> – using the same options table entry.
If this is installed, deactivate it first.
However since this plugin uses the Simple Taxonomy options data to save setting it up again completely if you wish to revert, before deactivating you can use the Simple Taxonomy export function to take a copy of your data.
NB. The Export/Import functions are not compatible between plugins. So you need to use the file made with its version of the plugin.
To have the Taxonomy metaboxes available in the Block Editor, ensure that “show_in_rest” has been set to true.
When migrating and before an update to the existing parameters, the taxonomy will treat “show_in_rest” as true. If not wanted, set to false.

Simple Taxonomy Refreshed

This plugin provides a no-code facility to manage your taxonomies - either by defining your own or by adding additional function to existing ones.
