We'll create fresh WordPress site with Custom Field Taxonomies installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Custom fields are great for storing various meta data about a post. However, if you routinely need to display posts that have a certain custom field value, you should consider switching to a custom taxonomy, which is better suited for grouping posts.
With this simple plugin, you can convert all custom fields with a certain key to terms in a certain taxonomy, while maintaining the post association.
Note: If you’re looking for the old version, see Custom Query Fields
