## Description

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](https://codex.wordpress.org/Custom_Taxonomies),
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](https://wordpress.org/extend/plugins/custom-query-fields/)

## Installation

 1. Unzip the archive and put the folder into your plugins folder (/wp-content/plugins/).
 2. Activate the plugin from the Plugins admin menu.
 3. Go to Tools -> CF Taxonomies

## FAQ

  Error on activation: “Parse error: syntax error, unexpected…”

Make sure your host is running PHP 5. The only foolproof way to do this is to add
this line to wp-config.php (after the opening `<?php` tag):

    ```
    var_dump(PHP_VERSION);
    ```

The plugin has not been updated since 11 years. When migrating from php 7.4 to 8.1,
it causes an blocking error.

Well the plugin does exactly what it should do. 4 stars because documentation is
poor. Hint: If you have tags seperated by comma then tags will be converted into
two taxonomies.

It may be 3 years old but it worked for me just now. I would have given it 5 stars
but (be aware) it deletes the custom field that it converts. I would have preferred
that to be optional. Anyway, thanks to the dev. Saved me having to write a dodgy
SQL query.
