Radio Buttons for Taxonomies

Description

Replace the default taxonomy boxes with a custom metabox that uses radio buttons… effectively limiting each post to a single term in that taxonomy.

A plugin options page allows the user can select which taxonomies she’d like to switch to using the custom radio-button style metabox.

Originally based on the the class by Stephen Harris

Support

Support is handled in the WordPress forums. Please note that support is limited and does not cover any custom implementation of the plugin. Before posting a question, read the FAQ and confirm that the problem still exists with a default theme and with all other plugins disabled.

Please report any bugs, errors, warnings, code problems to Github

Screenshots

Installation

1. Upload the plugin folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Go to Settings > Radio Buttons for Taxonomies and use the checkboxes to indicate which taxonomies you’d like to use radio buttons

FAQ

Why do the metaboxes have a “No {$taxonomy}” ( ex: No Genre ) radio button!?

This was a feature added in version 1.4, but due to some faulty logic on my part probably wasn’t showing it everywhere that I intended.

It has come to my attention that not everybody likes this feature, so I have enabled an easy way to disable it for taxonomies that you wish to make mandatory. Simply add the following to your theme’s functions.php or your site’s custom functions plugin.

add_filter( "radio_buttons_for_taxonomies_no_term_{$taxonomy}", "__return_FALSE" );

So for example, to disabled the “No term” option on a taxonomy called “genre” you’d do the following:

add_filter( 'radio_buttons_for_taxonomies_no_term_genre', '__return_FALSE' );

This is exactly what I was looking for

There would still be a small improvement. There should be an option to pre-select a category by default when a new post is created. And the option of whether a category can be removed should also be possible in the global settings.

Important plugin

Great plugin.

Good, but limited

The plugin does what it says it will do regarding non-hierarchical taxonomies. However, I realized that this is of limited utility to my application because all of my taxonomies are hierarchical. If a Pro version were available to allow mandatory selection from only the first-level children terms of a specified parent term, then I would be very interested in that. If that is a possibility, please let me know. Thanks.

Excellent
