Multisite Taxonomies

A WordPress plugin

Multisite Taxonomies brings the ability to register custom taxonomies, accessible on an entire multisite network, to WordPress.

Master branch:

Coding standards

We follow WordPress Coding Standards and enforce them using PHP Code Sniffer.

To test localy simply run:

• $ composer install (if you haven't already)
• $ ./vendor/bin/phpcs ./

Dependencies:

• Composer (globally installed)

How to get started?

• Start by copying the plugin to your website's WordPress plugin directory.
• Activate the plugin.
• A Multisite Taxonomy menu will appear in the admin but it will be blank.
• Add taxonomies to the website by using register_multisite_taxonomy called on the init hook. We would recommend doing this in a separate plugin of your creation.
• Multisite tags can then be added to posts through the post edit screen on any site on the network.

Register Taxonomy Example:

add_action( 'init', 'register_multisite_taxonomies', 0 );

/**
 * Load in all taxonomies.
 *
 * @return void
 */
function register_multisite_taxonomies() {
    /**
     * Load taxonomy for Tags
     */
    $labels     = array(
        'name'                       => __( 'Tags', 'hsph-plugin-tagging' ),
        'singular_name'              => __( 'Tag', 'hsph-plugin-tagging' ),
