Libre Breadcrumb Permalinks

Description

By default, WordPress adds a base prefix to taxonomy URLs — /category/, /tag/, or any custom taxonomy base. This plugin removes those prefixes and replaces them with breadcrumb-style paths built directly from the term hierarchy, giving clean, readable URLs that reflect the content structure:

/parent-term/child-term/post-slug/

For custom post types associated with a taxonomy, the full term path is used as the permalink base. For non-hierarchical taxonomies, only the term slug is used.

It supports:

  • Hierarchical and non-hierarchical taxonomies
  • Custom post type permalinks built from associated taxonomy term paths
  • Automatic detection of public taxonomies (including category and post_tag) and CPTs
  • Configuration via filter for fine-grained control

The plugin works at the permalink and rewrite layer and does not modify stored slugs or post content.

Installation

  1. Upload the plugin folder to /wp-content/plugins/
  2. Activate the plugin

The plugin works out of the box and has no administration interface. For custom configuration, use the lbp_config filter (see FAQ).

FAQ

Does it create database tables or store plugin data?

No. The plugin only generates rewrite rules and filters URLs. Nothing is stored beyond WordPress’s own rewrite rules cache.

Can I choose which taxonomies and CPTs are affected?

Yes, via the lbp_config filter. Plain values declare a taxonomy whose base will be stripped. String keys declare a CPT => taxonomy association — the taxonomy base is also stripped, and the CPT permalinks are built from the term path.

add_filter( 'lbp_config', function() {
    return [
        'category',                 // strip base from this taxonomy
        'post_tag',                 // strip base from this taxonomy
        'my_cpt' => 'my_taxonomy',  // strip base + build CPT permalinks from term path
    ];
} );

Without this filter, the plugin auto-detects all public custom taxonomies, including category and post_tag, and CPTs.
