Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/torwald45/wp-snippet-subcategory-redirect-woo/archive/refs/heads/main.zipNo built-in updater. New versions won't appear under Dashboard → Updates. Install new releases yourself, or let Git Updater track the repository.
WP Snippet: Subcategory Redirect Woo
Woo allows accessing subcategory pages via short URL (without parent slug), creating duplicate URLs for the same content. This snippet detects short URLs and performs 301 redirect to the canonical full URL with parent slug.
Example
Short URL (duplicate):
/product-category/child-category/
Canonical URL (correct):
/product-category/parent-category/child-category/
The snippet redirects the short URL to the canonical one with 301 status code.
Requirements
- WP 5.0 or higher
- PHP 7.4 or higher
- Woo with hierarchical product categories
