PCP Linkflow Engine

Description

PCP Linkflow Engine gives you complete control over every URL on your WordPress site. Whether you need to remove the /product/ prefix from WooCommerce products, add a custom base to a taxonomy, or restructure your page URLs — this plugin handles it all from a clean, modern admin interface.

No code required. Changes take effect immediately with automatic rewrite rule flushing.

🔑 Key Features:

Post Type URL Control
– ✏️ Set a custom slug for any public post type (e.g. /shop/ instead of /product/)
– 🗑️ Remove the slug entirely — serve products, posts, or CPTs at root level (e.g. /jacket/ instead of /product/jacket/)
– 📄 Full support for hierarchical post types like Pages (e.g. /pages/about/team/)
– 🛒 WooCommerce compatible — works correctly with the shop page, product archives, is_product(), and all WooCommerce template hooks

Taxonomy URL Control
– ✏️ Set a custom base for any public taxonomy (e.g. /topics/ instead of /category/)
– 🗑️ Remove the base entirely — serve term archives at root level (e.g. /clothing/ instead of /product-category/clothing/)
– 🌳 Full support for hierarchical taxonomies — sub-terms work correctly (e.g. /clothing/accessories/)
– ✅ Correct is_tax(), admin bar links, and taxonomy templates when base is removed

Developer Friendly
– 🔌 Filter hooks: pcplfe_post_type_slug, pcplfe_taxonomy_slug, pcplfe_permalink_structure, pcplfe_remove_post_type_slug, pcplfe_remove_taxonomy_slug
– 🌐 REST API — read and write settings via /wp-json/pcplfe/v1/
– 📦 Import / Export — back up and restore all settings as JSON
– 🧩 PSR-4 autoloaded OOP architecture under the PCPLFE\ namespace

Modern Admin UI
– 🎨 Clean, Tailwind-inspired design with toggle switches
– 📑 Tabbed settings for Post Types and Taxonomies
– 🔄 POST → Redirect → GET pattern — no duplicate saves on refresh
– 💾 Active tab preserved across saves and page refreshes
