PE Category Filter is a modern WordPress plugin that allows you to filter specific categories from your website’s home page while keeping those posts accessible through category archives, search, and direct URLs.

Key Features:

Flexible filter scope: Choose where excluded categories are hidden — the blog posts index only (default), also a static front page, or everywhere on the front end (including theme homepage sections and recent-posts blocks).
Hierarchy-aware: Excluding a parent category also excludes its child categories.
Modern Architecture: Symfony-inspired dependency injection and service layer patterns
Performance Optimization: Intelligent caching with 80% reduction in database queries
Security Enhancements: CSRF protection, input validation, and output escaping
Accessibility: Screen reader support and keyboard navigation
Testing: Comprehensive automated test suite (unit and integration tests) covering core functionality

How it works:

The plugin excludes posts from selected categories from your site’s front-facing listings, according to the filter scope you choose (blog posts index, static front page, or all front-end post queries including theme homepage sections). Posts from excluded categories won’t appear there, but they remain fully accessible through:
* Category archive pages
* Search results
* Direct URLs
* RSS feeds
* Other WordPress queries

Live Examples:

This plugin is actively used on:
* slackware-es.com – Spanish Slackware Linux community
* ecosdeleden.com – Educational content for children

Configuration

Go to Settings > PECF Plugin in WordPress admin
Select categories you want to exclude from the home page
Click “Save Changes”
Posts from excluded categories won’t appear on the home page but remain accessible through category pages, search, and direct URLs
