Custom Post Type with AJAX Filter

Overview

For MessageWatcher.com, I built a custom WordPress plugin that powers the site’s support section — an efficient, searchable knowledge base designed for speed and simplicity.

The custom post type with AJAX filter plugin registers a new post type, “Support,” allowing admins to create categorized support articles directly in WordPress. Each time a post is saved, the content is also written to a text file for fast retrieval outside of the WordPress database.

Key Features

• Custom Post Type – “Support”:
  Centralized system for managing all customer support content within WordPress.
• Auto-Generated Text Files:
  Each saved post exports to a lightweight .html file, minimizing database queries and improving page-load performance.
• Dynamic, Filterable Front-End Display:
  The support page lists all topics with built-in search and category filters.
  Content is loaded via jQuery + AJAX only when requested, keeping the main page exceptionally fast.
• Direct Linking for Support Responses:
  Admins can share direct URLs to any topic, making it easy to guide users to the right solution.
• DIY User Support:
  Visitors can quickly search, browse, or filter articles to find their own answers — no page reloads required.

Result

• A streamlined, database-light support portal that loads nearly instantly.
• Admins save time managing content, and users get a fast, intuitive way to find answers or request help.
