Readme

Word Filter Plugin

A lightweight WordPress plugin that lets administrators define a comma-separated list of words and automatically replace those words in post and page content.

This is a small WordPress plugin project created to demonstrate basic plugin development concepts, including admin menus, WordPress options, hooks, nonce verification, capability checks, sanitization, and custom admin styling.

Features

  • Adds a dedicated Word Filter menu to the WordPress admin dashboard
  • Accepts a comma-separated list of words
  • Stores the configured word list using the WordPress Options API
  • Filters post and page content using the the_content hook
  • Replaces matching words with &&&&
  • Includes nonce verification and administrator capability checks
  • Loads custom CSS only on the plugin's admin page
  • Uses a custom SVG admin menu icon
